Inwerter Topology
The new „Coolcept“ inverter topology, with an innovative circuit design that achieves highest efficiency, has now been integrated into the StecaGrid 3000 and StecaGrid 3600.
The "Coolcept" inverter topology is based on a single-stage transformerless switching concept that uses proven standard components to implement symmetric step-down converters with downstream pole-reversing circuits.
Highest efficiency with longer service life
The high efficiency results in a peak efficiency of 98.6 % and a European efficiency of 98.2 % resp. 98.1 %, which results in less lost power that must be dissipated into the environment. This improves your yields.
The efficiencies of the StecaGrid 3000 and StecaGrid 3600 are only very slightly dependent on the module input voltage. This allows the number and type of modules to be freely selected without resulting in a yield loss.
In addition to this, a new and unique cooling concept inside the inverter ensures an even distribution of the dissipated heat and a long service life for the device.
Product design and visualisation
For the first time, the very high efficiency allows the use of a design housing made of plastic. This offers many advantages, for example in the installation. The overall surface temperature of the StecaGrid 3000 and 3600 remains very low. The inverters have protection class II.
The StecaGrid 3000 and StecaGrid 3600 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.
Installation
The lightweight StecaGrid 3000 and 3600 weigh only 9 kg and can be easily and safely mounted on a wall. The supplied wall bracket and practical recessed grips for right and left handed installers make mounting of the device simple and convenient. The device does not need to be opened for installation. All connections and the DC circuit breaker are externally accessible.
