Does the Mass Combi work with washing machines?
The Mass Combi can easily power a washing machine. One whole washing cycle will, on average, take 80-100 Ah (with a 12V system) or 40-50 Ah (with a 24V system). Most of the energy is used to heat up the water, so consumption is properly correlated to the water temperature. Doing your laundry will put considerable strain on your battery for a short period of time, so it is important that battery capacity be sufficient: 600 Ah should be adequate for a 12V system and 300 Ah for a 24V one.
