Was talking with my installer company today, and I asked about the ability to grid charge batteries because I would be the ER SGIP program, and not be getting an ITC. I got back an answer from him I have never heard before.
He told me the SGIP program requires batteries to be charged from solar at least 75% of the time. So independent of the ITC, assuming this is the requirement, I could now see why it would have to be this way.
Has anyone else ever heard this?
