I recently purchased (2) lv6548 units and (3) big battery 48 volt hsky's. I currently am only running 1 lv6548 and 1 battery as I am testing my setup.
I ran one battery (A) with the lv6548 and it will not charge the battery past 53.7 volts. I tried to charge battery (A) with a separate 58.8 volt 15 amp charger and it won't charge past 53.7 volts.
I charged battery (B) with the same charger and it charged to 56.2 volts.
I connected battery (B) to the lv6548 and ran it for a week and it will not charge the battery past 54.2 volts. The amperage is charging around 20 amps and at 54.2 volts it drops to around 10 amps and voltage drops to 53.9 volts. This continues throughout the day.
I cannot figure out what I am doing wrong. I have messed with the settings. and there are no changes. I finally just lowered setting 26 to 54 volts and setting 27 to 53.7 as I do not know what continuing to trying to charge this battery past 54.2 volts will do.
Settings:
1. sbu
5. use
12. 48v
13. 50
16.oso
26.58v
27 57v
PV array 6 panels 3s2p 171 volts. At peak I get about 1.2 kw.
Thank you for any help
