Description:
Kirkland Solar Project where we first installed a new 50-mil IB Roof System. Next, we installed a grid-tied battery backup solar system using an OutBack Power GS8048A Radian inverter along with OutBack Power’s GH 200 batteries. SolarWorld 280-watt PV modules were used on the roof. In this impressive solar system, when the grid is running properly, your home or business will use power generated from your solar panels or pull electricity from the grid. Any excess power generated over and above your needs goes back to your utility company for credits on your power bill in areas where net-metering is available. In the event of grid blackouts, these systems will switch to “off-grid mode,” drawing power stored in your battery bank to power your home and using your solar panels to recharge your battery bank.

Kirkland Solar + Battery Backup Project
Pinnacle Roofing Professionals completed this Kirkland, Washington solar and battery backup project by first installing a 50-mil white IB PVC membrane roof, then mounting a grid-tied solar array with battery backup. The system features SolarWorld 280-watt PV modules on PV Quick Mount and Iron Ridge racking, managed by an OutBack Power GS8048A Radian grid/hybrid inverter and GH 200 batteries.
How the System Works
- Grid-tied savings: When utility power is available, the home uses solar production first and draws from the grid as needed. Excess solar power can flow back to the utility for net-metering credits where available.
- Battery backup: During grid outages, the system automatically switches to off-grid mode, using stored battery energy to power essential loads.
- Solar recharging: While in backup mode, the solar panels continue producing electricity to recharge the GH 200 battery bank during daylight hours.
