Kaco Launches New 1-Phase String Inverters for Residential PV Systems

Kaco new energy, a German manufacturer of inverters for grid-feed solar power, has begun shipping its next generation of devices: a new family of single-phase transformerless string inverters for residential PV systems, the blueplanet NX1 M2.

These devices have output powers between three and five kVA. The designation M2 stands for the number of MPP trackers: in conjunction with the power rating, a sign of the flexible application possibilities of the inverters in the segment of small solar PV plants.

The company states that it has placed great emphasis on effortless system design, commissioning and operation for the new product family; “operators should be able to participate in the renewable energy supply through photovoltaics as easily as possible,” said the firm.

With 3.0, 3.7, 4.0 and 5.0 kVA, the new devices cover all required power levels while sharing some key features: With two MPP trackers, each capable of handling 3,500 watts, they are suitable for any roof geometry; from 100 volts starting voltage – and 80 volts as the lowest operating voltage – to 580 volts maximum DC voltage, they open an unusually wide design window to capture the largest possible solar harvest at any time of day and in any season.

At 11 kilograms in weight and less than 38 centimeters in maximum extension, the blueplanet NX1 M2 inverters are aimed at making light work of the entire logistics chain, from storage to transport to installation. Fittingly, the cabling is done via the familiar Sunclix connectors, any special tools are not necessary.

Configuration and commissioning are completed via the self-explanatory installation app, and installers and operators can then communicate with the inverters via WiFi. Any operating faults are identified soon this way, with the aim of maintaining the economically and ecologically valuable renewable energy production to its full extent.

Replacement is said to be only a matter of minutes thanks to the swap unit concept. In operation, the blueplanet NX1 M2 operate in whisper mode (<25 dB) with a minimum self-consumption of less than one watt.

Kaco says, with an extensive menu of presets, the new inverters are well prepared for use in all European and numerous non-European countries, especially where single-phase networks predominate. The blueplanet NX1 M2 are available immediately.

KACO new energy states that it is the first company in the photovoltaic industry to achieve CO2-neutral production.
