You have acquired a high-quality product with unique features and a top efficiency level. This Solar Inverter is designed in accordance with the proven HERIC® topology and therefore guarantees you a maximum energy yield. The Solar Inverter is equipped with three independent energy units which transform the energy of three separately connected PV generators into grid-compatible AC power and inject it in three phases. Thanks to the MPP multitracking process, PV generators with various ratings can be connected to the same Solar Inverter with the NT 10000. In this user manual, you will find explanations on how to use the Sunways Solar Inverter NT 10000. It includes information on installation, commissioning, the functioning method, and system monitoring. 90 BP13370_NT_10000_englisch 1.1 23.11.2005 17:40 Uhr Safety Instructions Seite 7 General Safety Instructions The user manual contains safety instruc- All safety instructions contained in this tions.

The described product may not be operated if any mechanical or electrical component is defect. Prior to commissioning the PV system, we strongly recommend reading and observing the manual and the instructions carefully! Non-compliance may lead to serious consequences such as damage to the device, damage to other assets, personal injury, or fatal accidents. The Solar Inverter may only be installed by a trained and qualified electrician. It must be approved by the power supply company in charge. In the chapter headings, the due steps are additionally marked by the adjacent symbol. 91 GB BP13370_NT_10000_englisch ! 23.11.2005 17:40 Uhr Seite 8 Opening the Device Prior to opening the housing, always disconnect the device from the grid and the PV generator. After having been disconnected from the PV generator, there is still lethal voltage inside the device and at the PV generator hubs for approximately five minutes. It takes that long for the energy-storing capacitors to fully discharge. After having disconnected the device from the grid and the PV generator, wait at least five minutes before opening the device. 92 BP13370_NT_10000_englisch 1.2 23.11.2005 17:40 Uhr Sunways Solar Inverter NT 10000 Scope of Delivery Seite 9 Checking the Consignment Prior to shipment, our products are checked to make sure they are in a perfect con- · Sunways Solar Inverter NT 10000 dition.

The assessment of the electrical and mechanical safety and the environmental influences (foreign bodies, moisture) must follow in the installed condition in the overall PV system. In the installed condition, the EMC characteristics of this product can change. Therefore for the overall PV system, a check of the EMC characteristics through the final product manufacturer is practical. Changes reserved. The currently valid issue is available upon request.

The installation instructions in the technical documents are to be observed. The checks follow for an installation, which is typical for the system on a measuring station, which conforms to the norms. The legal requirements for the stability and the emitted interference, limit values and norms are listed in the documentation named above. The Sunways products are intended for the installation in a PV system. The check results are not transferable in all cases to the installed condition in the PV system. This declaration therefore does not contain the assurance of EMC characteristics of the final product. Changes reserved. The currently valid issue is available upon request.

In particular, the directives for connection and parallel operation of in-plant generation systems to the low-voltage grid of the energy supply company (VDEW 4th edition 2001) and DIN 0838 are complied with. Product Solar Inverter Manufacturer Sunways AG, Photovoltaic Technology Macairestr. 3 - 5, D - 78467 Konstanz, Germany Sunways NT 10000 Type 15 September 2005 As from manufacturing date Applied standards Norm Title In-Plant Generation Systems to the Low-Voltage Grid Edition th 4 edition 2001 Explanations Sunways Solar Inverters of series NT 10000 are Solar Inverters that inject in three-phases and are not capable of isolated operation. The NT 10000 consists of three single-phase inverters with a three-phase voltage monitoring system that inject into different phases. These integrated inverters control their phase angle independently of each other. They are equipped with a voltagemonitoring system and a three-phase monitoring system for any reduction of the linked voltage, in accordance with section 2.4.2 of the VDEW directive (4th edition 2001). Therefore, no always accessible isolating point is required (see section 2.1.2 Schaltstelle mit Trennfunktion [Control Point with Disconnection Function]). A routine test is carried out with each device to make sure the turn-off values of the three-phase voltage reduction protection are maintained. Subject to changes.
