These consumption spikes go past the Solar energy being limited suggesting were drawing from the grid! Thank you. Export limiting generally isnt permitted. But it seems the situation has been changing for the better in the last couple of months in a number of affected areas. Youre using a total of four kilowatts to cook your lunch, so your home is exporting 4 kilowatts, which is below the limit. 0000008043 00000 n Weve got a system that can be left alone in my opinion, so adding say 6.6kw and a 10kw battery makes good sense but what a task. The standard relating to solar inverters is about to change. I think that the limiter can connect only to one inverter and not two at the same time. AC Output Data This is sufficient to charge a battery, although larger solar systems generally improve the return from batteries. Rooftop solar works by turning sunlight into electric power. And Set Power Limit to 100%. The Good: In these locations, properties can usually install up to 10 kilowatts of solar inverter capacity if they have single-phase power and up to 30 kilowatts with 3 phase power. But if you dont use much electricity it may need to be very small, as I explain here: https://www.solarquotes.com.au/blog/zero-kw-export-solar/. 2. No unfortunately. Worried the impact this will have currently when we charge an EV in the near term. Heres the Fronius Smart Meter that you need if you want to export limit a Fronius inverter it will add about $500 to the cost of the system: An example of how export limiting works You have an inverter thats exported limited to 5 kilowatts. I was really keen for this system with a battery as most of my power is used at night and I like the idea of power during blackouts, which do happen quite a lot here. The good news is, if you had a total of 6.6 kilowatts of solar youd probably loose very little due to export limiting if you consume half the output of a 3 kilowatt system and can export 3 kilowatts. If you dont get under the covers and look carefully at the logs you might miss this, or think it is a cloud coming over, rather than voltage triggered throttling. I am a total newbie to this but I am unclear why export limiting is good? Thanks Ronald! In an Enphase system, that is with the Envoy-S with consumption monitoring. Definitely, thats an inverter that is export limited to zero. 0000004059 00000 n A condition of this basic connection offer is that all inverter energy systems must have the volt-watt and volt-var response modes enabled with the following settings: It also allows you to focus on increasing your self consumption which in turn provides a better return on investment. See image at http://www.johnrogers.com.au/battery_charging_noon.jpg. They did say that with future upgrades we could reapply, but I cant find a way to do this. given that we are working from home all the time these days. Ronald Are Tesla Powerwall smart enough to let majority of power export to grid and only start charging battery as inverter approaches its export limit? A small solar system can be financially viable. The reason why your sisters inverter is different from yours is your Goodwe would be because yours has a current transformer device that lets it limit the amount of power it exports to the grid. Its the same with kW and hours of solar electricity production. In future, will powercor allow export limit if they upgrade transformer? 0 At the time of the powerwall install I also had the Gateway installed at an extra cost so I could keep using the generated power from the powerwall and during solar production when the powergrit fell out without danger for the grit workers because the Gateway instantly falls and prevent power to the grit. Im in the same situation, except I have an existing 5kW system. But given average voltages are probably well above what they should be in lots of places, and once you factor in your local voltage rise, and pretty low values under AS4777 etc, there is not much room to play with until the distributors get the act together and deliver us power that better matches the 230v standard they are required to deliver us. Hi All, I am on my second Tesla EV and the new one has a rage of 700km if youre not a lead foot. 0% But depending on our network capacity, export constraints may influence the size of the unit they install. We installed 4.5kw with a 5kw inverter in 2014. Youll also start receiving the SolarQuotes weekly newsletter, keeping you up to date on all the latest developments on Australias solar scene. In most cases, if you had your envoy shut off, the micros would start and work on their own and independently of the envoy, and in fact of each other. Nominal Output Power (W) 5000 I wouldnt drive anything else. Assume positive intention.4. 5 kilowatt inverter + 6.6 kilowatts of solar panels (no export limiting): 0%, 6 kilowatt inverter + 8 kilowatts of solar panels: 4% loss, 7 kilowatt inverter + 9 kilowatts of solar panels: 8% loss, 8 kilowatt inverter + 10 kilowatts of solar panels: 13% loss, So, on the one hand, the Victorian Government is. Theyd be higher for a sunnier location such as Perth and lower for cloudier places such as Melbourne or Hobart. Hi All. Solar customers who currently have a limit on the amount they can export are invited to contact Powercor to reapply for an export agreement based on the greater capacity now available on the network. Generally however, I can advise that Powercor intends to upgrade the network over the next 5 years, starting in January, however, the specifics of where upgrades are happening and the order has not been decided. No-one seems to have replied Dirk, so I will try. What inverter do you have? 0000028229 00000 n Aside from that, when you have high resistance lines, there is a voltage drop over their length. As a single example, the Renault Kangoo ZE van (I think that it is the only battery powered cargo van currently available in Australia) has a 33kWh battery, and, To go further, Kangoo Z.E boasts a Z.E 33 (33kWh) battery, Powercor says it has contacted all solar customers within the previously impacted areas to let them know about the companys progress and to encourage them to consider reapplying for exports. My solar installer applied to Powercor to install a 5.4kw system at my Point Cook address. 100% The word first can be confusing. So if an inverter that is export limited to 5 kilowatts is providing 8 kilowatts of power, none of it will go to waste provided the home is consuming at least 3 kilowatts at the time. Powercor's network solutions manager Claire Cass said of 32,580 customers connected to solar with Powercor in the last 18 months, only 2023 could not export power. I believe it must have been set up during installation, but the installer company claims that this is handled by Growatt themselves.

Unfortunately, SAPN wont allow more than 5 kilowatts of inverter capacity on an SWER line. Is this correct? 0000005986 00000 n ( Powercor claims 30% increase in rooftop solar export approvals Victorian network service provider Powercor claims a major works program designed to alleviate grid congestion in areas of high rooftop solar PV penetration has boosted the approval rate for new solar connections to export excess energy to the grid by an impressive 30%. NSWs Ausgrid Network Area: This covers East Sydney, Newcastle, and out to Merriwa. As your sister can presumably export as much power as her solar inverter can produce it wouldnt need this device. But if people send a lot of power into the line then the voltage at the far end, instead of being lower than at the sending end, becomes higher. So if your home isnt currently drawing power you wont know from looking at the display if its capable of producing the maximum 5 kilowatts or if it cant provide more than 3 kilowatts. But there is also the DNSP rules which need to be followed. Thanks Ron. Hi i want to install solar with no power But your situation is complicated by already having a 3 kilowatt system. Victorias Powercor area: Western Victoria, including a large portion of West Melbourne. But a sub optimally configured grid sometimes forces installers into implementing setting that are probably less than ideal if the high voltage events in the grid were just occasions where there is too much generation and they do want have all generators throttle back to allow some time for rebalancing supply and demand. Rubbing salt into the wound were situations where someone was zero export limited while their next door neighbour wasnt. The current Envoy they will be selling is the Envoy-S. Before that was the straight Envoy which did not have the consumption monitoring / metering needed to do export limiting. The installer has been able to get the system through WP in the past as the inverter can limit the export to grid to 3kva. He's been reporting on Australian and international solar energy news ever since. An option is to take your pumps off-grid and run them independently off a separate off-grid solar system. A man named Canute, proved that, centuries ago. Put down your weapons.3. South Australian solar panel owners can currently export 5 kilowatts of electricity to the grid but under Flexible Exports, they could export double that amount 10kW. Information on whether export limiting is allowed can be found here, but I am going to present the information differently for both ease of use and to make my boss think Ive done something useful. Still a very long payback period, but not as long. I have a 14kW solar array running Enphase IQ7+ microinverters (43 of them) hooked up to the grid in a 3-phase configuration in the Endeavour Energy area in NSW, and they currently have the profile AU default AS4777.2:2015 30kVa, Vv, Vw set. driving range of 200km depending on ambient temperature. So if an inverter that is export limited to 5 kilowatts is providing 8 kilowatts of power, none of it will go to waste provided the home is consuming at least 3 kilowatts at the time. just wondering if anybody can shed some light on the following, This means you tend to see panels at the end of strings shutdown soonest on voltage risk conditions, as they have the highest voltage rise being at the end of the string. Notify me of follow-up comments by email. Generation sources can be, but are not limited to solar, wind and batteries. That can raise the voltage to a level dangerous to appliances. Please confirm the maximum export limit in the relevant section of this application.. Only residential homes with inverters of 5 kilowatts or less can receive the states. There are profiles that still conform the microinverters to AS4777.2:2015, but can disable Volt-Var/Volt-Watt, change the power factor to 0.9 (some grid operators require this), turn off export altogether or set specific maximum export levels like 1kW, 3kW etc., or configure to satisfy specific grid network requirements. 1. We installed solar power in November last year and were refused export (zero export). Hi But I suspect for a lot of people, the vast majority of these over voltage events are simply because the networks are running out of spec voltages. A rooftop solar system's grid export limit is determined by the local electricity network operator - sometimes on a case-by-case basis, sometimes according to an across-the-board standard, and . Okay, so that heading may be a bit of an exaggeration, but improvements the company has carried out appear to have made quite a difference. I have a 5kw solar system plus a Tesla powerwall 2 on my house . They hid the problem pretty well, because they do tend to reduce the amount of shutdowns. ) 0000037764 00000 n I have divided Australias regions into three categories: The information below assumes the property is on the main grid. Some say so you want to replace your system? When it says that you can export 5kw, does that mean you can export up to 5kw PER HOUR? Whats the logical and practical way forward? Depending on their location, some may be constrained to a lesser export level or even no exports at all. I had applications rejected, and when I asked there was NO course for negotiation or discussion its the RULES is s synopsis of the responses. Im surprised this hasnt hit the mainstream media yet. For any amount above the daily export, you will receive our standard retailer feed-in tariff of 5 . I was told that as there is an export limit of 5kW and I already have 3.5kW system, my new system will be export limited to 1.5kW. There may well be a tipping point in battery prices where a drought of mid day solar will be followed by very little evening use and possibly large numbers of households abandoning the grid altogether. My sister has the same type of inverter (Goodwe) but she lives in the Estern suburbs of Victoria and she has been exporting but her Power Limit was set OFF. Ill upgrade the Endeavour Energy area from Ugly to Bad, since things are clearly not all bad there. 0000004736 00000 n Thanks Steve 0418 815 193. A Decent Battery From sonnen. So an Enphase setup, without a continuously operating Envoy with not be providing this functionality and likely to raise some concerns in the AS4777.2015 certification process if they did not take steps to make sure these functions are always guaranteed to be implemented. Ready for some quotes? So having a powerwall is way less useful for helping with an export limit than you would think. It seems so strange that it is clear government policy to get more solar going and yet the network operators are effectively blocking it now. I have previously posted (or, submitted for posting), the proposition that what is needed, is a hybrid (not meaning in this instance, a hybrid inverter as is commonly used) inverter that is like a cross/combination, of the Goodwe GW5000-MS inverter (or, kind of, the GW10K-MS, in terms of power conversion), and the Goodwe GW5048D-ES; three GW5000-MS provides for up to 10kW of panels generating capacity, across three MPPTs (strings? Solar Analytics confirms in this scenario its only exporting up to the limit; 3kw. Your dedicated meter will inform the inverter, and it will immediately reduce the power, so it doesnt exceed 5 kilowatts1. According to NT Power and Water they will normally allow up to a 5 kilowatt inverter with single phase power and up to a 7 kilowatt inverter with 3 phase power. 5kW export limiter imposed on one inverter. Voltage (V) measured at inverter terminals embedded generation system to the CitiPower and Powercor low voltage networks. One thing I find is that Voltage control works well: instead of the inverter resetting if the voltage gets too high, my inverters roll back output, so it actually helps my neighbors too because their inverters reset less often. Means that it caps the amount you can reduce your bills for power used outside of daylight hours? Allows installation but has a zero export limit. 1. As has been explained (and COSTED) on previous occasions batteries are VERY cost-effective.IF you stay away from the hi-tech/overpriced/dependence-creating/unproven battery-systems advocated by commercially self-interested parties. 0000037419 00000 n 0000011077 00000 n Max. hooked up to an energy efficient 44kW motor for a real-world DC Input Power (Wp) 10000, from its published datasheet. 0000001260 00000 n ARTICLE WRITES: Queenslands Energex area: South East Queensland. I was told to set Power Limit to ON. After all, Im a big picture kind of guy. 0000038296 00000 n VAr (var % rated VA) What am I missing? Would the gateway signal the micro inverters to shut down one at a time, or to all reduce output equally? Limited export means more power for home If your system has a limit on how much it can export then it means more power will get used in your home instead. Fronius Wattpilot: A Smart EV Charger With A Short Warranty, You Wont Believe How Dumb The NSW Governments New Battery Calculator Is. I will update the article with the information. Have I been conned into believing I could produce up to 6.6kW myself, but in fact the maximum my inverter will ever allow through to the meter (and to my house) is only 5kW? Can I share my power excess with me neighbour? Is there anything that can be done about it? Good question Tony. In addition, all modern solar inverters must comply with AS4777.2015 at least. We want to add a battery and it seems logical to add more cells also to another inverter/battery setup. Interesting article. 0000038752 00000 n If you are using Enphase microinverters which is extremely likely the whole system can be export limited using the Enphase Envoy gateway. I have solar on my house and having it installed at an investment property, but not sure what to do now as there will be no benefit of feed in tariff. MPPT2 always shows better performance than MPPT, usually quite significantly better. Now, there are quite a few profiles on offer that can be programmed into the microinverters. Its moderately cheaper and the solar feed-in tariff youll receive will lower your electricity bills and increase the amount of clean energy available for others to use. Select the AS/NZS 4777.2:2020 Australia A setting. Its also unusual for a large solar system to have all the panels facing the same direction. But it took him about another ten years to focus on it in a way that wasnt really stupid, Good Article. I have 3 x PV systems on one phase. Seem most solar places, even the ones the go on about how good they are, arent that good when presented with this, what seems to be a conundrum for them. Normally it makes more sense to buy a second, separate system, than to expand an existing one. But whether or not extra solar capacity will pay for itself is another matter. Swearing revenge, he began his lifelong quest to reduce the harm the environment could cause. Plus a Tesla Powerwall 2. 260 Up until quite recently, Powercor had been informing a large proportion of households looking to install new solar systems they will have to cop a zero export limit due to high congestion created by exports from existing systems. 2. I realise that Australian legislatures do not care about the future, but, the future is coming, whether the legislatures like it or not. Fronius Wattpilot: A Smart EV Charger With A Short Warranty, You Wont Believe How Dumb The NSW Governments New Battery Calculator Is. Do you know the situation here? 100% Is it the 6.66 kW, as the 1.3 overload factor of a 5kW inverter, or, is it the maximum allowed (by the manufacturer) panels generating capacity, for an inverter that is allowed by a state/territory government? 220 But, now, Goodwe have the GW5000-MS inverter, which, from what I have read, is apparently allowed in WA, for a single phase SWIS grid connection, and, that inverter is a 5kW inverter, that has a maximum panels generating capacity; While export limiting is possible its not always approved. Your meter is on the connection between the mains network on one side and the combination of your inverter and your loads on the other side. Also, given that export limited inverters (supposedly) work the same, regardless of the grid to which they are connected, why is it so, that states have different rules whereby some allow export limited inverters, and, some do not? 0000000016 00000 n You could approach SAPN and ask for special permission to install more solar capacity on an SWER but I would not be optimistic about that. The new home didnt have solar. I installed 6.6kw solar panels and have Goodwe 5kw inverter and applied for export limit of 5kw. I live in Warrnambool, Victoria. While losses increase as the solar power system size goes up, even with 10 kilowatts of panels which is twice the export limit, only 13% of generation is lost. is it 10kW AC or DC?? I still dont know if they have programmed the inverter to reduce the overall output by a percentage or not. But this is at least partially because when you throttle back output, you also reduce the amount of voltage rise you are causing on your local connection to the point of interconnect which is probably contributing to the issue. Or is there a build up of voltage in the system? Am planning to install solar 6.6 kWh system and upon checking with powercor they are giving export limit as 0 kWh. (2nd one APPROVAL/SITE SPECIFIC CONDITION(s): Total Solar Export must be limited to 5kW). And, no matter how powerful, the members of the legislatures imagine themselves to be, and, no matter how trump-like, they are, they can not stop the future. Three-phase homes can install up to 15 kilowatts of inverter capacity or 30 kilowatts with export limiting, except in South East Queensland where special permission is required from Energex to install an export limited inverter over 15 kilowatts. What made the situation all the more frustrating is periods of high congestion which can threaten the stability of a local network can be quite brief. Certainly this dumb meter is not capable of sending current from the inverter selectively to my home circuits and any excess to the grid? I have an existing 3.5kW PV system with Solis inverter. The solar PV system is connected to the network via an inverter. I am a bit confused about export. IE if Im producing 8KW, the house is using 2KW it will still export 5kw? The solar installer or customer must have sought and received pre-approval from us for the requested capacity of the generator. On the main grid, single-phase properties can have 5 kilowatts of solar inverter capacity, and three-phase properties can have 15 kilowatts. you aren't allowed to export any power from your solar system to the grid. 306 47 endstream endobj 307 0 obj <>/Metadata 15 0 R/Pages 14 0 R/StructTreeRoot 17 0 R/Type/Catalog/ViewerPreferences<>>> endobj 308 0 obj <. 00@ Oo ), converting to up to 10kW of AC power, and, the GW5048D-ES provides for up to 6.65kW of panels generating capacity, converting to up to 4.95 kW of AC power, and, acting as a battery management system and UPS, when a battery system (of up to two approved, low voltage, batteries) is connected. 4. For example, our Solar Enablement program is intended to allow more customers to connect a 5kVa solar PV system with export capacity. The majority of customers are approved for the export level they request. So, the whole of the system of restrictions and available components, for domestic rooftop photovoltaic systems, needs to be reviewed, to provide for greater usage demands during peak demand hours, greater battery storage provisions (and financial assistance for householders to implement big behind the meter battery storage systems, and, regarding the fragile, decrepit SWIS grid, the allowance of large capacities of panel generation, limited export, inverters, such as the hybrid one that I proposed. But just note, not everyone Envoy has required bits to do export limiting. "Some of these customers may have received approval to export since, due to network improvements made since their connection." The naming of zones may differ between manufacturers but may appear as: Australia A - applies to the configuration of inverter settings in Victoria and all Eastern . Assume positive intention.4. The distributor deals with that by putting the voltage slightly up at the sending end. If you are export limited, the only way to implement that is with some sort of meter as Ronald says. If at any moment in time you are generating more solar electricity than you need, the excess is exported to the grid. Does anyone know how the limiter works in this scenario with 2 inverters? What I find is installers dont seem to like it when I tell them my plan. Ready for some quotes? A Decent Battery From sonnen. Our Solar & Battery Calculator can give an idea of if its likely to pay: https://www.solarquotes.com.au/solar-calculator/. The following is a list of the areas in case youve been missed. at night or not enough at day time ? Perhaps it is worth mentioning that the stricter export limitation becomes, it will make a stronger argument for batteries. The fact that export limiting is necessary is not a good thing. In my mind though the Smart meter at the box would adjust the export limit in line with what the house is consuming? This gives the advantage of having a new system covered by a new set of warranties. Why my Power Limit is set to ON with the % whereas her Power Limit is set to OFF and she has been exporting. Sorry if dumb question. And for this reasons, I have increasingly seen that it is more challenging to run micros without the envoy which would no doubt be extra code required in later versions of the envoy to enforce implementation of various AS4777 and export limiting requirements that cant be done in the micros alone. This applies to both single-phase and three-phase properties. Definition A low voltage embedded generation connection in CitiPower and Powercor is defined as "an LV EG system with a total system capacity greater than 30kVA for a three-phase IES or non-IES (excluding ESS) network connection that is: Tasmania: Under 1% of Tasmanians are on SWER lines, so the generous export limit should often be available. But there will often be times when the solar system will produce more power than can be exported, so some energy will be lost3.
