Operating State Solar Controller
(Sun Symbol):
Depending on the solar controller, the operating state of the solar controller is indicated by the sun symbol.
No sun: Solar power is not at disposal; the solar controller is in stand-by mode.
Full sun: Solar power is at disposal, maximum possible charge
Flashing sun: The controller limits the current because of a full or almost full battery to avoid battery
overcharging. For determination of the possible solar power, the battery must be discharged by a consumer
(such as lighting) until the solar controller supplies full power, and the sun symbol stops flashing.
Function of Votronic controllers MPP 150, MPP 225, MPP 320, MPP 324, MPP 484:
No sun: Solar power is not at disposal; the solar controller is in stand-by mode.
Flashing sun: Proper operation of the controller. Control to “Maximum Power Point” (MPP).
