SOC and Tail Settings

Question

question

burnttech asked Mar 24, '21

I added two photos showing the SOC went to 100% very quickly and was thinking I might need to change the settings for the tail percent?

2x SLR125 125ah agm batteries

Battery size = 250ah

Charged Voltage = 13.1v (thinking of changing this to 13.2)

Charge Time = 3m

Change Tail = 4% (not sure about this one)

Small charging currents most likely from PV often cause a early jump to 100%.
A higher "charged voltage" can help.

Ya sounds like I need to change the higher volt and play with settings tail while using PV. Great Video
