This comprehensive kit is designed to operate single swing gates. This product features an upgraded 20W solar panel with 24V fast operating speed and longer service life. No grid connection is required, it's completely stand alone. Also with its stainless steel design, it can power tough gates weighing up to 350kg, measuring between 1.6m to 4.2m. That's a lot of power in a little package - not to mention it's weatherproof too!
