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

    Clearly the way to operate from the mains is to have a hefty battery charger! I suggest that you will need about 5kWhr of batteries, probably operating at more than 12V because more volts gives better efficiency everywhere. Lorries often have a 24V one for the kettle and microwave, so the price is fairly low. 200 Ah of deep discharge batteries, a 30A charger and a 3kVA inverter should do it, along with a 24V alternator added to the engine should see you with a great system, perhaps even some solar panels on the roof to keep everything charged during the unused times should do it, perhaps £3k or so altogether if self installed. An excellent addition to any narrow boat, because you can then use mains voltage LED lighting and an electric fridge too.
