Using A Transfer Switch With the EcoFlow Delta Pro Ultra! 3 Month Update 

Great overview! Ecoflow hit it out of the park with this unit!

Thanks for the hands on demo, I really like the direction EcoFlow is heading and their products in general.

Klein tool to identify circuit is great but isn’t that why you have kids? Another excellent video.

Doing the same thing for over a month now and seeing significant savings/month. I have the DPU with 5 batteries into a 240 splitter. One goes to house manual transfer switch running pretty much the entire house and the other to an EV charger. 4k solar in. At California peak price It’s a significant savings. All the extra goes into my car.

What up Doe Dr J' Ecoflow is changing the game with the very impressive and game changing Delta Ultra. Thanks for all the testing and hard work!! Great vid👍🏼

awesome review, Jason!

That thing is a beast! Way better than having two main head units for 240v split phase power. Can you imagine how much room two AC500's would take up! Sheeesh.

Great work and thank you for sharing!

Great video.. thanks for making it!

Well done, appreciate the detail. Thanks!

Awesome Video Brother!!🤘

A mobile welder I met, bought the smaller version as it was more stable to use than his gas generator. The output is incredibly stable and strong. Welders and other mobile power users should give them a look.

Thanks for the update! When you were showing the EF tablet/data, specifically the inflows vs outflows numbers, is the delta the "loss" between inflow-outflow? I'm assuming the inverter/"idle" energy used by the unit itself is the difference. Thank you for your efforts on all of this! Glad you can get some benefits too back to your day to day living (e.g., less $ power cost, outage protection, etc. :-)

I’m stunned to see “refurbished Ultra units” on sale so soon

Great video. Could I just use my Span Smart Electral Panel instead of a transfer switch or critical loads panel?

Bought a Delta Pro Ultra with the Smart Home Panel 2. Had it installed by an approved Electrician. The SHP2 failed in less than 2 weeks of minimal use, one of the main relays failed. Ripped it out and put in a manual transfer switch like you have, a lot less risk of failures. The DPU has had a couple of weird battery cycles where it would say it was charged when the input power could not have charged it that fast, and the discharge cycle was similarly shortened. It did correct itself after that though.

Outstanding review! It's a bummer that this unit is not backward compatible with their Delta Pro and SHP1, unfortunately. Appears part of their model is to rip & replace vs. make these new devices backward compatible.

I'm looking at options for back up power. Been looking at generac propane, and the Ecoflow system. I really like the ecoflow but one thing you brought up was a firmware update. That concerns me in the event folks can't get future updates for whatever reason.I dont want to sink a chunck of money into a system that may not be able to function properly because I cant get an update. Other than that, I really like the ecoflow

There is a lot to like about this, but the thing that keeps me from pulling the trigger is the inherent vendor-lock design. What happens in 5 years when this is several generations behind and can no longer be expanded or even supported? A DYI solution would allow substitution of components for repair or replacement. With this, you would have to replace everything.

Hey Jason. Really appreciate the info here. I just wired up the same setup and waiting for my panels to arrive. At 4:51 you show circuit breakers for your panels. Are these necessary or are they more of a precaution? Does it depend on the size of the array? Thanks!

Hey Jason, Great review!! The Ecoflow Ultra is awesome!! I have the same setup with the 10 circuit transfer switch and the BLUETTI AC300. I’ve been running it now for close to 2 years without any issues. My electric bill has dropped from the $250s to 130s in daylight savings time. The Ecoflow has the upper hand with the 240 without needing an extra head unit and hub. I also like the compact size of the Ecoflow. The technology keeps getting better and what you buy today might be dated in 6 months to a year. I really like the Ecoflow Ultra.

This thing looks great! How long do one of these units last before major maintenance is needed or completely replaced?

I have a similar Setup like you, The DPU with 2 expansion batteries, and right next to it I have a Maxed out AC300 with 4 batteries. I wish I could find a way to use both of them, lol. But the question I have is, Have you messed around with the modes in the settings. There is a Time of Use Mode, Self Powered (the one I'm currently using) and Scheduled taks(that one confused me) The Ac300 and Ac500 was easy to setup for me for time of use my rates are higher between 3pm and 7pm. But Ecoflow seems a little more complicated. I got frustrated and gave up on the other 2 modes. On a side note I do love the Data Tracking, something I wish Bluetti should have but doesn't.

Mine has been working ok as a standalone unit apart from annoying RFI that is a problem for amateur radio (ham radio). I also don’t like the orientation of the power poles for dc output.

Good video and appreciate proof of usability. Will be more telling when you have multiple years and varying seasons. I am curious why so many are setting up a transfer switch. Why not tie the whole panel to an input and just isolate the circuits you want? This gives you total control over your entire home as needs arise by turning on or off circuits, not just locked into whatever you thought might need with a transfer switch.

Is it possible to have it plugged into a live outlet to charge off the electrical grid if you get below something like 10% or 20% charge?

Jason just a heads up that between :49 and :54 seconds your video drops signal (blacks out).

Hi. Great video. I just received my eco flow pro ultra kit with an extra battery. Im only using ac outlet to charge. The app will not allow me to charge when battery discharges to 90%. Your solar charge allows you to start chargingwhen you reach a certain point. Does the ecoflow tablet allow access to more setting??

Jason, have you calculated how long it would take to pay for itself in energy savings, at your current usage, were you to have paid full retail price?

I`m trying to decide what`s the best thing to get before hurricane time here which is almost always August. I got a 20 ft 8 gauge MC4 cable to get more amps to my 60 amp mppt charge controller because I cannot decipher the badly written manual to use anything but 12v input. I can`t risk a mistake. I only have an 8 gauge cable to my battery. I only need 500-600w charging because that`s all I have room for and my AC is 380w. Shade moves in by 4pm and begins shading panels so parallel is the only practical thing here. I had planned to be on an open lot without pine trees but that isn`t what happened so sun here is 10am to 4pm max. I have 6 gauge cables to eventually upgrade to my battery but they have to be cut properly and I have a knife and hack saw blade. I`ve been considering a power station with 500w solar input so I can power my AC with it but for that price I can get another 300ah battery...but it will need charging. So....a power station is probably the most practical way to get air conditioning during the hottest part of the day without buying a complete new system or damaging something trying to upgrade mine while trying to break the broken English code in my manual. If there was a way to quickly charge a big battery with a gas generator it would be nice but any charger over 20 amps is very expensive and risky. I wonder...can you use three 20 amp chargers at the same time? Or even two? Or will a whole lot of things get ruined real fast?

hey Jason, what is a decent size power source for a 2-bedroom condo? In case of a blackout. How size soler generator would I need? Thanks!

What was the solar charging issue you had early on? Was it the “479” error code that shows up in red numbers? I had that issue on mine, but I haven’t done any firmware updates as of late.

Does this have dark start like the Hysolis Apollo?? In other words, if it shuts down on 0% and solar comes up in the morning, can it start up at a designated percent power available?

If you run two dpu's together can you use the solar imput for both?

so why don't you have it charge from AC and not panels on cloudy days instead of manually turning off circuits? Can't you program it to automatically switch to AC when solar array input is low? Can the AC input charge from any 110v outlet? Suppose to get 3000+ charging cycles out of this unit, I wonder if you would count each day as a cycle. Very cool setup you have. Thanks

Where could I get the same mounting brackets and rails for my carport? I have the same steel panels. Could you direct me, please 🙏

Jason, obviously your ROI is not great at this point, however, it should be easy to calculate your monthly savings, so how much have you saved off of your monthly electric bill?

Sorry if this is a dumb question but I'm a total noob when it comes to transfer switches. My question is, how do you alienate certain appliances if they're on a circuit with multiple other things? Like running your lights but not your stove or dishwasher etc? Or do you have to run everything on that particular circuit?

just wondering, but the day you were not at home and didn't use the system, what was the reasoning behind not using it at all? did you switch the loads to line and turn off the ecoflow? just wondering thanks.

I can see the brand new Delta Pro 3 in the background at 8:50....

Theoretically, if you bought a 130kwh F150 Lightning and used it as a massive battery bank, could you run the DPU for days if not weeks at a time?

Im going to get the same setup as this. Anyone have any recommendations on where to get my solar panels? looking for 8 to 10 panels.

Can you set up the charge percentage example max 80% some type of battery life saver as Samsung phone

the transfer switch must be 50amp or 30amp? thanks

I have had a few issues with mine and would love to find someone that can help me find some answers, would you be willing to help?

I spy what appears to be a Delta Pro refresh...

What would this system cost…installed…estimate , ball park. Professional electrician

5:32 - how is it you're at 97% with two batteries, have 2200w coming from solar, only 500w going out, yet the estimated runtime is only 20 minutes??

I have 2 Bluetti AC300 & 24kwh worth of batteries & am running my kitchen & living room 24/7 rather than using the batteries as backup in case of an outage. I figured since I paid a lot of $ for all this hardware, I wanted it to save me money since electricity is very expensive here in California. Is that an inappropriate use for these systems? And I really drool for that Ecoflow inverter. My son is running a machining business out of my home & his machines use a lot of juice. I'm trying to convince him to buy the Ecoflow for his shop.

Didn't EcoFlow just update these systems?

fake review ..! this is nothing but a paid comercial
