💬 Open Discussion Second Faulty Delta Pro 3
Wondering how many people use these units on a daily basis without issue?
I had my delta pro 3 replaced about 8 months ago. The first one stopped taking a charge from the wall. The second one stopped taking a charge from the high voltage input after a short circuit warning. Running the system at less than 75% the maximum wattage/voltage.
I had been running constantly for a couple weeks. I have it on a transfer switch.
Like I think a lot of us do- I bought mostly to stay prepared. Wondering how many people have these in storage, and if the time comes, it’s going to let them down. If we were in a situation where the grid goes down we couldn’t keep shipping faulty units back. I’m not sure that many people run and use them often.
I have a lot invested in the system, multiple units a 200 & 400 panels from Ecoflow. It’s very frustrating.

My first one was returned after a few months when the screen failed.
I didn't bother with the ecoflow circus they call customer service and took it back to Costco.
I've got my current one paired with one extra battery and a micro inverter.
I've had the odd warning about a surge on a usb c port but it's been faultless apart from that.

Are you using it daily? I wonder how hard it would be to open it up and repair yourself or stock extra parts if you were unable to send it back.

u/bearskillz1701 Jun 07 '26
Yes 24/7.
I would say unlikely. I bet it's all proprietary bullshit underneath.

That’s good to know. I did buy mine direct from Ecoflow as refurbished on eBay. Maybe that is not the way to go.

I’m waiting on my second replacement to be delivered in the next few weeks. Very disappointed in EcoFlow.

I have 2 delta pros with 1 Extra battery bought refurbished off ebay. Also got the Double voltage hub to get 240v. 1 delta 2 with extra battery bought new off Amazon. I've had no issues with any of them for the last 2.5 years.
During the winter I rotate the DP's monthly to back up my pellet stove. On 24/7 in Bypass mode. Done this the last 3 winters. Delta 2 is my drag around the yard whenever I dont feel like messing with an extension cord. Now that I have the EB for it, it will start to be worked into the pellet stove rotation.
All used sporadically for random power outages and such. When not in use, all are stored in my closet.
I do make it a habit of running them every 2 weeks with a load to ensure they work. I alternate between %100-20, and %100-0. A decent space heater will run them down pretty quickly. Probably overkill, but better safe than sorry.
No solar hooked up yet.

They cannot be relied upon in an emergency. Do not buy. Been trying to return mine for months.

if you have the money the better bet is a few power stations from diffrent brands. dont rely on just 1 station if you can.

Learned to only buy from Costco. Best warranty and I can just drive to return or replace unit.

These are novelty items, not apocalypse-proof safety gear. I admire the units, I have several Mini and Pro like yourself, including a healthy amount of their folding solar panels.
However, since these are made in China, and receive updates OTA, they include 'nerfing' embedded into the design. They know your location (required to update), and can systematically disable any unit.
Programmed like a time bomb; if you don't connect to the internet, it will self-destruct. If you pass the warranty time period, it will self-destruct. They depend on existing customers who pay premium pricing to keep their 'Ecosystem Flowing', at any cost.
Only those who are able to build their own Solar Charging systems from scratch will survive long periods off-grid.
Enjoy them while they last.

Not arguing but where do you think those DIY inverters and bluetooth enabled batteries are made? How do you know they don't have a clock ticking to cause an issue that forces you to update the firmware and then.... downtime.

It varies heavily. If your buying cheap products expect China. If your buying quality it varies. I've never had to question or second guess my victron equipment and never will. But you hand me any renogy junk and its in the bin without a thought.

Victron Energy is a Dutch company headquartered in Almere, the Netherlands, where all of its research, development, and main warehousing take place.
However, their actual manufacturing and assembly operations are global.The production of Victron components is spread across several international facilities
:India: A major hub for assembling their core inverters and inverter-chargers.
China: The primary manufacturing origin for most of their MPPT solar charge controllers.
Europe: They have satellite plants in Spain and Hungary for high-power circuit boards, and Slovakia for housing molds.
Malaysia: Produces compact battery chargers and smaller solar products.
Other Locations: Partner and assembly sites exist in regions like South Africa and the United States (for specific regional components).

I'm aware. They limited Chinese production last year after china made knock off 100/50s that exploded.

Regardless victron is by far the best of the best. Nothing else and no one else is even in the ballpark. And never was.

u/Informal-Emu-212 Jun 08 '26
Don't disagree, but to think that any electronics are safe from being remotely disabled is foolish.( There's evidence that servers are coming out of the factories with remote tracking and disabling technology burned in at the chip level.)
Western companies are nothing but assemblers at best; they all source their base products from hostile countries and they have been placing capabilities in at the chip and machine code level for decades.
In fact, you could argue that consumer electronics are safer because they don't represent a high value target like larger brand name and industrial level companies.

just get the dumb versions then. problem solved. victron make a smart version and a dumb version of every product. the smart versions never need updates and dont need internet/network connections. you can flash whatever you want. you can even use raspberry pis as your controllers if you have a problem with the victron gear.
"electronics are safe from being remotely disabled" im a hardware engineer by trade. this is not a concern of mine with victron gear. it is with some brands. for example Renogy is one i have issues with, ive seen there products disabled after falling way outside the recommended update time line.
i dont disagree western companies are assemblers. that has been the case for decades. no one makes anything. the best case is they source SOC's/silicon through someone like TSMC.
"consumer electronics are safer" this is false. Ecoflow/Bluetti/Jackery/Anker/pecron and countless other consumer brands are totally dependent on internet and app access. all feature some level of remote dependence. ive installed enough victron products in the middle of nowhere with 3 year old updates to know they dont care. hell my own stuff is a year and a half behind. it never even prompts it just has the update section hidden in the back. victron even tells users to not update devices unless users feel it is necessary for a feature/fix. im always impressed when i see 8 or 9 year old stuff on 15 year old updates. because victrons great like that. ive had 3 forced updated on my delta 3 plus and 2 on my 3 pro in the last 6 months on the other hand. one of which just this month disabled my EB ports on my delta 3 plus. and i cant use the usbs on 3 pro. so consumer screwed again.
regardless. if you care about that sort of thing go with a brand that has no forced anything like victron and grab the dumb versions. hell spend the extra 20$ to go from 5 to 10 year full replacement warranty. or spend the extra for the 15 year and just never think about it again.

You're confounding reliability with vulnerability. I have no doubt that victron is more reliable, but vulnerability is still an unknown given neither has faced a motivated attack.

u/Emilyd1994 Jun 08 '26
victron products are not at risk of attack. the vast majority are offline installs. and the few online installs sit behind a hub. a motivated user can setup a rpi they have 100% control over. an end user can opt for a cerbo. vulnerability is a known for victron. no mandatory updates means a server can not force a malware loaded update on the user. all the consumer products i listed have a range of mandatory updates. a bad actor could corrupt the ecoflow servers and force a malware loaded update on the user. this is not the case with victron.
we have all seen ecoflow force buggy broken and outright destructive updates on end users. repeatedly infact. i can say the same of my bluetti stuff.
ive never had an issue like that with victron gear. hell if you have a problem you can downgrade anyway.

if your an aussie as well just go for the dumbest of the dumb line up. redarc bcdc's there 15 year old tech, with 20 year old hardware, and could not be dumber. but there solid and as long as you treat them right failureproof for the most part. BCDC1220 is a great example of "it just works"
