Connecting the Device
8.10 GPRSconnection(optional)
The hybrid inverter has a GPRS (radio frequency) interface
that is used to control the switching time of a designated load
via the external smart plug (not included in the scope of delivery),
so that the load mainly consumes PV energy and incurs the lowest
possible energy costs during operation.
