StecaGrid 9000 3ph

Always symmetrical

Description

The advantage of three-phase feed-in is that the solar power produced is always distributed symmetrically on all three grid conductors to the public grid. This is the case with the StecaGrid 9000 3ph over the entire power range. When planning the system, this eliminates the need to avoid an asymmetry of more than 4.6 kW, which is sometimes time-consuming, by selecting individual inverters accordingly. Symmetrical feed-in is entirely in the interest of the energy supply companies. That makes lengthy discussions with these companies a thing of the past.

Long service life

Single-phase inverters have to temporarily store all of the energy supplied by the solar modules in the unit while the voltage passes through zero on the grid-feeding phase. This is usually done by electrolytic capacitors. These components affect the service life of an electronic device due to their possibility of drying out.

In three-phase inverters, on the other hand, energy is fed into the grid on at least two phases at all times. The need for intermediate energy storage in the unit is therefore greatly reduced, which has a positive effect for the system operator in terms of the prospect of a longer service life.

Flexible connection

Due to the wide input voltage range of 350 V to 800 V and a maximum input current of 32 A, all common crystalline solar modules can be connected to the StecaGrid 9000 3ph in various configurations. In addition, there are approvals for operation with CdTe and CIS/CIGS thin-film modules. Five plug/socket pairs are available for the flexible, mechanical DC connection.

Easy handling

Despite its high output, the StecaGrid 9000 3ph is a suitable device for wall mounting. Thanks to the high protection class, the inverter can be used both indoors and outdoors. The integrated DC switch reduces the installation effort and shortens the installation time. It is not necessary to open the StecaGrid 9000 3ph during installation.

Guarantee

The StecaGrid 9000 3ph has a 5-year guarantee. The guarantee period can optionally be extended to 10 years.
