They want to do it there way and it seems my request complicates things for them and I dont hear back, bar a couple. 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. What am I missing? Youre using a total of four kilowatts to cook your lunch, so your home is exporting 4 kilowatts, which is below the limit. 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. . 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. sonnenBatterie Evo. I could not convince him that I knew what I was talking about! 60% lagging But you probably would not recover the cost of the battery within its lifetime. The fact is that Powercor does not set an upper limit on the size solar panel system you can install, up to 30kW. What inverter do you have? I realise that all the political parties in the the WA state parliament and especially, the Synergy/Western Power conglomerate, that controls approvals of domestic rooftop photovoltaic systems connected to the SWIS grid, are opposed to domestic rooftop photovoltaic systems (even though we stabilise and sustain the grid), but, I am wondering whether any reason has ever been given by the oppressive authorities, for banning export limited inverters in WA. The ideal way to measure the power flow in and out of your house would be to ask your existing electricity meter. It owns and operates the states largest electricity distribution network, and is responsible for more than half a million poles and over 88,000 kilometres of powerlines. While there are some energy management measures that could help around the edges, I cant think of any good solutions for the typical business. Im on a swer line in rural south Australia. 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). This applies to both single-phase and three-phase properties. You could contact Powercor and explain your situation, but I suspect theyll say you need to be an installer to check if an increase in export capability is available. If you are in the solar industry - try to get to the truth, not the sale.5. So what goes throgh the meter, in either direction, is the difference between what you generate and what you use. Exporting surplus solar power is good because it reduces fossil fuel generation and pays you a feed-in tariff that reduces electricity bills. If they want a big solar system with an inverter larger than 5 kW, they must export limit the inverter. I cant see any reference to the NT. See image at http://www.johnrogers.com.au/battery_charging_noon.jpg. But just note, not everyone Envoy has required bits to do export limiting. Australian Rooftop Solar Powers Rise Astounding, But..

Please confirm the maximum export limit in the relevant section of this application.. And doing so potentially puts you running in a non compliant state. At the moment a battery system is unlikely to pay for itself, but you could install a system that is larger than what makes financial sense for your current situation and hope home batteries will fall in price over the next few years. This is done for three main reasons: In this article, Ill give a broad outline of how export limiting works and why it can be a good idea. If your pumping needs are large enough this can pay for itself, but it will be expensive to set up. Economically this probably Is not viable, as our electricity bill is fairly low. Max. Were continually investing in our networks and aim to keep customers informed if additional export capacity becomes available in their area. Sometimes Powercor can reduce that to a lower figure, or even set a zero-export limit. driving range of 200km depending on ambient temperature. It also allows you to focus on increasing your self consumption which in turn provides a better return on investment. While export limiting is possible its not always approved. 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? 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. There are versions without this consumption monitoring (old Non -s version of Envoy and even the Envoy-S without consumption monitoring). I am a total newbie to this but I am unclear why export limiting is good? 0000029011 00000 n Unfortunately, SAPN wont allow more than 5 kilowatts of inverter capacity on an SWER line. xref Thank you. Unfortunately, the inverters parameters such as Export Limitation are all password protected, and so far I have been unable to even determine who knows this password. hour of charging is enough to drive 35km.. An option is to take your pumps off-grid and run them independently off a separate off-grid solar system. But it seems the situation has been changing for the better in the last couple of months in a number of affected areas. Victorias Powercor area: Western Victoria, including a large portion of West Melbourne. I cant justify the cost of adding additional solar if the max I can export with Essential energy is 3kwh. PDF Origin Energy Electricity Limited Origin Solar Boost (TOU 5 Day with 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. Some say so you want to replace your system? Normally single phase properties can have up to 5 kilowatts of solar inverter capacity and 3 phase properties can have 15 kilowatts. 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. AC Output Data We might still be willing to do this all the same, from an environmental viewpoint. 0000037419 00000 n This is disappointing as this would be an easy option to implement. In writing I was advised: My solar installer applied to Powercor to install a 5.4kw system at my Point Cook address. Below is the email response I received from Powercor. ), 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? PDF Powercor, CitiPower & United Energy Im trying to get some unbiased advice on whether or not we should add more solar. At times MPPT1 is at 600 odd watts while MPPT2 is at 2500 odd watts. DC Input Power (Wp) 10000, from its published datasheet. So far I have not seen much more than 5kW DC anyway, but in summer I would expect to see a curve thats flattened at the top during the high sun phase, as it is cut off by the inverter. If that doesnt worry you then you can get a battery and just hope it mostly pays for itself. 0 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. My assumption is (and I may be wrong after all) that the idea of using my own energy first before buying from the grid is an illusion, and in fact it only appears like that because all the energy from the inverter (up to 5kW) is measured as exported, all energy required by the house is actually imported from the grid (as if there was no solar system at all), and it is just because the exports are offset against the imports for billing, why it appears that my PV system is reducing the imports. Upgrading the local electricity network so more businesses and households can export excess solar to share. "Some of these customers may have received approval to export since, due to network improvements made since their connection." 1. 240 Metered and a non metered version. 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. And yes 5kW export limit applies May I suggest an extra fact check to polish the valuable story above? Even then, the losses from the limit are minor. We installed 4.5kw with a 5kw inverter in 2014. it is, kind of, effectively export limiting. 0000000016 00000 n Its also worth taking a look in case you shied away from installing solar panels in the past because of the situation now might be the time to revisit the idea. To add to this, in the installer section of the Envoys web server control panel, you can set the profile by which all microinverters operate. Why my Power Limit is set to ON with the % whereas her Power Limit is set to OFF and she has been exporting. What is the go generally with adding an additional solar system to your home? They did say that with future upgrades we could reapply, but I cant find a way to do this. 0000010603 00000 n 0000039096 00000 n I am on my second Tesla EV and the new one has a rage of 700km if youre not a lead foot. Major upgrades supporting more solar exports for homes in Victoria's The solar PV system is connected to the network via an inverter. This extra meter adds to the cost of a solar system. Anyway you are probably not supposed to be messing around with the profiles without agreement of your DNSP. 3. at night or not enough at day time ? But whether or not extra solar capacity will pay for itself is another matter. So my understanding of the info above is that my inverter will increase production in unison with demand until it hits 5kw? Efficiency has and will improve further over time, but never to the point of perpetuity. A Decent Battery From sonnen. How is export limited for micro-inverters? Because people have been refused any STCs for being just a few watts over, no installer will go over the limit for a normal installation. 100 litres alone means little, but if there are 100 litres per hour, this means 100 litre hours of output. The Ugly: In these areas export limiting may not be allowed at all. If you cant store the power (too expensive) and you cant export it, why the requirement (or desire) to put in large systems? In contrast, most other network distributors set a strict upper limit on the size solar panel system you can install, typically 10kW for single-phase properties. Any ideas of how I can get a system that is actually going to generate enough power to charge a battery? I will update the article with the information. I also dont know if my meter has limiting but suspect not as it is a pretty dumb device. Voltage (V) measured at inverter terminals I guess it would be technically possible to have a solar system with a battery but still be connected to the grid as backup. Whats the logical and practical way forward? and only supply me with power from the grid 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? I was told to set Power Limit to ON. 0000008043 00000 n And, depending on the circumstances of each individual household, 10-15 kW of total panels generating capacity, with limiting export to the grid, to 5kW, could provide better for the months with less available solar radiation, to lessen the demand for grid electricity, peaking on a seasonal basis. Worried the impact this will have currently when we charge an EV in the near term. 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) ARTICLE WRITES: Queenslands Energex area: South East Queensland. If a home cant export any power at all then there is no financial reason to install a large solar system. %PDF-1.4 % If you are in the solar industry - try to get to the truth, not the sale.5. Was sure if its been configured correctly or if this is just how it works? Or is there a build up of voltage in the system? Finally! Am planning to install solar 6.6 kWh system and upon checking with powercor they are giving export limit as 0 kWh. We are on a zero limited export. Thanks Steve 0418 815 193. 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 majority of customers are approved for the export level they request. About 50%. 1. 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. NSWs Endeavour Energy area: Western Sydney. But I can tell you a few things that might help with some of your pondering :- 1. Export limiting does limit the inverter output, but only as needed to keep the export power below the limit. Sorry Andrew: NQR. 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. 0000093063 00000 n Victoria network plans upgrade to allow for more rooftop solar exports Is there anything that can be done about it? Powercor households stand to save even more with solar Youll also start receiving the SolarQuotes weekly newsletter, keeping you up to date on all the latest developments on Australias solar scene. Sorry if dumb question. I prefer a profile that just has the voltages set to a high voltage threshold, and if I have to sacrifice V-W mode, so be it. I think I was partially wrong about how my PV is connected to the home and the meter. If so, it would make replacing the whole system more viable which is exactly what I wanted to avoid (and such a waste!). 0000037497 00000 n Hello. hb```f``sd`c`edd@ A >hp`86s8::\ MNmOe0pYuR`i g G7@ $n@]A#&S_2.dx f My guess is that when the Envoy-S sees it needs to throttle due to export limits, it does this by sending the same instruction to all micros to throttle the same amount (but dont know for sure). 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. And Set Power Limit to 100%. 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, 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. Do the inverters prevent the production of energy by the solar panels when an export limit would otherwise be exceeded? 0000039018 00000 n Hi All, Thus if my system is at maximum output, and I am using 2kW, only 3 kW is being exported to the grid. Note that connections off the main grid are usually far more restricted. I think the installers like the Volt-watt modes, because if you dont know where to look they hid the problem at your expense anyway.
