EV CHARGING FOR OFF-GRID

Use your off-grid solar to fuel your EV.

Pairing an Evnex charger with an off-grid system lets you decide when to send energy to the vehicle, the home, or the batteries — with live visibility and smart limits.

  • Works alongside battery and generator setups designed for remote properties
  • Scheduling tools so charging happens when you have surplus solar available
  • Detailed usage data to help you plan storage and future upgrades
