Power your off-grid setup with a 4kW pure sine wave inverter that lets you combine solar, utility and battery power to suit your needs.

  • Solar charging: The built-in 140A MPPT charger supports up to 5,600W of PV power across a 55–350Vdc MPPT range, giving you flexibility when configuring a solar array.
  • Flexible operation: Choose Only Solar, Solar First or Mains & Solar charging, then set SBU or SUB output priority to match your power-use preferences.
  • Clear controls: Check settings on the 6.25-inch LCD and use the touch buttons; the 24Vdc battery system can also operate without a battery.
  • Useful output and protection: You get 120Vac output at 50/60Hz, plus overload, over-temperature and output short-circuit protection, cold restart, and automatic restart as PV power recovers.
