- Outdoor Ductless Mini-Split
Inverter Series System Introduction:
System Selection:
The total capacity of ALL the indoor units can not
exceed 150% of the capacity of the outdoor unit.
However, we recommend sizing the indoor unit’s
total capacity to be less than or equal to 100% of
the outdoor unit’s capacity. If sized beyond 100% of
the outdoor unit’s capacity, when all the indoor units
receive a call for cooling/heating, the entire system
will still only be able to achieve the rated capacity. of
the outdoor unit The inverter compressor can run at
a higher frequency but may not provide full capacity
to all indoor units. Sizing above 100% is usually done
because one or more indoor units may not be in use
the majority of the time.
Additionally, the total capacity of all indoor units cannot
be less than 50% of the outdoor unit’s capacity.
System Application:
This system is not designed to be a sole source of
heat for a home/building. While the units can operate
in low ambient conditions, they cannot provide the full
rated capacity for heat at low outdoor temperatures. An
additional heat source may be required in areas such
as the northern USA and Canada during the winter.
This system must be run in modes that do not conflict.
For example, one indoor unit cannot be run in cool
mode and another indoor unit in heat mode. All indoor
units modes must be harmonized for the system to
properly operate. The fan mode can run in conjunction
with any other mode, while the cooling mode can be
run in conjunction with the dehumidification mode.
However all other modes must match among the
indoor units.

NOTE: The number of indoor units may vary depending on the capacity of the outdoor unit. This is an
example of a five (5) zone system.
