Product Description

Product Description
SOLAR BOX Application: Combiner Box provides a means of combining multiple source circuits from a PV array into a single DC output. Each source circuit is fused separately using a touch-safe fuse holder. The combiner box allows for fail-safe operation of the system in the unlikely event that a problem with a source circuit leads to abnormally high current. In addition, the combiner box provides a convenient means of accessing the DC portion of a PV system for routine maintenance and troubleshooting.

Product FAQ
FAQ Diagram
What is the primary role of the DC Combiner Box in a Solar PV system?
The DC Combiner Box combines multiple source circuits from solar arrays into a single DC output. It streamlines wiring, provides individual string fusion, and protects the system from overcurrent or lighting surges.
Can this combiner box be installed outdoors in harsh conditions?
Yes, the combiner box is made of highly durable, non-conductive PVC material. With an IP65 protection rating, it is dustproof, waterproof, and designed to endure outdoor installations.
What safety mechanisms are built into this combiner box?
It integrates a touch-safe fuse holder for each string (15A default), II-grade surge protection (SPD) with plug-and-push modules, and a 600V 2P DC circuit breaker (63A) to isolate outputs safely.
How does the plug-and-push module design benefit maintenance?
The plug-and-push structure for components like the SPD makes replacement and troubleshooting straightforward. Modules can be swapped without rewiring the entire unit, minimizing system downtime.
What are the operation temperature limits of this unit?
This solar combiner box functions reliably across a wide operating temperature range of -25°C to +60°C, making it stable under freezing or high-temperature conditions.
