The SunSource HVAC system developed by Lennox can effectively double the rooftop unit’s efficiency rating, integrating a rooftop unit, solar modules, and microinverters to power commercial buildings. The system feeds solar energy directly into a 3- or 6-ton Energence rooftop unit, and supplies any excess electricity to the rest of the building or to the power grid. Real-time energy production is recorded and monitored by a communications module. Installation does not require a high-dc-voltage line, and each microinverter’s output is limited to 50 V. During a power outage, the microinverters stop transmitting to the rooftop unit and the main building panel.
