SG830 DC MPPT Booster – High-Efficiency Hybrid Power Solution
The SG830 is a versatile DC-DC power supply module designed for flexible integration into solar power systems. It supports both Boost and Buck modes, allowing seamless adaptation to various voltage requirements. With advanced Constant Voltage (CV) and Constant Current (CC) output control, the SG830 ensures stable and reliable power delivery for a wide range of industrial applications.
Equipped with a built-in MPPT function and a tracking efficiency of up to 99.9%, the SG830 maximizes energy harvest from photovoltaic (PV) panels. It enables hybrid power supply by combining PV power with mains electricity, significantly reducing grid energy consumption and operational costs.
Key Features:
Dual Mode Operation: Boost or Buck mode selectable via software and wiring configuration
Wide Voltage Range: Supports PV input from 150–800 VDC
High-Efficiency MPPT: Up to 99.9% tracking efficiency
Flexible Communication: Modbus/RS485 support with configurable parameters via pluggable keyboard
Multiple Installation Options: Through-wall or forced air-cooling installation
Comprehensive Protection: Reverse polarity protection and fault indicators
Application Scenarios:
Ideal for integrating solar power into inverter-driven systems such as:
Solar pumps and fans
Hybrid solar inverters (e.g., SG600 series)
Industrial motor drives and frequency converters
