This is my first foray into anything electrical so excuse any ignorance.
I have a small system hooked up in my truck centered on the Renogy 50A Dual Input MPPT with a single 100W solar panel and a 100Wh LiFePo4 battery. The system worked flawlessly, keeping the battery full or near full for about a month and then stopped charging. The issue is that when the solar panel is receiving charge from the sun or if the alternator is running, the MPPT will read (bluetooth dongle) that the house battery is full and will never send more than 0.5A of charge to the house battery. Once neither source is sending power, the MPPT will read the correct charge on the house battery. The house battery will never charge and I end up having to top it off via the grid at an RV park or something.
Other thing is that I have brought the issue to Renogy on several occasions. They had me run through some troubleshooting steps and then asked me to send the device in for testing. They determined the unit was in fact faulty and they sent me a new one. This happened twice so now I am on my THIRD unit and am having the same issue. This has me wondering if I am doing anything wrong in my setup or is this Renogy equipment just garbage? Other folks online seem to love the unit. Planning to probably just switch to Victron but really just wish this system worked as advertised.
Any Ideas?
Thanks!
