A Sunny Mini Central mounted with a ground-mounted system in Speyer, down the Rhine A Sunny Mini Central mounted next to photovoltaic solar modules. The company was founded by Werner Kleinkauf and former board members Günther Cramer (1952–2015), Peter Drews and Reiner Wettlaufer as a separate company from the University of Kassel, subsequently renamed in 2004 to SMA Technologie AG.
Inverters that target commercial applications are available for 208, 240, 277, 400, 480 or 600 VAC and may also produce three phase power. Peak efficiency: The peak efficiency represents the highest efficiency that the inverter can achieve. Most grid-tie inverters on the market as of July 2009 have peak efficiencies of over 94%, some as high as ...
Internal view of a solar inverter. Note the many large capacitors (blue cylinders), used to buffer the double line frequency ripple arising due to single-phase ac system.. A solar inverter or photovoltaic (PV) inverter is a type of power inverter which converts the variable direct current (DC) output of a photovoltaic solar panel into a utility frequency alternating current (AC) that can be ...
A power optimizer is a DC to DC converter technology developed to maximize the energy harvest from solar photovoltaic or wind turbine systems. They do this by individually tuning the performance of the panel or wind turbine through maximum power point tracking, and optionally tuning the output to match the performance of the string inverter (DC to AC inverter).
QMA [1] and QN [2] connectors are the quick lock version of SMA and N connectors. This design can save much handling time because it allows quick mating and demating without tools. Due to the smaller overall size, it can save the operating space and allows for high density arrangement.
A power inverter, inverter, or invertor is a power electronic device or circuitry that changes direct current (DC) to alternating current (AC). [1] The resulting AC frequency obtained depends on the particular device employed. Inverters do the opposite of rectifiers which were originally large electromechanical devices converting AC to DC.

Fronius has been researching and developing charging technology since it was founded in 1945. The 1990s saw inverter technology applied for the first time to pulsed charging devices for charging vehicle starter batteries. The ACCTIVA series is a starter-battery charging system. In the field of traction batteries, Fronius offers the SELECTIVA ...
