I have just fitted n 80 W solar panel with a controller as shown in the picture below. The controller has four LEDs, three on the left hand side and a single LED on the right hand side. The three left hand side LEDs act as follows (I believe): the left hand LED shows green when the solar panel is connected, the middle LED deals with the battery condition and the right hand LED deal with any load directly taken from the controller. In my set-up there are no loads connected directly to the controller, all loads are taken from the batteries (2 x 100 Ahour) The single LED on the right hand side of the controller appears to be an off LED as it is near a switch. Unfortunately I have lost the instructions so I do not know exactly what the LEDs are telling me. :Sad: At present the left hand LED (of the three) is solid green, the middle LED is flashing green (batteries are fully charged!) and the third LED is off (no load!) The LED on the right hand side is solid red. Can anyone please confirm the meaning of the LEDs and, if possible. let me know where I can get a copy of the instructions?
