Our 15kW system purchase was smooth and seamless — delivered all the way to the UP of Michigan. They handled the utility permit revisions and replaced broken parts fast. I'll be back for future upgrades.

Every interaction with Ozark Mountain Offgrid is friendly and informative. They've been a vital part of setting up and operating our off-grid home.

Joe

Explained installation

I spoke with Matt several times before purchasing to make sure it was the right system for us. He explained things in simple terms and even walked our installer through the hookup.

T. Presley

Fast Shipping

Great product selection and fast shipping. I saved a bunch of money building the system myself instead of going with one of the big box solar companies.

Charles J.

DIY

DIY is the way to go. It didn't take me long to install everything and have it up and running.

Francis M.

Easy to Understand

I would purchase from them again. Matt, the owner, answered all of my questions about installation and made everything easy to understand.

David F.

Honest Deals

Straightforward, honest dealings are appreciated. Very few people today actually do what they say they will — Matt does. We'll recommend him to anyone considering solar.

Paul & Carol P.

Help with Upgrade

Matt helped me upgrade my KONG Big Battery system with high-quality batteries, accessories, and service. I got more energy storage in a smaller space than I thought possible.

Terral B.

Excellent!

Matt goes above and beyond — all the way beyond. He's an excellent communicator and made cutting the cord from the utility so simple. Top 3 best money I've ever spent.
