In the Victron app I sometimes get -6W or so coming FROM the AC out1 (going into batteries) when no load is connected the the output. Tried with both the Multi grounded and ungrounded, this didn’t make any difference. It also didn’t make any difference when I switched of the breakers that the AC out is connected to (so I don't understand where this 6W was coming from).
I borrowed a generator to test the AC input going into the inverter. The (old) generator outputted 190V and 57hz according to the Victron app. No current were flowing into the batteries. Was this probably because of the incorrect hz? The app settings says low voltage cut of 180V and start at 187V, so 190V should be enough according to that setting.
I managed to get it to take in some current by disabling ground checks etc. Then I saw 150W coming from the AC input, but also 150W going out from the inverter AC out even when the inverter function was turned off (set to charger only) - these input and output numbers were 100% following each other. I turned it off quickly as I thought it must be bad to have 150W “disappear” somewhere. How can there be power out from AC (inverter) when the inverter is turned off?
