electrical questions.

I don't think this is particularly expensive. Do a Google for 'caravan supplies' or summat similar.

Yes, but they get bigger and more expensive as you up the ante. They also kick out a fair bit of heat themselves I think. Martyn may have more experience of this than I do.

Maplin stock them, as do Machine Mart, so you should get specs from either site. A 12V coffee maker would be cheaper!

900W at 12V is about 100 amps, give or take (accounting for some losses in the inverter as well). So you'll use about a quarter of the battery (very rough calculations, YMMV).

Mark - search maplin.co.uk for 'split charge'. They do a single module for £8.

Cheers

yes, but probably cheaper to buy a 12v coffee maker

The link didn't work but I like the website, My wife is gonna hate you for this, I'm going to buy all kinds of stuff from here.

didn't work when I clicked it either! but it's whats in the address bar of I Exploder when I go to the inverters page

anyway coffee machines are 25-50 squid - inverters are £200-£500+ for

900 watts +

It's an ASP site (badly error trapped and running an MS Access database at a guess). So the required data isn't in the URL.

Go to the site and search for "coffee maker".

Generally available - but not cheap - although that depends on what you call cheap.

Yes - but a new 12 coffee maker would be a LOT cheaper - and smaller.

The capacity is enough - but the maximum advisable current from the battery is probably not, depending on the type of battery. A 900w inverter will draw something close to 100A, but if it is a deep cycle battery this is probably about five times the maximum current draw for long life. A starting type of battery would be OK, but the depth of discharge will be getting rather high for one of these. JD

Any auto-electrical place will have them.

For question 1, speak to this guy, he supplied me with a very good voltage sensitive relay for just this purpose. Not too expensive either!
