It features 4 pre-wired string inputs with 15A fuses, a 50A air circuit breaker for short-circuit protection, and an integrated surge protective device to guard against lightning strikes. Its robust build and weatherproof design ensure reliable outdoor use, while simplifying system maintenance and boosting overall solar power output.

## 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.

Review: The PowGrow PV Combiner Box is very well-made and durable. I always look for features such as ample inner spacing for components and connections. These are more expensive but also easier to maintain/or upgrade. They allow for better heat dissipation. Metal is just my personal choice, although some of the PEP types are quality units but just not as good as the steel especially when it comes to a truly solid surface mount. PowGrow has weather strip, tight closure with robust latch and hinges.
Review: Well built combiner box but I still have to install and see if it works

## 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 4pcs 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.
- 50A 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.
