Hi I have a color control gx and the pv power is not reading it just says 0 but lights up. Everything on system working and battery charging normally. The pv power screen just stopped reading it has been working fine and no settings were changed. My problem is that I cannot see how much power the solar system is inputting but it is providing power normally so it just this one screen not working all else ok. Tried reconnecting, shutting down etc. Can anyone please tell me if this can be fixed, thank you.
