Sleeping mode, is all that the new solar will do.. After 4 hours on the phone with the tech today, only thing we figured out is possible bad combination box or yet another bad controller or both.. A tech is coming out in the morning to take a look.. There is power coming off the panels, but nothing from the combination box. First it was not getting all the parts sent, next bad controller and now this… We wonder is it ever going to work, did we waste money? Right now anxiety, moods, regret are high…
