Renogy One SOC%

[Ozelec]

I have installed a Renogy Shunt 300 and have paired this to a Renogy One Core.

The problem is the SOC% displayed steadily drops as it seems to be only recognising discharge amps (from loads etc) but does not reflect charging amps from the PV system connected to the battery.

Can anyone suggest a method for correcting the One Core so it reflects charging amps and therefore has a more correct SOC%?

How is it wired? Can you post pictures?

Maybe not clear from the documentation how the charge controller should be connected, but the only thing connected to the battery negative should be the shunt. The charge controller and every other device should connect to the P- terminal on the shunt.

Same boat here. I have checked the wiring many times and it is fine.

Yeah, One sec

B to battery neg P to inverter negative. B1 direct to battery and temp sensor on battery.

All negatives in the system connect to P-. No negative cables connect to the battery negative other than B-.

Looks right, where is the charging system connected to the battery?
