Refined and 4-String Solar Combiner Box with Fuse, Surge Protector, and Circuit Breaker for On/Grid and Off-Grid Solar Panel Systems

Revised Content:

Our PV Combiner Box is a device engineered to streamline the connection between PV modules and inverters, facilitating maintenance and enhancing reliability. Users can connect a specified number of PV modules with matching specifications in series, forming a PV module array that aligns with the DC voltage range of the inverter input, and then connect these series to the PV Combiner Box.

The combiner box comes pre-wired, utilizing professional solar-specific wires that are more durable than standard wires. The box is equipped with a 15A Rated Current Fuse, a Surge Protective Device, and a 50A Air Circuit Breaker, along with a ground wire connector to enable simple ground wire installation.

The 4 individual 15A rated fuses (10x38mm) provide overload protection, with a maximum current of 10A per single PV input array. The Air Circuit Breaker offers short-circuit fault protection and controls the combiner box output, enhancing the system's reliability and safety through its anti-circuit protection function.

The Surge Protective Device offers lightning protection for both positive and negative poles, with a "Green" indicator light that turns "Red" when replacement is required. The anti-rust lock with keys secures the box, preventing unauthorized access.

Constructed with a durable metal housing, the combiner box is well-suited for outdoor use and installation, boasting a longer lifespan compared to PVC plastic solar combiner boxes. The internal mount plate is also made of metal, and the design incorporates heat insulation devices between the Fuse Holder, SPD, and Circuit Breaker to improve heat dissipation.

The DIN rail mount allows for easy installation and replacement of the Fuse Holder, SPD, and Circuit Breaker components, ensuring a safe and reliable setup. Ultimately, the PV Combiner Box is designed to optimize your Photovoltaic On/Off-Grid Solar Power Generation System, enhancing its reliability, safety, and power output.
