Powerline Adapters enable transmission of data via the electricity cables in the building. There are always at least two Powerline Adapters in the building: One is connected to the solar inverter via a network cable, and the other one is connected to the router via a network cable. The data from the inverter are sent to the electricity cables via one Powerline Adapter. The other Powerline Adapter receives this data from the electricity cables and passes it on to the router. Powerline Adapters are a smart way to create a cabled communication without having to pull new network cables through a house.
