Had a day today where the house load has been fairly low and the sun has shone meaning the battery has charged from flat (4%) to 100% with no discharge showing.
Total charge 8.1kWh. So I guess pretty much spot on. Given it’s a 100%Dod 8.2kWh battery.
Mines a bit hit and miss but I just need to get used to it. If I run it down slow I get the full 6.5 but if it happens to be pulling max load the voltage sag appears to take it offline early. It’ll then OCV and start back up again after 40mins. Whether the load is still there or not is the “hit and miss” part of this new style of operation. Luckily I have a second system that picks up the slack so not to bothered.
I am keen to see if the new degradation mapping stops this once I cross 1000 cycles. I’m not sure when the BMS moves to older and older curves/maps but 1000 is a nice round number so we’ll have to see.
