Products

We produce and sell PV products such as PV combiner boxes, PV connectors, SPDs, PV fuses, PV transfer switches, etc.

PV MCCB

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).

PV Surge Protector

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.

PV Fuse

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.

PV Isolator Switch

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.

PV Grid-Connected Cabinet-Three-Phase

The primary function of the pv grid-connected cabinet is to integrate distributed energy sources such as photovoltaics and wind power into the main grid. During grid operation, it effectively balances the power load and enhances the stability and safety of the grid. As a crucial device for supplying power from the power station to the transmission line, the pv grid-connected cabinet holds significant importance in the power system.

PV Grid-Connected Box-Three-Phase

Working principle of this three-phase grid-connected box is to convert the generated direct current (DC) into three-phase alternating current (AC) that is synchronized with the three-phase power grid and then integrate it into the grid. The three-phase grid-connected box uses a three-phase inverter, which can handle higher power and more complex loads. It is mainly used in factories, large buildings, commercial centers, and similar locations.
