SI-CD Series PV Combiner Box Overview

The SI-CD series PV combiner box is used to connect a number of photovoltaic panels with the same specifications into photovoltaic series, and then these series are connected in parallel to the box. The DC power collected by the convergence box will be used by the controller, DC distribution cabinet, solar inverter, AC distribution cabinet and other equipments to form a complete photovoltaic power generation system. In addition to standard configurations, we also offer customized services, including the option to add a high-temperature version and a monitoring unit.

• DC Surge Protection Devices (SPD) - SPDs divert excess electrical energy to the earth, thereby shielding the system against potentially harmful transient voltage spikes.

• DC Molded Case Circuit Breakers (MCCB): MCCBs for Direct Current (DC) applications are integral components in high-power photovoltaic (PV) systems, safeguarding electrical circuits against current loads ranging from 63 to 630 amperes. It's crucial to recognize that the precise current rating for an MCCB within a string combiner box is contingent upon the specific design parameters and the scale of the PV array, as varying systems necessitate distinct levels of circuit protection.

• Anti Reverse Diodes: These diodes are designed to allow current to flow in only one direction, preventing reverse current flow which could occur during periods of low light or at night. This helps protect the solar panels and other system components from potential damage due to reverse current.

• Direct Current (DC) Fuses: PV string fuses are specifically designed for photovoltaic (PV) string applications, serve to cut off electrical current in the event of a fault. These fuses are instrumental in safeguarding the PV system against overcurrent conditions, which might otherwise lead to system damage. They are strategically placed to protect each PV string individually from issues such as short circuits.

• Ground Wire: The ground wire is a critical safety feature that provides a path for electrical current to safely discharge into the ground in case of a fault. This helps to prevent electrical shocks and reduces the risk of fire, enhancing the overall safety of the PV system.
