FRONIUS, IG PLUS V 7.5-1 4,210,115,800, ISOLATED STRING INVERTER, 7500W, 208/240/277VAC

Fronius IG Plus V inverters offer high efficiency, intelligent thermal management, light weight and easy installation. The inverters’ integrated LCD displays and records over 20 inverter and system operation parameters.

All Fronius IG Plus V inverters include a lockable code-compliant DC disconnect with a built-in 6-circuit fused string combiner that can remain on the wall when the inverter is removed for servicing.
The internal string combiner can accept fuses up to 20 A per circuit. Fuses sold separately. 2 busbars (one of each polarity) are required to bypass the internal
combiner for higher current inputs, such as when an external combiner box is used. Fronius inverters have 3 expansion slots to add external sensors, remote displays, or other options. Inverter firmware upgrades can be made using a PC or laptop. The 5 kW and larger inverters have multiple power stages that can inactivate during periods of low insolation to maximize efficiency and energy harvest.
These inverters can also be used in 3-phase systems by using 3 inverters, each connected across two phases. Models ending in -3 can output on 3 phases from a single inverter.
Each inverter is covered by a 10-year warranty, which can be extended to 15 or 20 years.
