WarrantyNEVER connect the solar panel array to the controller without a battery. Battery must be connected first. This may cause a dangerous occurrence where the controller would experience a high open circuit voltage at the terminals. • Ensure input voltage does not exceed 50 VDC to prevent permanent damage. Use the Open Circuit (Voc) to make sure the voltage does not exceed this value when connecting panels together in series. • The charge controller should be installed indoors in a well-ventilated, cool, and dry environment. • Do NOT allow water to enter the controller.
