Hi. I am getting g two converter system with smart panel2.Also getting 4 400 w solar and a generator. Do i need a switch panel for solar generator? . House is around 3200 sf and three AC. Thanks
This is exactly the kind of setup I want to do in my next house and I wasn’t sure if all the components that would be needed. This was super helpful to see all the pieces put together. Thanks! p.s. your house looks great!
Great video and very informative. We live in Houston (for now) so we're at the point that a backup is pretty much required. I love that we can start with the Ultra, expand as needed, and take it with us if/when we move. Your setup here is where we'd eventually like to be - its a beautiful setup.
I have a Delta Pro which I was using as a UPS for all of my home entertainment equipment. When the power flickered, everything connected went off. I reached out to support to troublshoot they essentially said that was expected because of the 30ms failover time. So yeah, really not suitable if you care about not losing power. But fine if you don't care if you lose work as long as you can start over.
This is the most complete info- merciaI I've ever seen. The narrator was to the point and covered mostly all products from EcFo. Great thanks. Joe in KS.
With the 30am 12v D.C. output, this might make a good R.V. unit. For home I don't need anything so portable. Big racks of batteries and hard wired inverters suit me fine, but I think something like this is a great choice for people who want something more integrated into a buttoned up package.
I have the Ultra with 5 batteries, cost a pretty good amount. My issues is the constant error codes that require constant manual resetting. Support is comically useless with no actual solution, it’s like an AI response that ask questions I’ve already provided. Frustrating! So far I feel I made a costly mistake.
Oh no. I’ve had a few random error codes but I’m thinking those will get ironed out with firmware. You made a big investment, you should get good service. I’ve had good luck with EcoFlow’s support but maybe they are overwhelmed? What errors are you getting?
A few months ago, the solar charger died out of the blue but they replaced it quickly. Otherwise, my Ultra has been working great. I use it every day to power a bunch of circuits via my transfer switch to reduce my energy use. Just got a plug in hybrid (Prius Prime) and have been exclusively charging it from the Ultra and small rooftop array I show in the video.
I’ve heard customer service sucks and these things need constant software and firm wear updates I would never spend that much money with such crappy customer support even though I want one no way
Hi Todd. Great video. Do you have a solution for states (Illinois) that require conduit for electrical runs? Trying to figure out how to get PV for a small solar array into my house and into my DPU. TIA!
those interlock kits are not feasable in Canada.. could be nice to mention in these types of videos where you are and what works where (if you know of course).
Nice video. I also like that you paid for the product versus so many of the reviewers who were given the product. I like how you talked about the ground loop issue. Am I understanding correctly. You have another power system battery that has a separate charger that plugs into the wall socket and outputs DC that charges the battery and then the AC unit converts back to AC and you plug that into that Ultra AC input with the switch set to slow. This avoids the ground loop. Is that correct? If so it sounds like one of the older power stations that came with an external wall charger would work well as making sure the Ultra is powered up. Am I understanding this? I see people using a SMS system to convert AC to DC and plugging into the Low PV port as a backup but that requires a way of switching between solar during the day and the SMS DC output at night if needed
Hi. Yes, any power station with a DC power brick will let you plug this into the wall while the ultra is powering circuits to avoid the ground loop. Works perfectly for me to make sure I don’t run out of power with bad weather. I was given a review unit but all opinions are my own, both pros and cons.
Great video. Quick question. Around the 20:00 you said something about not recharging the unit with AC while powering the house. I thought pass-thru was a feature? So does that mean I couldn't take advantage of cheap electricity rates at night to recharge the unit while it continues powering my house? Thank you.
Pass through charging works great because that essentially just passes the grid power through the unit. I have a specific setup where I power some circuits with the inverter on the ultra with a transfer panel. In that case, the ultra is generating its own AC power so I can’t also plug it into the grid at the same time or there will be a ground fault. Probably won’t be something you run into
I think I found a technical error in your logic when connecting two DPU’s to the 50amp Hub. You said that you would get 14.4kWh of AC output (assuming 7.2+7.2) when it is limited to only 12.0kWh of AC output when using/connecting via the Hub. The reason I know? I’m planning to use the 50amp Hub in my setup and saw that in the Specs. Still, an outstanding video for sure!
For that price, you can build a battery bank with over 28,000wh and still have over $1000 left over. I’m not knocking the system, it’s a good system. But your paying is for portability and not so much power. You can get 280ah Lifepo4 Prismatic cell for $99 a cell in you buy 32 of them. You need to get a BMS, but with $1000 left over you have a choice.
Of course a DIY setup will be less expensive, that's never a debate but the simplicity, performance, and safety of a system like the Ultra is miles ahead, especially for folks who aren't electrically inclined. I you don't know what you're doing, you can hurt yourself or burn your house down.
i have a ecoflow river 2 pro, and im using that as a UPS, however, im connected with the APC back up UPS, with this, i will have like 8 hours of runtime and with the apc i will have like 30 minutes for me to save the work i have for the computer and SAFELY shut the computer down. sometimes here in massachusetts the electricity WILL go off during that time a lightning bolt struck not from here, and whilst i was working, it knocked the electricity out, however, i had computer for like a couple of seconds before it went out.. let me try to rephrase this, for the computer i have my computer hooked into my APC on the backup UPS whilst i have my APC hooked into my ecoflow river 2 pro giving me 8 or so hours for me to be on the computer, whilst the other cord from the ecoflow river 2 pro is hooked into the grid, and i have my charging speed to 100 so i can get more charge cycles cause my computer is using like 35 watts with both moniters being like at least 20 or 30 watts totalling the wattage to only 60 to like 70 watts, if im using the fan its an additional 10 to 12 watts of power, which i dont mind at all. that will allow me to run this off grid for like 4 to 5 hours if im hooked into everything. 8 hours if i only have my 1 moniter and my desktop computer only powered.
I recently ordered the new Delta Pro Ultra from EcoFlow, but I'm having a frustrating issue. They sent me the inverter but not the battery, and to make matters worse, they charged me for the full unit. When I emailed them to ask about the missing battery, they informed me that the batteries for this unit are out of stock and won't be available until mid-July. However, when I later called their customer service number, I was told the batteries would be in stock in early July. These conflicting dates are leaving me stuck with a Delta Pro Ultra and no battery indefinitely. Adding to my frustration, their website still allows people to order the kits and the batteries as if they're readily available.
A fridge uses 2kwh a day so you need a system with at least 9-10kwh of battery power to cover that scenario. If you add solar you could probably get by with half that but you'd need some sort of generator backup if the weather is bad. Hope that helps.
@todd.parker I have a small generator but am planning to buy a better one. For Florida and our hurricanes I need to prepare. My plan is to get an ultra, extra battery, smart panel and two solar panels. I'm hoping that power only goes down for a day or two. Although last big hurricane ,we had no power for 4 days.
@@Graxis1 cool. If you get the ultra you don’t need a big generator but having an inverter model will supply cleaner power to it. Just kick it on for an hour or two to top things off when solar can’t keep up
Let's talk more about the $$$...what's your ROI on this setup? I'm assuming you did most of the work and avoided the additional cost to have someone do it all for you..or did you?
I had to invest in re-working my electrical panel this fall because I was getting water flowing into my main panel and getting the breakers wet so I replaced the main connection line, panel, broke out a sub panel with interlock, and added the transfer switch. That was well beyond my DIY abilities but something I just had to do to fix up my electrical and use power stations to run circuits. Re: ROI, I think you need to look at this as an investment for home backup that usually costs $10-20k with a gas generator. The benefit of a battery-based system with solar panels is you can get some monthly savings on your electricity bill by running some loads "off grid". For example, I've been running most of the circuits in my transfer panel (fridge, lights, boiler, water heater, microwave, etc.) 24/7 off the Ultra with solar for ~2 months so far and only dip into a grid if I run out of storage. That generates about 100kwh or power a month which will save me about $40/mo so that provides a small amount of offset that over 10 years will save close to $5,000 so that covers a decent amount of the Ultra's cost. It's not a _return_ on investment but a big offset for the cost of a system. With a gas system, you can't do any of this so it just sits there costing you money each month until you need it during an emergency
@@todd.parker Also, in the rare event that you can’t get access to gas or propane.. the panels can provide sustainable/replenish-able power. The key is redundancy.. it’s best to have everything- solar, batteries, inverters, propane generators, gas generators, diesel generators, and yes Grid power. .. if one thing fails.. the others can bare the burden.
If you have an inverter in your basement then you might be able to tie into the DC power before it goes into the inverter. I have micro inverters on each panel so AC power is coming off the roof so I had to install a separate array that is DC
Not sure I understand. Yes, I have a 12 circuit transfer switch but I also have a sub panel with interlock that powers another 12 circuits. The only things I don’t back up are things like my induction stove, electric ovens, etc that are too power hungry and not essential. Maybe you didn’t watch that whole video?
@@todd.parker nope I didn't watch the whole video. I was about to buy this product when my electrician asked if I understood that it will only do 12 circuits. My house has 24... No matter if I did 3 inverters and all the batteries, I could only really send power to half my house. It is not a whole home back up. It is a beautiful little system but it is click bait to say whole home imo
@RandomlyRich I think you’re talking about the smart home panel being 12 circuits. The ultra can power your whole home if you install an Interlock on your whole panel. Just watch the video 😂
Overpriced. I can build the same thing for far less with an inverter and rack batteries. Why would I want to buy this? That price would even buy solar panels on top.
A DIY setup will always be cheaper, yep, but this is more of a consumer-friendly appliance that doesn't require any technical know-how and comes with support. If you can DIY it, go for it.
you also have to understand what the WH is too, like if this is 6.9WH is, it'll be 6,000+ dollars, so its a fair price, though DIY is the best solution too as well.
You have everything connected to the EcoFlow, but how long can you run it is the big question? You don’t have enough solar to charge the system and the EcoFlow generator don’t have enough power to keep up with your demand. You need to run a real test and be on battery backup for a few days, then you will see you don’t have enough solar or generator power to keep up with the demand of your house. Especially those ac package units. Those things will suck the power out of your system in an hour or two. I’ve been working on a hole house back up for more then two years. I have close to 1kwh of batteries and I can go up to 3 1/2 days with out any sun. But… I have more then enough solar to fully charge the system. I know for a fact that EcoFlow system don’t have enough power to run your house for 12 hours. Not enough. You will need to add my batteries to keep up with your demand. Run a test, see how long you can really run. Can you run a full day or night? Find out now and not in a emergency. Good luck
Yeah, I showed how many things the Ultra can run at once (a lot) to test it's max output but running loads continuously 24/7 is a different matter. I've actually been powering most of the circuits on my transfer panel (but no AC) in off-grid mode for the last 2 months to dial things in and save on my electric bill. I've been running my full sized fridge, gas water heater and boiler, downstairs lights, microwave, internet, and a few other things every day off this system and it's been flawless. On a decently sunny day, my panels can pull down 6-9kwh at this time of the year which is enough to fully recharge the battery easily but when I have stretches of snow or clouds, it will drop to 20% and that's where I have another power station to trickle charge the Ultra so I don't wake up to dead fridge. I show this setup near the end of the video. I've been averaging around 100kwh per month of solar input and balanced the output to be roughly the same but this will increase a lot as we head to spring. When I get a second or third battery, I'll have a lot more breathing room and can run even more.
I love your whole home backup configuration! Having both the interlock and the transfer switch is awesome!
Thanks Jason!

30ms is a bit too slow for a UPS so some things may restart. The Ultra has a mix of 0ms and 20ms AC outlets so it won’t cause those issues

Great video! That Delta Pro Ultra seems like a better value than a Powerwall or other wall-mounted battery
It's a really great option if you don't need the grid integration of the PW. It's certainly much less expensive when you consider installation costs.
What a lovely kitchen and living room🥹
Thanks so much Clara!
Cool setup 👍 ecoflow is essential in providing power . I really liked the propain generator , The perfect solution .

Hi, great video. Would go with this over the Bluetti EP900 + B500 home battery backup system?
For $50k you can buy /add a 90kwh F150 Lightning and run the house pretty much indefinitely. Solar companies wontt know what hit them
Ha, you’re right. The Lightning is a rolling set of 5-6 power walls. It’s a really good price considering
Great explaining of this project and thanks for sharing!

That's super lame. If you can, return the inverter and buy from Costco. It may be cheape, you get their warranty, and you should get it right away
All I want to do is power two full size fridges, hot water heater when needed, a light and fan. That's all I want to power for min of two days.

Yeah, I showed how many things the Ultra can run at once (a lot) to test it's max output but running loads continuously 24/7 is a different matter.
I've actually been powering most of the circuits on my transfer panel (but no AC) in off-grid mode for the last 2 months to dial things in and save on my electric bill. I've been running my full sized fridge, gas water heater and boiler, downstairs lights, microwave, internet, and a few other things every day off this system and it's been flawless.
On a decently sunny day, my panels can pull down 6-9kwh at this time of the year which is enough to fully recharge the battery easily but when I have stretches of snow or clouds, it will drop to 20% and that's where I have another power station to trickle charge the Ultra so I don't wake up to dead fridge. I show this setup near the end of the video. I've been averaging around 100kwh per month of solar input and balanced the output to be roughly the same but this will increase a lot as we head to spring. When I get a second or third battery, I'll have a lot more breathing room and can run even more.
