Fronius Inverters

Fronius inverters
Fronius IG Solar

Fronius inverters including the IG Plus V, IG Plus Advanced and Galvo

We carry a full line of Fronius inverters. The Fronius IG is a basic building block inverter. Time tested and proven the IG is the model on which other Fronius inverters were built upon. The IG Plus V and IG Plus Advanced inverters include the unique Power Plug system with an integrated DC disconnect. This makes installation easier by mounting the connection module first and then "plugging in" the power stage on top. The CL inverters are designed for larger commercial solar systems. These may include large corporate buildings, solar farms and microgrids. The Fronius Galvo is intended for small residential solar systems.

All Fronius inverters are housed in a weatherproof enclosure designed to protect all internal components from the elements for the life of the solar system. They are one of the few inverters tested and rated to perform in temperatures as high as 122°F. From the Fronius IG and CL series for larger residential and commercial solar systems to the Fronius Galvo for small home systems, we have the Fronius solar solution to meet your needs.

Fronius uses a small transformer with high output and efficiency for its inverters

inverter transformer

The power stage is based on the use of high frequency (HF) technology. The HF transformer is extremely compact, yet capable of transforming considerable power. The innovative phase shift process used in the Fronius IG series also minimizes switching losses thereby ensuring a high degree of both efficiency and flexibility in terms of the unit's capacity. The unique Phase-Shift process minimizes switching losses and is able to generate ultra-high conversion efficiencies of 94.4%.

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

Output vs. voltage, the Fronius Module-Manager
Whatever solar panel array you decide on, whether monocrystalline, multicrystalline or thin-film, the Fronius IG 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 higher current produced by many high-output solar cells are no problem for a Fronius inverter. This is because of the wide input voltage range of Fronius inverters. Because of this wide input voltage range you can choose from virtually any solar panel array on the market. This feature also ensures the optimal use of the roof space without limiting architectural options.

Fronius Mix Technology™

The clever combination of multiple power stages means Fronius inverters always achieve maximum yield, even with partial-loads. This is due to the unique Fronius Master Inverter X-Change system (MIX), a development of the classic master/slave principle. How it works: All power stages are equal. The “master” is allocated alternately, depending on the operating hours. The result is that loads are applied evenly to individual power stages decreasing operating time on any one power stage.

Maximum efficiency under partial load
With MIX technology, get the maximum power harvest out of partial load ranges, e.g. on cloudy days, through a clever combination of multiple power stages in each inverter. The power stages in Fronius inverters divide up the work depending on operating hours and only operate as many power stages as required to efficiently process available power from the PV array.

Unrivaled stability
The redundant design means that even if one power stage fails the inverter continues to operate, ensuring yields are achieved. In the unlikely event a power stage fails the others will continue to operate.

Longer service life
Depending on the operation hours of each power stage, our inverters decide which power stages run under partial load conditions. This ensures that the work load is distributed equally between the power stages. The result is reduced operating time of individual power stages which increases the lifespan of the inverter.

compact Fronius IG
Many Fronius inverters are compact and small enough to be installed by one person.

An important advantage of having a Fronius IG inverter involves the exclusive MIX™ (Master Inverter eXchange) concept. All Fronius IG inverters can have 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. As solar irradiation wavers and dips in the procession of the day, the Fronius inverter can scale back and run a single power stage. The three stage 12kW inverter can now perform as a 4kW or 8kW inverter. Hence, we keep the loading on the power stages higher than would otherwise be possible with a single-stage inverter. The central processor evaluates and determines which power stage has the least amount of operation hours, then selects that power stage as the Master. This is the first power stage to be turned on and will run until the end of the day. The other power stages are the slaves that will turn on and off as needed. This keeps an equal balance on component wear and extends the overall life of the inverter.

This MIX™ concept is the ideal situation for keeping the efficiency high in low light conditions such as cloudy days or those that occur naturally every morning and evening. The IG Plus V and IG Plus Advanced boast an upgraded design and improved efficiency. This new design provides these inverters with a wider input voltage range of 230V-600V. The Vmpp is 230V- 500V and the start up voltage is 245V. When designing your systems, keep this question in mind: 15 years from now, on a hot day, will you still achieve at least 230Vmpp from the aging modules to produce the needed voltage to stay within the Maximum Power Point range?

You can trust Fronius solar know-how
Harnessing over 60 years of experience, Fronius inverters are built to be reliable, rugged and last the life of your solar system. They can withstand the test of time in harsh environments and heavy use. Fronius inverters are are built in an ISO 9001 facility and Fronius solar know-how is built into every inverter. They are built to last by a company that has been around long enough to know.
