We offer a broad range of accessories for our inverters and data communication components. From A for adapter set to Y for Y connector you will find everything here that you require for your solar power system.
Our accessories guarantee the highest technical quality and fit perfectly to your SMA device.
Adapter Set for connecting PV Strings
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.
Electronic Solar Switch (ESS)
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.
RS485 Piggy Back and Data Module for plant communication
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.
Power Module for power supply to areas that are difficult to reach
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.
Connector system for communication
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.
Not compatible with SUNNY BOY 3000TL / 4000TL / 5000TL.
Sunny Boy Grounding Set for transformer inverters.
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.
USB Service Interface
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.
Not compatible with SUNNY BOY 3000TL / 4000TL / 5000TL
Varistors protect the input port of the inverter from dangerous surge voltages. If the surge voltage is too great, the varistors will be destroyed. Replacement is simple and possible at all times. We include the appropriate tool in the delivery.
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).
SUNNY CENTRAL Team
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.
SUNNY CENTRAL CONTROL
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.
The integrated data logger, Sunny Central Control, forms the communication basis of Sunny Central devices. Here you can connect several Sunny Centrals to a switch or router, each with its own Ethernet NET Piggy-Back. Thus a central monitoring of the complete PV system is possible.
Sunny Remote Control 1
The external control unit SRC 1 enables an easy and fast commissioning of the Sunny Islands 2224 and 2012 as well as of the Sunny Backup 2200. Rotating push button and illuminated push button ensure an intuitive operation, the four-line display informs about the current system status. Saving data takes place on a SD card.
Generator manager for the automatic commissioning of power units capable of remote control which need more than one starting contact. Different commissioning procedures, preheating and power-down times are selectable.
Compatible with Sunny Islands 5048, 4248, 3324, 2224 and 2012.

Load shedding contactor SI-LS
Load shedding contactors for the use of AC coupled islanding systems: In case of energetic overstrain of the system, recharging the battery - e.g. via the PV system - is made possible through disconnecting the loads. To ensure that the contactor does not fall off in case of a short circuit, solely DC contactors are used which are supplied by the battery.
We offer various load shedding contactors for currents of 25, 40, 65 and 95 A as well as for voltages of 48 and 24 V.
Compatible versions are available for alls Sunny Islands.
