How to correct inaccurate SOC value
What voltages you use to charge your lifepo4, and what voltage you use for establishing 100% SOC, is all a matter of personal preference---within reason, of course That being said, I believe your "resting" voltage is a tad optimistic. A charge voltage of 13.60v (3.400v cell voltage) will still charge a 12v lifepo4 battery to 99-100% SOC.

6 FAQs about [Solar control voltage display is inaccurate]
How do I know if my solar charge controller is bad?
To diagnose a potential issue with your solar charge controller, measure the voltage using a multimeter. If the voltage is lower than expected, it might be time to recharge or even replace it. For a thorough assessment of the overall health of the solar charge controller, carefully inspect the controller. In my two decades as a solar expert, I’ve found this to be an essential step.
Why is my solar charge controller not working?
If the controller is not working, check the voltage of the battery to ensure it’s within the operating range of the solar charge controller. If you continue having issues, it might be necessary to consult the manufacturer’s guide or contact technical support.
What is a solar charge controller display?
A solar charge controller display provides necessary information about battery voltage, charging current, and accumulated system power. It is essential for monitoring performance and identifying any underlying issues. The most common cause of solar charge controller display problems is a broken display line.
Why is my solar panel not working?
If the PV voltage and the battery voltage are both below 6V, the display will not power up. It could also be that the LCD display is not properly inserted into the socket on the solar charger. 4.2. The display segments are faint or missing The screen is blank or faint, but the back-light is still operational.
What happens if a solar charge controller is overcurrent?
Overcurrent poses a significant risk to solar charge controller systems, potentially leading to damage and operational failures. It occurs when the current passing through the controller surpasses its designated capacity, often due to causes such as mismatched components, faulty wiring, or system malfunctions.
How do I know if my solar charger is faulty?
In the case of reverse PV voltage, the solar charger will not indicate an error. The only way to detect reverse PV voltage is by the following signs: The controller is not charging the batteries, the charge current is zero. The controller is getting hot. The PV voltage is zero, or close to zero.
