Thanks for all the suggestions. I'm in a really remote area so dont have a lot of choice unfortunately.

I ended up getting the 4 Trojan T105's, they're so common they're cheaper than anything else comparable. I always treat my batteries really well so...

Looking good.... now with just off the shelf components, we can finally make a real inverter..... that  is easy to fix as well... utopia indeed for remote living I don't think any other unit on the market can say that.... usually you have to replace pr...

Okay, On /Off is operated by allowing the voltage to rise to above 4.3v, ie, 5v by closing the circuit and Pin 15 on the 8010 HT1536 chip sees this as an over temp and shuts down gently.?

Hello all, I am looking to add a heat dump to my domestic SHW system. I am looking for a non electric valve that has a thermostat in it... so that when the temp of the loop hits a certain level, the valve allows the heated glycol to run through a radia...

You're right (of course) Oz.  It's been a while since I worked on these so that distinction wasn't clear.

 i like  the use of that "special'' blade ,  it allows the oscillating water movement to become a constant rotating motion.

you need to design something like a bellows on the dock tha...

I don't want to use a heavy float because I then have to build a heavy float, and it needs space. Boats already exist, so it's a kind of parasite generator.
