Item: Price:

Protect your family's power supply by upgrading your grid-tied solar power system. With the use of a technology called AC Coupling, our American Independence 4400 allows you to put your solar panel array to work even when grid power is not available. You'll now be able to enjoy the independence from power companies that comes with off-grid systems.

Easy and safe to install, this AC Coupling Kit is designed to work with grid-tie systems between 2,000 and 4,400 watts in size. It includes a Magnum MS4448 PAE sinewave inverter, a remote control, a battery monitor, eight maintenance-free AGM batteries, and a lockable metal cabinet.

If need more batteries, see our Add-on Package below. Be sure to check with one of our technicians to make sure that your battery bank is correctly sized to your solar panel array.

How does AC Coupling in this system work?
The Magnum Energy inverter is on "standby" until the utility company goes down. With any interruption in the grid power, the Magnum inverter comes alive to create a local grid inside your home or building. Your gridtie inverter will continue to operate with full output to allow normal operation of your critical loads. When grid power returns and stabilizes for 5 minutes, the Magnum inverter defaults back to the grid to keep your critical loads running. Meanwhile, the gridtied solar panels never know the difference. Read more about AC Coupling here

Deciding what needs to be powered when grid power is down is much like sizing an off-grid system. Read Load Evaluation Worksheet to understand how to determine which critical loads you will be able to power. If you need to expand capacity, you can always add more solar panels and batteries, and those will qualify for an additional tax credit.

See all AC Coupled Systems here, or all of your options for back up power here. Call Wholesale Solar for help evaluation which system will best suit your needs: 1 (800) 472-1142

This kit will qualify for the 30% Federal Tax Credit.
