Lightweight
The FRONIUS IG weighs 26 lbs. How can the FRONIUS IG be so much
lighter weight than competing inverters?
 |
High Frequency
The FRONIUS IG uses a high
frequency transformer, which is substantially smaller than the 60 Hz
transformers used in inverters with one-stage topologies. The
transformer also provides galvanic isolation. Since transformers are
largely made of copper and iron, that's a lot of raw metal that is
no longer necessary. |
|
|
Active Cooling
The use of active
cooling means the heat sinks can be much smaller as well. Because
the heat sinks are just large pieces of metal meant to conduct heat
away from the inside of the inverter, smaller heat sinks means less
metal and less weight. |
|
|
Inductor Optimization
We have optimized the
output inductor to put two inductors on one coil. Many other inverters
use 2 separate inductors, which adds up to a heavier inverter. |
|
|
Lightweight Housing
The FRONIUS IG’s housing is made of lightweight aluminum,
which is significantly lighter than stainless steel while continuing to
offer the necessary durability and corrosion resistance. |
Because we use less raw materials in building each
FRONIUS IG, this
means less CO2 emissions and less material to recycle down the road. Its
light weight also means it costs two-to-three times less to ship an
FRONIUS IG
inverter. This means less fossil fuels consumed to get the FRONIUS IG
from our production factory to your photovoltaic installation. And when
it arrives, you’ll be able to pick it up. At 26 lbs, it’s a one-person
job. The delivery person, warehouse handler, and installer will all
appreciate your choice.
