The battery-bank must be wired to match the inverter's DC input voltage
specifications (12 Vdc). In addition, the batteries can be wired to provide
additional run time. The various wiring configurations are as follows.
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.
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" configurations increase both the battery voltage (to match the
inverter's DC requirements) and run-time for operating the AC loads.
