A phenomenal solution brought together by tech experts. I purchased the Dela Pro, two extra batteries, the AC unit and the 400W solar panel. These will replace the solar setup in my 2020 RV. Why? Because they are smarter, mobile, can handle multiple charges sources at once, I can use a EV charge station and more. The app works incredibly well! The only thing I'm missing is the generator. It's not very large as generators go and I have two others but it does something the others do not. It turns itself on when the batteries hit a certain percentage of charge and turns off when it's done. Amazing technology. I'm replacing the panels on the RV roof with 400W EcoFlow panels in a frame, running the charge cables to the inside where I have the current batteries and MPPT controller and charge them that way. Are they expensive per kWh? Yes. Are they worth it? Absolutely.

I looked at various backups for my ranch. This was affordable and simple to install. I had an electrician install the bypass switch and I just connected the cords. All the house plugs run off the battery including the fridge. It is enough power for a part-day outage which is most common here. If I need more I can add another battery or plug my generator into the back of the battery to charge while using by running a cable through the laundry room window. After a couple house the utility will have given me an estimate on power restoration. No more running around with extension cords or being stuck wondering if the power will go on in a short time. I will just flip the switch and turn on the battery.

Quality unit right here. Use for my RV when we go camping. Very impressive turn key unit. I am a dummy and don’t want to deal with disconnect switch, transfer, switches, charge, controllers, and multiple other components. I wanted an easy powerful self contained unit and this is it.

New owner of the Delta Pro and two 400W solar panels. The system was easy to set up - plug & play - which is good because I am not knowledgeable about power (wattage/voltage) or even mechanics. The system charged up quickly via power connection. Eager to try out the solar panels as soon as we get a chance.

I live in Florida and have been through two major hurricanes. The first one was a learning experience. I lost my entire refrigerator and freezer, even though I had a portable generator. The issue is, you will probably be without power and unable to set up your portable generator during the hurricane. During that time you can loose all your perishable food. That means you will only have non-perishable food in the aftermath, that is, if you planned and stocked up on them. On the second hurricane, I had Delta Pro. I was able to use it indoors (where a portable generator cannot be placed) during the storm and run the refrigerator and even use the microwave to heat my frozen food (I can’t cook). Also, one of my Delta Pros was damaged by the carrier, and customer service was great at sending me a replacement unit.

The Delta Pros (2) cannot be used in bypass mode to allow Grid or Generator power to pass thru when the Dual Voltage Hub is being used. This prevents using the Delta Pro to feed a Sub Panel with 240VAC Split Phase as a UPS.

Loved my first from the Kickstarter enough to want a second. If I end up with the need I won't hesitate to buy another. Great product. And at my door out in the woods far from a city in like 36 hours. Was expecting a few weeks. Great surprise

I have bought 2 delta pros and 2 extra batteries. My goal is to run my house when i get enough battery power. I have my house running on what i have and it has worked perfectly.

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.

This was a surprising purchase! Is better than expected. Solid construction and works as advertised. Powers our 45 ft Rv and runs AC with no effort! Thanks for the fast service.
