SINVERT PVS 600Series central inverters

Features and advantages at a glance

Transformerless, 3-phase SINVERT PVS inverters are

reliable, grid-compatible and cost-effective photovoltaic inverters which are used to convert solar energy into grid-compliant AC voltage for feeding into conventional power grids – thereby achieving peak efficiency levels of up to 98.7%.

The compact SINVERT PVS inverters are ideal for use in medium and large-scale photovoltaic power plants.

The SINVERT PVS500, SINVERT PVS585, SINVERT PVS600 and SINVERT PVS630 inverters are grouped together under the name "SINVERT PVS 600Series".

They consist of between 1 and 4 subunits and are available for outputs of between 500 and 2 520 kW in the following power levels:

–SINVERT PVS500:

500, 1 000, 1 500, 2 000 kW

–SINVERT PVS585:

585, 1 170, 1 755, 2 340 kW

–SINVERT PVS600:

600, 1 200, 1 800, 2 400 kW

–SINVERT PVS630:

630, 1 260, 1 890, 2 520 kW

The IEC-compliant devices are also available already integrated in an inverter station (with two to four subunits), including medium-voltage components. Besides SINVERT PVS and inverter stations, additional system components and accessories are available for implementing photovoltaic power plants according to IEC standards (see page 12).

The modularity of the series and the free SINVERT Select dimensioning software allow flexible planning of photovoltaic plants (see page 20).

To obtain early warning of faults and creeping change due to aging and wear, monitoring and control of a PV power plant via a central control room is absolutely essential. Only in this way can the operator initiate repairs and maintenance measures at an early stage and thus avoid costly downtimes. Central monitoring and control is therefore also an essential part of a preventive maintenance system.

Photovoltaic plants in which SINVERT PVS inverters are used can be monitored and controlled with the WinCC visualization system installed on a Windows PC. WinCC gives transparency to the status and energy flow of the entire plant, from the photovoltaic array and the inverters right up to the grid connection (see page 21).

The free SINVERT WebMonitor web application can also be used for monitoring the photovoltaic plant with SINVERT PVS inverters (see page 22).

With the MobileApp of the SINVERT WebMonitor, it is possible to call up the current and historical data of the selected photovoltaic plant remotely at any time, using a smartphone or tablet computer (see page 22).
