Features

Fronius IG Plus V 11.4-3 Delta 3-Phase Inverter

Three phase, Two power stages, One powerful inverter.

The Fronius IG Plus V 11.4-3 Delta inverter is a two power stage inverter designed for 3-phase 208 V or 240 VAC power. Known for its long-term reliability, it is a good choice for commercial solar systems and large residential grid-tie projects.

Designed for indoor and outdoor installations.
The Fronius IG Plus V 11.4-3 Delta has a well designed durable aluminum weatherproof housing with UV resistance and corrosion protection. Fronius inverters are among the few tested and approved to operate at 122° F.

Integrated DC disconnect.
No external DC disconnect installation or cabling is necessary. This inverter comes complete with an approved, built-in, lockable and load breakable DC Disconnect.

The unique power plug system
The connection area and power stages are installed separately from each other.

Grounding selectable on site.
Decide on site what type of grounding is required as the Fronius IG Plus V 11.4-3 Delta is field programmable for either positive or negative module grounding for your 3-phase grid-tie solar system.

Wi-Fi Connectivity
Featuring standard Wi-Fi capability built-in to the inverter, you can take advantage of solar power performance monitoring and logging options.

Fronius IG Plus V 11.4-3 Delta Inverter Review

The Fronius IG Plus V 11.4-3 Delta 3-phase inverter builds on a successful model with multiple enhancements from the IG series including maximum power harvest, a built-in six circuit string combiner, integrated, lockable DC disconnect, significantly improved efficiency, and unbeatable reliability. Larger power stages expand the proven Fronius IG family in a single inverter. Fronius IG Plus models may be retrofitted with the Fronius Arc Fault Detector card for NEC 2011 compliance

HF transformer switchover

Fronius transformer inverters use a high-frequency (HF) transformer. The automatic transformer switchover facility produces three efficiency peaks. The result: a constant level of efficiency across the entire input voltage range, resulting in higher yields. Other advantages of HF transformer technology are the compact, lightweight design, a high level of efficiency and safety as a result of the electrical isolation.

Fronius Module Manager

Whatever solar panel array you decide on, whether monocrystalline, multicrystalline or thin-film, this inverter always fits perfectly in the system-concept. The "Module-Manager" is software integrated into each Fronius IG inverter that optimizes the earnings of your system in each and every situation. The Module-Manager does a first class job and leads to optimal results.

The IG Plus V 11.4-3 Delta inverter is compatible with all solar panels. What makes this inverter even more appealing is the intuitive operation and ease of use, together with its highly informative analyses of system values in every situation.

MIX™ Concept Technology

Commercial Solar Systems

An important advantage of having a Fronius IG Plus inverter involves the exclusive MIX™ (Master Inverter eXchange) concept. Like its predecessor, the Fronius IG, the IG Plus V Delta series has more than one power stage. An inverter becomes significantly more efficient with a DC loading of 25 or more percent of the nominal rated output.

Fronius MIX™ technology provides more yield. Two power stages are combined in a single device. Depending on the level of available power, either one or both power stages work together. Advantages include higher yield during partial load conditions and significantly reduced operating hours. Read more on our Fronius inverters page.
