Description

Product Description
The 12kW single phase AC combiner box is designed for high demand residential, estate, and light commercial solar or backup power installations where large inverter capacity requires robust and reliable AC distribution and protection. It provides a secure interface between the inverter output and the main electrical distribution board.

The unit integrates essential safety components including circuit breakers, earth leakage protection, and surge protection devices. These components protect the system from overloads, short circuits, earth faults, and transient voltage surges caused by lightning or grid disturbances, ensuring long term system reliability and compliance with electrical standards.

Suitable for hybrid and grid tied inverter systems up to 12kW, the combiner box simplifies installation by consolidating all required AC protection into a single enclosure. Its durable construction allows for indoor or outdoor installation depending on enclosure rating, making it suitable for large residential properties, estates, and small commercial applications.
