BCJ Controls Grid Protection Units
What is Secondary Protection?
Secondary protection is the protection after the solar inverter and before the grid. It is comparable to Primary Protection, which is within the inverter. Secondary protection is generally used where the installation is greater than 30kW and often includes Anti-Islanding protection, over/under voltage, over/under current and frequency protection.
Protection Units for 30kW+ Solar
The utility (or DNSP) will normally specify extra protection for installations over 30kW. Our Secondary Protection Units reflect the requirements of the DSNPs when connecting to the grid.
Our control and protection boards can offer the following features:
Solar Protection Relay
Export Allowed
Some DNSPs may allow you to export as much power as you want to the grid. Here you have to have the minimum standard of relay to protect the power quality being exported. For these applications a relay such as the ComAp MainsPro is suitable.
Zero Export
Some DNSPs limit the amount of power that you can export onto the grid. As well as power quality protection, they require that the solar system has protection so that it doesn't export more power than allowed. Here we use a relay such as the ComAp InteliPro.
