Looking for some advice. I just installed a Victron Energy SmartSolar 150/60 PV charger on my boat. My battery bank is 6 x 100AH 12v LiFePO4 batteries in parallel (12v system). I have 6 x 100watt topsolar flexible solar panels on the hardtop of my boat. I have them installed in two parallel strings of 3 panels in series (68v per string, ~6 amps per string). So i theoretically should see 68v, 12Amp and 600watt maximum at the solar charger input. My Victron SmartSolar charger reads 68v but 0 amps and 4 watts output. I am only getting 3-5 watts in full sun with the batteries at 50% discharge. I have the Smart Solar charger set for 12v LiFePO battery setting. Set the bulk charge rate to 14.4v per the battery manufacturer settings. Could this be a solar charger settings issue? What can i do to troubleshoot this?
