Grid-tie Solar Power System with Battery-backup in Beverly, WV

Sixteen SolarWorld PV modules back-feed power to the electric utility during normal operation.  During an outage the battery bank and electronics in the basement supply power to selected critical loads.  The battery bank has eight large Trojan deep-cycle batteries.  The backup system can supply 21 amps (240V) and the stored power is close to 17 kWh.  In a prolonged outage the solar will help charge the battery bank as though the home were off-grid.
