The A&E 80A MPPT Solar Charge Controller is a high-efficiency power management unit designed to serve as the "brain" of a medium-to-large solar power system. It is specifically engineered for the Nigerian climate, where its MPPT (Maximum Power Point Tracking) technology provides up to a 30% increase in energy harvest compared to standard PWM controllers, particularly during cloudy or dusty Harmattan days.
Available at Kara.com.ng, this unit is a favorite for 5KVA and 10KVA solar installations due to its rugged build and high current capacity.
A&E 80A MPPT Price in Nigeria (2026 Update)
The price of the A&E 80A model is influenced by its 100% copper internal components and its ability to handle high PV (Photovoltaic) input voltages.
| Model / Brand | Type | Estimated Price (2026) |
| A&E 80A MPPT | High-Efficiency MPPT | ₦265,650 – ₦295,000 |
| SMK 80A MPPT | Heat-Zinc MPPT | ₦195,000 – ₦220,000 |
| FLEXmax 80A | Industrial MPPT | ₦450,000 – ₦580,000 |
| Standard 80A PWM | Basic Regulator | ₦38,500 – ₦45,000 |
Pro Tip: While a PWM controller is much cheaper, an MPPT controller like the A&E 80A pays for itself within a year by extracting significantly more power from your panels and extending the lifespan of your expensive inverter batteries.

Why Choose the A&E 80A MPPT?
- Fast Battery Charging: In Nigeria, sunlight hours are often interrupted by rain or dust. This controller ensures that even in low-light conditions, it "boosts" the amperage to get your batteries to 100% much faster than cheaper alternatives.
- Cable Savings: Because it handles high input voltage (up to 150V), you can wire your solar panels in series. This allows you to use thinner, less expensive 6mm solar cables over long distances without significant power loss.
- Battery Protection: It utilizes a 3-Stage Charging algorithm (Bulk, Absorption, and Float). This prevents the "over-boiling" of tubular batteries and protects the delicate BMS (Battery Management System) of Lithium batteries.
- Historical Data: Most A&E models store up to 60 days of usage data, allowing you to see how much energy your roof has generated and identify if a particular panel is underperforming.
Installation & Maintenance Tips
- Wiring Sequence: Always connect the Battery first, then the Solar Panels. When disconnecting, remove the Panels first, then the Battery. Failure to follow this can damage the controller's motherboard.
- Breaker Protection: Install a DC Circuit Breaker between the panels and the controller, and another between the controller and the battery for emergency shut-off and surge protection.
- Dust Management: During the Harmattan season, dust can clog the cooling fins. Use a soft brush or compressed air to clean the unit monthly to prevent overheating and "thermal throttling" (where the unit slows down charging to stay cool).
