Client Wanted

Major off-grid power for a family of four doing long, unplugged stays in their large fifth wheel (50-amp service)

Existing System

  • 50-amp service
  • Conventional 200 Ah lead-acid (AGM) battery bank
  • No generator and no inverter for off-grid AC power

What We Did

  • Designed a system for the large front bay, keeping room for a small back-up generator and existing hydraulics
  • Built a battery rack using extruded 2020 aluminum for the 3x 24-volt, 200-Ah server rack batteries and a bay expandible to 5; current configuration is for 14.4 kwhs of battery storage!
  • Built a battery rack suing extruded 2020 aluminum for the three, 24 volt, 200ah, server rack batteries. Bay is expandible to five. Current configuration is for 14.4 kwhs of battery storage!
  • Installed smart phase selector to allow full use of existing 50-amp power panel as well as a built-in surge protector
  • Roof PV is two banks feeding into two separate charge controllers; 1530 watts with room for more
  • Went with large Victron Quattro inverter and Victron Orion-Tr alt chargers in dual configuration for max charging of the giant battery bank
  • Final touch is a Cerbo GX unit connected to the Touch 50 screen for real-time power readout inside the living area
