SG830 DC MPPT Booster Module — Solar DC-DC Power Converter
The SG830 DC MPPT Booster Module is a high-efficiency DC-DC power conversion module designed to integrate photovoltaic (PV) power into the DC bus of variable frequency drives (VFDs). By enabling hybrid PV-grid power supply, it significantly reduces mains electricity consumption in solar pump inverter and industrial motor drive systems.
The module supports both Boost and Buck operating modes, configurable via software, making it compatible with a wide range of PV array voltages (150–800VDC) and inverter DC bus voltages.
Key Features
Dual-Mode Operation: Boost mode (low-voltage PV → high-voltage DC bus) and Buck mode (high-voltage PV → lower-voltage DC bus), software-selectable via pluggable keyboard
Built-in MPPT: Advanced Maximum Power Point Tracking with efficiency >99%, ensuring maximum solar energy harvest at all times
High Conversion Efficiency: Power transfer efficiency ≥95%
Wide Power Range: Available in 3KW, 5KW, 8KW, 10KW, and 16KW models to match different system sizes
CV & CC Control: Configurable constant-voltage and constant-current output limits for safe operation
RS485 Modbus Communication: Standard Modbus RTU protocol for remote monitoring and parameter setting; all operating data (voltage, current, power, energy meter, temperature) accessible via communication
Pluggable Keyboard Interface: On-site parameter configuration and real-time monitoring without external tools
Through-Wall Installation: Forced air-cooled design with through-wall mounting for effective heat dissipation
Comprehensive Protection: Over-voltage, under-voltage, and reverse polarity protection built in
DI Terminal Support: 2-channel digital input for external control signals

Hybrid PV-grid industrial motor drives (HVAC fans, compressors)
Solar-powered off-grid and hybrid energy systems
Retrofitting existing AC drives with solar input capability
Connection
PV+ / PV- (Low-voltage side): Connect to PV array (Boost mode) or inverter DC bus (Buck mode)
OUT+ / OUT- (High-voltage side): Connect to inverter DC bus (Boost mode) or PV array (Buck mode)
Power flows automatically from low-voltage side to high-voltage side; no reverse flow.
WARNING: Strictly observe polarity — reverse connection will damage the module!
