Powering our Microwave - Page 2

Thepips · 01-09-2008, 06:51 PM

Our RV does have a 3kw inverter and 4 6v 125 amp hour batteries. The inverter/charger is mounted right next to the batteries with cables the size of starter cables. I have used the microwave off it, 5 minutes of microwave power doesn't hurt the batteries but I wouldn't want to cook a meal

Regards
Doug

For example 720 Watt is 60 amps - no standard motorhome wiring can get anywhere near 60 amps. Most circuits have a maximum of 25 amps or much less.

You need a very serious 12V power supply and non-240V charging system to provide such power.

For standard MHs microwaves are a no-no without 240V ehu.

the one i was looking at was only 124w...
you'de forget what you were cooking before it was cooked..

Up to now we haven't had any problems because we've only been to sites with hook-ups but what should we do when we start going 'wild'?

buy a generator.....no more worries

I'd go with Pappajohn on this. A generator of a suitable output will probably cost you half as much as an inverter and some are quiet and resonably light. If you're not bothered about the noise you can get a cheap generator for £90 whereas a 1300w inverter will set you back £400-£500. The inverter isn't weightless either and if you need an extra battery or two will outweigh the generator.

Good grief!

A genny or inverter plus 12V microwave - what a cost.

it's much cheaper to eat out at the Ritz.

Or failing that its even cheaper to stay on a site with an ehu.
