SunSource® Home Energy System

This Dave Lennox Signature® Collection heat pump is factory−equipped with components that make it SunSource® 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).

The SolarSynct package consists of the following components:

SLennox® Solar Subpanel installed in a Dave Lennox Signature® Collection air conditioner or heat pump unit.

SSolar modules (1 to 15 may be used to vary the amount of electricity generated).

SEnvoy Communications Gateway monitors solar power performance.

All components must be ordered separately. See the Lennox XP17 Engineering Handbook for SunSource® Home Energy System component 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.
