I have been happy with the 400 watt system I set up on my boat, Renogy Rover 30 amp and the system has a 2500 watt Aims inverter and a 3000 watt generator for heavy load use. Its all connected to a bank of lead acid, two trojan 105 six volts and an 8D lead acid which is about 280 AH in parallel, then also a starting battery for the boat's engine. And I have a mechman alternator that puts out a nice charge at very low RPM and use this to charge the system in the early morning when its down to 11.8 or so from running refrigeration all night.
Its been great and I was able to operate my washing machine from the solar panel charge output which would vary from 9 or 10 up to 18 amps at times through the controller. And the batteries would charge to a nice 14.5 on a sunny day.
Now suddenly Im getting less than two amps and yet the panels still put out their rated voltage according to the volt meter. (Im not sure how to read the amp output) I did some heavy work with the generator going and the inverter going full blast, pressure washing my decks. There were likely power surges. Ive also had the inverter make a horrible jackhammer sound and go into error shutdown because of low battery. Then it comes back on after it cools and resets itself, and I find these Aims inverters are a bit sketchy and do not tolerate low voltage.
Ive been very careful to NEVER disconnect the batteries with the solar panels connected to the charger but seeing the current low output Im rather sure the controller is messed up. No error codes. Just next to nothing being sent to the batteries and the panels show just under 30V, two pair of 100amp Renogy panels connected in series, then into the controller through a combiner fitting.
Where did I mess up? (No fuses in the system, I really didnt see the need for them, other than a high amp battery cable protection fuse) Ive watched the controller floating around between one and 0 amps just seeming to not know what to do. Mostly just sits at zero now. 5PM and the sun is low but still very clear and bright. Panels still showing 25/30 volts.
Thanks in advance!
