I got the bleeping 65 error when I got up this morning, everything was working great yesterday. Today it’s faulting my solar panels, which still do bring in a little sun with snow on the horizon. Yet the alarm is going off. No combination of panels works, I have 24 100 watt panels some on expensive sun tracking arrays. I am beginning to think it’s a faulty cord now. or faulty setting in unit. It’s the AC300 and I recently added another b300k.
thoughts?
Hi @DragonbloggerSheilaB, Could you provide more information about the solar panel arrays connected to the two input ports (PV1/PV2) of your AC300?
Please note that the “PV Parallel Enable” should only be turned on if both ports connected to the same arrays solar panels that have a combined power greater than 1200W and an open-circuit voltage of less than 150V. If this is not the case, you should turn off this function.
Please let us know if it works.
