Is it normal that the public grid charges the batteries all the time?

If the batteries are permanently charged by the public electricity distribution network it is because the IMEON has been programmed to work in this way.

To change this parameter, connect to the IMEON OS. ONE. In the “battery” tab menu you can disable or enable battery charging by the network. If you allow it, you must program a time slot during which the batteries will be charged by the network. Please note, if you program the time slot from 00:00 to 00:00, the batteries will be permanently charged by the network.
