I am currently commissioning a Quattro 48/5000/70 single phase unit and a 280ah home made battery before moving everything to a cabin in the woods.
The only thing hooked into the L1 out are three recepticals with NO load and a lightning arrestor (which was removed for testing purposes).
The draw only appears while charging battery with temporary AC power I have wired in from my main service panel.
I dropped the charge rate from 21A to 15A and the AC load dropped to around 86W, kind of proportional. Is this what is consumed by the conversion of AC to DC?
Any thoughts on this?
