Hello,
At this moment I have a single phase connection and a single MP-II as ESS. No Out-1 or Out-2 connected.
Due to an EV-car, the main connection will be upgraded to three phase.
I will keep the single MP-II on phase L1.
To prepare everything for the upgrade, I have converted the electrical panel to three phase with an VM-3P75CT as energy meter.
At this moment, to keep everything working in house, all phases of the electrical panel are connected to the single incoming phase L1.
Question:
Before powering up the VM-3P75CT and MP-II, is it allowed that L1, L2 and L3 are bonded together to have the MP-II working before the upgrade?
Are there special settings to the VM-3P75CT to make to have the MP-II working on the temporary single phase situation?
