I know that it is possible to make switch that switches from solar powered grid to power grid energy. But I donât know how to do it. But I would still like to know from the people who are expert in this field whether it is possible to do this kind of switching or not? If yes, then what can be done to make switch which switches from solar power grid to power grid? I would prefer such switch which is external for safety of my grid system. Any advice pertaining to my query would be highly appreciated. Thanks.
