Description 3 The inverter of the SINVERT PVS device line is used in medium and large PV plants and converts the DC current of the PV generators into AC current. This AC current is then fed into the connected power grid. The SINVERT PVS inverter design is optimized for the lowest possible losses and thus the greatest possible efficiency. Figure 3-1 Installation overview The integrated DC and AC distribution makes the system compact and cheap to integrate.
Description 3.1 Features 3.
Description 3.2 Design 3.2 Design Inverter subunit and inverter unit An inverter subunit always consists of a DC cabinet and an AC cabinet. A complete inverter unit can comprise up to 4 inverter subunits (DC/AC cabinets) that are also referred to as master-slave combinations (see Chapter Master-slave combinations (Page 22)).
Description 3.2 Design The figure below shows the higher-level function units of the inverter subunit with open doors.
Description 3.3 Operating principle 3.3 Operating principle The SINVERT PVS inverter works on the following functional principles: ● The inverters are based on SINAMICS (power unit with IGBT three-phase bridge) and SIMOTION (controller). ● 3 inputs for connecting the PV array are provided at the PV array end. Note The PV array must be connected for this purpose in 3 sub-arrays with the same total current and voltage values. ● The 3 inputs on the DC side are equipped with LV HRC fuses and DC contactors.
Description 3.4 Master-slave combinations 3.4 Master-slave combinations A SINVERT PVS inverter subunit is available in two versions: ● Master ● Slave The combination of a master unit and one or more slave unit(s) results in a master/slave combination. Master The master comprises a DC cabinet and an AC cabinet with touch panel. A master with a touch panel is required in every configuration. The master or the entire installation can be operated and monitored via the touch panel.
Description 3.
Description 3.4 Master-slave combinations Slave The slave comprises a DC cabinet and an AC cabinet without touch panel. Since the slave does not have its own touch panel, it can only be operated and monitored using an associated master or its touch panel.
Description 3.
Description 3.4 Master-slave combinations Master/slave combinations The inverters of the SINVERT PVS500, PVS585, PVS600 or PVS630 series can be used as single devices or in combination with other inverter subunits in a master/slave combination. Such a combination always has a master and can additionally contain up to three slaves. The following master/slave combinations are available.

Description 3.5 Inverter options 3.5 Inverter options The following functional expansions and options are available for the PVS 600Series: Option Option identifier on the nameplate PV array grounding - positive-pole grounding PV field grounding positive pole PV array grounding - negative-pole grounding PV field grounding negative pole Increase in max. DC voltage to 1 000 V Max.
Description 3.5 Inverter options 3.5.1 PV array grounding With the optional feature "Positive / Negative PV array Grounding", the SINVERT inverters offer an ideal choice for manufacturers who require a module ground.
Description 3.5 Inverter options Negative-pole grounding Grounding an active conductor (negative pole) means that the inverter's insulation measuring function no longer works in the normal way. A hazardous current can start to flow as soon as the first insulation damage occurs. For this reason, the condition of the system is monitored through measurement of the current between the negative pole and ground.
Description 3.5 Inverter options Switching on the PV inverter with "1000 V option" Switching on the PVS allows a variable voltage divider, consisting of series and parallel resistors, to activate the inverter DC link (without closing the DC input contactors). Thus only the required fraction of the PV field no-load voltage is present at the DC link, and not the entire PV field no-load voltage. The upstream measurement of the PV field voltage (Upv) is carried out in each individual inverter subunit.
Description 3.6 System components 3.6 System components The system components and accessories are used for optimal, flexible, and customized implementation of photovoltaic plants covering all aspects of the SINVERT PVS inverters, as well as expanding the functionality of the overall system.
Description 3.6 System components Monitoring and parameterization software ● SINVERT ConfigTool SINVERT ConfigTool is a free software program designed for configuring, parameterizing, and diagnosing inverters for photovoltaic installations. ● WinCC With our WinCC SCADA system, we offer you user-friendly monitoring and control of your entire photovoltaic plant.

Grid management 4.1 Grid management in the case of SINVERT PVS Technical requirements of the inverter The grid requirements are divided into static grid support, decoupling protection, and dynamic grid support. To meet the requirements of grid operators, you also require a plant controller such as a SINVERT PVS ControlBox, in addition to the functions in the SINVERT PVS inverter.
Grid management 4.1 Grid management in the case of SINVERT PVS Interface to the grid operator Communication with the grid operator is achieved via a SINVERT PVS ControlBox.

The setting is made as a percentage of the maximum rated power. This function is also used by the SINVERT PVS ControlBox to implement the grid operator's specifications. Note SINVERT PVS ControlBox When using the SINVERT PVS ControlBox, this value is overwritten cyclically.

Grid management 4.3 Dynamic grid support 4.3 Dynamic grid support 4.3.1 Behavior in the case of voltage dips (low voltage ride through) Due to the growing spread of renewable energy forms, you must ensure that the inverter does not shut down immediately when brief voltage dips occur. The SINVERT PVS inverter has the ability to withstand brief voltage dips and remain on the grid.
Grid management 4.3 Dynamic grid support Settings Note the following points when parameterizing the LVRT curve: ● The parameterized LVRT curve must correspond to the undervoltage protection settings. For this reason, parameterize two of the interpolation points identically to the entered limit values of the undervoltage monitor. See Chapter Voltage monitoring (Page 76). ● When parameterizing, all fields must be filled, but it is not absolutely necessary to use all available interpolation points.

Grid management 4.4 Decoupling protection 4.4 Decoupling protection 4.4.1 Grid monitoring Function The SINVERT PVS inverter monitors the public energy grid for violations of adjustable grid frequency and grid voltage limits. If the limits are violated for an adjustable time, the inverter disconnects from the grid. 4.4.2 Frequency monitoring Function The SINVERT PVS inverter monitors the grid frequency during operation.
Grid management 4.4 Decoupling protection Settings On the "Frequency monitoring" pages, you set the upper and lower limit values (in %) for the grid frequency, as well as the associated delay (in ms). The delay is the minimum time for which a fault must be active to effect shutdown. If the set limit values are undershot or exceeded for the set time, the inverter switches off with an appropriate fault message. Shutdown of the inverter takes approx. 80 ms.

Application planning 5 The following chapter contains detailed information about packaging, dispatch, delivery, storage, transport, installation location and configuring. Always read and follow the instructions given in this documentation. Observe the relevant safety notices at all times. Make sure that the conditions specified for storage, transport and installation location are fulfilled. 5.
Application planning 5.1 Packaging, dispatch and delivery Design The basic design of the transport pallet is shown in the figure below. This is a customized version of the pallet. ● This is made necessary on the one hand by the dimensions of the cabinet sections ● and on the other hand, this design offers sufficient mechanical stability for safe lifting by a crane.
Application planning 5.1 Packaging, dispatch and delivery 5.1.2 Center of gravity marking and transport position Center of gravity marking The weight mass of the cabinet sections is distributed eccentrically and asymmetrically on both the front and side faces. The weight distribution is indicated directly on each cabinet section of the inverter by the center of gravity marking in accordance with ISO 780/Symbol 7.
Application planning 5.2 Transport 5.1.5 Scope of supply The scope of supply of the SINVERT PVS inverter includes the following: ● Inverter AC cabinet mounted on transport pallet ● Inverter DC cabinet mounted on transport pallet ● Accessories pack (on Euro pallet): – 1 x cable 4 m fitted with lugs at both ends, on pallet – 1 x mounting kit for screwing the cabinet sections in black crate – Hexagonal screw M12x50, strain washer, hexagonal nut ● Operating instructions (compact) as hard copy 5.
Application planning 5.2 Transport Mechanical connection between pallet and inverter cabinet section ● Never transport the pallet with the inverter cabinet section without a secure mechanical connection between the pallet and inverter. See the figure below. ● The mechanical connection comprises strapping and bolting of cabinet base to the pallet. ● Before the package is moved, the bolting and strapping must be checked to ensure they are secure.
Application planning 5.2 Transport Danger of tipping of the transportation unit WARNING Danger to life from tipping! A cabinet, whether with or without pallet, must never be tipped in any direction. The cabinet is very heavy. Tipping it too far and causing it to topple over can therefore result in serious injury, death and substantial property damage.
Application planning 5.2 Transport Mechanical connection between the inverters The SINVERT inverter is transported in two consignment units or cabinet sections. No provision is made for transporting connected cabinet sections. Figure 5-5 Impermissible transport of two cabinet sections The inverter cabinet sections must never be transported once they have been assembled into a single unit.
Application planning 5.2 Transport 5.2.2 Transporting using pallet truck and fork-lift truck The operator of the pallet truck must always ensure that the equipment required to move the load is in good working order and that high standards of operational safety are fulfilled. Loads must always be transported in compliance with all relevant health and safety regulations as well as the instructions in this documentation.
Application planning 5.2 Transport 5.2.3 Transporting by crane 5.2.3.1 General notices The crane driver must always ensure that the crane and the equipment required to move the load are in good working order and that high standards of operational safety are fulfilled. Loads must always be transported in compliance with all relevant health and safety regulations as well as the instructions in this documentation.
Application planning 5.2 Transport 5.2.3.2 Permissible transport methods There are basically two permissible methods of transporting the cabinets by crane: ● Transport with H beam ● Transport with frame structure The cabinets are not designed to be transported by any other method and other methods are not therefore permitted. If you choose a method of crane transport which is not expressly approved in this document, Siemens will not accept liability for the consequential damage.
Application planning 5.2 Transport Procedure Whether a load is transported by crane on an H beam or a specially designed frame structure, it is always essential that the inverter is mechanically coupled to the pallet. 1. The crane ropes are placed under the load at a marked position in parallel to the side wall. 2. They are then brought up in parallel to and at an appropriate distance from the straps, from where they are threaded through a frame structure or attached to the H beam.
Application planning 5.2 Transport 5.2.3.
Application planning 5.2 Transport 5.2.4 Transport and alignment of cabinets in electrical operating areas Removing the transport locks The cabinets are attached to the pallet by means of transport locks (upward-facing screws). 1. To lift the cabinets off the pallet, you first need to undo the screw nuts. 2. To slide the cabinets off the pallet, you need to push the screws out downwards far enough (e.g. using a hammer and a thick nail), so that the surface of the pallet becomes smooth.
Application planning 5.2 Transport Procedure 1. Adjust the pallet so that it is level with the adjacent surface, e.g. floor of the equipment room. 2.
