ABB introduces advanced Arc Fault Circuit Protection for PV systems

2012-09-25 - ABB, in conjunction with Shoals Technologies, demonstrates its Arc Fault Circuit Protection solution at the Solar Power International event, utilizing the latest in insulation monitoring technology to prevent fires and explosions.

Orlando, FL, September 25, 2012 – ABB, the solar industry’s leading power technology provider, is demonstrating its new Arc Fault Circuit Protection solution at the Solar Power International conference and exhibition last week, in conjunction with Shoals Technologies Group.

This solution uses new and advanced insulation monitoring technology to detect a system fault and prevent an arc flash incident before it happens. This type of detection system assures an alert for any potential fault, and can be adjusted for both small combiner and larger PV systems. It also provides visual status indication that can be connected to a PLC for remote monitoring.
"The main purpose of Arc Fault detection is to detect and prevent a fault that may eventually cause a fire,” said Allen Austin, Global Segment Manager for Solar Power, ABB Low Voltage Products Division. “The ABB system approach is to monitor the system and advise of system malfunction well before an incident occurs. This will not only prevent a fire caused by an arc but it will also prevent equipment damage that can occur after an arc fault is detected.”

Shoals Technologies Group, a Portland, Tennessee-based producer of combiner boxes and other advanced PV products, has fully integrated this system in its new state-of-the-art combiner box design. It also incorporates circuit protection technology using a moulded case circuit breaker instead of a usual disconnect.” Not only does this system provide arc fault protection, it also provides short circuit protection, ensuring the ultimate in people and equipment protection,” said Dean Solon, CEO of Shoals Technologies Group.

ABB ( is a leader in power and automation technologies that enable utility and industry customers to improve performance while lowering environmental impact. The ABB Group of companies operates in around 100 countries and employs about 145,000 people. The company's North American operations, headquartered in Cary, North Carolina, employ over 27,000 people in multiple manufacturing, service and other major facilities.
