fronius STRING INVERTERS FROM FRONIUS USA BEAT MICRO INVERTERS IN SERVICING, USE OF SPACE

Fronius IG, Fronius IG Plus V and Fronius IG Plus Advanced string inverters connect an array of multiple solar panels and can be mounted either indoors or outdoors.

Portage, Ind. (July 9, 2013) – Fronius string photovoltaic inverters available from Fronius USA are more effective than micro inverters for installers and integrators focused on optimizing both long-term servicing and use of space for customer PV systems. Fronius IG, Fronius IG Plus V and Fronius IG Plus Advanced string inverters connect an array of multiple solar panels and can be mounted either indoors or outdoors, thanks to a design feature where PV system wiring exits the bottom or rear of the inverter.


A micro inverter is always roof-mounted directly under the corresponding solar panel it serves. For inverter servicing, a panel must first be located and then disassembled by two technicians for safety reasons, according to U.S. Occupational Health & Safety Administration (OSHA) rules. Conversely, Fronius IG, Fronius IG Plus V and Fronius IG Plus Advanced string inverters can be easily serviced where they are mounted, indoors or outdoors, by a single technician with one truck roll.

"Fronius string inverters are designed specifically for ease of installation, space savings and long-term servicing, which lowers costs for the system owner. Panel disassembly isn't necessary for inverter servicing, unlike micro inverters, which saves time and maximizes PV system energy yield." said Thomas Enzendorfer, Director of Marketing and Sales, Fronius USA.

Fronius IG Plus V string inverters are available in single-, two- and three-stage designs, from 3 kW to 12kW, making them perfect for both residential and commercial installations. Fronius IG Plus Advanced string inverters help installers meet the series arc fault protection requirements of the 2011 edition of the National Electrical Code®, and are available in single- and three-phase designs from 3 kW to 12kW. Fronius IG string inverters are available in six designs from 1.5 kW to 5.5 kW and are flexible enough to handle residential or high-performance installations.
