PRESS RELEASE | The Sunny Tripower CORE1 inverter from SMA Solar Technology reduces installation times for commercial PV systems by up to 60%, the company says.

The first free-standing string inverter for decentralized rooftop and ground-based PV systems is the basis for the new SMA solution aimed at optimizing commercial self-consumption of solar power.

In addition to a 50kW power output, the Sunny Tripower CORE1 delivers an extensive range of communication and grid management functions.

“Our engineers have developed an inverter that cuts costs considerably by ensuring an up to 60% faster installation time. Thanks to its fully integrated design, the string inverter also produces cost savings for logistics, labor, materials and service,” said Nick Morbach, executive vice-president of SMA’s Commercial business unit.

SMA unveiled the world’s first free-standing string inverter for commercial PV systems at the US solar trade show Solar Power International last year.

The inverter can be set up without additional mounting racks on flat roof surfaces or in ground-based PV systems, but may also be assembled in the traditional way using module racks or within covered parking spaces.

With a capacity of 50kW, the Sunny Tripower CORE1 is ideal for use in commercial PV systems up to the megawatt range.

Its six MPP trackers ensure the outputs of connected modules are always matched to generate the highest yields — even in shading.

The string inverter has 12 direct DC inputs, which can be controlled using the integrated DC switch. The parallel connection featuring two DC inputs for every MPP tracker eliminates the need to use string fuses, thus cutting labor and material costs.

Integrated WLAN allows for straightforward configuration during commissioning, SMA says.
