Solar Inverter Size Calculator

Type your home or shop load and find the right inverter size (kW) — not too small, not too big.

How to use

1. Add all your appliances from the list (fan, fridge, AC etc.) — add anything not in the list as custom watts.
2. Select future expansion (25% is recommended so you have room to add load later).
3. Press "Calculate Inverter Size" — see the recommended inverter kW and category.

This is an estimate. Talk to your installer before the final selection — motor loads (pump, fridge compressor) have a higher starting surge.
