So if the battery current limit is 20 amps, and there are two batteries in parallel, the inverter must provide 40 amps (20A x 2 batteries). This is not the case if the battery bank is configured in a series, because all the batteries have a similar current. Connect Batteries in a Series.
For example, running a 600w load for 1 hour requires 600 watt-hours (Wh). Using a 12V battery: Therefore, a 12V 100Ah battery would provide approximately 2 hours of runtime at full load. Deep Cycle Batteries: Designed for regular deep discharges, ideal for inverters.
As a rule of thumb, the minimum required battery capacity for a 12-volt system is around 20 % of the inverter capacity. For 24-volt inverters, it is 10 %. The battery capacity for a 12-volt Mass Sine 12/1200, for instance, is 240 Ah, while a 24-volt Mass Sine 24/1500 inverter would require at least 150 Ah.
Interpreting Results: Once you input the required data, the calculator will generate the recommended battery size in ampere-hours (Ah). For instance, if your power consumption is 500 watts, the usage time is 4 hours, and the inverter efficiency is 90%, the calculator might suggest a battery size of approximately 222 Ah.
