 Collection air conditioners

and heat pumps manufactured after April of 2010 are

factory-equipped with components that make them

solar-ready. These units can be matched with

solar modules and other optional equipment so that they can

become part of a SunSource

®

 Home Energy System.

Units can be upgraded for use with solar equipment at the

time of installation or in the future.

Solar energy is first used to meet cooling/heating demands.

When the outdoor unit is not operating, the system powers

lighting, appliances and other electronic devices in the

home. Any surplus power is sent back to the utility company

for a possible credit (check with your local utility company for

availability).

See bulletin number 210680 for a complete list of all

available SunSource

 Pre-engineered Kits for ordering.

Wiring runs from the roof-mounted solar modules to the

outdoor unit. From there, power travels to the home

electrical service panel using the existing outdoor unit power

wiring.
