No AC loads yet Quattro reports a 244W AC draw while charging?? Pic attached.

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? 105984-8fc1750ce4c7acbf0fd0e23894e38cb8.jpg

So you get 244W of "AC loads" with 2133W of charging.

When you got 84W of "AC loads," what was your charging power?

Was the inverter in "ON" or charger only mode?

Did you try it the other way and have the same results?

I believe it was set to 'charger' only. If I remember correctly it happens in the 'on' mode as well. I will confirm this when i get home later.

When I got 84W of AC load I was charging with 15A.

Bump. This is really strange. I checked my VRM for the last time I charged, and I showed no increase in AC output with about 1200W of AC charging.
