my Delta Pro really came to the rescue during a recent power outtage following a weather event. Really versatile device. The android app lets me monitor its status.
It performs much better than I expected. A single Delta Pro has powered my refrigerator/freezer plus an additional chest freezer for over 24 hours and still has 45% charge remaining.
My initial shipped unit was DOA. Tech support was quick to get me an RMA and the replacement unit is working great. As others have said the included application for managing the unit is flakey.
Be sure to update your units firmware right away. Both of the units I received came with old firmware that had known issues with basic functionality.
I am impressed with the staying power of the unit. It is able to support my rack mounted server farm plus fiber networking equipment for 8 hours.
I will definitely be purchasing at least one extra battery pack to extend my downtime coverage and I am looking into integrating my existing solar resources into this unit. I love the flexibility this product allows for and recommend it to you all.
Excellent product, can't wait till I have more money to buy more. I have the River w/extra battery, the River Pro with Extra Battery, the Delta Mini, the Delta Max, Delta Pro and the Delta Gas generator. They are all great products. My wish list is one more Delta Pro and 4 extra batteries.
Lots of good feature and has all the outputs and inputs I want. Though I do wish the "Car" input would support more than 8A (like up to 15A which is what the fuse on my car is - too slow to charge it at 8A). What really sold me on this was the tear down that EEVblog did of it. It is expensive but very solid build quality and lots of good features that make it worth the price. It is also HEAVY at just under 100lbs but the handle and wheels make it easy to move around on flat surfaces (could be better for going up/down the single step into my house).
