These cords can be used to connect multiple SolarStorm systems together, allowing them all to be powered from the same outlet, using a single controller.

Maximum number of connected systems:

• 10 SolarStorm 220 LED grow light units 
• 20 SolarStorm 110 LED grow light units 

Note: The piggy back chaining cord only works with SolarStorm 110 and SolarStorm 220 systems.
