The three-phase coolcept³-fleX inverters also enjoy the advantages of this circuit. The three-phase topology is fully reactive-current capable and thus also prepared for future requirements.
The advantage of three-phase feed-in is that the solar power produced is always distributed symmetrically over all three grid conductors and fed into the public grid. This is the case with these inverters over the entire power range. The symmetrical feed-in is entirely in the interest of the energy supply companies and also corresponds to the three-phase consumption in the household.
The very high efficiency results in a peak efficiency of 98.6%, which means that less power loss has to be generated and dissipated to the environment. These are your yield advantages.
Since a three-phase feed-in feeds energy into the grid on at least two phases at any time, intermediate energy storage in the device - as is the case with single-phase feed-in - is not necessary. Thus the coolcept³-fleX inverters completely dispense with the electrolytic capacitors required for intermediate storage, which can influence the service life of an electronic device through possible drying out. When using coolcept³-fleX inverters, the plant operator therefore has the prospect of a long service life.
In addition, a new, unique cooling concept inside the inverters guarantees an even distribution of heat and thus a long service life of the devices.
The StecaGrid has a graphic LCD display with which energy yield values, current performance and operating parameters of the system can be visualised. The innovative menu offers the possibility of an individual selection of the different measured values. A guided, pre-programmed menu ensures smooth, final commissioning of the device.
The lightweights with only 12 kg can be easily and safely mounted on the wall. The supplied wall bracket enables simple and very convenient installation. It is also not necessary to open the device for installation. All connections and the DC circuit breaker are accessible from the outside. For the DC connection, the Sunclix mating connectors are included in the scope of delivery.
