ABB have released a WiFi logging card capable of providing both residential and commercial logging for both new and old string inverters. The VSN300 is an expansion card which brings the inverter online allowing access by app or a standard web browser. The data can be accessed remotely and logs data for later analysis.
Included is MODBUS TCP functionality for linking other energy devices or string inverters (integration required).
ABB Aurora's WiFi Logger features high speed data sampling at average rates of 1 minute and will log data for 30 days at 15 minute intervals. Data is viewed through ABB's Aurora Vision platform.
The monitoring unit is also capable of changing inverter parameters which may facilitate grid power management at a later date.
Ecoelectric can supply and install VSN300 WiFi cards into both new and old solar inverters.
