Build your own solar battery and save thousands

Warning! This is a dangerous DIY procedure. I rebuilt this battery using the best LiFePO4 cells on the market (Grade A, CATL). It was a dangerous build, but I saved thousands of dollars compared to buying pre-built server rack-style 48V batteries.

Server rack batteries are a great choice if you don't want to DIY your own battery. I recommend EG4 batteries from Signature Solar. Here is an affiliate link to the battery rack I use daily: https://signaturesolar.com/eg4-lifepower4-lithium-batteries-kit-30-72kwh-6-server-rack-batteries-with-free -pre -closed-building-assembled-with-door-wheels-bus-bar-covers/?ref4_rHcgZ9x-TiF-

Schneider Inverter: The Schneider XW PRO inverter has been powering my home this year without any problems. I can recommend it. https://signaturesolar.com/schneider-conext-xw-pro-6-8kw-inverter-charger-48v-120-240v/?ref4_rHcgZ9x-TiF-
