A 1500VDC Solar DCDB Panel is designed to handle high-voltage direct current from large-scale photovoltaic (PV) systems. It combines multiple DC inputs from solar panel strings, providing protection, monitoring, and control functionalities. The panel ensures safe and efficient distribution of DC power to the inverter, which converts it to AC power for grid integration or usage.
Made from robust materials like galvanized steel.
Designed to withstand harsh environmental conditions such as UV radiation, dust, and moisture.
High IP rating (e.g., IP65 or higher) for ingress protection.
DC Circuit Breakers
Protect the DC circuits from overcurrent and short circuits.
Designed to handle high DC voltages and currents typical in solar applications.
Fuse Holders and Fuses
Provide overcurrent protection for each string of solar panels.
Rated for high DC voltages to ensure safety and reliability.
Busbars
Made from high-conductivity copper or aluminum.
Facilitate efficient distribution of DC power within the panel.
Surge Protection Devices (SPDs)
