I have an inverex veyron 5.2kw inverter (bought 6 years ago) and I'm using it with 4 phoenix t1800 lead acid batteries(2.2kw each) connected in series... The batteries are at the end of their life after 6 years... I have 10 solar panels (550w each) connected in two sets of series(5 each side) and there is no net metering cz i changed houses a year back... I was thinking instead of net billing should i just get a dyness powerbrick SC 16kwh and completely use that instead of the grid(unless necessary)... My daily usage is 10kw average with june and July sometimes reaching 17kw max in the day...
