The knuckle draggin Neanderthal’s tried to destroy it %21 Golf ball sized hole in the box. The corners of the box looked like accordion bellows %0D%0AIf not for the extra thick high density foam it probably would have damage. %0D%0AI’m on the schedule to get it installed%2C so can’t really give a honest opinion now. Once it’s functional I’ll be able to give an informed review
I would personally like to thank Manny from the bottom of my hart for his support in helping return the inverter I purchased. He when out of of his way to make sure I did not have to pay any shipping return for the product. I purchased the inverter and decided I needed to return it because I was not ready for the installation, Manny was very understanding and when out his way to help me return the product and not even have to pay for shipping return. I wish there were more kind and caring human beings in this world like Manny! He gives this company reputation, honor and quality customer service!

I was a DIY solar power wannabe... that is 'til I connected with Manny... The man's a prince! He not only knows his stuff; he walked me through all things electrical. To make sure I had all I needed... he gave me his cell phone # to text him anytime I got confused... nights and weekends included. The prices were very competitive... definitely go with Manny -- you won't go wrong!

I am always hesitant to buy things at places I have never shopped... I want to give a shout out to Manny who with great patience and knowledge helped me get my orders... I felt valued as a customer and I will definitely be back in the future. I highly recommend them, they make you feel like family.
