Vertical Mount 48V LiFePO4:
Powerpro Battery by EG4

If you are about to purchase server rack batteries, check these out first. They come at a lower price and smaller foot print and can be mounted outside (if you buy the outdoor rated model). The indoor rated model is actually cheaper than any server rack battery on the market and with more features!

This is my new go-to 48V battery. Check out their features:
  • 14.3kWh! Equal in capacity to almost 3X server rack batteries
  • Outdoor or indoor rated. On the outdoor rated model, the main terminals, communication ports and screen are all waterproof
  • Use with communication or without. All you need is a 48V inverter from any manufacturer and you are good to go!
  • Code Compliant for ESS
  • Works with all common grid interactive inverters like sol ark and luxpower
  • Lower in price than server rack batteries!
  • Comes with 500A rated copper bus bars and quick connect amphanol connector plugs
  • Easy to install. They are heavy, but with a hand truck you can place these wherever you need them. I mount mine on the ground and secure them to the wall, but they are designed to be direct mounted to the wall. The choice is yours!
Currently this is what I am running my shop with. The photo on the left is my current system.
