@mwl @angelastella I was going to say that. I would avoid Lead-Acid due to poor longevity and go instead for LiFeO₄. Also today there are a very many options for power banks that handles everything with direct hookups for PV. |
@angelastella lots of issues to juggle here, absolutely.
Batteries are advancing quickly. Every year, better options appear. Deciding when to build the battery system is an ongoing struggle.
