A notice:

1. When multiple solar modules are connected as a group in series or parallel, make sure that the open circuit voltage (Voc) and short circuit current (Isc) of a single circuit do not exceed the maximum input voltage (60V) and maximum input current (16A).


2. In standard mode, when the battery level of Vitapower is below 95%, the PV panel will give priority to charging the Vitapower. When the battery level is above 95%, the PV panel will supply power to the household.


3. When Vitapower is connected to a household socket, the AC output will not work.


4. If you want to charge the Vitapower with household current, please first change the settings in the app to “Charging mode”.
