At least here in CA, if you are on the grid but don't have a battery then you will go black with everyone else even if you have solar. This is a safety measure

At least here in CA, if you are on the grid but don't have a battery then you will go black with everyone else even if you have solar. This is a safety measure for the technicians from the electrical company fixing the issue. According to another comment the additional cost of a battery is between $6,000 to $10,000.
- SAI_Peregrinus 6y agoIt's not the battery that matters, rather it's whether you get an automatic transfer switch (ATS). Those are more in the $500-1000 range. Of course without a battery that only helps when it's sunny, so you still want a battery. But the battery isn't the safety measure, the ATS is.
