Hello,
I am new to the group (and to solar) and I just purchased a DC Solar trailer at auction. The setup consists of 2 SMA Sunny Island Inverters, a Midnite Classic 250, 2 Industrial size FLA batteries, and 10 solar panels all mounted on a trailer. I managed to get the batteries charged up by hooking up a generator to the SI. All seem ok except that I can't get the Midnite Classic (CC) to charge the batteries. All connections are good; I also tested and measured the voltage and current of the panels to the PV combiner box. The problem is that the CC clicks periodically and switches back and forth between mppt bulk and resting but produces 0 watts. The CC displays the correct voltage, but is not pulling any amps to charge the batteries. Do I have a broken CC or am I missing something? Any suggestions of tips would be appreciated.
