8.1kW Hybrid Solar Power System w/ Generac 15kW Generator

The Akhouri’s recently built a new home in Fairfax County, Virginia, about 25 miles from downtown Washington, DC.  Their goal was to be as energy-efficient as possible with the ability to be completely off-the-grid one day.  The home design includes multiple geothermal heat pumps, 2 GE GeoSpring heat pump water heaters, solar attic fans, and premium insulation.  The Akhouri’s selected P.E.G. to install the solar PV system, solar attic fans, and backup generator.

P.E.G. designed a 8,100W solar power system using (30) Silfab Solar 270W all-black solar panels and the Schneider Electric Conext XW+ hybrid inverter system.  For secure off-grid power, P.E.G. included an 860 amp-hour deep cycle battery bank using 16 Crown Commercial deep cycle batteries.  As an added layer of protection, the system designer incorporated a Generac EcoGen™ 15kW standby generator.  The EcoGen™ allows the Akhouri’s to quickly recharge their solar batteries during periods of high demand or prolonged overcast weather.  The system design provides the best of both worlds: energy savings and energy security.
