I'm installing a MultiPlus 12/3000/120 in my RV trailer.
I'm testing as I connect things - the first test after wiring up the fuse and battery disconnect is to be sure that it's inverting and making 120 VAC. But no 120 VAC present at the AC1 terminals.
I have the MK3 USB adapter and tried to download VEConfigure, but what I got was Victron Connect. It seems to be working and allowed me to update to the latest firmware though.
Victron Connect does say that the inverter is inverting. I don't have any power going in the AC In terminals yet.
I don't have AES on. Should I see 120 VAC on the AC1 terminals or do they need to see a load?
