PV Protection Products

PV cable, also known as DC PV cable, are an indispensable component of solar photovoltaic power generation systems. They connect photovoltaic panels to inverters. These cables use tinned copper conductors, offering strong electrical conductivity and oxidation resistance. They feature dual-layer sheathing for enhanced protection, high strength, wear resistance, and are waterproof and oil-resistant.

The MG1-63 miniature DC circuit breaker, with a rated voltage up to DC1200V, features a special arc extinguishing and current limiting system. It swiftly disconnects fault currents in DC distribution systems, protecting solar power systems from high DC reverse currents and AC feedback from inverter failures, ensuring reliable operation.

The MG series DC molded case circuit breaker have a rated operating voltage up to DC1500V and a current rating up to 800A. At DC1500V, the MG series breakers offer a breaking capacity of up to 50kA, ensuring reliable short-circuit protection for the system. The RM3 series high-voltage DC molded case circuit breakers comply with the following standards: IEC60947-1, GB/T14048.1 (General Rules), and IEC60947-2, GB/T14048.2 (Circuit Breakers).

The MGSPD series Class C surge protector are designed for photovoltaic (PV) systems. They quickly respond within nanoseconds to divert surge overvoltage caused by lightning or other factors to the ground, protecting electrical equipment. The PJ SPD series features a pluggable design for quick module replacement. When a module fails, the indicator changes from green to red, and an alarm signal is sent to remote alarm devices via the remote signaling terminals.

The MGPV series fuses are primarily used in solar photovoltaic (PV) power generation DC combiner boxes to interrupt overcurrent and short-circuit currents that may result from current feedback from solar panels and inverters, thereby protecting the solar PV modules. These fuses can also be optionally used in any other DC circuits to provide overcurrent and short-circuit protection for electrical components.

The ELR2 series DC isolator switch, housed in a plastic enclosure, are suitable for residential or commercial photovoltaic (PV) systems ranging from 1 to 20KW and are installed between the PV modules and the inverter. With an arc time of less than 8ms, they enhance the safety of solar systems. Our products are made from high-quality components and can handle a maximum voltage of up to 1200VDC.
