The three-phase StecaGrid inverters are perfect suited for commercial rooftop systems right through to megawatt parks. Due to their output voltage of 460 V and their input voltage of 575 V to 900 V the StecaGrid 23000 3ph is the ideal player for medium voltage applications in large scale PV plants.

They comply with all requirements for IP 65 protection: their housing provides reliable protection from dust and water, including high pressure washing. These systems can therefore be installed out in the open without any problem.
Plug & play installation
The StecaGrid inverters are easy to handle and compact. Installation is safe and easy with simple plug connections and low weight. Installation costs are minimised because the devices also remain closed during installation.
Easy operation
Operation and monitoring are easy, further facilitated by the graphic display, the integrated RS485 interface and an Ethernet connection. The integrated data-logger collects and records all important operating data.
High efficiency
Even at low irradiation, the three-phase inverters achieve an efficiency of up to 98.3 %. As a result of these high efficiency levels convection cooling is all that is needed to dissipate the heat. This ensures, in addition to noise-free cooling, the maintenance-free inner workings of the inverter.
