Howdy solar gurus. I seem to be having a problem with my system shooting out a surge of high voltage every 30 seconds or so when the system is simultaneously charging and also powering its little area of the house.
This causes the inverter to shut off and the power to cut off and on in a loop until I go downstairs and just switch everything back over to the grid. It ONLY happens during the day when the battery is receiving a charge and simultaneously trying to provide power. At night this is not an issue. I plugged in a 1500w vacuum cleaner (Inverter is 3000w) just to see if it would correct the problem, and it did, but obviously I don't want to keep a continuous high draw on the system just to catch the spike.
I actually have 3 identical systems running, so I was able to swap out charge controllers, batteries, inverters, and transfer switches, and believe I have isolated it down to this one battery. Transfer switch points are 51.2 and 54.4. Charge controller is set to charge the batteries to 56.1. I have played with all those numbers a little bit but nothing seems to fix the problem. So that's what's going on...it seems to be that this one battery does not like to charge and provide power at the same time. The other 2 systems have the same settings and no problems. Is there a fix for this? Any help is greatly appreciated!
