Black Friday Solar Equipment Deals! Biggest Battery/Inverter Sales of the Year
Nov 22, 2025
Welcome to the MattMan Solar Battery Black Friday Deals!
This is the once-a-year mega sale where I round up the best solar deals, highlight the lowest prices, and share my personal picks for batteries, inverters, and complete solar kits.
If you’re planning a DIY solar build — RV, shed, off-grid cabin, or home hybrid system — THIS is the weekend to buy.
Prices like this only happen during Black Friday, and most of these deals disappear fast once inventory dries up.
