You have a new product innovation, describe what that is.
The Fronius FE Inverter Line is our proven string inverter technology paired with module-level optimization, creating one seamless application. Installers and system owners can look forward to reduced installation costs, greater design flexibility and overall system efficiency, as we take integration of power electronics, module management and data monitoring to the next level. Also, as with every Fronius product, customers are provided with a streamlined support and service structure. This product innovation provides benefits of module-level monitoring while avoiding all the complication, costs and disadvantages of existing module-level products.
How is this innovation different from current technology?
The Fronius FE Inverter Line combines the advantages of module-level power electronics and string inverter topology without the disadvantages of microinverter applications. Current technology can generally be divided into three categories: string inverters, microinverters and optimizers. String inverters exhibit great strength and reliability however lack in significant advantages in design flexibility. Microinverters, although offer the benefit of module-level data monitoring, fail frequently and are roof-mounted which cause a slew of other problems in the realm of power electronics. Optimizers, such as those from SolarEdge, are also a great option but exhibit the same challenges of having many units and external power electronics to complete a functional system. This Fronius innovation transcends these products with all power electronics necessary, while boasting all the advantages of the optimizers or microinverters without a roof mount, integrated inside of the inverter.
What do you think this will mean for the PV Industry as a whole?
In complex rooftop Design layout situations, the Fronius FE Inverter Line will, for the very first time, enable installers to utilize Fronius’ industry leading truly field serviceable inverter. Without the additional BOS system costs and without the extra box (cost and installation). Simply put, you have all of the advantages without the disadvantages of the string inverter.
When will it be available or what is the timeline for roll out?
Available from select distributors starting September 2014
Where do you see Fronius USA 5 – 10 years down the road?
As the leading and premiere inverter manufacturer, we see Fronius continue to innovate and become the number one solar technology solution provider in North America.
What are the next steps for Fronius regarding this product?
