SUNNYWEBBBOX-11-AT refurbished data logger for up to 25 inverters

SMA Sunny WebBox Refurbished: Centralised Monitoring for PV Installations

The SUNNYWEBBOX-11-AT is a data logger from SMA's product range, designed to aggregate production data and manage communication between SMA inverters and monitoring platforms. This refurbished unit has been tested and verified prior to dispatch, making it a reliable option for maintenance, repair, or system replacement projects.

Compatibility and Monitoring Capacity

The Sunny WebBox is compatible with SMA inverters communicating via the SMA Data protocol. It supports up to 25 inverters connected simultaneously, making it suitable for larger residential installations as well as small to medium commercial or industrial PV systems.

Network connectivity is provided via an Ethernet interface, enabling access to production data through a standard web browser or via the SMA Sunny Portal. Collected data includes generated power, daily and historical yield figures, as well as events and alarms reported by connected inverters.

A Refurbished Unit for Maintenance and Replacement

Choosing a refurbished data logger offers practical advantages in both preventive and corrective maintenance scenarios:

• Like-for-like replacement of a faulty Sunny WebBox without altering the existing monitoring architecture
• Reduced acquisition cost compared to a new unit
• Fast recommissioning thanks to native compatibility with the SMA ecosystem
• Contribution to circular economy principles by extending the operational life of functional equipment

Who Is This Product For?

The refurbished SUNNYWEBBOX-11-AT is primarily intended for professional PV installers managing fleets of SMA inverters, maintenance technicians working on existing installations, and site managers looking to restore functional monitoring at a reduced cost.

It is also suitable for private owners of multi-inverter SMA systems who need to replace a non-functioning data logger without investing in an entirely new monitoring solution.
