Fronius IG Plus V 3.0-1 UNI Solar Grid-Tie Inverter

High solar power harvest from a small package

The Fronius IG Plus V 3.0-1 UNI inverter and its companion the Plus V 3.8 are the smallest size inverters in the Fronius IG Plus family. This compact inverter is very efficient at 96.2%. It is best suited for smaller solar applications such as residential and smaller commercial solar systems.

Designed for indoor and outdoor installations.
All Fronius IG Plus V inverters have a robust, well designed aluminum housing. UV resistance and corrosion protection enable them to be used either indoors or outdoors. 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 UNI inverters are field programmable to 208, 240 or 277 volts. This eliminates the need to install different inverter models to accommodate three-phase installations.

Flexibility and scalability
The Fronius IG Plus V 3.0-1 UNI inverter is perfect for applications like home solar power systems. Different inverter types may be combined as required allowing flexibility and scalability for the future. Time proven Fronius technology gets the most out of all solar module varieties.

Fronius IG Plus V 3.0-1 UNI Review

Grounding selectable on site.
Decide on site what type of grounding is required as the Fronius IG Plus V 3.0-1 UNI is field programmable for either positive or negative module grounding.

The unique power plug system
The connection area and power stages are installed separately from each other. This separation of main components makes installation and maintenance much easier.

Very easy and extremely safe
The connection area is attached to the wall as normal. Then the power module is simply plugged in. The power plug connects both parts into one secure unit. If service is required, the inverter connector remains on the wall maintaining all settings and configurations.

This Fronius IG inverter is a powerful, user-friendly and highly reliable solar grid-tie inverter. It is equipped for different types of solar systems, especially smaller systems (e.g. on the roof of suburban homes). The combination of different types available for selection is limitless. The ingenious processor control combined with the powerful HF transformer extracts the maximum energy yield from all types of solar modules.

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 Fronius IG Plus V 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 3.0-1 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

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.
