Q & A

maximum voltage of appliances

What max wattage vacuum cleaner can I use with my inverter which is 1600va, 70amp? Our 1000w one is on its last legs and I can't find a similar low wattage one.

A difficult question to answer; since some inverters quote a maximum "start up" current, and others the constant supply current. So the 1600VA means that it could supply 1600W for a resistive load such as a heater, either for a short "start up" period or continuously.
A fair estimate given that it is happy driving a 1000W vacuum at present, would be a maximum appliance load of 1300W (1.3kW). Anything higher than this could overload the inverter, and the appliance will not work properly.

If I'm using my Dyson DC07 vacuum here aboard ship then I make sure that all other appliances (eg kettle) are switched off for the 5-10 mins it takes to vacuum up.
