Check

Can the battery's BMS feed my inverter?

Only if the inverter's full-load DC current is within the bank's BMS continuous rating. We work it out as continuous watts ÷ the maker's peak efficiency ÷ 12 V calculated, then compare it with each of 12 batteries. Data updated .

How the check works

Draw at or under 80% of the BMS rating: works; between that and the rating: works, tight; above it: no. Batteries in parallel add their ratings. If the maker publishes no efficiency we use 88% [house assumption]. The surge check compares surge watts the same way with the BMS peak rating.
