Smart MPPT Technology
The first feature that stands out is the Ultra-Smart MPPT (Maximum Power Point Tracking) technology. When it comes to harnessing solar power efficiently, this is a game-changer. It allows the charger to deliver a high tracking efficiency of up to 99% and a peak conversion efficiency of 98%. But what does that mean for you?
What is MPPT and Why Does It Matter?
MPPT technology maximizes the power extracted from solar panels, not only making it more efficient but also ensuring that you gain more energy compared to standard solar chargers. This technology can improve the utilization rate by approximately 20%-30% compared to competitors, meaning you get more power, quicker and more reliably.

Improved 3-Stages Charging
To keep your battery healthy, the SUNER POWER charger incorporates an improved 3-stages charging algorithm, encompassing Bulk, Absorption, and Float stages.
Understanding The 3-Stages
Bulk Charging: This stage is where the charger supplies the maximum current to the battery, taking it up to about 80%-85% of the full charge.
Absorption Charging: In this phase, the charge is delivered at a slightly reduced rate, allowing the battery to absorb energy more efficiently as it approaches full capacity.
Float Charging: Once near full charge, the device switches to this stage, maintaining the battery at 100% without overcharging, thus prolonging the battery life.
Having these stages ensures your battery is charged more effectively and safely, increasing both the performance and lifespan of the battery.
Full Safety Protections
When working with electrical devices, safety is paramount. Thankfully, SUNER POWER’s solar charger is equipped with multiple safety protections.
Safety Features Breakdown
Over-charge Protection: Keeps your battery from receiving too much charge, preventing damage.
Over-discharge Protection: Safeguards the battery from losing charge beyond safe limits.
Over-voltage and Over-current Protection: Protects against supply of excessive voltage or current, shielding your battery from potential harm.
Over-load and Short Circuit Protection: Ensures the system cannot overload or short circuit, minimizing risk during operation.
Reverse Polarity Protection: Prevents damage if connections are accidentally reversed.
Over-temperature Protection: Ensures the device operates safely even under high temperatures.
These features make it a trustworthy option for peace of mind when maintaining your vehicle’s battery.
