Fronius 3700Watt Grid Connect Inverter IG Plus 35 1 phase

  

With a maximum efficiency of 96%, the Fronius IG Plus 35 single phase inverter is one of the highest performing grid connect inverters available in Australia. 

  

Attractively constructed from robust aluminium rated to IP44, the Fronius IG Plus 35 single phase inverter is suitable for semi-outdoor (covered area) and indoor installation.

  

Apart from industry-leading efficiency, the technical advantages of the Fronius IG Plus 35 single phase inverter are many:

  

• East/west ready!
• Improved DCAC board design
• Flexibility; very good panel and configuration selection flexibility due to the use of a high frequency transformer. Other models of inverter are not equipped with a transformer, and therefore cannot accept some types of solar panels.
• Longevity; due to a new body design, the Fronius IG Plus 35 single phase inverter is able to pass cooling air through a sealed chamber, preventing corrosion of the circuit board and other delicate internal components. This means industry-leading service life expectancy even in coastal environments.
• Real life performance; the Fronius MIX concept delivers constant high efficiency even in cloudy weather and in under-loaded system configurations. 
• Installation; a simple and safe job even for one person. Because the Fronius IG Plus 35 single phase inverter is made up of multiple modules, the inverter can be assembled on the wall from the base unit up, meaning no heavy lifting. This is also a great advantage if service is required and modules need replacing."
• BONUS! Install and register this inverter between February 1st and December 31st 2013 and receive an added 5 years parts warranty (10 years in total).

  

MIX-concept

  

Many Grid connect inverters only achieve maximum efficiency at one point along the power scale (somewhere between sunrise and full array output power). The MIX concept allows the gradual start-up of the individual power modules within the inverter, allowing only the necessary capacity to be applied and operational  losses being minimised. This saves energy and ultimately leads to a greater yield than would otherwise be possible with traditional inverter technology.

  

Module manager

  

By operating at your solar array's maximum power point (MPP), daily energy harvest can be maximised. This is the job of the Fronius Module Manager: fast, exact MPP tracking across the inverter power modules to keep your inverter running in harmony with your solar array.
