Re: First planned "event" for our VPP

Bud, Savings have been a little hard to calculate due to the supply charges increased and feed in decreased (24c to 16c) around the same time our original VPP was installed. What I can say is that our total consumption decreased by about half. We had an existing 5kw Solar array and the quarterly figures are as follows. We are a full electric house. I have not done the calculations of the decrease of solar feed in due to the PV charging the batteries. Aug 2016 2541kWh Aug 2018 162 ...

Re: Over Voltage on Grid

Hi Peter3991, We had an over voltage issue earlier this year which was caused by lots of solar production and low consumption in our local grid. This artificially raised the line voltage which caused our inverter and battery system to shut down until the voltage returned to tolerance.This happened over a mild spell of weather where there was a low usage of heating or cooling. It was solved by SAPN (SA distribution) switching us to a different phase from the mains which had ...

Re: VPP

Hi Bud, Since our installation last August we have had one event. We received notification on the Solar command website in the morning that we will be part of an "event" from between 4:30 and 5:30pm on the 19th of January. It read"This event may involve discharging some of the stored energy in your battery. Solar self-consumption will operate as usual at all other times"This is the first and only one since our installation in August last year.At 5pm that day, our VPP started exporting ...
