Single-phase or three-phase? For a long time, in the early growth phase of solar electrification, grid operators considered photovoltaics to be irrelevant or, at best, a small disturbance. The growing penetration of the grids by decentralised solar power plants, however, led to the awareness that the energy turnaround will not be stopped. As a result, the pressure to feed in three-phase for reliable load distribution increased. In Germany, this has always been compulsory from 4.6 kVA upwards. Countries such as Austria or Switzerland decided for such a limit later on, and drew it at 3.0 kVA. In addition, this performance range has meanwhile established itself as a typical “package size” for solar power systems – with a pack of ten modern high-performance modules.
Eight 3-phase inverters for small PV systems
Consequently, KACO new energy has opened up the product range of inverters with an AC output of up to ten kilowatts to lower outputs. In addition to the six larger units from five kVA upwards, customers can now also plan with the new units with three and four kVA: a handsome selection of inverters for residential PV systems and for small commercial applications.
PV system design made easy
The new blueplanet 3.0 TL3 and blueplanet 4.0 TL3 inverters come with “full performance” in terms of equipment features: Both have two MPP trackers, each of which can process the full DC power; they start from 200 volts of applied voltage; and they operate stable up to 950 volts. These features allow for optimal PV system design with these inverters and rank them among the most flexible three-phase inverters of their performance class on the market. Thanks to fast cabling of the DC and AC peripherals by means of plug connectors and quick menu selection via the graphic display, installation is easy – even outdoors, because of the compact housing with IP65 protection. And as always, data logger and web server are already integrated.
Michael Humburg, Sales Manager D.A.CH. is convinced: “With these all-rounders we will further expand our good standing in the area of private photovoltaic systems. I am particularly looking forward to new and well-known customers in our southern neighbouring countries, to whom we can now offer the full range of our three-phase inverters.”
