Injection & Witness Testing


An injection test, or witness test, assesses the efficiency of your solar PV system’s circuit breakers by connecting a unit to the system and testing different strengths of accelerated currents.

All commercial solar installations greater than 30kW AC require secondary protection to ensure they are safe and compliant. As protection experts, we can liaise with the DNSP, test the relay and organise the site commissioning.

We provide injection & witness testing throughout Victoria and co-ordination of testing with partners in other states.
