MSG-PV4/1 combiner box is suitable for inverter (MAX input voltage DC1500V, 4 PV input channel, 1 output channel, single MPPT inverter). Box body is made of PVC engineering materials, with test for fire retardant, temperature rise, anti impact, anti ultraviolet,and other testing. IP65 protection grade.The combiner box is a device for collecting current. It is mainly used in large and medium-sized photovoltaic systems. The number of components in the PV array is large and the output is large. It is necessary to have a device to concentrate these outputs so that they can be directly connected to the inverter.
1. It can disconnect circuit breaker automatically with function of fault identification. 2. High accuracy of current-sampling without influence of temperature and power supply voltage. 3. Combiner box provides power supply itself. 4. It uses Rs485/MODBUS-RTU communications and make local monitoring parameters.
1) Photovoltaic battery open circuit alarm, status detection
2) With switch input, used to collect DC circuit breaker, lightning arrester and other output empty contact status
3) With relay output, it can be set to jog mode, used to drive the automatic opening and closing of DC circuit breaker
4) Provide sensor input interfaces such as temperature, irradiation, and wind speed
5) It can output DC24V power supply to supply power to external sensor
6) The local digital tube cyclically displays the input current of each channel and has an automatic shutdown energy-saving display mode.
