StecaGrid - Model 8000+ -Three Phase Inverter
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 these inverters 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 live
While the voltage passes through zero on the grid-feeding phase, single-phase inverters must temporarily accommodate all energy supplied by the solar modules within the device. This is usually realised by electrolytic capacitors. These components influence the service life of an electronic device, due to the possibility of drying out.
With three-phase inverters, energy is fed into the grid on at least two phases at all times. Thus, the necessity of intermediate storage of energy in the device is greatly reduced, which is of benefit to the system operator with regard to a longer service life.
Flexible connection
Due to the wide input voltage range of 350 V to 845 V, and a maximum input current of 27 A / 32 A, all commonly available crystalline solar modules can be connected to the inverters in various configurations. Beyond this, the system is also approved for use with CdTe and CIS / CIGS thin-film modules. Four plug/socket pairs are available for flexible, mechanical DC connection.
Easy handling
The StecaGrid 8000+ 3ph and StecaGrid 10000+ 3ph have a graphical LCD display for visualising the energy yield values, current performance and operating parameters of the system. Its innovative menu allows individual selection of the various measurements.
The guided, pre-programmed menu allows easy final commissioning of the device.
Despite their high output, the inverters are wall-mounted devices. Thanks to the high degree of protection, these inverters can be installed indoors or outdoors. Due to the integrated DC circuit breaker, installation work is made easier, and the installation time is reduced. It is not necessary to open the inverter during installation.
Flexible system design
The combination of the StecaGrid 8000+ 3ph and the StecaGrid 10000+ 3ph allows optimum design for almost any power class. A diverse range of combinations are possible but they all share the same goal: the effective use of solar irradiation.
Guarantee service
The StecaGrid 8000+ 3ph and StecaGrid 10000+ 3ph come with a 5-year guarantee as standard. The guarantee period can be optionally extended up to 10 years.
