Our Grid Down Redoubt Selection Tool will help you calculate the total amount of energy your home could potentially use (called the load) and then tell you which Grid Down Redoubt system is best for you.
One question we get asked a lot is: If I have solar panels, how long will it take to charge my Redoubt system? With our new calculator, you can estimate just how long it will take to charge your system using solar panels.
Our Grid Down Redoubt Battery Life Calculator is an advanced tool that will tell you how long your Redoubt battery may last based on the amount of energy you select to be used per day.

I’ve worked with alternative power systems for 20+ years. It’s very gratifying to see industry leaders EMP Shield and Grid Down combine there products to provide the highest quality back-up power.
The reputation of these two companies, backed up by their warranties, is just what this industry needs.

Many people think a generator is all they need for a disruption in electrical service. They’re wrong. You need two additional things: A way to store the excess electricity and EMP protection.
Grid Down Redoubt is the solution. And it includes EMP Shield, which is the most trusted name in EMP protection.

Finally a company does it right! An all in one home battery system that will allow you to sell power back to the grid and use it to power the home off grid if the power goes out! I also love that it has an outstanding 25 year warranty. The icing on the cake is that it is also hardened against all types of Electromagnetic Pulses. I give this system 5 stars and can’t wait to get one installed in my home!

We’ve searched for years to find the right energy storage system for our home. It must meet our daily needs AND take care of us when the grid goes down. Grid Down Redoubt is exactly what we have been looking for. We will rest easy knowing that we have the power to take care of the ones we love. The EMP protection (upstream and downstream), ease of use, safety rating, and the 25-year warranty on the entire system are what sold us on Redoubt. That gives us peace of mind!
I have the Grid Down REDOUBT installed and I love it!
Grid Down has teamed up with Lion Energy (which I have owned their Sanctuary system for 2 years now and love) To make what I think is the best Energy Storage system even better! They are making it Lightning and EMP protected and easy for the DIYer to install.
