Operational Overview:
The DNEA Solar MPPT Geyser Controller connects between the solar panels and the existing geyser. During daylight hours, the MPPT algorithm extracts maximum energy from the solar array, converting it efficiently into heat or electrical power to warm the water. The Wi-Fi feature enables users to monitor system status, analyze energy savings, and adjust temperature or operational parameters remotely, all while maintaining safety and reliability.
Conclusion:
This retrofit solution offers an eco-friendly, cost-effective way to convert standard electrical geysers into solar-powered systems. With its easy installation, intelligent MPPT technology, and remote management capabilities, the DNEA Solar MPPT Geyser Controller provides a sustainable approach to water heating, reducing electricity costs and lowering carbon footprint.
Description
The DNEA Solar MPPT Geyser Controller is a state-of-the-art retrofit solution designed to convert existing electric geysers into highly efficient, solar-powered water heating systems. By leveraging advanced Maximum Power Point Tracking (MPPT) technology, this controller enables substantial savings on electricity costs, making it an ideal upgrade for both homes and offices—where geysers are typically the single largest electricity consumer6.
-
: The DNEA controller is engineered to fit any standard electric geyser, eliminating the need to replace your existing water heater or its element. Installation is straightforward, requiring no plumbing modifications—just the integration of solar panels and the controller itself4.
-
: The controller utilizes MPPT technology to maximize the energy harvested from solar panels. MPPT dynamically adjusts the system voltage to extract the highest possible power from the solar array, typically increasing energy yield by 20–30% over conventional controllers7.
-
: Built-in WiFi allows users to monitor performance, view energy savings, and adjust settings remotely via an app or web interface. This feature provides real-time insights and control over water heating schedules, further optimizing savings1.
-
: While solar is the primary energy source, the controller automatically switches to mains electricity during periods of insufficient sunlight, ensuring uninterrupted hot water availability4.
-
: The system is designed to work with up to 4 × 550W solar panels (totaling 2200W), delivering robust heating performance suitable for typical household and office needs.
-
The DNEA Solar MPPT Geyser Controller can reduce the electricity costs associated with water heating by up to 70%. This is particularly significant given that water heaters/geysers are among the top energy consumers in most households and offices, often surpassing other major appliances like refrigerators and ovens6.
-
For context, a standard 2kW geyser running for 3 hours per day consumes about 180 kWh per month5. At an average electricity rate, this can account for a substantial portion of a monthly utility bill.
Assuming an average monthly geyser electricity cost of R600 (before solar), and a 70% reduction:
-
: R600 × 70% = R420
-
: R420 × 12 = R5,040
If these savings are compounded annually at a conservative rate (assuming electricity prices rise by 5% annually):
| Year | Annual Savings | Cumulative Savings |
|---|---|---|
| 1 | R5,040 | R5,040 |
| 2 | R5,292 | R10,332 |
| 3 | R5,556 | R15,888 |
| 4 | R5,834 | R21,722 |
| 5 | R6,126 | R27,848 |
: R27,848
This calculation demonstrates how the DNEA controller can pay for itself within a few years, especially as electricity tariffs continue to rise.
-
: Ensures the highest possible solar energy conversion, outperforming older thermal and non-MPPT solutions7.
-
: The controller intelligently balances solar and grid power, automatically optimizing for cost savings and reliability1.
-
: The WiFi-enabled interface allows users to track historical energy usage, savings, and system performance, supporting proactive maintenance and further efficiency gains1.
Water heating is consistently ranked among the top two energy consumers in South African homes and offices, often accounting for 30–50% of total electricity usage6. Retrofitting with the DNEA Solar MPPT Geyser Controller can therefore deliver the most significant return on investment compared to other energy-saving upgrades.
“Switching your electric geyser to draw power from solar panels could trim your electricity bill by as much as 40%, saving you thousands in the long run.”4
With DNEA’s advanced MPPT technology, the savings potential is even higher—up to 70%—making it a leading choice for sustainable, cost-effective water heating.
:
The DNEA Solar MPPT Geyser Controller transforms any existing electric geyser into a smart, solar-powered appliance, offering up to 70% savings on water heating costs, seamless remote management, and future-proof efficiency. Over five years, compounded savings can approach R28,000 or more, making it one of the most impactful energy upgrades for homes and offices
