  1. Solar Protection Relay What is Solar Protection Relay?

  2. Solar Protection Relay • A Solar Protection Relayis used to connect embedded generators over 30kW to the grid. There are two main categories of Solar Protection Relays, these being Grid Protection Relays and Zero Export Relays.

  3. What is a Grid Protection Relay? • A grid protection relay, sometimes called a grid-tie or mains protection relay, is a device that ensures the power quality is acceptable  to be exported to the grid. These include under/over voltage, under/over current and frequency protection. What makes these suitable for embedded generators is the anti-islanding function in addition to power quality protection.

  4. ComAp MainsPro • ComAp MainsPro is a Solar Protection Relay with the 'Mains-Disconnect' Function.

  5. What is Anti-Islanding? • Anti-Islanding is a type of electrical protection for embedded generators such as grid connected solar, wind or diesel. It ensures the generator disconnects electrical supply to the grid in the event of a blackout. Anti-Islanding protection exists to protect personnel and equipment connected the grid in the occurrence of a fault or maintenance.

  6. ComAp InteliPro • The InteliPro is a Solar Protection Relay used for Zero Export applications.

  7. What is a Zero-Export Relay? • A zero export relay is similar to a grid protection relay as it has all of the power quality and anti-islanding protection functions. It has the added function of being able to monitor the current flowing and disconnect at a pre-set value.  This ensures the embedded generator never exceeds the maximum export value allowed by the DNSP.

  8. Power Ramping • Zero Export Relays trip the solar system when production exceeds the permitted amount. It's good practice to ramp the power down so that the site doesn't trip on days where the production may exceed load (eg. a school at the weekend).

  9. BCJ Controls • BCJ Controls - commercial solar network protection unit - switchboard manufacturing including protection relay & anti-islanding and zero export devices. BCJ Controls is a solar technology company set up by ex-utility industrial sparkies. Between them they have a large amount of experience in electrical grid protection, as well as dealing with utilities on a day-to-day basis.
