When the power goes out, your solar array stops working. You have $20,000 worth of solar panels on your roof sitting idle. The American Gridtie Independence Backup Power Packages (above) change this.
The American Gridtie Independence 3000 can be added to any gridtie system with a maximum of 3,000 watts of solar panels. See an example of a gridtie solar power system this size with ten 235 watt solar panels. This particular gridtie system example provides up to 320 kWh a month based on five hours of sunshine per day.
Likewise, the American Gridtie Independence 6000 can be added to any gridtie system with a maximum of 6,000 watt of solar panels. See an example of a gridtie solar system this size with twenty-four 245 watt solar panels. This one produces up to 790 kWh a month based on five hours of sunshine per day.
Because the American Gridtie Independence packages are grid independent, or off-grid, you must carefully plan which electrical loads are critical for use without grid power. Read about Sizing an Offgrid Solar Power System and check your power bill to see how many kWh/month you are currently using.
These backup power systems
allow your solar array to continue providing power and to keep your battery bank charged for days or weeks when there is an interruption in grid power. The interruption may be from rolling blackouts, from weather related power outages, or because you just want to disconnect your system from the grid for periods of time.
This package allows you to take control of where your electricity is coming from—the utility grid or from your own renewable energy system.
The heart of the American Gridtie Independence 6000 `Backup is this Pre-wired and tested Dual Magnum Energy Inverter Power Center.

Here’s how it works using the American Gridtie Independence 6000 as the example.
The American Gridtie Independence 6000 system comes with a fully loaded Dual Magnum Energy Inverter Power Center, pre-wired and tested by Wholesale Solar’s Four Star Solar Division. When the independence 6000 system recognizes a blackout or grid disconnect, it turns on in less than one second to power your backed up load subpanel until proper grid power is restored. Your gridtie solar array also keeps the battery bank charged.
The battery bank for the American Gridtie Independence Backup 6000 is enclosed in gray powder coated steel cabinet with locking door and two shelves.
When grid power is interrupted, the two sinewave magnum Energy battery-based inverters seamlessly create a "local grid" on the house side ofyour electric meter. They will work with your gridtied solar system to supply power to your critical load subpanel.
The WSS Magnum Dual Inverter Power Center will continue to operate with full output to keep your off-grid subpanel loads running. As soon as the grid power returns and stabilizes for five (5) minutes, the Magnum inverters default back to your grid-tie system inverter(s) allowing normal grid-tie operations to resume. Meanwhile, the grid-tied solar panels never know the difference.
The Independence 6000 battery bank includes eight (8) US AGM 390 amp hour 6 volt batteries which sit in a sturdy Midnite Solar battery enclosure with locking door. An automatic double safety disconnect system prevents the battery bank from being overcharged by your solar array when the grid is down or disconnected.
Because you are now running off an off-grid system, which is limited by your Dual Magnum Power Center’s capacity and by the amount of power your panels can store in your battery bank, you must carefully plan your off-grid load subpanel and think ahead about what appliances you will live with when you are off the grid. Our off-grid Load Evaluation worksheets are helpful. Also you should talk with one of Wholesale Solar’s off-grid specialists as you make your decisions.
This system has been installed by Do It Yourself homeowners or can be installed by any electrician. Your main decisions are budgetary and how many of your current appliances your off-grid system will power and for how long. |
