2IN2OUT -Combiner Boxes CB2IN2OUT

Product Overview

A 2IN2OUT (or CB2IN2OUT) combiner box is an electrical enclosure used in solar power systems to manage two parallel strings of solar panels. Instead of combining them into a single output, this type of box keeps the two strings separate, allowing them to connect to an inverter that has two independent Maximum Power Point Trackers (MPPTs). It simplifies wiring while providing crucial protection against electrical faults and lightning.

Key Features

• The main purpose is to simplify the wiring, taking two sets of positive and negative wires from your solar array and combining them into a single, fused output.
• It includes essential safety components, which provide protection from electrical faults that could damage the system or pose a fire risk.
• The box is typically housed in a weatherproof enclosure (often IP65 rated) that protects the internal components from dust, moisture, and other environmental factors.
