The coolcept inverter topology was first implemented in the singlephase StecaGrid. It achieved optimum efficiency ratings thanks to the innovative switching concept. The three-phase coolcept-x inverters
also benefit from the advantages of this switching concept. The three-phase topology is fully reactive current capable and therefore set up to meet demands that may be made in future as well.
The advantage of three-phase feeding is that the produced solar capacity is always symmetrically distributed on all three power conductors to the public power grid. This is the case across the whole output range offered by these inverters. The symmetrical feed-in is very much in the interests of the power supply companies, and is also compatible with domestic three-phase consumption.
