The Sunny WebBox is the ideal monitoring solution for medium-sized PV plants. It receives and stores current measured values and transmits data via RS485. This means you can stay updated on the status of your plant around the clock. In the event of a problem, you can react quickly and secure your yields. Parameters can be changed and a variety of measured values can be depicted, analyzed and downloaded via a web browser. All data from the connected devices is stored and automatically transmitted to Sunny Portal, if desired. The Sunny WebBox allows central access to your plant data on the Internet via Sunny Portal.

With firmware 1.52 information of the following devices is available via the standardized Modbus interface (updated or newly added):
Information:
Version 1.51 (August 2010)
Performance Features:
Performance improvements – Data transmission via the analog and GSM modem, SD card access and web interface response are considerably faster.
Modbus data interface – To query inverter data. Further information can be found in the Modbus profile description in the download area.
Sunny Central firmware updates – The Sunny Central firmware can be updated via the web interface of the Sunny WebBox, thus avoiding servicing on-site.
Simplified device exchange – As of now, the deletion of both the portal buffer and the channel list, which is necessary during device exchanges, can also be done at the "Installer" access level.
Simplified error analysis – Error codes are shown on the web interface with an error description and information on error elimination.
Support of new device types – Updates for the devices supported; device types to follow can be loaded using an SD card.
If you have deactivated the Sunny WebBox's automatic firmware update, you can carry out the update manually using your Sunny WebBox's web interface.
Note: if your Sunny WebBox is connected via an analog modem, it is impossible to carry out an update from firmware 1.50 to firmware 1.51 via the modem. Instead, you can download the firmware from the download area (from September 1, 2010) and update your Sunny WebBox using an SD card.
