StecaGrid 1500x
Descripción
Highest efficiency with longer service life
The high efficiency results in a peak efficiency of 98.6 % and a european efficiency of up to 98.3 %, which results in less lost power that must be dissipated into the environment. This improves your yields.
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
The StecaGrid has 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 lightweights weigh only 8.3 kg, 9.1 kg and 9.6 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.
