Buying solar online should not mean guessing your way through the install. Here’s what you get with Off-Grid Source.
I haven’t used my Delta Pro yet, but I am excited about the versatility of this generator. I’m an avid RV’er so having a portable generator that can power my RV when I’m off the grid camping is pretty excellent to have that capability. Furthermore, this Delta Pro model can be used as a home power generator backup as well. I still need to get the home power station but the site says it’s currently sold out…bummer. If you’re someone who RV’s and also wants something that is compatible with using this product for home too. This is definitely the generator to have. Finally, this Delta Pro generator is safe to use in doors which is a huge factor in deciding to purchase this generator. I hope this helps other potential customers to purchase the Delta Pro generator with 400W solar panel.
Just love my Eco Flow system. We don't have very many outages but when we do it's a total pain since both my wife and myself work from home. I really can't afford for things to be down for long. With the Smart Home panel and one Delta Pro I have the piece of mind knowing that things will seamlessly keep right on going. I plan on a future solar expansion to help charge and run my electrical.
Bought my first Delta Pro to go along with a Delta 2, Delta 2 Max EB & Dual Fuel Generator that I previously purchased. So far so good. So impressed by it that I just recently purchased another & I'm awaiting shipment. I'll be more than ready for the next power outage.
Haven't used or tested the unit yet but love the build quality. Pretty heavy but that was to be expected with the size of the battery. With the handles up top and the extended handle and wheels its pretty easy to move for the weight.
Purchased a Delta flow and dual fuel generator the first. Wasn’t sure if I wanted to spend all the extra money on another Delta pro. After going back-and-forth on it . I Finally came to the realization that it was unrealistic just to have one. I want to be able to use the units all the time And not just have it sit in the corner and take the chance on the battery not being at peak potential from non-use. I could’ve just bought the Smart panel for $800. But with a new Delta pro unit and the Smart panel during the black Friday sales event. It was like I picked up the Smart panel for a few hundred bucks extra. So I spent the extra money and got the second unit and a smart panel to go with it. Was trying to figure out the best way to hook the units up to my panel. And came to the conclusion that it would be via the smart panel. Waited for the black Friday deal to buy the second unit and smart panel combo. Looked into the best options for more power. Seems that instead of spending money on for extra Delta pro batteries, I’m probably just going to buy another brand of battery bank x2 and charge the two Delta pros from them. Eventually want to get the battery bank connected to solar on the roof Have the solar feed the extra batteries and then the battery banks will feed the Delta pro units through the DC input. I’ve looked at all the options and instead of spending over $1500 for each 3.7 kW battery, I can spend less and get a 5.7 kw battery bank.
I already have around 6K invested in the system. Just really want the brains and features of each Delta pro to be able to run 240v in My Home. And above all the features that they offer in the app. Haven’t gotten around hooking the smart panel up yet, but I’m looking forward to it. The only thing I think they can improve on is when you mount the smart panel. It needs to be within 15 foot of your electrical box. My panel is in the garage and I don’t want to leave my units out in the garage where I pull my car into. Just not as clean of an environment for the price that I paid for these units. I wish they would make an infinity cable that you could extend to whatever length do you want. This will give you the flexibility of mounting it as far away as you need . (Taking into consideration that you have to use a lower gauge wire over a certain distance). But I think that would be a really nice feature That could be accomplished with just a cable. I’ve thought about connecting the smart panel in the house and running a cable off of two of the breakers back to the box. But that would defeat, the purpose of owning this smart panel. I live in an HOA where it’s tough to get solar panels put on your roof. Eventually I will. But it’s not one of my priorities right now. I bought some portable solar panels that I’m going to use for now purchase the 400 W EcoFlow solar panel. But I felt it was too heavy And too clumsy to move around. Send it back and got some of the permanent mount 100 W EcoFlow panels. They seem to be sturdier and delight enough to move around individually.
This generator/power station is very impressive. Powers my entire house excluding 240V appliances. During a five hour test run after receiving the unit, my family was able to watch TV, vacuum the house, use the microwave and toaster oven, turn on all lights and live normally. My three 400W portable solar panels kept it charged effortlessly. My family loves the fact that the Delta Pro
is so quiet. I will definitely be purchasing a second Delta Pro to run our 240V appliances. Highly recommended.
I am testing elco flow products for better backup ideas for travel campers
Been looking for a couple of years for a power backup system, after a long search settled on Ecoflow
I have tested it and love it! However I have not ran it in a grid down situation yet but have no doubt it will preform flawlessly.
So far so good . I still learning about Delta setting on my iPhone. Utune is a big help with most electronics. I like the 400 watt adjustable slower charge easier on batt. The solar panels haven’t been put up yet. Aerospace 32 years of Electronics . Thank you Jerry
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.
I originally purchased an Oukitel Abearl P5000 because it was significantly less expensive and provided 5120 Wh. However, after six months of use it died suddenly and I need an immediate replacement. I chose the EcoFlow Delta Pro and it has been excellent solare generator. I live off-grid so I rely exclusively on solar power. One of the advantages of the EcoFlow DELTA Pro is that the solar intake is 1600 versus 1000 watts of the Oukitel. So although it has less battery storage than my Oukitel, it recharges faster. Second, it is expandable. The Oukitel is not expandable. I can increase my system by adding additional plug-n-play batteries (2) and/or another Delta Pro. This is a game changer. I have only been running the system for less than 2 months so I cannot speak to durability or customer as of yet, but these are significant consideration when living off-grid in the high desert mountains of NE Arizona.

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!
Bruce D.
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.

I'm about to go off grid. I called Manny, he walked me through everything so I could truly understand what I needed and never tried to upsell me. He was honest and made a customer for life.
Ray B.
I would personally like to thank Manny... I purchased the inverter and decided I needed to return it... Manny was very understanding and went out of his way to help me return the product and not even have to pay for shipping return. He gives this company reputation, honor and quality customer service!
Roger V.
I have been talking with Manny the owner... He has not only helped me design a system but he's been assisting with the install and components. I am super pleased so far with the assistance.
