Use +word1 +word2 to find all posts which include both word1 and word2.
Use +word1 +word2 -word3 to find all posts which include both word1 AND word2, but NOT word3.
Use "word1 word2" (with the double-quotes) to search for exact phrase.

Well, I went to Aire and Power yesterday to suss out what panel I actually had (see other post on this subject)
They are a small outfit but Steven/Stephen seems to be up on his subject.
I got some mounting brackets, Sikaflex and primer, and a roof mounting grommet thingy.
I didn't get the charge controller from him as obviously he has a vested interest in selling the ones he stocks.
So hopefully one of you peeps can reccomend what I need to get to suit my system, without breaking the bank.
I have a 40watt, 5amp panel, and I want to use it to recharge two 110ah wet batteries , so 220ah in all, now I know I'm not going to light up the planet with this set-up, but we don't need any more than this amount of power.
I'd like to also be able to keep the Engine battery from going flat.
So ladles and jellyspoons, what do you suggest I get.
I have used these ( link below ) alot and had no problems or failures to date. Can handle 20 amps with digital display reading. Also able to use the load to feed engine battery.
The using the load to charge the engine battery is a new one for me, as is most of this stuff, which is why I'm being so cautious, I was under the impression (rightly or wrongly) that to charge the engine battery, I needed a splitter or some such device, but I'm not sure where in the system this should be placed.
I got mine from sunshine solar (the yellow one depicted in the picture) cheap and cheerful, orange light when charging, green when fully charged.
Had it fitted for over a year now with out any problems.
I couldn't see a price or any details for the yellow one Charlie, but I did expect more of a response on this post , considering all the talk generally on this subject.
The eBay one you post looks ok but is a shunt regulator I prefer series regulators as they take less power from your panel when the battery is fully charged however all the other parts of the spec look ok to me including the price.
(When the battery is fully charged a shunt regulator shorts the panel output to earth a series regulator stops current getting to the battery)
Its difficult to comment further without the detailled specification as the devil is often in the detail.

I am a little concerned that the final voltage is 13.7 I would expect 14.4 and that although they have quantified the negative temperature coefficient as -3mV/degree C they don't specify what temperature the 13.7V is quoted for. As I say Kev devil in the detail.
