Getting the maximum earnings in months with less intense sunlight, on cloudy days or even in the early morning and evening hours, requires an inverter that must be able to quickly and precisely react to the smallest weather changes and also be able to operate efficiently, reliably and uninterrupted. pre-engineered To achieve this goal, the Fronius R and D department started with the proven Fronius IG series and looked for ways to apply new solutions and innovative ideas in many areas. Fronius IG Plus V inverters offer high efficiency, intelligent thermal management, light weight and easy installation. The Fronius IG Plus can be installed both inside and outdoors.

Because of its wide input voltage range of 230V to 600V, it is well-suited for use in numerous solar systems. The inverters' integrated LCD displays and records over 20 inverter and system operation parameters. All Fronius IG Plus V inverters include a lockable code-compliant DC disconnect with a built-in 6-circuit fused string. The internal string combiner can accept fuses up to 20A per circuit. Fronius inverters have 3 expansion slots to add external sensors, remote displays or other options. Inverter firmware upgrades can be made using a PC or laptop. The 5 kW and larger inverters have multiple power stages that can inactivate during periods of low insolation to maximize efficiency and energy harvest. CSA Listed to UL 1741 for the U.S. and Canada. 10-year warranty with 15 and 20 year warranty extension available.

Fronius IG Plus A 7.5-1Inverters & Accessories Grid-Tied Residential / Small Commercial

Headquartered in Pettenbach, Austria, Fronius has been a key manufacturer of photovoltaic electronics since 1992, particularly in the engineering and manufacturing of photovoltaic inverters for both grid-connected and off-grid power supplies. Fronius was founded in 1945, and began manufacturing battery-charging systems shortly thereafter. They made a name for themselves with premium welding technology, especially in the automotive industry. Eventually, technology and engineering standards used in welding applications transferred over to the solar electronics market. Production facilities have always remained close to home, nestled at the foot of the Alps, in Settled, and Weis in northwestern Austria, along with production sites in the Czech Republic and Ukraine. A new state of the art facility opened early 2011 in Pettenbach, reaffirming the company’s commitment to the European union. The international experts at Fronius are establishing an assembly plant in Mississauga, Ontario. The new plant in Canada was established as the main assembly line for the IG Plus line of inverters, creating hundreds of jobs for the pv industry in the Toronto area. Fronius has remained a trusted name in the renewable energy market, offering an extensive line of solar electronics, built to high quality control standards. With a powerful inverter company like Fronius, you can see why we recommend the IG Plus A 7.5-1.
