Has it ever happened to you that the solar regulator does not detect the battery??
It is very easy to detect because the battery icon flashes and it is “empty”
Solving it is very simple, It's probably because you have a lifepo4 battery., and you have left her to 0, or the fuse has blown, or is the circuit breaker failing?. The first thing would be to check the fuse and circuit breaker., If they are fine, you have to reactivate the lifepo4 battery that you left behind. 0.
You can do this by starting the vehicle's engine., or with a SPECIFIC lifepo4 charger.
If you reactivate the battery but it does not charge, you have to restart it, and it is done by lowering the thermal of the solar panel and that of the regulator, and immediately reset the regulator, and finally the one with the plate. That order is very important otherwise it will still not load.
