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.
However, you can determine how long will a 12 volt battery run an inverter depending on how many watts load and amp-hour the battery has. In general, a battery lasts about 10-17 hrs with a 12-volt battery inverter. Batteries work by creating current flow in a circuit through exchanging electrons in ionic chemical reactions.
For example: If you're running a 1500W inverter on your 12v battery with 1000 watts of total AC load. So your inverter will be consuming 83 amps (amps = watts/battery volts) from the battery for which you'll need a very thick cable. using a thin cable in this scenario can damage the inverter or you'll not be able to run your load.
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.
