Fronius Primo 3.6-1 Solar Inverter 4.210.067
The successor of Fronius IG Plus 35V-1 Solar Inverter

With power categories from 3.0 to 8.2 kW, rounded to the Fronius Primo the new SnapINverter generation perfectly. The single-phase, transformerless device is the ideal inverter for private households.

The Fronius Primo is not certified for the low voltage Directive (VDE-AR-N 4105) in Germany, however, according to VDE-0126-1-1. The use of the Fronius Primo in new plants in Germany is not possible

The Fronius Primo it is recommended in Germany, only as an inverter for the Repowering of PV systems. The use must always be agreed with the network operator
