Qnergy’s solar hybrid system leverages the PowerGen Stirling engine to supplement photovoltaic power creating the most reliable off-grid power system.
Under normal conditions, the PV array supplies power through the system’s battery bank. The PowerGen engine sits in standby, monitoring the battery health. In extended durations of poor solar availability, the PowerGen intelligent control system will start the engine and charge the batteries. In cold northern climates, the waste heat of the PowerGen system is harvested to maximize system performance to:
- Heat propane tanks to keep fuel flowing in frigid temperatures
- De-ice communication towers
- Increase battery efficiency and prevent freezing.
