Solar & Inverter Aircon Compatibility

Estimate whether your solar inverter and battery bank can safely power your air conditioner, how long the battery will last, and how many units you can run.

Important disclaimer: Results are estimates only and do not replace assessment by a qualified electrician or solar installer. Actual performance depends on inverter brand, battery chemistry, cable sizing, ambient temperature and load profiles. Always consult a qualified professional before installing or modifying your electrical system.

Inverter Details

Inverter continuous rating (kW)

Inverter surge rating (kW) optional

Battery Details

Battery capacity (kWh)

Usable capacity (%)

Lithium: typically 80–90%. Lead acid: 50%.

Reserve % (keep above)

Load Details

Household base load (kW)

Lights, fridge, TV, router etc. while aircon runs.

Solar panel contribution (kW) optional

Air Conditioner

Aircon capacity (BTU/h)

Not sure? Use our BTU calculator first.

Number of units

Compressor type

Most modern splits are inverter units. Non-inverter compressors draw a much larger startup surge.

Running an aircon on solar depends on the inverter size, battery capacity and your other loads — always confirm with a qualified installer.
