The Adaptor Set serves as connector 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 adaptor as well as a seal. The Set is available for plug connectors from Multi-Contact (old and new styles) as well as 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 cable work for the inclusion of a DC circuit-breaker during the construction of a PV system is not required.

SMA has specially developed a communication system for quick and easy inspection of PV systems. The Piggy Backs are individually formulated to the modular design principle. Subsequent extensions are possible trouble free.

Not compatible with SUNNY BOY 3000TL / 4000TL / 5000TL.

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

Not compatible with SUNNY BOY 3000TL / 4000TL / 5000TL.

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

The Grounding Set offers the following advantages:

• The set is available for both the positive and also negative grounding.
• Due to the internal grounding, changing the external generator cabling is not required which 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 can provide you 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.

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, then the varistors will be destroyed. Replacement is simple and possible at all times. We include the dedicated tool in the delivery.

Our Wireless-Set enables the contact between two components of a PV system via RS485 without any cables. It is used anywhere where it is impossible to lay cables. Obstacles such as streets, railway tracks or rivers can be easily overcome - without any problems. The Wireless-Set is pre-configured, easy to install and has a range of up to 500 meters in the open field.

For the construction of large PV power stations: You require the Sunny Main Box for DC distribution for system developments with Sunny Central 1000MV. They come with the IP 65 protection system and connection possibilities for up to 8 Sunny String Monitors or Sunny String Boxes.

You position the Sunny Main Box between the Sunny String Monitor and the Sunny Central.

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) or as standard distributor Sunny String Monitor-Cabinet (IP 54).

Profitable alternative to the Master-Slave concept. Sunny Central Team increases not only the energy yield, but also the availability of systems with several inverters. Since with Sunny Central Team, only inverters active are those 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.

More comfort: The connection terminal blocks enables you a clearly understandable wiring of the digital and analog inputs and outputs on the Sunny Boy Control Plus.
