Switchboards for a smarter energy future

Turnkey Grid Protection Solutions

We design and manufacture bespoke PVDB grid protection switchboards to meet grid safety requirement.  Secondary protection for solar PV installations over 30kW are mandatory by most local power network providers.  These protection systems sit between the solar system and the electricity grid.

All our grid protection units, which cover the kW and MW range, are pre-programmed to meet reliable distributed solar energy generation, storage, and load controls for optimal grid performance.

Our engineering innovations with solar PV grid protection boards (PVDB) and mains protection relays (MainsPro) combined with our design experience  means we can guarantee to get  your installation over the line with your power network provider.  We’re proud to have shipped over 1,000 switchboard units nationwide that are creating a smarter and cleaner energy future.

Protection Boards for 30kW+ Solar

The DNSP normally requires secondary protection for installations over 30kW. Our secondary protection boards meet the requirements / standards of the DSNPs when connecting to the grid.

Our control and protection boards offer the following features:

  • Plug and Play Easy Installation
  • Mains Disconnect / Anti-Islanding Protection Function
  • Suitable for up to any number of inverter inputs
  • Powder coated IP65 enclosure
  • AC3 rating of the contactor to ensure that heat rise is within permissible limits

What Our Clients Say


This company is excellent. We go to them first for Grid Protection Units. They offer great value especially when you add their top notch customer service. As usual, we needed something STAT this week and the team didn't leave us hanging, even finishing it up and testing on a Saturday to meet our timetable. Graham Dennis shout out.
Mark Horsfall (Simmark)

Big fan of these guys - always answer the phone. They helped me out when Endeavour Energy required a neutral voltage displacement protection function on the solar installation
