Order process flawless. Shipping was super fast.

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!

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.
