Solis ac coupled 5g inverter settings

[andysullivanme01@gmail]

Hi I am connecting an unbranded standalone 48v 9kwh battery with its own BMS to my Solis Rai 3k 48 es- 5g inverter.
using the USER DEFINED battery setting
I would like to know the explanations for the settings:
Charge OVV_PRO
Discharge UNV_PRO
Battery OVV_PRO
Battery UNV_PRO
and how to calculate what they should be set to, please could anyone explain
Thank you

Doing the same currently with my solis rai.
I can't use user-def unless it has CAN comm or it has an error. So I've had to use Lead Acid profile.

It will depend on your battery what settings you use. Do you know if its 15S or 16S?

Charge OVV_PRO

Charge over voltage protection. Max voltage for a cell when bms disconnects. 3.60 is good.

Discharge UNV_PRO

discharge minimum voltage protection. 2.75 is good.

Battery OVV_PRO

Battery over voltage (all the cells) protection. I would do 3.60 x number of cells.

Battery UNV_PRO

Battery under voltage protection. 2.75 x number of cells

For battery over and under, you can set just outside the range of the inverter. Backup setting if inverter cutoffs fail.

and how to calculate what they should be set to, please could anyone explain
Thank you

Note: the range for lifep04 cells is 2.50-3.65. I like to stay in the 3.00 to 3.55 range.

OK so I probably need to use the lead acid setting I guess.
I have also been told that the pack voltage is 51v nominal.
