The TIGO Rapid Shutdown Kit is designed to complement our OMO 150KW Solar Kits. Increasingly, municipalities are requiring rapid shutdown systems be deployed as a part of rooftop solar arrays. Please check your local regulations and discuss this option with an OMO Technical Expert to determine if this system is required on your particular application. This system includes the required number of TS4-A-F (Fire Safety) advanced add-on rapid shutdown modules and RSS Transmitter kits required for your OMO Solar System. This kit provides a small discount off the cost of individual components. As a bonus, if you add a Rapid Shutdown Kit to one of our solar kits you'll receive an additional 10% discount off this package!
