I don't think the multiplus measures the AC output correctly, its just a calculation estimated. If you want accuracy , fit a AC sensor on the output, then select in the GX to use the sensor rather than VE bus data for AC out.
On my previous snap shot post, it shows 16w load, but nothing is...
The one I installed in March it’s been good so far, UK supplied 200A V3 with active balancer, yes the balancer gets triggered by the settings in the bms, in the same time with the resistor bms balancer.
The only hiccup I had was the initial comms to PC. With the right cable connects to BMS...
The generator startup will work, I adopted a different technique, ignore AC, then a flag assistant to call the grid on certain conditions to assist the loads.
Adam De Lay’s has this documented in his videos as well.
Best way is to find the D+ life signal, then connect that to H terminal. On smart alternators you have a simulated D+, but on older alternators it’s a true D+. Only comes on after you started the engine.

As above if you kindly confirm your supplier would be great, I also have one of those latest V3 and ready to be put in service. Problem is, I’m helping a friend out and he’s not knowledgeable enough to disconnect it if necessary. Mine came from Fogstar as a kit, hope they don’t have...
Here is mine in the van, with identical 2kva/ 12v inverter, idling. The only difference is the output is 230v mono phase. The DC load supplies a LTE router, and a motion triggered camera. Router is 24/7 on, camera is on stand by.
I also see a sub 80% efficiency with 1400w AC load, a small...
To be honest, all this answers are in the multiplus manual, including the ground relay for RCD operation and chassis ground. Yes you should ground the inverter to the chassis, and ALL metal appliances that are powered. But as I said, you have to activate the ground relay in VE config for stand...
I had AC coupled off grid with mppt’s as well. In my case, I had a multi 5kva, a fronius TL3kw, one 150/85 Victron mppt, and one 150/35. I hated it. Even being a hybrid AC/ DC coupled, the AC side was tripping if not enough load to keep the fronius going. As it’s on 53hz (Europe grid), the...
Swap your inverters on the outside ends of the bus bar, and the batteries in the middle, also make sure lugs touch the bus bar all the same.
I had in the past put a washer by mistake under the lug, and that battery was lagging 5A on a 40A total load of two batteries. Be meticulous and eliminate...
