IG 4000 / 5100 / 4500-LV
The powerful, reliable and light weight PV inverter series.
Higher yield due to work-sharing is achieved by linking the two power circuits using the MIX™ concept, Fronius' optimized master-slave system. In the part-load range only one of the two power stage sets operates, while both work together at full-load. The advantages are noticeable, increase in yield with a simultaneous reduction in operating hours. The Fronius IG 4000, IG 5100 and IG 4500LV inverters deliver more power output for higher performance (commercial) installations, yet only weigh 42 lbs making them the lightest grid connected inverters resulting in installation cost savings.

IG Plus 3.0-1 uni - 3.8-1 uni
The first complete solution. Reliable. Proven. Smart.
A strong addition to the family: The next generation Fronius IG Plus inverter builds on a successful model with multiple enhancements,
including maximum power harvest, a built-in six circuit string combiner, integrated, lockable DC Disconnect, significantly improved efficiency, and unbeatable reliability. New, larger power stages expand the proven Fronius IG family from 2 to 12 kW in a single inverter.
The Fronius IG Plus 3.0-1 uni - 3.8-1 uni inverters are the smallest size inverters in the Fronius IG Plus family (available in 3.0 and 3.8 kW). Best suited for smaller solar applications, e.g., residential and smaller commercial applications.
Features:
- Grounding selectable on site
Decide on site what type of grounding is required as the Fronius IG Plus is field programmable for either positive or negative module grounding. - Designed for indoor and outdoor installations
All Fronius IG Plus 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. The Fronius IG Plus comes complete with an approved, built-in, lockable and load breakable DC Disconnect. - The new power plug system
The connection area and power stages are installed separately from each other. 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 connector remains on the wall maintaining all settings and configurations. - Field programmable AC output voltage
The Fronius IG Plus inverter line from 3.0 to 11.4 kW is field programmable to 208, 240 or 277 volts (Fronius IG Plus 12.0 kW only availabale in 277 volts), eliminating the need to install different inverter models to accommodate three-phase installations.

New, larger power stages expand the proven Fronius IG family from 2 to 12 kW in a single inverter.
Maximum Earnings Security
Get the most power out of every ray of sunlight. This is achieved through a complex interaction of different factors:
- Three efficiency peaks. Greater power harvest for every system size: The unique automatic transformer switching function of the Fronius IG Plus
enables not one, but three equal efficiency peaks. The result: Consistently high efficiency over a wide input voltage range. In comparison: The efficiency of inverters
without transformer switching declines steadily with an increasing input voltage.
- MIX™ Concept. 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.
- Module Manager™. The Module Manager™ keeps all Fronius IG Inverters at the maximum power point (MPP) with fast and exact MPP tracking,
ensuring that you get the most power out of each ray of sunlight. This is especially important for amorphous modules whose MPP can be more challenging to track.
- Market Leader. With a 96.2 % peak efficiency, the Fronius IG Plus inverter has the highest efficiency among high frequency inverters.
Highest Reliability
The Fronius development team has tested every detail of the design, ensuring that the Fronius IG Plus line of inverters will provide exceptional performance under all conditions.
- Smart Ventilation Design. Disruptive ambient factors such as biological infestations, dust, moisture, or coastal salt air stay outside the new Fronius
IG Plus Inverters away from the circuitry. How: Cool air is drawn in through a filter screen on the back of the inverter and routed through a closed channel over the
heat sink. This prevents contact between outside air and the circuit boards while cooling the inverter components ensuring the inverter operates consistently. All
circuit boards are also dipped in Conformal coating to provide an added measure of protection.
- Failsafe. You can rely on Fronius inverters. In the rare event that a power stage fails, the others will continue to operate. Once the replacement
power stage is delivered, it can be quickly and easily replaced by a service technician, without having to dismantle the entire inverter. The wiring box, including all
cabling, configurations and data (such as kWh production) remains on the wall, while your service technician removes two screws, exchanges the power stages, and within
five minutes the inverter is repaired.
- Longlasting Durability. The MIX™ concept increases the lifespan of the inverter. While several power stages divide up the operating hours, the new ventilation design keeps them cool, improving efficiency and lifespan. To ensure unsurpassed performance and long life, Fronius only uses the highest quality name brand components available.
The first universal inverter
Versatility as a basic principle: The Fronius IG Plus works well with all PV modules and is suitable for all system sizes.
- Compatible with all module configurations. The Fronius IG Plus works optimally with all module types, including amorphous modules. The Fronius IG Plus
works well with all module types because of its wide input voltage range, galvanic isolation, field programmable grounding option, and its precise MPP tracking feature.
- Grounding selectable on site. Decide on site what type of grounding is required as the Fronius IG Plus is field programmable for either positive or
negative module grounding.
- Designed for indoor and outdoor installations. All Fronius IG Plus 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 +131 °F
(+55 °C).
- Field programmable AC output voltage. The Fronius IG Plus inverter line from 3.0 to 11.4 kW is field programmable to 208, 240 or 277 volts (Fronius IG
Plus 10.0-3 & 11.4-3 are available in 208 & 240 only, the 12.0-3 only available in 277 volts), eliminating the need to install different inverter models to
accommodate three-phase installations.
- Universal product design. The functional principle is identical in the entire Fronius IG Plus inverter family. This means that if you are familiar with
any of the Fronius IG Plus inverters, you can also operate and service all other inverters.
- Integrated DC disconnect. No external DC disconnect installation or cabling is necessary. The Fronius IG Plus comes complete with an approved, built-in,
lockable and load breakable DC Disconnect.
- The new power plug system. The connection area and power stages are installed separately from each other. Very easy, and extremely safe: The connection area is attached to the wall as normal. Then the power stage is simply plugged in. The power plug connects both parts into one secure unit. If service is required, the connection area remains on the wall, maintaining all settings and configurations.
