Victron multiplus2 8 kw and 2 10 kwh dyness battery. Cerbo finds battery and battery dip.switches are correct. The issue I’m having is when a pump (1 kw ) or a floor grinder or skill saw starts up the inverter instantly goes into low battery and shut down. Cerbo will either turn off or stays on when the load starts. System works with a heat gun load no problems. When I try the same loads on my home system 4 kwh BYD and a 3 kw multiplus2 it operates them (a bit of a struggle to start with ) setting inside inverters are exactly the same and systems are dedicated off grid. Does anyone have any ideas what the issue could be.
One battery ia better than another?
Capacity isn’t a measure of performance.
No as it is happening on other systems with 1 battery
