Now this is getting wierd. I have been real busy with work and blowing the clutch up in my troll I didn't have time to post the panels back. So i get home a little earlier today, the sun was out, 27c outside, not a cloud in the sky and I though to sit outside with a beer, and package up the panel. But then I thought to give it one more shot with a 4AH 12V battery. To my surprise the charge light came on for the very first time since I purchased them, and it was charging at around 17Volts! Whereas before the charge light never came on and the highest reading I could get was around 3V.
Plus, whilst off the battery I checked the voltage output with my DMM and it was reading around 27Volts.!!!
So this regulator thats on it must auto switch or something. I was under the impression that this system I had will not work at all on a 12V battery...
I'm so confused now.
- before it wasn't working now it is...
And- The regulator I thought would only work with a 2 x 12V setup is working on a single 12V battery.
When I get back from holidays I'm gonna have to sit down and nut this out. Find out why it's now working, so then I am comfortable in selling it.
I have the Steca controller sitting on the shelf too...
