Turn sunshine into hot water – no inverter required.

The Inge GR-4000 is a dedicated MPPT controller that feeds your geyser element directly from a solar PV array, making it an ideal solution for off-grid households, farms, and energy-conscious homeowners. With a high-efficiency DC-to-AC conversion circuit, the GR-4000 extracts up to 4,000W from your panels and delivers pure resistive power to your geyser.

How it works:

  • Connects directly to your PV string (160–350V DC, ≤15A).
  • Outputs 230V AC to your geyser element (pure resistive load only).
  • Automatically tracks the maximum power point (MPPT) for optimal performance.
  • Integrates seamlessly with your geyser’s existing thermostat – no temperature probe required.
  • Optional AC input (grid bypass) allows top-up heating on cloudy days or at night.

Key Features:

  • No batteries or full inverter needed
  • Handles up to 4kW of resistive heating load
  • IP65-rated weatherproof housing
  • Compatible with most standard electric geysers
  • Simple 3-LED interface (Solar / AC / Fault)

Important Notes:

  • Only supports resistive loads – not for use with pumps, electronics, or induction devices
  • PV input must stay within voltage and current limits
  • Grid assist function requires separate AC feed

If you're looking for a low-maintenance, solar-ready way to reduce your electricity bill and take pressure off the grid, the GR-4000 is a smart investment.
