NEW FRONIUS IG PLUS ADVANCED INVERTERS

All Fronius IG Plus Advanced 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 bus-bars (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.
