Whether you already have solar panels, and an inverter installed or you’re planning a new system, the Geyser Gecko is a perfect add-on:
- For home owners who want to save more on their electricity bill,
- For small businesses aiming to optimize solar use and reduce operational costs.
The Geyser Gecko utilizes energy generated by solar panels to heat your geyser. This allows you to heat water using solar energy, reducing the need to draw power from the grid or your battery system.
Water heating is one of the biggest energy consumers in most homes. By handling this load separately, the Geyser Gecko:
- Preserves battery life in hybrid/off-grid systems,
- Reduces strain on your inverter,
- Helps prevent overloads during peak usage times.
- Maximizes Solar ROI
The Geyser Gecko ensures you’re getting 100% value from your solar panels—by storing energy as hot water, which can be used throughout the day and night.
While the Geyser Gecko does not export electricity back to the grid, it is the most cost-effective and efficient solar inverter solution for water heating.
Yes, the Geyser Gecko can absolutely be installed alongside other solar inverters, and doing so can create a powerful, efficient, and cost-effective solar energy solution for your home or business. It enhances your solar system by:
- Making smart use of excess solar energy,
- Lowering electricity costs,
- Reducing strain on batteries and inverters,
- And increasing the overall efficiency of your renewable energy setup.
The Geyser Gecko is designed to complement existing solar energy systems, not compete with them. This means you don’t have to change your current inverter setup – Geyser Gecko works in harmony with it to increase your energy efficiency and savings.
The Geyser Gecko is designed for simple installation and doesn’t require major changes to your solar or geyser setup. It can be:
- Installed onexisting electric geysers,
- Configured to prioritize solar power over grid power,
- Managed easily via onboard controls or an app (depending on the model).
Yes, you can absolutely use your current geyser with the Geyser Gecko – no need to replace or modify it. The Geyser Gecko is designed to work with standard electric geysers up to 4kW. This means:
- No plumbing changes required
- No new geyser installation needed
- No expensive upgrades necessary
The Geyser Gecko requires just 3 standard solar panels to operate effectively.
These 3 panels – typically around 550W each – provide enough energy to:
- Power the Geyser Gecko during the day,
- Heat your water using free solar electricity,
- And reduce your reliance on grid power or batteries.
This setup ensures the Geyser Gecko can make maximum use of available sunlight while keeping your installation cost low.
The Geyser Gecko works independently of other solar inverters, so these 3 panels can be dedicated purely to heating water.
Either way, you’ll enjoy hot water powered by the sun, with no need for expensive solar geysers or complicated solar thermal systems.
Your installer will:
- Help select the right type and wattage of panels,
- Mount them in the optimal location,
- Connect them to your Geyser Gecko for efficient solar heating.
The Geyser Gecko is compatible with most standard PV (photovoltaic) solar panels, making it easy to source and install the right setup for your system.
- Type: Standard monocrystalline or polycrystalline PV panels
- Power Rating: Typically 400W – 600W per panel
- Voltage: Panels wired to match the Geyser Gecko’s input requirements (your installer will ensure correct configuration)
- Quantity: Usually 3 panels for optimal performance
Whether you already have panels or are installing new ones, your installer can match the Gecko with panels that meet its requirements.
Your installer will confirm the panel sizing and placement during the site visit and include it in your quote.
Installation of the Geyser Gecko is quick and hassle-free. In most cases, it takes about one day to complete.
Because the unit works with your existing geyser and electrical system, there’s no need for complicated plumbing or structural changes – making the process smooth and efficient.
While one day is typical, the exact installation time will be confirmed during a site visit by one of our trusted installers.
Yes, a site visit by an installer allows the installer to assess your current geyser and electrical setup, confirm your geyser’s compatibility, determine where to place the 3 solar panels, and provide you with an accurate quote and timeline.
No, the Geyser Gecko is not installed in the roof.
Instead, it is installed next to your electrical DB board (distribution board) in a well-aerated, accessible location – typically in your garage, utility room, or near where your geyser’s electrical circuit is managed.
The Geyser Gecko is an electronic control unit, and it needs to be kept cool and ventilated for optimal performance and safety.
Roof spaces can become extremely hot, dusty, and difficult to access – not ideal for sensitive equipment.
Yes, the Geyser Gecko can be used completely off-grid.
It is specifically designed to operate independently of the electrical grid, making it an excellent solution for off-grid homes, farms, lodges, and other rural locations.
How It Works Off-Grid:
- The Geyser Gecko connects directly to 3 solar panels (±550W each).
- It uses DC power straight from the sun to heat your existing electric geyser.
- No inverter, no batteries, and no connection to the grid is required.
- This setup ensures reliable hot water using only solar power – even in areas with no access to electricity.
The Geyser Gecko is designed to intelligently use both solar power and AC electricity, giving you the best of both worlds: maximum energy savings with guaranteed hot water.
Here’s how it works:
- Primary Source: Solar Power
- The Geyser Gecko connects directly to 3 solar panels (±550W each).
- It prioritizes solar energy to heat your geyser whenever the sun is shining.
When there’s not enough solar power (e.g., at night or during cloudy weather), the unit automatically switches to AC power from the grid or your backup system (like an inverter or generator).
This ensures you always have hot water, regardless of weather conditions.
The Geyser Gecko device itself is maintenance-free, designed for long-term reliability without the need for regular servicing. However, solar panels connected to the system do require occasional maintenance to ensure optimal performance. We recommend cleaning the panels a few times a year to remove dust, debris, or bird droppings that can reduce efficiency. Always follow safety guidelines or consult a professional when maintaining your solar panels. The Geyser Gecko will continue to operate efficiently as long as the solar input remains unobstructed.
No, the Geyser Gecko must be installed by a qualified electrician.
