I’m helping a friend choose a home battery backup system, and they’re looking for something reliable and scalable for power outages. What’s the current go-to setup for home use? Tesla Powerwall is a bit over their budget, so I’m looking for solid alternatives.

Hey team, I’m considering putting together a DIY solar backup system for my garage. Anyone have recommendations on which type of batteries to use? I’ve been eyeing lithium iron phosphate (LiFePO4), but I’m curious about your thoughts.
