The adapter set serves as terminal of the PV generator or the DC cable of the PV generator to a Sunny Boy or a Sunny Mini Central. It consists of a cable with plus and minus adapter as well as a sealing cap. The set is available for plug connectors from Multi-Contact (old and new styles) as well as from Tyco.

The Electronic Solar Switch circuit-breaker separates the inverter safely from the PV generator. It operates in grid-feeding mode absolutely loss-free and impedes direct contact with the plug connector. Thus it guarantees the highest operational safety in all installation and maintenance work.

The ESS is integrated into the inverter . Thus, extra cabling work for the inclusion of a DC circuit-breaker during the installation of a PV system is not required.

Whether for planning a new PV plant or for the expansion of an existing plant communication: plant yields can be continuously monitored with the SMA communications interfaces. From the Piggy Back to the Data Module - cable connected or with wireless Bluetooth^® technology - SMA offers a self-developed communication system with a multitude of robust interfaces from the industrial area of application.

Subsequent expansions are possible without problem thanks to the modular design principle.

The Power Module is useful when there are no plug sockets within reach. It allows for the power supply of a device (e.g. the SMA Bluetooth Repeater or the SMA Bluetooth Power Injector) via the internal voltage supply of the SMA inverter. The Data Module type is necessary as communications connection to the inverter.

The optional communication interfaces from Sunny Boy and Sunny Mini Central can be pre-assembled with the plug-socket combination . That relieves you of a subsequent installation of the communications system. The termination resistor can be integrated into the plug.

It can be necessary when using thin-layer modules and back-to-back cells to ground the positive or negative terminal of the PV generator. With the grounding set we offer the optimal solution for this.

The grounding set offers the following advantages:

• The set is available for both the positive and negative grounding.
• Due to the internal grounding, changes to the external generator cabling is superfluous and saves time.
• The grounding is fused by an internal thermal fuse and therefore provides additional safety (fire protection).
• With the grounding set they can be seamlessly integrated into the inverter. Thus the isolation monitoring remains completely preserved. This important safety feature of SMA devices can identify possible insulation failures within the generator.

Your module manufacturer provides you on request with up-to-date information on the necessity and type of grounding.

Whether commissioning or in service - with the USB service interface you can quickly and easily either sort the inverter data or change it. It is equipped with a USB Piggy-Back for the inverter and a USB plug for connection to a PC or laptop. The USB service interface is suitable for Sunny Boys and Sunny Mini Centrals.

Detailed system control: The Sunny String Monitor monitors the PV generator by measuring and comparing individual string currents. Thus performance reductions will be safely recognized and be analyzed via Sunny Central Control. Delivered in a housing for wall mounting (IP65).

Profitable alternative to the Master-Slave concept. Sunny Central Team increases not only the energy yield, but also the reliability of systems with several inverters. Since with Sunny Central Team, only those inverters are active that are necessary for feeding the present level of solar energy into the grid. This significantly improves efficiency, particularly under partial load. Applicable for two identical Sunny Centrals.

The Sunny Central Control data logger is integrated into all Sunny Central inverters as standard. It enables detailed data recording and evaluation. All important inverter data can be displayed on the 4-line display and stored in the internal memory.
