Great experience, highly recommend

Having never bought from direct power before I was a bit nervous that the heavy snow might cause delays. When I called to check, the person who answered was very reassuring and understood my concern. They explained how the order was coming in two parts and everything was on schedule. It arrived on time and in great shape in spite of the weather. Great service and product.

Order process flawless. Shipping was super fast.

William Tarolli

had a bunch of questions and Christian answered them. Now hopefully after using three different inverters this one will have the correct software and will solve the problem.
Thanks for the help!

J.C.

I was a bit skeptical of buying from a new company first and spoke to Christian. He answered all my questions and made sure my order shipped quickly. I would buy from them again anytime, and I recommend them.
