My neighbor Bill and Audrey are putting up the same amount of solar as you see here, (12kW) but they got talked into not using batteries due to using the Federal 40k grant. Kate https://youtu.be/_fYCN9glJN8?si=KU2Mf03Pqn9D0Rsg&t=135 told me last night that Sexsmith couldn't get the grant if they spent money on batteries. This doesn't make sense to me. Sexsmith had 7 brown outs this year. A lot of money spent in appliance replacement. If they would have done the solar install like I did with a battery backup, they wouldn't have had all these brown outs.
But you already know I like decentralized stuff. Electricity and money :)
