Infinisolar 3KW Charging Current 0.1A issue

RVSolar
in Solar Power

Featured Replies

Hi all,

I have an Infinisolar 3KW inverter set up at home.

I only used as a Grid Tied inverter for the last few years, and have now been getting some load shedding in Namibia as well and decided to add 4 x 200AH 12V Lead Carbon Batteries.

However, for some reason the charging current is stuck hopping between 0.0A and 0.1A

This is with floot charge of 54.0V and Bulk charge of 56.2V

The PV input power is also around 2.8KW and load around 0.5KW so there should be ample power for charging the batteries up to 54.0V?

Grid Tied with Backup ii - Can feed into grid and AC not allowed to charge battery (PV only as charging source)

Charging current max at 25A

 

Please let me know what I can try, thanks.
