Full assembly of the EG4 cabinet and rack from Signature Solar. Loading it up with over 30 kWh of LiFePO4 batteries, 51.2V (48V). Wiring. Custom Fuse for over-current protection. Updating the firmware and top-balancing. Whew! That's a lot to cover in this video, so let's get to it.
My goal in this video is to have a step by step guide to help walk you through the process of setting up a large battery bank for your whole house backup. I use this off grid for my 100% electric house.
