Fronius IG Plus V 11.4-1 UNI Inverter

The "UNI"versal choice for compatibility.

The Fronius IG Plus V 11.4-1 UNI inverter is a two power stage inverter that is field programmable to 208, 240 or 277 volts. Known for its long-term reliability, it is a good choice for smaller commercial solar systems and residential grid-tie PV power.

IG Plus V 11.4-1 solar mounting Designed for indoor and outdoor installations.
The Fronius IG Plus V 11.4-1 has a well designed durable aluminum weatherproof housing with UV resistance and corrosion protection. Fronius is proud to be one of the only inverters 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.

Field programmable AC output voltage.
The Fronius IG Plus V inverters are field programmable to 208, 240 or 277 volts. This eliminates the need to install different inverter models to accommodate three-phase installations.

Universal Compatibility
The Fronius Plus UNI series may be used with any make or model of solar modules. Different inverter types may be combined as required allowing flexibility and scalability for the future. This makes the Fronius IG Plus V 11.4-1 UNI inverter ideal for commercial solar systems.

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 11.4-1 UNI 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

An important advantage of having a Fronius IG Plus inverter involves the exclusive MIX™ (Master Inverter eXchange) concept. Like its predecessor from the Fronius IG series, the IG Plus V 11.4-1 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.
