How to connect a GSD to a SolarEdge Inverter

Installing a GSD (Generation Signalling Device) on an SolarEdge inverter system to meet the new Queensland Emergency Backstop requirements is simple 3 step process:


1- Mount the GSD in a suitable location – i.e. within the MSB or the switchboard containing the protective device for inverter supply.
If using a network protection AC Board (supplied by AC Solar Warehouse) this can be pre-wired with a GSD on request.


2- Connect AC power to the GSD by wiring it directly to the Main Switch Inverter Supply.


3- Connect the GSD control cable to the SolarEdge inverter’s PRI (power reduction interface) port on connector pins 5 and 6 via the RJ45 adapter that is supplied with the GSD.


SolarEdge has released an App Note providing detailed instructions on connecting a GSD to SolarEdge systems . Check out the guide here.


You can also reference our recently published article on the Queensland GSD requirements for more details.
