IG Inverters Fronius IG Inverters Fronius IG inverters offer high efficiency, precision maximum power point tracking, and intelligent thermal management, all of which result in superior energy output from grid-tie photovoltaic systems. Their wide input voltage range (150-450 volts) permit the use of modules in any power and voltage range. Their light weight and innovative mounting hardware make them very easy to install. Fronius IG inverters come standard with an integrated LCD that displays and records over 20 parameters pertaining to inverter and system operation. Fronius inverters have 3 expansion slots that allow you to add features like external sensors and remote displays. You can use a personal computer to update the inverter with the latest software upgrades. The larger inverters (over 3 kW) are built with the same power stages as the smaller ones, but use 2 of them. When these inverters see array capacity at less than half, one stage turns off, giving the inverter higher efficiency during periods of low insolation. UL Listed. 10-year warranty. Extended warranty available. IG Plus Inverters - Coming at the end of 2008 Fronius IG Plus inverters will be available Q4 2008. They offer all the features of the IG and add a lockable code-compliant DC disconnect with fused string combiner in a separable connection compartment that stays on the wall if the inverter needs to be serviced. The single phase inverters are field settable for 208, 240 or 277 volts. Two true three-phase output units are also available. They can be configured for positive or negative ground. UL Listed. 10 year warranty. 15-year warranty available. | Model | Maximum AC power | DC array voltage | LCD display | CED efficiency | Max DC current | AC output volts | Weight (lbs) | IG 2000 Item Code 030-03402 | 2000 W | 150-450 | Yes | 93.5% | 13.6A | 240VAC | 26 | IG 2500-LV Item Code 030-03410 | 2350 W | 150-450 | Yes | 93.0% | 16.9A | 208VAC | 26 | IG 3000 Item Code 030-03403 | 2700 W | 150-450 | Yes | 94.0% | 18A | 240VAC | 26 | IG 4000 Item Code 030-03405 | 4000 W | 150-450 | Yes | 94.0% | 26.1A | 240VAC | 42 | IG 4500-LV Item Code 030-03412 | 4500 W | 150-450 | Yes | 93.5% | 29.3A | 208VAC | 42 | IG 5100 Item Code 030-03407 | 5100 W | 150-450 | Yes | 94.5% | 33.9A | 240VAC | 42 | IG Plus 3.0 Item Code 030-03481 | 3000 W | | | | | 208VAC 240V 277V | 55 | IG Plus 3.8 Item Code 030-03483 | 3800 W | | | | | 55 | IG Plus 5.0 Item Code 030-03485 | 5000 W | | | | | 84 | IG Plus 6.0 Item Code 030-03487 | 6000 W | | | | | 84 | IG Plus 7.5 Item Code 030-03489 | 7500 W | | | | | 84 | IG Plus 10.0 Item Code 030-03491 | 10,000 W | | | | | 108 | IG Plus 11.4 Item Code 030-03493 | 11,400 W | | | | | 108 | IG Plus 11.4-3 Item Code 030-03495 | 11,400 W | | | | | 208/240V | 108 | IG Plus 12.0-3 Item Code 030-03497 | 12,000 W | | | | | 277 | 108 | | Item Code 030-03471 | Extended Warranty - 15 years total | |
