## Overview

The PowGrow PV Combiner Box is a heavy-duty, IP65-rated metal enclosure designed for on/off grid solar systems. Featuring 4 pre-wired 15A fuses and a 50A air circuit breaker, it provides comprehensive overload, surge, and short-circuit protection. Its durable construction and integrated grounding ensure long-lasting outdoor reliability while optimizing solar panel connections for enhanced system performance and easier maintenance.

## Description

Our PV Combiner boxes are PV products designed to reduce the connection between the PV module and inverter, simplify maintenance and increase reliability. The PV Combiner Box allows you to connect a certain number of PV modules in a series with the same specification, and form a series of PV modules according to the DC voltage range of the inverter input, and connect multiple series to a PV combiner box.

## Features

- Professional PV Combiner Box is suitable for solar powered on/off grid solar power systems This ensures that your solar panel system is safe and secure. MULTI-FUNCTIONAL: First class combination PV array input, quick circuit disconnection, lightning protection, reverse,overload etc
- Metal box with lock Waterproof rating: IP65 durable metal box is suitable for outdoor use and installation. Last longer than PVC plastic solar biner boxes. The internal mounting plate is also made of metal
- High Quality Wire All wires are pre-wired in the box. Our solar biner box uses professional wire especially for solar systems. Built in ground wire connectors for grounding wire mounting. The current and voltage of a single PV array should not exceed 10A/250VDC. Then you can connect the solar panel to the biner box
- Pack of 4 15A rated fuses (10x38mm) The maximum current of a single PV input array is 10A. Function is overload protection. Combiner box protects PV solar panels and inverters. Not only does it shorten the cable connection length from the panel to the inverter, but the system optimizing instructions make your system more convenient and maintainable. EVERYTHING! This allows the PV power system to increase the output power
- 50A Air Circuit Breaker Provides short-circuit failure protection and controls the combination box output. This is a surge protection device/lightning arsenor. "Green" indicates normal and turns to "red" once Remember to replace SPD with a new one
