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."
About KACO new energy:
KACO new energy, headquartered in Neckarsulm, Germany is one of the world’s largest manufacturers of inverters for grid-feed solar power. The product line-up covers the full power range, from single units designed for a family home up to complete systems for solar parks producing megawatts of electricity. Since 1999, KACO new energy has supplied inverters with a cumulative power output of 12 gigawatts. This offering has been extended to include solutions for PV self-consumption and energy storage, devices for grid management, as well as products and value-added services for utility-scale projects. KACO new energy is the first company in the photovoltaic industry to achieve CO2-neutral production and in 2014, celebrated the 100th birthday of the original parent company which, at the end of the 1930s, was one of first ever inverter manufacturers.
