Laundry day is easier when you do not need the generator. Can solar handle a washing machine? Yes, with the right size.

Two kinds of power use

  1. The motor turns the drum. About 300W to 500W.
  2. The heater warms the water. Can be 2,000W or more.

Most homes in Port Harcourt wash with cold water. That makes it easy on solar.

Frequently asked questions

Can a 3kVA inverter run a washing machine?

Often yes for a cold wash with few other loads on. Hot washes and big front-loaders are better on 5kVA.

How much power does a washing machine use per wash?

A cold wash often uses about 0.3 to 0.6kWh. A hot wash can use 1 to 2kWh because of the heater.

Why does my washing machine trip the inverter?

The motor start or the water heater can exceed the inverter's limit, especially with other loads on. Switch off other heavy items or use cold wash.
