GrapeSolar APP is used as a remote display and operation panel for the relevant solar charge controller (an external or inbuilt BT module is required for usage). By operation on this APP, you can check the status of PV, battery, DC load for the solar DC charge system with charge controller.
We have 3 main pages of operations in ChargePro 2.0. The first page is for displaying the status of the system, the 2nd page is for displaying the historical data, the last page is for displaying the parameters for settings. Except for showing the present system information, we also can set the parameters for the charge controllers in the parameter setting pages, like for battery type, battery charge & discharge voltages, load mode settings and etc.
For more information, please contact the solar charge controller providers.
