I have recently bought and installed my first solar system. I have no on grid electricity and I live on a farm, so you can imagine my annoyance to come home at 5pm to empty batteries. I have started to notice that my Axpert King 5Kva drops the pv source (12x330W solar panels) and does not reconnect until I hard reset it(by disconnecting and reconnecting the battery packs). I am a novice in the field and would appreciate any help or suggestions to rectify the problem.
