/ Fronius Primo 7.6-1 208-240 light
/ Fronius Primo 8.2-1 208-240
/ Fronius Primo 8.2-1 208-240 light
can be sized far below their nominal power class.
As the inverters start feeding in operation at a DC voltage (Minimum operating voltage) of already 80V, they are
able to operate with small PV generators of a few modules.
E.g.: Four piece standard crystalline PV Modules (e.g. 250W each) will be appropriate for proper operation.
