Feature of 6 String PV Combiner Box
- Professional PV combiner box is suitable for your Photovoltaic On/Off-Grid Solar Power Generation Systems, which makes your solar panel system work reliably and safely. With multifunction: PV array input with first-class combination, Quickly cut off circuit, anti-thunder protection, anti-reverse, overload, etc.
- Metal box with a lock. Waterproof class: IP65. A durable metal box makes it much more suitable for outside use and installation. It has a longer lasting time than the PVC plastic solar combiner box. The internal mount plate is also made of metal.
- High-quality wires. All wires are pre-wired in the box. Our solar combiner box uses professional wires that are especially for solar systems. Built-in with a ground wire connector, the ground wire installation is available. Please ensure the current and voltage of a single PV array don’t exceed 10A/250VDC. Then you can connect the solar panel to the combiner box.
- Built-in with 6pcs individual 15A rated fuse(10x38mm). The maximum current of a single PV input array is 10A. Their function is overload protection. The Combiner Box protects PV solar panels and inverters. Besides it will reduce the length of the cable connection from the panel to the inverter, optimize system instruction make the system more useful and maintenance. All in all. It will make the PV power system increase output power.
- 63A air circuit breaker. It can provide short circuit fault protection and control the combiner box output. Here is a Surge Protective Device/Lighting Arrester that provides lightning protection. The “Green” indicates Normal, once it changes into “Red”. Remember to replace the SPD with a new one.
