The Geyser Gecko Solar Geyser Solution is the perfect way to turn your traditional electric geyser into an energy-efficient hybrid heating system. Designed to use solar power efficiently, this solution not only helps you save significantly on electricity bills but also makes your home more sustainable. With support for geyser elements up to 4 kW, the Geyser Gecko can operate purely on solar (PV mode) or as a hybrid that combines both AC and solar power. Easily monitor and control your system with the Geyser Gecko mobile companion app, making energy savings effortless. Whether you're looking to cut energy costs, reduce your environmental impact, or both, the Geyser Gecko Solar Geyser Solution is a smart, powerful, and easy-to-use choice.
Solar Geyser Solution
It uses solar panels to heat up your existing electrical geyser (up to 4 kW geyser elements supported). It can be set up to operate as a hybrid between AC and PV power, where AC power is partially used to heat up the water and the solar panels heat it up further. The PV mode, where only solar panels are used to heat up the geyser. It can be monitored and configured remotely by using the Geyser Gecko mobile companion app.
-
Geyser Gecko PV Geyser Controller: This component directs power from the solar panels directly to the geyser's heating element, allowing the system to heat water efficiently using solar energy without converting it to AC power first.
-
3 x 565W Solar Panels: These high-wattage panels provide a total of 1.69 kW of power, supplying ample energy to heat water in the geyser. This is ideal for households looking to reduce grid dependency for water heating.
-
Roof Solar Mounting System: This ensures secure installation of the panels, protecting the setup from environmental factors and aligning panels for optimal solar exposure.
Key Features
- Easy Installation: It can be installed into existing electrical geyser installations and does not require a different geyser element.
- Save Energy: More than 50% savings on geyser power usage.
- Powerful: Supports geyser elements of up to 4kW.
- Accurate Readings: Accurate geyser temperature measurement with a digital probe (supplied with the Geyser Gecko).
