Grid-Tied Battery Backup • McLean, Virginia
SYSTEM DETAILS: grid-tied battery backup system, powered by a 12 kW roof-mount solar PV array
PROJECT NOTES: This large solar PV system features 32 kWs of inverters that feed a 200 amp panel and a 96 kW backup battery bank. The system charges the batteries first, so the batteries are available to power the home when Utility power is unavailable. Once the batteries are charged, the solar panels power the home or send excess energy to the grid.
