I have a small boat with 3 small permanent panels 2 x 20w & 1 x 40w, so 80 total, when on board I also plug in and additional 100w panel.
I believe they 'were' working OK, I have registered a max input of 5.1 amps, that was without the additional 100w panel plugged in.
Now it's warm and I have wanted to run a small fridge unit, I have been plugging in the larger 100w panel, but doing so initially made no little difference to the amps out.
I have tested the l00w panel and it seems to put out the expected voltage, but no amps.
Plus I no longer seem to be getting any amps form the other three units. The remote meter is not showing any input, plus I bought a clamp meter and that actually shows negative amps. I have tested the clamp meter on other appliances an seem to get a sensible reading so I have some faith that it's reading is correct.
The 4 12v panels are wired to a junction box with just one cable going on to the regulator.
I have some pics here if it helps - http://www.westerly-centaur.co.uk/so...and-smartguage
Any ideas what could be wrong?
