I've had my system up and running (sort of) for months now, but I've got a problem i can't figure out. My panels (7,680w of LG 320w modules) are feeding the two Classic 150 charge controllers and 500ah of SOK LiFePo batts), are putting out their expected voltage and amps, per a complete check of individual panels the other day. For some reason the controllers are showing volts but not amps. I called Midnite Solar and they walked me through some troubleshooting steps, but no luck. So they had me send them back to them for testing, and they came back good. I've been told that there may be a short circuit or misconfiguration of the wiring. After I checked all the panels the other day with my Fluke 115 multimeter, I jumped down to the combiner box to check voltage and amps there, but when I touched the leads to the individual incoming series connections, the multimeter lead for the hot side would arc at every one of the connections. I;m running 3 panels in series, with four series parallelling in the combiner box. This arcing was at the input side of each breaker. And this happened at both arrays (two arrays with 12 panels each). I have the 4 series wires run in leak-tite 3/4" conduit from the top of the pole to the combiner. Anybody have any idea how to possibly troubleshoot this?
The inverters (Trace SW5548's) and charge controllers seem to be working fine, and the batteries are holding 53 to 56 volts, depending on the day, and are all staying withing 1- 1.5 volts of each other. This is an off grid system that will be our power after we build a house on the 43 acres there. Since the charge controllers have tested good, I'm now trying to find where the problem is hidden. Anybody had this problem, or have an idea of where to start looking? Thanks for any and all suggestions or ideas. Lee
