The UNO-2.0-I and UNO-2.5-I are
packed with ABB’s proven high
performing technology. The smallest
of ABB’s outdoor range, these
products are the right size for the
average rooftop installation.
The high speed and precise MPPT
algorithm enables more real-time
power tracking and improved energy
harvesting.
Efficiency of up to 96.3%
Despite the isolated operation, the
UNO-2.0-I and UNO-2.5-I feature an
efficiency of 96.3%. The wide input
voltage range makes the inverter
suitable to low power installations with
reduced string size.
In addition to its new look, this inverter
has new features including a special
built-in heat sink compartment and front
panel display system.
This rugged outdoor inverter has been
designed as a completely sealed unit to
withstand the harshest environmental
conditions.
Highlights
− Single phase output
− High frequency isolated topology
− Each inverter is set on specific grid
codes which can be selected in the
field
− Wide input range
− Flat efficiency curves ensure high
efficiency at all output levels ensuring
consistent and stable performance
across the entire input voltage and
output power range
