My setup is as follows
3 phase (L1, L2 and L3) electrical supply
Victron Multiplus II 5KVA connected to L1
4 x Pylon Tech 3500Kwh Batteries
18 Panels 355 Watts
At times the connected phase on L1 fails resulting in the battery running flat on cloudy days.
Is it possible to use either L2 or L3 as an alternate source for charging the batteries should L1 fail ?
My initial thinking is an additional regulator and a failover relay to switch the charging circuit on the victron from L1 to either L2 or L3... but open to more informed suggestions.
Thanks in advance
