What makes Elon Smart Water different?
It’s the only solution that retrofits standard electric geysers and is solar PV-ready—combining smart thermostat control, connected monitoring and seamless solar integration.
Can the system be retrofitted to my existing geyser?
Yes — if you have a compatible geyser (for example from your preferred brand), your electrician can replace the thermostat with the Elon smart unit and convert it into a smart, solar-ready heater.
What is the difference between the Elon 100 and the Elon Smart Water solution?
The Elon 100 is a solar-PV water-heater kit. The Smart Water solution is a next-generation smart thermostat with solar-PV capability. Both allow you to connect solar PV modules to your standard electric geyser, but the Elon Smart has additional benefits and capabilities, including being able to see the water temperature, monitor and control your geyser from a smartphone.
How many solar panels or what size solar array do I need?
The size depends on your hot-water usage, location and array size; as a guide we recommend a minimum of around 1 kWp of solar PV for the retrofit system.
How do loadshedding and grid outages affect my system?
If there is sun the system can heat with solar; if there’s no grid and no solar it will pause heating. During load-shedding you still benefit whenever solar is available.
