Sorry for the dumb question. I've given up on the error code 61 and decided to go with the USE settings. I need to change setting 26, 27, and 29 on the lv6548, but I'm having a hard time finding the right parameters on the battery. Can someone help me translate this made in China manual? See pics, I'm looking for

26. Bulk charging voltage (CV voltage)
27. Floating charging voltage
29. Low DC cutoff voltage

That is a Lithium Ion battery? I would not have it in my house, phone battery is bad enough. I charge ebike batteries outside off the bikes.

If the manual states 53.0V for constant current, then I would use that for bulk to get started. The absorption will occur at the 53.0V constant voltage. So bulk at 53.0V, I'd use a float setting about 0.5V to 1.0V below the bulk setting.

Do you have access to BMS cell data? That is key and how I determine charge voltages for my whole bank.

I'm sure it is lithium ion. It's in my metal shop far away from the house.

I can scroll on the battery screen and find cell voltages, but I'm unsure how to use the data for the above. Just wish the communication between the inverter and batteries worked...

If the manual states 530.V for constant current, then I would use that for bulk to get started. The absorption will occur at the 53.0V constant voltage. So bulk at 53.0V, I'd use a float setting about 0.5V to 1.0V below the bulk setting.

Thanks for the help, was the battery manual of any help?
 
I'd start conservative with 52-52.5v since those are 15 cell batteries.

Float 51v

Disconnect 42-43'ishvolts.
