In summary, a single 12-volt battery can run a 1000-watt inverter, but how long it lasts depends heavily on the battery’s capacity, health, and the inverter’s efficiency. A high-capacity battery like a 100Ah AGM or Lithium-Ion battery can power your inverter for about an hour or slightly more under ideal conditions.
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.
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.
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. Always check the battery’s max discharge rate (C-rate) to avoid exceeding safe limits. When sizing for 24V or 48V systems, recalculate using the higher voltage.
