yesterday I had closed loop and for some reason it went up and down 5 times from 55.6 to 53.9 v. I decided to go back to Lead Acid settings and it didn't act so good because it went down to float but then started climbing again to absorb. I shut off the pv inputs because I can divert them to direct pv loads. After both of those were off the inverter started giving me faults and shutting off and restarting the 240v inverter for no apparent good reason. The fault code was E019 Bus voltage too high which is weird since there was no pv going into it at the time. I shut everything down and restarted and it seems to be goign okay now. I reprogam via computer Maintenance screen. When I have done that I also notice that when I make changes to pv charge settings it will shut down the inverter. This has me wondering if the whole unit needs to be shut down and restarted after making any changes. I do have a different charge controller on the same battery but I look at those and they will drop down as programmed to their float value - it is only the 6000XP that acts odd. At first I did still have the closed loop cable still plugged in when I changed it to Lead Acid mode but that shouldn't make any difference - does seem like it since it was not displaying the bms SOC. Seems like maybe this inverter is geared more towards having AC input in it than being strictly off grid capable. The firmware really seems to act strange with just PV input and using the inverter.
