Overview

Fronius Primo Single Phase Inverters


The Fronius Primo is a lightweight, transformerless, single-phase inverter that allows for fast installation and easy setup. The Primo utilizes the 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. Dual MPPT circuits and wide voltage windows allow for flexible design on two exposures with different module-string lengths.


Larger Primo inverters are available in 10.0 kW, 11.4 kW, 12.5 kW, and 15.0 kW configurations. These inverters feature four DC inputs with integrated fuse holders for MPPT 1 and two DC inputs for MPPT 2, eliminating the need for third-party combiner boxes.


The built-in WiFi Fronius Datamanager 2.0 card enables Internet monitoring via the Fronius Solar.web portal on computer or smartphone. The RS485 port can also be used when a WiFi network is not available All Primo Inverters are designed to work with the Fronius Rapid Shutdown box for NEC 2014 690.12

compliance. Rapid shutdown is triggered whenever AC is not present, and the DC voltage and current between the array and the inverter is quickly discharged. One box is required per DC string. Fronius Primo inverters are covered by a ten-year warranty, which can be extended to 15 or 20 years. Please contact your sale associate to add warranty extensions if desired.  


These transformerless inverters work with an ungrounded PV array topology so the requirements of NEC apply; including use of PV Wire for exposed array string wiring.

NOTE: As of 6/22/2020, Fronius Primo inverters no longer meet current UL1741 SA requirements for California and Hawaii.
Please check with your utilities approved inverter list to prior to using this if subjected to these interconnection requirements.
