The Gateway is needed for a connection to Delta's SOLIVIA Monitor 2.0 monitoring web portal. It transmits statistics data and messages about the operating behavior from the inverters of the PV plant to the web portal.
Control of Asymmetric Grid Load
The Gateway can be used to control asymmetric grid load. An asymmetric grid load can occur when 1-phase inverters are connected in 3-phase grid. In some countries limits for the asymmetric grid load are defined, e.g. 4.6 kW in Germany.
The gateway monitors the grid load and regulates the feed-in of the inverters in case of a not allowed aymmetric grid load.
Connection to Ripple Control Receiver
Via the Gateway, the inverters of a PV plant can be connected to a ripple control receiver which is mandatory in Germany for PV plants larger than 30 kW.
