I had ordered two of these and it worked perfectly for the first three weeks. Then suddenly both switched to the GRID supply (source B) even while the solar power was present. Now both are fixed (jammed) on the GRID supply (source B) line. It does not come back to the solar side when in auto mode. Even if I switch it to manual and try and turn the switch to solar (source A) I cannot. Picture shows one of them with the switch on auto but selector is on grid supply (source B). This was very disappointing!!!
