Why the Hercules 6000W is a Game-Changer

1. Automatic “Brain” for Off-Grid Systems

When paired with GridFree’s PRO Series or SolarNest inverters*, the Hercules:

  • Shuts off automatically once batteries are full—saving fuel and hassle.

*Auto-start requires PRO/SolarNest systems for advanced integration.

2. Quiet, Fuel-Efficient Power

  • 64 dB Noise Level: Quieter than a washing machine (ideal for cabins or residential areas).
  • Inverter Technology: Adjusts engine speed to match load, using 40% less fuel than conventional generators.

3. Built for NZ’s Tough Conditions

  • Rugged, weather-resistant design.
  • Pure sine wave output—safe for laptops, phones, and appliances.
  • 12-month warranty + GridFree’s local support.
