    Except it self terminates the backflow once mains is powered off so it is it’s own backflow prevention breaker. It already does what is legal. Just needs approval.

        My mom is a boomer who was fortunate to inherit her mom’s house when both my dad and her mom died within months of each other.

        She’s on a fixed income, but was able to get rebates and sincerely Solar relatively early, 2015 I think. Her medium sized northern US house was previously heated with wood pellets, but now has a dual zone heat pump, and the solar has paid for itself in electricity savings in the first 4 years.

        She’s lost a panel and inverter since then (inverter was under warranty), but the replacement inverter is less than half the size, and leaves room in the garage for a battery someday.

        It’s worked out very well financially for her. I’m jealous because I don’t have the cash or sunny roof space to make it work at my house.
