Product advantages
●The protection level of the combiner box reaches IP65, which is waterproof, dustproof, rust proof and salt spray resistant, meeting the requirements for outdoor installation 
●It can simultaneously connect up to 32 battery strings;
●Each positive and negative pole of the battery string is equipped with photovoltaic dedicated fuses to protect the module string from faults. The fuse base and fuse are used together to reduce maintenance costs for the owner and effectively protect the personal safety of maintenance personnel; 
●The use of photovoltaic dedicated high-voltage lightning arrester can protect the positive pole to ground and negative pole to ground of the busbarl after junction, and the continuous working voltage (Uc) căn reach DC1500v;
●The power module inside the combiner box can be connected to a photovoltaic voltage of up to DC1500v; 
●The measurement and control module of the combiner box adopts reliable Honeywell Hall elements (DC CT sensors) to collect, monitor, alarm and locate local faults for the current and bus yoltage of each photovoltaic string. It can also measure the temperature inside the combiner box, detect the status of lightning arresters and output circuit breakers, etc; 
●The monitoring module inside the combiner box has digital display function, which can display the current of each component string, bus voltage, temperature inside the combiner box, status of circuit breaker lightning arrester, system power and equipment address on the equipment;
●Equipped with RS485/MODBUS-RTU serial communication; 
●The external interface is equipped with lightning protection; 
●It can receive parameter downloads from local monitoring devices for analysis and processing; 
●The working power supply of the combiner box can be selected from external 220VAC/DC or from the power supply provided by the combiner box itself.
If the power supply is provided by the combiner box itself, there is no need for specific power supply and separate wiring on site.
