Solarthon MPPT Solar Charge and Discharge Controller
The Solarthon MPPT Solar Charge and Discharge Controller, developed by Guangdong Solarthon Technology Co., Ltd., is an advanced charging method designed to optimize the power generation of solar panels. With its maximum power point tracking (MPPT) feature, this controller can monitor the real-time voltage of the solar panel and track the highest voltage and current values. This ensures that the system charges the battery with the maximum power output, maximizing energy extraction from the solar array.
Unlike other controllers, the MPPT mode of this series is fully automatic and does not require any user adjustment. As the maximum power point of the solar panel varies with environmental conditions, this controller intelligently tracks and adjusts to the changing conditions, guaranteeing optimal energy conversion.
Key Features:
- MPPT technology for efficient power generation
- Real-time monitoring of solar panel voltage
- Automatic tracking of maximum power point
- Optimized charging for maximum energy extraction
With the Solarthon MPPT Solar Charge and Discharge Controller, you can harness the full potential of your solar array and enjoy the benefits of clean, renewable energy.
