Ampner follows in the footsteps of the country’s electronic engineering innovation tradition and put together their capabilities for a total rethink of how a string inverter for solar power generation plants should and could be designed.

A perfect manifestation of these competencies is the design of Ampner ACE™ series of string inverters with the highest rated power in the world today, over 300 kW.

While many other manufacturers improve their existing designs incrementally, Ampner took the entire concept of a string inverter back to the drawing board. The result is what we see today – an extremely robust device with a small footprint and light weight yet achieving industry-leading efficiency and reliability. The first of the series, ACE 300 PV, delivers unchanged performance in extreme temperatures (-40°C to +60°C, -40°F to +140°F), and it withstands humidity, dust and salt spray for use in all climate conditions from coastal regions to mountains and deserts.

“Its high power density both in terms of kW per volume and kW per weight, combined with its extreme rated power, makes the ACE 300 PV cost-effective to store, handle, transport, install and operate,” says Ampner CEO, Mika Jantunen. “This translates into minimized downtime, lower Levelized Cost of Energy and higher lifetime profitability.”

The ACE 300 PV units are manufactured at Ampner’s own facilities using a state-of-the-art, easily scalable manufacturing concept. To complement innovative design with uncompromising reliability, only tried and tested, widely used components are utilized. This avoids teething problems that often emerge in heavy-duty production use of novelty technologies.

Ampner’s subsidiary, Testcom®, has designed tester systems and delivered versatile power electronics testing facilities and consultation to world leading customers for more than 15 years. The same rigorous standards are applied to every ACE inverter before it leaves the factory. Because they operate under the same roof, Ampner’s R&D, power system application, manufacturing, assembly and testing functions have complete synergy.

Ampner will introduce the Ampner ACE™ series and the ACE 300 PV at the Solar Power International 2019 exhibition in Salt Lake City, Utah, USA, in September.
