[@joshmalik5582]

100% agree that there needs to be an ability to turn the inverter back on automatically. I learned this by starting as a novice to solar by getting the AC200P for my unattended out-of-state off-grid camping setup. I loved it right until the first time there were a few rainy days in a row while I was gone, and the inverter shut off. That meant no remote monitoring or power for anything else there until I could return.

[@jackars8287]

Josh, like I replied to Will, the AC auto turn on feature was added to the firmware in the last couple of months. It’s under “Lab Features” in the app when you go into the Delta Pro. You need to scroll all of the way down 😃

He uses them as emergency backup at his in-town property most of the time. But when the family heads to the cabin, they throw (well, team lift) the Delta Pros into the SUV and take them with. When vacation is over, the Ecoflows com back to town.

I just tested. So I ran my ac200max down to zero but the Bluetti stayed on because it was connected to the charger. That is when the AC powered on at 5% I think. I just now ran it down to zero without any supplemental power, the solar generator powered off, and when I turned it back on, it failed to turn on the AC output even at 7%. I had to turn the AC inverter on manually. Bummer.

[@kochrd9037]

I contacted Ecoflow support about running my well pump. It normally runs at 240V and 7 amps. Startup surge is 240V, 22 amps or 5280 watts for about 1 second. They advised me that the 7200 watt surge rating of the Ecoflow Delta Pro is for a maximum duration of 0.36 seconds. So a soft start control may be required for some applications to avoid overloading the Ecoflow.

[@jackars8287]

240V would need 2 DPs. So the surge rating would be double that of 1 DP, so 14400W. 7200W @ 240V is the normal (non-surge) max output for 2 DPs.

Hey Will none of my business. Make sure you are covered on insurance for all your stuff. Insurance is tricky when you have so much stuff. Great video thank you.

[@4philipp]

A good review. Always keep in mind, the EcoFlow system is for mobile applications and temporary house backup. As such it’s capacity limitations and high price can be justified. For a stationary system, the EG4 and server rack batteries will beat the EcoFlow any day, except for setup speed (which is [largely] irrelevant in a permanent system but important in a mobile system). The expansion batteries in particular are overpriced given that they are non functional as a stand alone battery. Using server rack batteries with their own mppt for charging us a great way to expand the EcoFlow capacity. Question: can you take the EcoFlow appart and wire a (or multiple) “other” batteries to it? This would be particularly useful for all the solar generators that don’t use LiFePoS. I have the Delta (1300) and only getting 500 charge cycles to 80% is a hard sell at those prices. Comparing the Delta to Max to Pro, the price increase is in lockstep with battery capacity. However the 5-7 times better cycle life of the Pro makes it reasonably priced or the other units really expensive. So when my 500 cycles are up, I really want to connect a new better battery to it.

[@tannerh3002]

I want to bring up a problem I found with the new Delta 2. Here is the info I sent to EcoFlow. I want to bring up a problem I have found with the new EcoFlow Delta 2 that might be something many different people will run into. I, like many other people, have bought one of the most common renogy solar panels online. I will post a copy of the specs below of these panels. I am a previous owner of the original Delta and have recently upgraded to the Delta 2. The problem comes with the configuration of solar input amps and volts into the new Delta 2. I previously charged the original delta using three of these 100w renogy solar panels. To meet the original specifications of the ef delta (solar input 400w 65v 10A), I would wire my three solar panels in series to create 61.2v and 4.91A coming into the delta. As you are probably fully aware, it is safer and more efficient to run lower amps and higher volts across a wire. With the new setup on the ef delta 2 (solar input 500w 60v 15A), running these same solar panels in series creating the 61.2v and 4.91A is overloading the voltage for the new system. With the change in the configuration of the delta 2, re-wiring the panels in parallel makes them fall within the specifications. These three panels in parallel now create 20.4v at 14.73A. This setup is highly inefficient and creates a greater safety risk by running such high amps through wire. This new configuration has cut my solar efficiency down by nearly 75w and has increased the risk of fire by running the wires at nearly their rated amp capacity. Solution: when all is said and done, these solar panels that I am using are some of the most widely purchased panels on the market. I am fairly certain that there will be many people that run into this problem. I hope that this is a problem that could be fixed with a software update by rearranging the limits of allowed input voltage and amps. I would really like to see a feature in the software that would let you make this change very similar to how we can currently adjust the AC voltage input. If there were a way, in the software, for me to slightly increase the solar voltage input and thus lower the amp input at the same time, this would fix the problem and should still keep the delta well within its input capabilities. I hope this finds its way to the correct team and I really hope to see this change in the near future. I am very impressed with the ecoflow brand and engineering.

Have to say,.. Kinda of jealous you have have all that battery storage. Thinking you got all them free from your YT channel. Good thing I like your channel. Your DIY info is so valuable. THANK YOU for sharing!!

[@charlesblatchley]

im glad ii went with a lycan 5000 for my van instead of the ecolow delta pro because of some of the issues you went over.

[@KaceyGreen]

@3:18 the latest firmware has a labs feature in the app for AC always on, does this do what you want? I've turned that on because the description sounded like what I wanted

[@WillProwse]

Just found it, and didn't it see it till I updated twice. Doing discharge test now. I hope it works 🤞🏻

[@KaceyGreen]

@@WillProwse awesome! Hopefully so because I haven't tested it but it's the way I want it to react. On the Facebook Group or your forums (can't remember which) someone suggested it was only AC sourced or DC sourced but that didn't seem to make sense

[@MaxCaud]

Agree the inverter not turning back on when reaching minimum SoC is super annoying.

[@GR8Tmate]

Great episode Will 👍

[@dylanzimmer2614]

What do you recommend for the cheapest way to max out the solar for the Delta pro? Their 400w panels don't seem worth it to me.

[@wintersoon]

I'll just take getting close and within the 1600 W/150 V/15 amp specs. I've been looking for an answer for quite some time now.

@DIY Solar Power with Will Prowse I hope you are able to evaluate the new Ecoflow power kits when they release! I finally have enough money to invest in my battery/inverter/charger, and I was actually going to order the Delta Pro this week...but then I saw the new kits on Ecoflow's website. Of course there are no prices...but I guess I'm going to wait a bit longer before I spend my money. Thanks for the long term review!!

[@kylenewlin1944]

I like the idea of the power kits. (We own a small rv and a LARGE generator that we lug in and out at each stop to run the AC) but the cost is so crazy… I assume the same will ring true for the power kits. I’d love the idea of a 6500w EG4 and a couple of the EG4 WP… which would be far superior and more capability… oh and cheaper I’m sure.

I’ve been using two Delta Pros with a double voltage hub to charge my Fiat 500e just fine. Used an EVSE that’s amp adjustable at 24amps/240volts and works flawlessly.

[@JonathanBaileyn2u]

Thank you for your continued research on today's electro-tech.. I know this video was 2 years ago.. did EcoFlow ever listen to "us" and update the firmware to turn the Delta series back on, after recharging itself?

[@dominique___1980]

I have been using my DP + 1EB 24/7 for 2 months now. I agree with everything you said here. One more downside, even with the firmware and app updates, they charging and discharging of the DP and the EB is still quite uneven. Sometimes my DP is at 85%, while the EB is only at 40-50%. I know EcoFlow is working on that, but it has me wondering if I should sell and build my own system. Double that with the shutting down, but not automatically powering up when batteries are charged, and I'm REALLY thinking about selling/building. Thanks again for a really good video, Will.

[@陈志雄-h5e]

QIANSON QX3600 is the newly developed large-capacity energy storage power station, with a capacity of 3600wh, an output power of 3200w, a charging speed of 1.15 hours, and a unique "core" separation technology, and its volume and weight are only half of similar products. Amazing new product Buy a whole machine, get four power supplies

[@GotToyota]

Do you recommend these over the Bluetti AC300? Personally I like how the Bluetti stacks for space savings and the fact that you can use their Smart Panel to tie it into your circuit panel for backup/grid-tie power. Also not sure if you mentioned if the Bluetti can charge an EV or not.

[@Dickie2702]

Thinking of putting one of these in my camper. Saves putting is seperate MPPT and inverter. Can they be charged from the van alternator and or an AC hookup. I appreciate you are using this in a fixed location but I'm sure you know the answer. Great channel I love it!

[@robertharrison2144]

Great video Will. You referenced your blueprint on your website for the 48V system. Would it be possible for you to have a blueprint for just one of the EG4's instead of with 2. Thanks again, love the videos.

[@carrottop3454]

He Will. I think it has the auto turn on feature you’re talking about. Go to the cog wheel for settings. Under “lab features” there is a switch. Click on the little question mark in the circle for a description.

[@Paladin_Strategic]

That's correct. It automatically turns on upon either solar or AC input.

[@dlbracer56]

Always informative

[@dvdinjp]

Thank you Will ~ Great tutorials

[@winstonsmith935]

Neighbourhood doesn’t know it has a backup solar power Station on its block. Always said Node Power Stations is better than a large distributed grid system, with a single Power Generation. I’m retired from Canadas largest Energy Company. One of our Oil Facilities has Six Gas Fired Co- Generation Plants, the excess power is sold back on the grid to the Provincial Power Company.

[@speedracer9132]

I’d love to know if you’ve found a solar/battery setup that could run a super c RV overnight? The new eco flow power kit looks very tempting but I wonder if the full 15kwh system could manage to hold enough power to run two AC’s and a residential fridge overnight

[@mrpad0]

I agree with all you have noticed with this Ecoflow system. I have two Pros and 4 batteries.... and am now running the Ecoflow Home Panel to supply supplemental energy to the house (and for grid downs). One thing I have not seen covered is Kwh tests. Have you done those? I am finding that this complete system when everything is fully charged (2 Pros and 4 batteries) is giving me just about a THIRD of advertised use-time. I now have to check each Pro separately, and the batteries too (could take some days) but the advertised 21.6 Kwh is nowhere NEAR being reached. Power runs out at less than half of this. Have you (Will) or others noticed this? To me it's a biggie. If the grid goes down, this set up will last less than HALF the time it is advertised to last unless solar is input (I live in Ohio so that could be an issue without a hot-line to God) or the Ecoflow gas generator is used. 21.6 Kwh when two Delta Pros and 4 batteries are charged up suggests to me.... 21.6 Kwh. I'm getting half or less that that. The Home Panel tells me how much has been drawn. Have you checked the Kwh claims?

[@theageoftruth4005]

Have the exact same problem and it is weird noone raised a flag for that. Have a main unit and extra battery

[@mrpad0]

@@theageoftruth4005 In my case it was a matter of poor calibration. The units and batteries would read 0% but then keep running things for hours (!) I ran everything down to complete 0% and then recharged to a full 100%. That reset the calibration and corrected the issue for me.

[@johnflynn9510]

Will, I noticed a huge safety concern with my unit. If I have the AC connected and charging, the unit will pass through the AC power to the loads. I ran a toaster and a microwave and the unit was pulling 22A from the wall. The AC charging cable that came with the unit is only rated for 15A. Furthermore, the current seems to exceed just about any common household circuit of 15A and even larger 20A circuits.

[@jessematchey4802]

Is this a defective unit or a design flaw?

[@johnflynn9510]

@@jessematchey4802 It seems to be a design flaw. I tested more and it allowed me to draw 25A briefly before my 20A breaker tripped. Many household circuits are not designed for over 15A current.

[@StarboardBow]

Will cant tou turn on the units when the solar charges up with a bluetooth app or something?

[@RichardSwift]

As usual Will, great review. That shelving unit you have is great! Can you add casters to it too?

[@neilwolstenholme6075]

Have you looked into Settings > Lab features > AC Always on "In EPS mode, if this switch is on the AC power button will be turned on automatically after the power is back........."

[@WillProwse]

Is that with solar charge controller or AC input only

[@captmichel8035]

Great video, sure is helpful in making decision on which system to buy. Ecoflow is very attractive but definitely limited power wise compared to the DIY. Thanks so much for all the great infos With a 10 min of your videos we get more and clearer answers then the manufacturer. I want to use the EC DP like an ups 220v. Any chance to get detail infos on how to connect a separate battery bank (different brand) to the Ecoflow. And to use 2 delta pro 220v so we can run the well pump. Are we stuck having to use the wall unit they offer or is there a way around that.

[@djstraylight]

The Ecoflow Delta Pro ecosystem looks really interesting. How much power can you store with one main unit and two external batteries? Also any plan to review the Ecoflow Smart Home Panel? A fair criticism on the inverters not turning back on after being depleted and then charged by solar (or external AC). Hopefully they will fix that in a future update.

[@lucthien601]

each unit have 3.6KW so 3x 3.6 = 10.8KW ( 120 volt ) you need 2 main unit to get 220Volt out put .

Would you please do a review of the ecoflow delta pro ultra. I'm leaning towards getting this in Jan when it comes out but and concerned about longevity and availability when comes time to replace parts in the future over building a system from components that when comes time to replace/upgrade i simply replace each component as needed instead of being stuck buying ecoflows next system.

[@williebechmeister3190]

There are conflicting reviews and comments from Ecoflo tech support about leaving the delta pro solar input plugged in at night. The acceptable voltage input range is listed at 11V - 150 VOC. As I understand it, solar input falls to 0 if solar charging is less than 11 volts (40 watts) because the inverter requires at least 40 watts to operate. So if the solar input remains connected in low light the unit starts clicking on and off as it attempts to charge, but cannot because the solar input voltage is below 40 W. One response from tech support says the solar input must be unplugged at night to avoid damaging the battery, another response says there is no problem, ignore the clicking. Anybody have any idea which is the correct response? Seem that if there is a problem with leaving the solar input connected under low light, it could be corrected with a firmware update.

[@jonjohns8145]

Hey Will, How are you connecting the server Rack batteries to the EcoFlow? Is it just an XT60 connector to the EcoFlow's MPPT input? I have been very curious about how to extend the capacity of an EcoFlow or a Bluetti system with Rack batteries (instead of the more expensive expansion units) but I was not sure if it safe to hook up a battery through the Solar input of either of those systems.

Is it a potential safety problem with Solar Generators, that they 1) Are not grounded? 2) Do not have built-in Circuit Breakers? I mean, nowadays, Solar Generators are getting increasingly more potent and can carry residual currents of some magnitude, I guess?

Great video as usual, I do have the eco-flow Delta Pro with the two backup batteries. I can charge my Tesla off the 30 amp (using a ground plug) but I haven't tested using the 240v.connection. what happens when you connect it... wouldn't the ground plug make it work?
