New Geyser Management System Launched in South Africa

Sensor Networks, a South African company in smart home and energy management technology, has launched a solar farm geyser management system designed for large-scale residential developments.

As more estates switch to solar power, the upgraded system offers developers real-time visibility and centralized control over thousands of geysers, helping cut electricity costs, boost grid stability, and unlock greater value from solar installations across the country.

“Large estates often experience synchronized geyser usage during morning and evening peaks, creating strain on PV and battery systems. Our solution installs a smart controller on every geyser, all connected to SensorDesk, our company’s cloud-based energy management platform. Developers can instantly switch off units during low-generation periods, automate heating schedules, and redirect excess solar into water heating using real-time data and advanced algorithms,” says Mark Allewell, CEO of Sensor Networks. 

South Africa is moving rapidly toward solar-powered living, but without intelligent load management, developers carry the same problems from the grid into renewable systems: “If you can’t manage hot water at scale, you can’t stabilize or optimize a solar development. Our tech and system aim to solve that challenge, automatically and reliably.”

With the upgraded system, developers have real-time control over thousands of geysers—all at once. By directing surplus solar into water heating and protecting inverters during peak demand, the local tech company is giving developers a level of precision the industry has never had access to before.

Sensor Networks is now preparing to scale the technology to tens of thousands of homes nationwide, with upcoming enhancements including predictive optimization and AI-driven decision-making.
