Dead Battery My inverter did not charge batteries when batteries reached 49 Volts, which was setting in program 12 on inverter. First battery from inverter was completely dead, and 2nd battery was at 8% charge. I then set program 12 on inverter to 50 Volts, and 2nd battery started to charge. But 1st battery from inverter remained off and not charging. I have a fully 100% charged 2nd battery from inverter, while first battery is dead. I have turned on and off the breaker and on button many times. I have also pressed the reset button for over 10 seconds many times, and still have a dead 1st battery. What do I need to do for inverter to start charging 1st battery?

I just received a 2nd 5kw op battery, and I would like to verify how to connect this correctly with my master battery without a bus bar. Can I use the 2nd battery connection terminals from my master battery to my new 2nd battery, or do I need to connect the cables going to my 2nd battery to the same connections on the master battery? Any other information on communication between batteries and OP inverter also would be helpful.

I've had my 48 V opsolar battery and 6.5kw inverter for less than a year. I also have a 2KW off grid solar panel set up with this system. Until today I was producing circa 1500 watts an hour when the sun was up, which would charge my battery and other loads. Today when I went to check on my system at around noon in full sun, I noticed my inverter only producing about 100 Watts on each of the two MPPT strings (200 watts total) to charge my battery, and my battery would not get above a 40% charge level. When I put another load on, the inverter then quickly went up in production to about 1300 watts, but my battery still did not charge beyond 40% with the inverter. Anyone have any clues for this, and how to rectify the situation? Another thing I noticed is that despite my turning the battery off and the inverter off, the inverter stayed on until the sun disappeared. Is my inverter supposed to stay on with the sun up, and the power button turned off? When the solar power to the inverter finally stopped and the inverter turned off, the inverter started a nonstop clicking noise. For fear of damaging the inverter, I turned the battery and inverter back on to stop the clicking noise.
