family

The Fronius Galvo 208-240 is a family of single-phase utility-interactive string inverters made by Fronius, covering the 1.5-1, 2.0-1, 2.5-1 and 3.1-1 models. The output connects line-to-line at 208, 220 or 240 V and 60 Hz, and the 3.1-1 delivers up to 3100 W at 220 V and 240 V. Maximum efficiency is 95.8% on the smaller models and 96.0% on the larger ones. All models are rated for ambient temperatures from -40 to +50 °C. Built-in protection includes an internal GFDI, arc fault circuit interruption, anti-islanding protection and reverse polarity protection. Power factor can be adjusted down to 0.85 inductive or capacitive, and the voltage and frequency trip limits are adjustable. The enclosure is rated NEMA 4X and the unit uses forced-air cooling. At high temperature it protects itself by shifting its operating point. CSA listed the family for Canada and the US as a utility interactive inverter in 2014, and later updates added firmware revisions and alternative components.

Listed as integrated stand-alone operation protection.

verified by: review-workflowverified on: 2026-10-24review note: support check: partial - Stand-alone operation protection is listed as integrated, which is islanding protection in effect, but the passages never say anti-islanding explicitly.

c5 drafted · lead Reverse polarity protection

c6 drafted · lead Constant power factor mode

Power factor adjustable from 0.85 inductive to 0.85 capacitive.

c7 drafted · lead Frequency trip

Adjustable frequency limits with settable tolerance time.

c8 verified · fact Voltage trip

Adjustable grid voltage limits with settable tolerance time (2.5-1 and 3.1-1 table).
