The GeyserWorx Controller is used in GeyserWorx' hot water systems. The system utilizes a dedicated solar PV array to heat water in your existing geyser during the day. It uses micro-processors to feed the heating element with DC voltage directly. During the day, the solar PV will heat your water to 70 ⁰C. AC power will be used during times when the Solar Power is not sufficient to keep your water at all times above ⁰55 C. This will:

        • Ensure you always have hot water;
        • Save on your current electricity bill (between 30% to 50%);
        • Reduce the load on your current solar installation;
        • Give you all the control over your hot water through an App on your phone.


Available models:
- Single Controller for Single Geysers
- Dual Controller for Dual Geysers
