I currently have 3x MP ii in parallel, running well in ESS configuration no issues and very happy I chose Victron except after a year I realised the efficiency is not as expected and trying to improve.
I’ve seen multiple posts and read manuals but can’t satisfy my knowledge on what would be the best approach to this particular scenario.
For low demand times I want to implement a small 500VA multiplus and turn off the bigger inverters, connected to the same 40kWh battery
One approach I know would work would be to double all components: Modbus meter, smart shunt, GX device, this wouldn’t be worth the effort
What I’m hoping is to be able to tap in the Cerbo somehow to share the existing data available for the small inverter to keep the ESS grid set point at 0W.
I’ll have to use only the AC IN terminals on both inverter systems for this set up
It’s almost like I would need a transfer switch on the VE bus.
Any suggestions much appreciated
