Hi,
I am planning on going Solar in 2 phases.
Phase 1: Add battery backup (48V, 44kWh LifePO4+Seplos BMS modules), Inverter/Charger and power a critical load subpanel.
Phase 2: Add solar (7-10kW) + MPPT controller(s).
Option 1/Phase 1: I would like the inverter to prioritize grid for powering the subpanel and keeping batteries charged/balanced. Then have the inverter auto-transfer to batteries+inverter during an outage. I am confused as to whether I can set this up in the US/California (PG&E). Does this setup require a grid code? I am not planning on Net Metering or feeding back to the grid.
Option 2/Phase 1: Run the critical loads off of battery and use the inverter to keep the batteries charged. I am not sure what the pros/cons are of the 2 solutions.
I was planning on buying 2 Victron 48V 5kW inverters. But they are not UL-certified and I am confused as to whether I can set them up to handle Option 1
If I do require a UL-certified to support Option 1, what are my options for inverter/charger? I assume that the main choice would be a Sol-Ark 12k?
Thanks for the help!
