Fronius Grid Tie Inverters

Fronius Grid Tie Inverters

The new Fronius Primo is a lightweight, transformerless, single-phase inverter that allows for fast installation and easy setup. The Primo utilizes the new Fonius SnapINverter™ hinge mounting system, which allows for tool-free attachment and removal of the inverter from the wall mounting plate and integrated disconnect, making it practical for one person to install. The NEMA 4X enclosure allows installation in harsh environments. The built-in WiFi Fronius Datamanager card enables Internet monitoring via the Fronius Solar.web portal on computer or smartphone. The RS485 port can also be used when a Wi-Fi network is not available. Note: Customer must provide broadband Internet connection. Fronius Primo inverters are covered by a 10-year warranty, which can be extended to 15 or 20 years. These transformerless inverters work with an ungrounded PV array topology so the requirements of NEC 690.35 must be followed, including using PV Wire for exposed array string wiring.

• Internal Arc Fault Circuit Interrupter (AFCI) for added safety per NEC 2011
• Inverter sizes available from 3.8 kW to 8.2 kW
• WiFi, wired Ethernet, or Serial monitoring through preinstalled Datamanager Card
• Monitoring included via Fronius Solar.Web Portal
• 10-year warranty, extendable up to 20 years
• Compliant with: UL 1741-2010 and UL1699B-2013 for U.S.A. and Canada

IG Inverters

Fronius IG inverters offer high efficiency, precision maximum power point tracking, and intelligent thermal management to maximize energy output from grid-tie photovoltaic systems. Their wide input voltage range permits the use of modules in any power and voltage range. Their light weight and innovative mounting hardware make them easy to install. Fronius IG inverters come standard with an integrated LCD that displays and records over 20 parameters pertaining to inverter and system operation. Fronius inverters have 3 expansion slots that allow you to add features like external sensors and remote displays. You can use a personal computer to update the inverter with the latest software upgrades. The larger inverters (4 kW and larger) are built with multiple power stages. When these inverters see array capacity at less than half, one stage turns off, giving the inverter higher efficiency during periods of low insolation. CSA Listed to UL 1741 for the U.S. and Canada. 10-year warranty. 5-year warranty extension available.

IG Plus Inverters

Fronius IG Plus inverters offer all the features of the IG and add a lockable code-compliant DC disconnect with a six-circuit fused string combiner in a separable connection compartment that stays on the wall if the inverter needs to be serviced. The string combiner can be fused for up to 20 amps per circuit and a busbar is available for bypassing the combiner for higher current inputs. Fuses are not included. The single phase inverters are field settable for 208, 240 or 277 volts. The IG Plus 11.4-3 Delta and 12.0-3 Wye 277 at the bottom of the table below are true three-phase output units. They can be configured for positive or negative ground. CSA Listed to UL 1741 for U.S. 10-year warranty standard with 5-year extensions available.
