Notify me of follow-up comments by email. Put down your weapons.3. This applies to both single-phase and three-phase properties. Rubbing salt into the wound were situations where someone was zero export limited while their next door neighbour wasnt. 0000039284 00000 n both said 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. Thus, the question arises; if a single phase domestic rooftop photovoltaic system, involving a Goodwe GW-5000-MS inverter, and, 10kW of solar panels generating capacity, is installed (across up to three MPPTs), would the federal solar panels rebate apply to all of the 10kW of solar panels, or, to only the first 6.66 (or whatever is the exact applicable quantity) of the solar panels generating capacity? A small solar system can be financially viable. But it seems the situation has been changing for the better in the last couple of months in a number of affected areas. Efficiency has and will improve further over time, but never to the point of perpetuity. I do NOT have a device in my meter box that could tell the inverter anything about consumption and feed in energy. 2. An Update: I just had system installed 4 days ago in the Energex DNSP and suggest the above is perhaps not quite correct. I am trying to get a system installed (6.5k smart hybrid inverter with a battery) and have been told by Western Power that I am limited to a 3.0 kva system. A Decent Battery From sonnen. 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. Can anyone shed any light for me? Please confirm the maximum export limit in the relevant section of this application.. Its located in Ausnet Services' Distribution Area but Ausnet is not part of the CitiPower, Powercor and UnitedEnergy . Note that connections off the main grid are usually far more restricted. Your dedicated meter will inform the inverter, and it will immediately reduce the power, so it doesnt exceed 5 kilowatts1. So-called wasting of the extra electricity produced is irrelevant: sunlight is FREE, and whether I use it or not has no bearing on the environment. ARTICLE WRITES: Queenslands Energex area: South East Queensland. As discussion of the topic of export limiting, is continuing, what,if any, is/are the direct effect differences to electricity grid load (as in the load on the wires, not the load as the term used for meaning demand), between a 5kW inverter, and a 10kW inverter with 5kW export limiting? Select your country/region. Whilst this may not be technically defined as export limiting, as the inverter specifications, specify that the inverter, whilst allowing up to an overload factor of 2, will only generate up to 5kW of A/C power It would definitely be better if we didnt need to limit the amount of power solar systems sent into the grid. If at any moment in time you are generating more solar electricity than you need, the excess is exported to the grid. Select the AS/NZS 4777.2:2020 Australia A setting. Have a good christmas. 100% 0000009573 00000 n Weve seen a rapid growth in rooftop solar systems.With each installation, were facilitating rapid growth in the amount of solar capacity on our network. Anyway you are probably not supposed to be messing around with the profiles without agreement of your DNSP. While there are some energy management measures that could help around the edges, I cant think of any good solutions for the typical business. Solar Analytics confirms in this scenario its only exporting up to the limit; 3kw. Can one have micro-inverter panels without a gateway, and how would that be limited? Furthermore, the sustained overvoltage inverter protection set point shall be set to 258V. MPPT2 always shows better performance than MPPT, usually quite significantly better. 0000007554 00000 n Some manufacturers may have this pre-selected. So in effect I have two safety guards in place, 1. the 5kw limiter to the grit and 2. the extra Gateway . Solar Export Limiting: Why You Should Know About It Sometimes Powercor can reduce that to a lower figure, or even set a zero-export limit. Victoria's Powercor Lifts Its Solar Exports Game Will this mean any additional system would be limited to 0kW output?? endstream endobj 307 0 obj <>/Metadata 15 0 R/Pages 14 0 R/StructTreeRoot 17 0 R/Type/Catalog/ViewerPreferences<>>> endobj 308 0 obj <. 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. March 2022 6 Powercor means Powercor Australia Limited, ABN 89 064 651 109. portal means the eConnect portal for CitiPower and . 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. I am looking at adding a second system (6.2kW) with GoodWe inverter. (We are conected to a 25Kw transformer, with 5 consumers connected.). But it took him about another ten years to focus on it in a way that wasnt really stupid, Good Article. Theres more good news, with further improvements to come. Export limiting does limit the inverter output, but only as needed to keep the export power below the limit. Once voltage thresholds etc are configure in the profile by the Envoy at install, each micro operates largely independently. 4. In a Enphase system, only the Envoy can provide this. I have spoken to one installer , but he couldnt really help me . Enter your postcode now. 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. Wouldnt it be better for the inverter to display its total actual potential output under current conditions? South Australia Power Networks (SAPN) area: SAPN is the only distributor in South Australia. We are in an area where only about 20% of the homes have solar. But your situation is complicated by already having a 3 kilowatt system. What am I missing? So the solar inverter has to have its own energy meter installed in your switchboard one that talks to the inverter to tell it when power sent into the grid reaches the export limit. Can I share my power excess with me neighbour? I have just had a 6.6kw system installed with a Fronius 5kw inverter and am export limited to 3kw. sonnenBatterie Evo. hbbf`b``3 I j It is critical that you install an approved smart inverter and set it correctly. And, when battery powered road vehicles with adequate distance capacity (I have read that VW expects to release a battery powered station wagon, with range between charges, of 700km, in 2023 (although, unless Australia wakes up, such vehicles will be unlikely to come to this neolithic country) ) are available, and, even for the rare ones that apparently, already exist in Australia (having not yet seen a battery powered vehicle in Australia, I wonder whether they are simply an urban myth, as to their presence in this backward country), when would they get charged, if people would only charge them at home? Its only possible to go larger with a zero export limit: https://www.powerwater.com.au/customers/power/solar-power-systems/pv-class-requirements. Self confessed newbie to the mechanics of Solar so bear with me. Is this perhaps one of the well-kept secrets about the reality of residential solar production in Western Australia, one that neither the solar installers or inverter manufacturers, let alone Synergy or Western Power want to be publicly known? Point Cook Solar limit export to zero by Powercor - Solar PV discussion "Some of these customers may have received approval to export since, due to network improvements made since their connection." 11kW panels with 10kW 3-phase inverter (Fronius Symo + Fronius 3-phase meter). Its the same with kW and hours of solar electricity production. After all, Im a big picture kind of guy. 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. Heres what that means. The loss figures above are for Sydney and are affected by the climate. Solar Export Limiting or Zero Export. What Does it Mean? I live in Warrnambool, Victoria. 0000001260 00000 n Any ideas of how I can get a system that is actually going to generate enough power to charge a battery? hooked up to an energy efficient 44kW motor for a real-world essential enrgy in central west nsw (Orange) are generally restricting to max 5kw export limit regardless of 1ph or 3ph: 2 x 3ph residential applications approvals cutnpaste below only difference was one specifically stated APPROVAL/SITE SPECIFIC CONDITION(s): Total Site to be export limited to 5kW 3 phase 1.66kW/per phase (and the padmount sub for the subdivision in on the property boundary) But I can tell you a few things that might help with some of your pondering :- 1. We want to add a battery and it seems logical to add more cells also to another inverter/battery setup. Theyd be higher for a sunnier location such as Perth and lower for cloudier places such as Melbourne or Hobart. Ill upgrade the Endeavour Energy area from Ugly to Bad, since things are clearly not all bad there. But you will probably find that there is another setting that it will shutdown when 10 minute average voltage is a measly 255v. I havent made any applications yet, but Ill certainly be asking this question when I get quotes!. Regarding batteries, as we all know from our mobile phones, constantly being charged and discharged, will deteriorate much quicker than PV panels (and the same that goes for phones, laptops, and your electric toothbrush also goes for solar and electric vehicle batteries, unfortunately). Energex doesnt automatically allow inverters over 5 kilowatts to be installed with export limiting, but currently regularly grants permission for single-phase homes on the main grid to install up to 10 kilowatts of inverter capacity with export limiting. 0000010603 00000 n The standard relating to solar inverters is about to change. In reality, the losses will be considerably less. Ready for some quotes? Queenslands Ergon network area: All of Queensland on the main grid outside of South East Queensland. There is not likely to be an Enphase system without a gateway (called the Envoy with in the Enphase system), because this is needed to setup the system, configure its profiles and report production and other important functions of the system. Fronius Wattpilot: A Smart EV Charger With A Short Warranty, You Wont Believe How Dumb The NSW Governments New Battery Calculator Is. 0000027694 00000 n Is this correct? This certainly goes well beyond initial configuration and reporting. Hi Im in regional WA with a rural 2 phase supply. A Decent Battery From sonnen. If you are in the solar industry - try to get to the truth, not the sale.5. 258 My AS4777.2:2015 profile allows voltages up to 265v (for short periods, and shuts down on 10 minute averages above 258v). Residential properties are unlikely to be allowed to use export limiting to install even larger inverters. Now, such a hybrid inverter, as I previously submitted as a post, as being needed, would have the capability of providing for up to 10kW of panels generating capacity, and, of power conversion of up to 10kW, to provide for up to 5kW to provide for charging a battery system, and, the other 5kW to provide for the household load and with surplus (to the household load, out of the 5kW provision) being exported to the grid. We installed 4.5kw with a 5kw inverter in 2014. Single-phase properties can have up to 5 kilowatts of inverter capacity, and 3 phase properties can have up to 30 kilowatts. Technically, what will happen is the inverter will reduce the solar systems output so the generation will be forgone, but I dont want to go into too much detail in this article. 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 . Youll also start receiving the SolarQuotes weekly newsletter, keeping you up to date on all the latest developments on Australias solar scene. Powercor is the Distributed Network Service Provider for central and western Victoria, as well as Melbournes western suburbs. With permission export limiting can be used to install larger systems. 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. Solar Export Limiting Explained -- What It Is & Why It's Useful Hi Everyone, 0000038218 00000 n Why on earth would I do that if I can help it. Its also unusual for a large solar system to have all the panels facing the same direction. 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. How is export limited for micro-inverters? Off the main grid, rural properties can have 3 kilowatts of inverter capacity. You could buy a battery, charge it on the weekend and export during week nights.
