Configuration boundary

The current V1.4 datasheet lists HVS, HVM, HVB, HVM+ and HVS+, but different battery models must not be mixed. Parallel towers require the same module quantity and matched state of charge at installation. The exact inverter list, tower current, conductor sizing, protection and warranty must be checked for every project.
