About a year ago, I put together a battery setup for camping, mostly based on reading posts on these forums. For this setup, I use a couple 100 watt panels in series, an Ampere Time 100Ah LiFePO4 battery, an EPever Tririon2210N controller with MT50, and a 24V 15A power supply feeding the charge controller's solar input when charging at home. This setup has worked perfectly for numerous camping trips. This past weekend, I didn't take panels, since we were pressed for space, and the battery never dropped below 45%.
When I got home, I noticed the battery appeared to charge much quicker than normal. Instead of actually charging, it had stopped at 45.4% with a battery voltage of 10.5. When I first connect AC to the power supply, the MT50 shows it charging at 14.6V 10A for a couple seconds with the solar input (power supply) at 24V. Then, the output voltage from the power supply still shows 24V but zero amps. Also, I noticed that the controller LED that's normally green for the battery is now red, likely due to the low voltage, I assume.
I've verified the input voltage to the controller and the battery's voltage with a separate meter. I used parameters I found here to set up the controller, and they are listed below. Basically, I need some help troubleshooting this and can certainly do any testing necessary to help with this. My first thoughts were that a setting is wrong, and the battery is at a lower state than normal, but now I wonder if the power supply is at fault. I don't have a spare power supply but can order one if necessary. Thanks much in advance!
