LCD Operating interface description : 1.Ready installation tools and materials,and cable.Please matching suitable cable2.Ensure that the current desity<4A/mm2 That will help reduce the line pressure drop.check the installation site meets the relevant safety requirements,avoid damp,dusty,flammable,explosive and corrosive gases3.Install the controller fixed to the vertical plane,see Section V mounting aperture and hole spacing.In order to ensure a good controller cooling conditions,the controller on the bottom of each reserved 10cm space 4.As shown on the right wiring sequense:load,battery,solar Battery plate is connected to the controller to be taken to ensure that the load,battery,The polarity of the solar cell panel and controller5. Before use:external temperature sensor probe into the left of the controller temperature probe interface probe placed in similar battery temperature.(Line extensive must be build-in devices of the external temperature probe coextensive Otherwise,the controller will control parameters of the temperature compensation of the error6.Warning:In order to prevent accidents from occurring,install:non-professionals can not be engaged in loading and unloading operationsProblem Solution No proper installation of solar panels cable polarity("+""-") Removing the polarity,you can re-install the correct More than the rated power of solar panels to reduce solar panel power does not exceed the rated power controller discharge Problem Solution Removing the load is not properly connected to the load,re-install the correct More than the rated load power to reduce load power,the controller does not exceed the rated power
