Where on earth has that 2 years vanished?
So coming up on the 2 year installation of the inverter and single module battery, and as with most things these days, the gradual improvements to firmware over time have made a huge difference.
So at the last update I'd managed to get the power leakage down through an offset, and the whole system was a lot more accurate, but nonetheless still had a small amount of leakage throughout the day which was averaging around 0.5-0.6kWh,
As promised another update, following many tweaks and a firmware upgrade from Solis.
So the existing problems were:
Whenever the battery isn't at 100% SOC, it pulls an amount of power from the grid, somewhere between 60W and 100W
Even when the battery is actively charging, it still pulls the same 60-100W from the grid, regardless if there is enough PV power to charge the battery and cover loads at the same time. Once the battery is 100% SOC and im generating PV
As promised a little update on the Battery Storage. Firstly i'm very glad I bought when I did, as everything battery storage wise has skyrocketed in price since, even the prospect of adding a US2000C seems unlikely for now, though to be honest, going on my usage I don't think it would add a great deal of benefit.
So I'm running the Solis 5th Generation AC Coupled Inverter, which does have a couple of niggles, which at present are reducing its savings potential. Those issues are:
