Future-Proof Your Geyser Without Replacing It

If you’re feeling the pressure of rising electricity costs in South Africa, your electric geyser is likely one of the main culprits. Traditional geysers can account for up to 40–60% of a household’s energy usage. But what if you could convert your existing geyser into a solar-powered one — without replacing the whole unit?

Enter the Pi²R IX & Micro Solar Geyser Controller, now available through LMS Electrical. This clever device lets you use solar power to heat your water, reducing your reliance on the grid and helping you save up to 60% on geyser-related electricity costs.

What Is the Pi²R Solar Geyser Controller?

The Pi²R controller is a smart energy management unit that lets you:

•  Connect your existing electric geyser to solar panels.
• Power your geyser directly from solar energy using DC input.
• Avoid replacing your geyser or element — it’s plug-and-play compatible.
• Monitor performance via an optional digital display.
• Stay compliant with SANS 10400 standards for South African homes.
• Remain off-grid ready, making it ideal for load-shedding relief.

How Does It Work?

Instead of heating your geyser with expensive municipal electricity, the Pi²R controller redirects solar-generated power into your geyser. Using MPPT (Maximum Power Point Tracking), it ensures your geyser gets the most efficient power output from your panels, even on cloudy days.

It’s like giving your geyser a brain that knows when to use solar, when to fallback to grid power, and how to use both smartly.

How Much Can You Save?

Let’s break it down:

• A typical electric geyser uses 3–4 kWh per day.
• At R2.50 per kWh (Eskom pricing), that’s roughly R225–R300 per month.
• Switching to solar with a Pi²R controller can reduce geyser electricity usage by 40–60%.
• That’s a saving of R1,800 to R2,400 per year — just on hot water.

And if you’re a business with multiple geysers? The savings scale dramatically.

Added Benefits

• Load shedding ready: Geysers continue heating during the day even when Eskom’s off.
• Extend geyser lifespan: Controlled energy flow protects the element.
• Low maintenance: Set it and forget it – the Pi²R does the work.
• Eco-friendly: Lower your carbon footprint by using free energy from the sun.
