Description

Product Description
The 8kW single phase AC combiner box is designed for larger residential and small commercial solar or backup power systems where higher inverter capacity requires safe and compliant AC integration. It provides a centralized point for AC protection, isolation, and distribution between the inverter output and the main electrical distribution board.

The unit integrates essential protection components such as circuit breakers, surge protection devices, and earth leakage protection to ensure system safety and reliability. These components protect against overloads, short circuits, and voltage surges caused by lightning or grid disturbances.

Suitable for hybrid and grid tied inverter systems up to 8kW, the combiner box simplifies installation by combining all required AC protection into a single enclosure. Its durable construction allows for indoor or outdoor installation depending on the enclosure rating, making it suitable for residential estates, commercial buildings, and backup systems.
