Solar Panel Charging The solar panel absorbs solar energy and charges the 12-volt battery (not included). The gate opener then runs off this charged battery. The solar panel can be installed up to 250 feet away from the control box and charge controller.One Power Supply for Simplicity One major benefit of the Estate Swing Solar series is that it uses a single power supply to connect to the control board. Fewer wires mean simpler installation and easier use. It also offers better protection against power surges. With reduced wiring and the lowest standby draw on the DIY market, the Estate Swing Solar series truly stands apart.No Learning Procedure This is one of the most desirable features of this intelligent control board. Once everything is wired, you can simply run your gate opener. Other openers require a learning procedure to determine run times and other settings. Not with this opener, no hassle involved.Easy Access Adjustable Magnetic Limit Switches There are many advantages to the limit switches on this unit. They are easy to adjust and access. Located at the bottom of the arm's exterior, simply slide them to the desired location and tighten the screw. Both the open and closed positions are adjustable, offering more flexibility in stopping points after the brackets are bolted into place. Additionally, the magnetic switches eliminate components that can wear out or break due to contact.Adjustable Run Time/Soft Stop One of the parameters you can set for this opener is the run time. The advantage of this feature is that it's not a learned procedure, but rather an adjustment you manually input for a customized soft stop.
