Retrofit grid-tied solar with backup

  • Retrofit seamlessly with installed PV inverters
  • Complete reliability with industry leading solution
  • Seamless switchover to keep your power on during outage


During grid outages PV Inverter production cannot occur, so a home with a PV inverter system installed will not have power during an outage. However for homes that have a PV Inverter system installed and are already selling power to the grid, it is still possible to retrofit backup power using Conext™ XW ProXW+ or SW inverter chargers. In a FIT program either Conext™ XW Pro, XW+ or SW is added behind PV inverter to provide backup, no change to PV inverter FIT wiring is required. However backup power is limited to the capacity of the battery bank and the solar system cannot be used to charge the batteries while the grid is down. In a NET meteredprogram the Conext™ XW Pro or XW+ inverter charger is added in front of PV inverter to provide backup power. The PV inverter is rewired from the grid connection to critical load subpanel and AC Couple is on AC Output port. Conext™ solutions includes:

  • Seamless switchover
  • Powerful load starting
  • Fast efficient ChargePower technology
  • Scalable battery reserve
  • CouplingPower – AC couple with PV power
