Description

Product Description
The 3kW single phase AC combiner box is designed for small residential solar or backup power systems where a single phase inverter requires safe connection to the load or distribution board. It acts as an interface between the inverter and the electrical system, providing essential protection and isolation.

This unit typically includes components such as circuit breakers, surge protection devices, and earth leakage protection to ensure safety against overloads, short circuits, and voltage surges. It simplifies installation by consolidating all required AC protection into a single enclosure.

The combiner box is suitable for grid tied or hybrid inverter systems up to approximately 3kW capacity. Its compact and durable design allows for easy wall mounting and reliable operation in both indoor and outdoor environments depending on enclosure rating.

It is ideal for residential installations where safety, compliance, and neat system integration are required.
