Help me decide about energy grants - heat pump, batteries?

It’s clear that you are leaning towards the batteries, nothing wrong with that plan.

I will note that panel prices are pretty low right now, and that prices on LiFePo batteries appear to be steadily dropping.

I think I might be dumb to say no to free heating equipment and low trouble heat… and I fear it’s because I’m burnt out on building projects lately. That is flavoring my lean, and I want to be set straight if that’s the right answer. We have a gas generator, but it’s not standby, so we don’t use it unless power is out for a while. I’m also wondering if battery technology will further improve in the next few years, so that we’d get smaller/more efficient batteries if we waited. Standby would indeed be nice, though.
