GridSafe solar network protection relay boards are made by installers, for installers.


Plug and play

All our mainspro solar protection relays are pre-programmed to meet DNSP or AS4777 requirements, making them a simple and effective plug and play solution.

Complete protection

Whether it is over-voltage, under-voltage or ROCOF, our programmable mainspro protection relays will trip and protect the system quickly and effectively - in just milliseconds in some cases.

Tried & tested

When you choose an off-the-shelf solution, or one custom-designed to meet the specifics of your site, Greenwood delivers quality PV industry products trusted by installers.

Installer support

All of our GridSafe products are backed with ongoing technical support - our phone line is always open.
Our story

Protecting the grid and your hard work.

When the electrical standards for grid connected PV systems changed the industry changed and Greenwood needed to adapt. Instead of buying products from electrical switchboard manufacturers that weren’t fit for our industry, we decided to make our own. It wasn’t easy, but we persisted and created GridSafe.

After selling thousands of GridSafe network protection boards around Australia and New Zealand, we know what our sector needs and the level of quality required.
