15 A MPPT Solar Charge Controller for Lead Acid batteries.
This Solar Controller is ideal for remote solar installations.
Features
- Uses Maximum Power Point Tracking (MPPT) charging method. MPPT is superior to cheaper Pulse Width Modulation (PWM) chargers, as it continually tracks the voltage from the solar panel input to extract the maximum power.
- Supports Lead-Acid batteries: Sealed, Gel, and Flooded.
- Auto detection of 12 or 24 V systems. Can be used with:
- 12 V batteries & '12 V' Solar panel(s), or
- 24 V batteries & '24 V' Solar panel(s)
- Many inbuilt safety protections:
- Solar Panel: Over current, short circuit, and reverse polarity.
- Battery:
Battery Protections: Reverse polarity, over voltage, over discharge, overheating, temperature sensor error, load overload, and load short circuit.
- Aluminum housing for better cooling
- Rated IP68 - dustproof & waterproof
- Very low self consumption. 0.2 W (12 V) | 0.3 W (24 V).
This minimises battery consumption at night, and minimises temperature increase on hot days.
Why We Like this Product
The build quality is excellent.
It is ideal for remote installations due to its low self consumption (i.e. high efficiency).
It is small and easily mounted.
