8 Ways DC Combiner Box With SPD for Photovoltaic System

 The only supplier have the testing equipment in following aspects:

• Inner resistance: to keep each string has the same innner resistance

• Withstand voltage: to test whether the finished products meet the withstand voltage standard

• Temperature rise test:  to imitate the practical environment and then test the temperature rise to keep the normal and stable quality of the finished products

Benefits

• Wide range DC input, the maximum open circuit voltage reaches 1000VDC
• Remote monitor, RS485 communication optional
• Simplify PV system wiring
• Comply with the requirement of outdoor installation
• PV only DC fuse
• PV only SPD
• Customized on customer's demand
