Inverters?

Tomgunn
Happy Easter to all! ?


My friend's escaped Ewell, due to where we are today, and staying on his narrow boat he's owned for decades and is spending most of his time, apart from the beer, doing lot's of repairs.


Now, what's missing from his ship is... a washing machine. The thing is, the power supply, to that area of narrow boat ships', is somewhat low so, I suggested about an 'inverter'. He said that some of those ships have installed 'inverters' BUT, they have to have lot's of heavy duty batteries.


Can an inverter be run off of the mains'?  I guess that that may be a stupid question as the inverters' that I have run off of my car battery supplying 240v so, I KNOW how amazing you lot are and the wealth, (grovel, grovel), of information is unrivaled! 


So... he want's a 3K washing machine... can an inverter be worked, without lot's of batteries, to run this?


Thanks...


regards too, Tom

    If a mains supply is available that can supply 3Kw, then a standard washing machine may be connected to this supply. If the available supply is only just sufficient for the washing machine, then care must be taken to limit other loads until the wash cycle is completed.


    If no mains supply is available, or if the mains supply is not sufficient, then an inverter powered by batteries will be needed to work a standard washing machine. I would select at least a 5Kw inverter since washing machines are a challenging load. You may need to connect a lamp or other small and continual load in parallel with the washing machine to stop the inverter from going to sleep when the wash cycle pauses.

    Make certain that the battery is big enough. 3Kw at 12 volts is about 300 amps !


    Alternatively, look for a low powered washing machine, these have no heater and a reduced spin speed, some are directly 12 volt powered.
