5. LED OFF: no battery or over voltage.
1. Check wires
2. Reduce Amps if needed
3. Reset controller"
thanks!
Hi @leoncm
A complete power-down should suffice, on both the battery and solar sides. Leave it for a while, and reconnect it battery first.
Make sure too that your batt connections are solid. No alligator clamps or otherwise doubtful joins on the batt side.
thanks for the reply John!
so just to be clear, when you say a power down, i assume you mean physically disconnecting the connections at the charge controller? point taken to disconnect the solar first and then the battery and then reconnect the battery first. does it matter if the sun is on the solar panels when i do this? and ... which terminal should i disconnect first? pos or neg?
cheers!
Yeh, I meant physically disconnecting them, unless of course you have physical switches. It's likely enough to just isolate the positive wires and leave the negatives connected.
It won't matter if sun is on the panels (you have low V). And if you have a handy multimeter, an opportunity to check panel polarity (with the -ve disconnected in that case).
