Hi all,
I have replaced my complex's battery backup system Gel batteries with Lithium (2x 12V Deltec 100Ah in series).
The (Axpert type) inverter does not have a Li selection for battery type, so I set it to User. All working fine, batteries show fully charged and they handle 2hrs load shedding dropping to 26.2V.
Two questions:
The battery spec mentions a charging voltage of 14.2-14.6V so I have set the inverter to 28.6V. What should the float voltage be set to? Lower than the bulk, or the same?
Should I get a battery balancer? How important is this?
Appreciate any advice.
