## Description

Our PV Combiner Box is a PV product designed to reduce the connection line between PV modules and inverter, facilitate maintenance and improve reliability. Using PV Combiner Box, users can connect a certain number of PV modules with the same specifications in series to form a series of PV modules according to the DC voltage range of the inverter input, then connect several series to the PV Combiner Box.Features 1.Equipped with high-voltage fuse and circuit breaker for two levels of safety protection. Multiple PV array input Max current of single PV input array is 10A. Built in with 6pcs individual 15A rated fuse. Their function is over load protection. 2.Install with professional high voltage lightning arrester, both positive and negative poles with anti-thunder protection function. 3.Professional high voltage Air Circuit Breaker controls output, with anti-circuit protection function which makes the system more reliable and safety. 4.The wires are pre-wired in the box. They are used with high quality wires especially for solar system. 5.There are Heat Insulation Devices between Fuse Holder, SPD and Circuit Breaker. Increased the installation distance between them. To improve the heat dissipation effect.6.A waterproof and anti-rust lock is installed on the box to prevent others from opening the combiner box.Technical Parameters Max. Input current of single PV array:10A Total input current of PV array:60A Max. Input voltage of single PV array:400DCV Max. Output power voltage:400DCV Working temperature: -22℉～158℉(-30℃～+70℃) Working humidity:0-95% Surge Protective Device：In: 20kA；Imax: 40kA；Up: 2.2k SPD Indicate light status:Green: Normal; Red: Triggered Air circuit breaker parameter: 500V, 63A; ON/OFF Fuse parameter: DC1000V, 15A Fuse holder parameter:DC1000V, 20A Waterproof:IP65 Dimensions(LWH):13x11x5 inch Item weight: 5.2kg

## Features

- 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 safety. 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. 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 is used professional wires that are especially for solar system. Built-in with a ground wire connector, the ground wire installation is available. Please ensure the current and voltage of single PV array doesn’t exceed 10A/250VDC. Then you can connect solar panel to the combiner box
- Built in with 6pcs individual 15A rated fuse(10x38mm). Max current of single PV input array is 10A. Their function is over load protection. The Combiner Box protects PV solar panel and inverter. Besides it will reduce the length of cable connect from panel to inverter, optimize system instruction makes 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 controls the combiner box output. Here is a Surge Protective Device/Lighting Arrester provides lightning protection. The “Green” indicates Normal, once it changes into “Red”. Remember to replace the SPD with a new one.

## Questions & Answers

**Q: Is this UL rated?**
A: No I always call the customer service.

**Q: What size wire goes from the combiner strip (at top) to the breakers? #10 = 30 total amps.or #8=55amps. which one?**
A: #10 30 AMP Max

**Q: Have three strings.  I need a 20 amp fuse for one of them, can I replace one of the 15 amp fuses with a 20 amp and keep the remaining fuses 15 amps?**
A: For your case, please ensure the three strings' total voltage are close or the same to each other.

**Q: My panels have 8.9Amp.Should that be protected by 10Amp fuse?**
A: This does not matter. 10Amp and 15 Amp are both can be used. We offered 15Amp.
