If the cable connecting to the Delta Pro had been longer I would have given this EB a five star. But I had planned on putting the EB on the shelf below the DP and that was almost impossible. The only way I could do it was to effectively put the DP on top of the EB with a wire shelf squeezed in between them.

We have been using 2 Delta Pro and had an extra battery for each. As we Solar powered those, we realized we needed an additional battery. We are thrilled with performance and ease of use. We use them continuously and have reduced our power bill to 1/3 of what it was a year ago.

Have 2 Delta Pro's and 3 Extra batteries. You can't beat their price, warranty and customer service, for a self contained unit that's safe to use!
