Solar charging

[mudski]

This is the exact panels I bought : http://www.ebay.com.au/itm/NEW-GP-12...item3f1d8b6c94
I want to find out whether they are working properly or not before I try to flog them off as I really don't think they are working correctly.

Regards the Charge LED I'd suggest depending on the order you disconnected the equipment that there is enough capacitance to hold a charge sufficient to light the LED for a period of time

Understood but strange as the charge light doesn't come on when I have everything connected and the panels basking in the in the sun.

Regards the Load LED I'd suggest it is illuminated because you are below the low voltage cut off when the Reg is in 24 Volt mode

I have tried connecting to many different batteries, even my aux battery which was at 12.4v.
If these are faulty which I suspect they are, I want to return them before the warranty runs out. I don't want to sell something that I'm not sure works. The first time I used them, last Easter weekend, 4 sunny days we had. I had the panels on the whole time and the whole time there the charge light never came on and I ended up with a flat battery. Putting it down to my inexperience I just thought my fridge, 32L Engel, was using more power than the panels could produce.

Because I have never heard of 24v folding panels before I would advise you to check the open circuit voltage of the panels in case they have been mis-labelled. Put them in the sun, put the multimeter onto volts & put one probe on each output cable. If they are 12 v panels you should get a reading of up to about 18v. If they are 24v you should get a reading of up to about 31v.

Find this out first & we then we can take it from there.

I did this and the best I could get was no higher than 3v. Yes, 3 Volts.
