Description

Product Description
The 16kW three phase AC combiner box is designed for larger residential estates, commercial buildings, and light industrial solar or backup power systems where a three phase inverter requires reliable and compliant AC distribution. It provides a central interface between the inverter output and the main distribution board, ensuring safe operation and efficient power delivery across all phases.

The unit incorporates essential protection components including three phase circuit breakers, earth leakage protection devices, and surge protection devices. These components protect against overloads, short circuits, phase imbalance, earth faults, and voltage surges caused by lightning or grid disturbances, ensuring system reliability and safety.

Suitable for three phase hybrid and grid tied inverter systems up to 16kW, the combiner box simplifies installation by integrating all required AC protection into a single enclosure. Its robust and weather resistant design allows for indoor or outdoor installation depending on enclosure rating, making it suitable for demanding residential, commercial, and light industrial applications.
