How It Works

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.
Screens shown are from the current build of the app and may change.
Live energy flow
See solar, Gecko, geyser and grid in one view, with the current and target temperature.
One-tap modes
Choose AC, PV, MIX or OFF whenever you like.
Schedules that switch for you
Set timers that change the mode through the day, with control over which days they run.
Savings in rands
See what you’ve saved compared with full Eskom usage, by week, month or year.
Solar vs grid, tracked
Know your solar share, your solar hours and the geyser’s 72-hour temperature range.
Every geyser, one screen
Run several geysers from one home screen, each with its own mode and temperature.
