The Geyser Gecko is a smart geyser controller that completes your solar geyser conversion in 3–5 hours. It sits between your geyser, your solar panels, and the grid, intelligently choosing the cheapest source available, every second of the day.

01

Solar heats first

Three standard PV panels connect directly to the Gecko controller. On a sunny day, that power goes straight into your geyser’s heating element, no inverter, no battery, no energy lost converting to AC and back.

02

Grid steps in automatically

Cloudy day, or the tank’s run low overnight? The Gecko senses it and blends in grid power automatically. You never have to think about it, and you never run out of hot water.

03

You stay in control

Set your target temperature, schedule timers, and watch your solar vs grid split and rand savings live from the Geyser Gecko app, on any geyser, from anywhere.

The app and the intelligence behind it

Set it once. Geyser Gecko does the thinking.

Schedules pick the right power source at the right time, solar first and grid only when it’s needed, while the app shows you exactly where every watt is going.
