Select your country/region. In future, will powercor allow export limit if they upgrade transformer? This applies to both single-phase and three-phase properties. If your pumping needs are large enough this can pay for itself, but it will be expensive to set up. 0000037952 00000 n Origin offers 8 cents per kWh until a daily export limit of 14 kWh is reached. Allows installation but has an export limit. Although my testing shows that the micros technically operate quite independently, it is important to understand, only the Envoy can provide some critical components to a properly working Enphase System. JackD 1 year ago. Also note that for new installations in WA, only residences with inverters of 5 kilowatts or less can receive the states, Western Australias Western Power area: Perth and South West WA. As a side issue for you, if you (like lots of people) have high voltages issue causing shutdown / throttling, I am not a big fan of the Volt-watt modes, as often these modes will also lower the voltages at which the throttling kicks in. Is this default, or would it be programmed in if the distributor required it? More information about the program and how customers can get the most out of their rooftop solar is available at www.powercor.com.au/solar-energy you aren't allowed to export any power from your solar system to the grid. 0000037419 00000 n But youll need to be confident you wont be hit with high demand charges during the evening peak that will wipe out any advantage. (We are conected to a 25Kw transformer, with 5 consumers connected.). you request 5kW and Powercor says you can only export 2.5kW) Set a 'zero export' limit - i.e. ACTs EvoEnergy Network Area: Covers most homes in the ACT, especially in built-up areas. Im trying to get some unbiased advice on whether or not we should add more solar. 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. Of course, if you are planning to get an electric car, that has the potential to make a huge difference to your self consumption of solar power. 0000004622 00000 n 0000039018 00000 n Because you dont see the rather obvious shutdowns (or see them less), you might not notice your solar might be throttled back on a regular basis. 0000038484 00000 n Only residential homes with inverters of 5 kilowatts or less can receive the states. SAPN has told me I cant have more than a 5 kw inverter , but thats just not enough. Queenslands Ergon network area: All of Queensland on the main grid outside of South East Queensland. House batteries should have the capability of being set to turn off when they are fully charged and then on towards the middle of the day. 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? I believe it must have been set up during installation, but the installer company claims that this is handled by Growatt themselves. 0000018244 00000 n reliable export limit control function as per AS4777.2 to limit the export output where the . So the size of the system becomes irrelevant if you can only export 3kwh (we are Regional NSW Essential Energy). Long term benefits would be a more energy efficient system. 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. Am planning to install solar 6.6 kWh system and upon checking with powercor they are giving export limit as 0 kWh. If you can export 3kva that means you can have a solar system with up to 4 kilowatts of panels. 240 After a major works program involving more than 500 different network alterations and other activities across nine key regions among the most constrained parts of the network, Powercor's new solar connections export approval rate of just over 60% at the start of the year has increased to above 90%. 00@ Oo But if you suddenly switch off everything, there is more surplus solar power than youre allowed to export. 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. This gives the advantage of having a new system covered by a new set of warranties. Plus a Tesla Powerwall 2. Despite the low feed-in tariff you will receive it can still be worthwhile, especially if you can shift some electricity consumption to the middle of the day. Max. 0000001916 00000 n I am surprised to hear that Powercor has allowed you to increase your exports, but that is good to hear. 0000000016 00000 n That would provide both export limiting, and, the incorporation of a battery system (for my household, if we would have a 6.6 kW panels generating capacity system, rather than the 5kW one that we have, something like the BYD LVS 20 or 24kWh battery tower, would, I believe be appropriate), which would provide for energy arbitrage, smoothing both power exported to the grid, and, power imported from the grid, especially during peak demand periods. 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? The inverter reduces the amount of electrical energy supplied by the solar panels. See image at http://www.johnrogers.com.au/battery_charging_noon.jpg, CORRECTION: My 13.25 kW system will not go above the 10 kW inverter limit unless my house battery is charging and then it can go to 13.25 kW. That is correct. The data has 5KW flat lining confirming more is being generated. I think that the limiter can connect only to one inverter and not two at the same time. 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. Hi All. The battery is charging from the DC current which is before the inverter. Swearing revenge, he began his lifelong quest to reduce the harm the environment could cause. It also allows you to focus on increasing your self consumption which in turn provides a better return on investment. %%EOF Victorias CitiPower area: The Melbourne Central Business District. 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. 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. We respect your privacy and you can opt out from the newsletter at any time. so if I was correctly explained to, then I am limited to export less than 5kW (because my existing system will never produce 3.5kW), No installer (or their salepeople) is able to explain to me how the limiter is connected/set up in the scenario where I have 2 inverters. The majority of customers are approved for the export level they request. We have had solar for 6 years and just recently moved homes. Metered and a non metered version. Im surprised this hasnt hit the mainstream media yet. I think of it like the rate at which water is flowing out of a hose. Assume positive intention.4. The new inverter standard AS/NZS 4777.2:2020 has new inclusions to address grid stability issues - a new feature that is necessary to further enhance the hosting capacity to accommodate more solar and renewable energy systems. Victoria's "Hotest" Solar Postcode is 3977 at last look. Is this correct? I realise that Australian legislatures do not care about the future, but, the future is coming, whether the legislatures like it or not. An option is to take your pumps off-grid and run them independently off a separate off-grid solar system. If that is the case it seems counter intuitive to me as I dont know if demand will outstrip production until I actually turn the appliance (eg A/C) on and check the display. To me it does not quite make sense as no system can produce 100% of its capacity meaning my existing 3.5kW will never produce full 3.5kW (on a good day, I am lucky to get 2.5kW). Was sure if its been configured correctly or if this is just how it works? Is there anything that can be done about it? &K?BK:T$A1Cn I am afraid Western Power is very strict. When it comes to the limiting imposed by the electricity companies feed-in regulations, it means that, at any one time, not more than 5kW (100L) maybe be output to the grid (hose), it has nothing to do with the total over a certain period of time. Australian network service providers (including CitiPower) use solar export limits to keep voltage levels in transmission lines operating within safe . The standard relating to solar inverters is about to change. 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? When a home is exported limited, all the power the solar inverter can produce is available for the home to use. Powercor says the Solar Hotspots initiative is the first stage of a five-year Future Networks program to support customer investment in solar power systems, electric vehicles and battery storage. 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. 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. 100% You could buy a battery, charge it on the weekend and export during week nights. Fronius Wattpilot: A Smart EV Charger With A Short Warranty, You Wont Believe How Dumb The NSW Governments New Battery Calculator Is. I have 13.25 kW of panels with a 9.8 kW LG Chem battery and a 10 kW inverter export limited to 5 kW. On a related note, we mentioned yesterday that over the border in South Australia, SA Power Networks is readying to ramp up flexible solar exports in an effort to support more solar installations and its pretty clever stuff. 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/. 0000010603 00000 n 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? No unfortunately. ), converting to a maximum of 5kW of AC power, whilst the GW10K-MS provides for up to 13.5kW of panels generating capacity, across three MPPTs (strings? Real names are preferred - you should be happy to put your name to your comments.2. Im in regional WA with a rural 2 phase supply. Store it and use it later (this requires solar battery storage), or it disappears into thin air via a heat sink. just wondering if anybody can shed some light on the following, This profile also doesnt impose any export limits, because Endeavour Energy didnt require them of my installation (maximum is 30kW for a 3-phase installation, which my one is well under). 0000029403 00000 n 0000038296 00000 n 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. endstream endobj 351 0 obj <>/Filter/FlateDecode/Index[17 289]/Length 31/Size 306/Type/XRef/W[1 1 1]>>stream Yes I do have Enphase micro-inverters and an Envoy gateway, though not enough sunny roof to exceed 5kW, so my interest is rather academic but real. No matter how badly you may want to export limit your solar system, it can only be done in locations where its permitted. But just note, not everyone Envoy has required bits to do export limiting. 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.
