The primary function of the storm kit is to protect the condenser in the case of electrical surges, strikes, voltage drops or spikes, or storms. It includes a hard start kit and a surge protection device
The hard start is installed off the main capacitor for the system, the surge protector is installed on the main power disconnect of the system, or, inside the condenser panel, and has an indicator light on it (green) to show you that it is working and your equipment is protected
One time installation, no on going maintenance or additional costs needed for full protection
