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.
Typically, a 12-volt car battery can support an inverter with a power range of about 150 watts to 1500 watts. Please note, however, that car batteries are not suitable for driving high power inverters for extended periods of time, which may cause damage to the battery.
Match the inverter’s continuous wattage rating to the battery’s discharge capacity. For a 12V 200Ah battery (2.4kWh), a 2000W inverter is ideal. Formula: Inverter Wattage ≤ (Battery Voltage × Ah Rating × 0.8). Factor in surge power needs but prioritize sustained loads.
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.
