Cabins and Farms

Far from the grid, or tired of trenching power to a barn, you build a real off-grid system: a ground-mount array, a 48 V battery bank and an all-in-one inverter with 120/240 V for well pumps and shop tools.

Solar Panels Make the power Ground mounts are the farm default: easy to clean, aimed exactly south, and no roof to leak. Battery Store it for later Rack-mounted 48 V LiFePO4 modules are the common off-grid bank: add one at a time as needs grow. Inverters Turn it into power your stuff can use An all-in-one off-grid inverter combines the charge controller, the inverter and a generator input in one box. Build Your Own Kit Pick all three that fit Enter your daily use, how many cloudy days to ride through, and your biggest load. The calculator sizes a 48 V system.

Know this first

  • 48 V systems carry the same power at a quarter of the current of 12 V, so wires stay thinner over long runs.
  • Split-phase 120/240 V output runs well pumps and other 240 V loads.
  • EG4 advises purely off-grid systems to keep a backup generator for long cloudy stretches.
