Motors typically require 3 to 6 times their running current when starting. Check the manufacturer’s data
sheets for their starting current requirements. If you will be starting large motors from the inverter, increase
the battery bank size to allow for the higher start-up current.
4.2.4 Battery Configurations
The battery bank must be wired to match the inverter’s DC input voltage specifications (12 or 24 or 48Vdc).
In addition, the batteries can be wired to provide additional run time.
Series：Wiring batteries in series increases the total bank output voltage. This voltage MUST match the DC
requirements of the inverter or inverter and/or battery damage may occur.
Parallel：Wiring the batteries in parallel increases the total run time the batteries can operate the AC loads.
The more batteries connected in parallel the longer the loads can be powered from the inverter.
Series-Parallel：Series-parallel configurations increase both the battery voltage (to match the inverter’s DC
requirements) and run-time for operating the AC loads. This voltage must match the DC requirements of the
inverter.
Batteries with more than two or three series strings in parallel often exhibit poor performance characteristics
and shortened life.
