Solar panel safety relay address de-energising challenge

Addressing the challenge of de-energising solar PV panels and other renewable energy sources, Omron launches a high power DC relay, capable of rapidly interrupting 25A at 1000V DC in the event of an emergency.

The G7L-X relay has a rated load of 1000V DC at 25A and a release time of just 30ms.

As rooftop solar panels become increasingly popular, rapid PV shut-down is becoming mandatory in some markets in order to protect fire fighters and other first responders. The relay can be installed close to a PV panel or other renewable source, and disconnected quickly in an emergency, to allow maintenance or in response to utility requests. The G7L-X conforms to UK and IEC solar inverter standards, as well as applicable UL and VDE electrical standards.

The design includes an assisting magnetism circuit, to help achieve a very quick switchover. The relay contacts have been specifically designed to handle the high DC loads, and have a contact gap of 6.0mm for safety.

The G7L-X is rated at 6,000 operations at 600V DC, and 100 operations at 1,000V DC, more than enough for emergency cut-off applications, says the company. It measures just 52.5 x 35.5 x 41.0mm and can be used for outdoor installations. It operates in ambient temperatures of between -40 and +85 degree C. A general purpose version of the relay has a capacity of 20A at 1,000V DC.
