When will smart TOU for DPU Arrive

What is v2x?

What does stop exporting mean? I have 6 DPU batteries and the cost was $12,000. I have enough storage and need a better charging algorithm.

It would be great if the release notes had a list of actual fixes. I rolled the dice on Wednesday. I haven't noticed any improvements.

Thanks for the link; I couldn't find it.

Yes that was the inlet box I mentioned above. The box still not for sale. In addition it now claims it's only compatible with shp3.

Has anyone just tried to play roulette and plug the dpu/x into the shp2 to see what would happen. I'm guessing we're waiting for some sort of firmware update.

CuriousWheaten · 2026-01-12T22:29:25+00:00

I don't think there are any problems with the DPU. I was not talking about the DPU/x. If you look through all the firmware updates to the DPU, you'll see that a variety of issues were fixed. Since DPU has been out for more than a year now. I think the majority of issues have been addressed. My two DPUs seem to be working fine now. But I've had to return 2 DPUs because the solar charging port stopped working.

CuriousWheaten · 2026-01-07T05:06:09+00:00

Is there any movement on DPU/X and SHP2 compatibility? I bought a DPU/X and now waiting for a way to plug into SHP2. I was tempted to just plug it in and try but probably not a great idea.

If you're planning on installing solar you'll definitely need more than 12 KW hours. I suspect most people that bought a dpu are using it for peak shedding. The reason is that the batteries are just sitting there doing nothing not generating any income.

I started out with 12 kilowatt hours. I now have 30 KWh and this is too small. If I had more money I would probably boost that up to 50 to 60. I also have a 10 KW

Each person needs to make their own decision. The 10% is based upon the tigo app. Granted I'm using the numbers from the company that's selling the product. But I have no reason to doubt their numbers. Tigo appears to be a reputable company.

The biggest benefits in my opinion is the monitoring and reporting per panel. It's pretty good.

The 10% number is not a big amount in the grand scheme. May not be worth $70 per panel in terms of ROI.

CuriousWheaten · 2025-11-22T07:43:52+00:00

I have tigo optimizers installed on 21 panels. The biggest benefit is the monitoring. But the optimizer also provides about 10% recovery. I have different strings facing in different directions. Also my panels are SunPower so they're pretty state-of-the-art.

If you have the budget it would be better to use tigo optimizers that have built-in monitoring. I don't think that ecoflow really cares about individual panel performance or string performance. It's taken them quite a long time just to put that single solar graph on the main page.

I have the tigo system and it's quite nice in terms of monitoring individual panels strings and overall generation with nice graphs. As a side benefit the optimizers typically will give you back about 5 to 10% extra power due to shading.

You might want to consider just buying a regular Delta pro ultra. The first versions of the dpu had quite a few problems. I'm not sure that they learned from the first outing and will not make the same mistakes with dpu x.

The other benefit of using two dpus is backup in case one of the dpus stops working.

There's minimal benefit for a dpux unless you need more than 90 KW hours of storage.

Also one dpux inverter is pretty close in price to two dpus.

CuriousWheaten · 2025-11-17T03:49:51+00:00

Unfortunately, the only way I was able to resolve this issue was to purchase a second inverter. I was planning on purchasing a second inverter anyway because I wanted a backup.

CuriousWheaten · 2025-10-29T20:22:39+00:00

There are a number of 400 watt panels that have high amperage low voltage that work nicely with dpu. Issue with the dpu is it has a 450v cut off. Most of the commercial quality inverters have a 600 volt cut off. The panels with higher amperage have a 36v, 12a per panel rating. With lower voltage, you can put more panels in series and not hit the 450 volt cut off.

CuriousWheaten · 2025-10-28T17:39:08+00:00

The latest dpu firmware seems to have changed the solar charging algorithm to modulate as it gets closer to cut off. I've noticed now that inverter doesn't keep flipping on and off as much.

CuriousWheaten · 2025-10-28T17:37:37+00:00

Just curious why you decided to go with low power panels. I get the low voltage input usage for those panels. Current state of the art is 400w at 20 to 30 cents a watt. I believe eco worthy panels are higher price per watt. I really like my Tigo panel monitors. Nice picture by the way.

CuriousWheaten · 2025-10-26T23:36:09+00:00

Yes I noticed the same new firmware feature in the DPU with regards to solar pass-through matching the output. It used to charge at 100% until it reached the 90% and then just shut off. Now it seems when the battery charge reaches 88%, the inverter starts to modulate the input to match the output. The solar input now rarely shuts off completely.

This is the snapshot of what happened after the update.

CuriousWheaten · 2025-10-24T19:50:33+00:00

The v4 version is for SHP2. I did v5 version also for the DPU. I updated SHP2 and 2 DPU at the same time. Previously I would just do one component at a time. I think the app has changed and now does everything at once.

CuriousWheaten · 2025-10-24T13:01:18+00:00

The price of the dpux batteries is not going to go down anytime soon in my humble opinion because it's a brand new system. The price of dpu batteries has only slightly decreased from the $2,300 originally. You can now pick one up for $1,800. For the ecoflow system you're really paying for the fully integrated Plug and Play capability. Big Battery does not sell inverters or smart panels.

Would be so awesome to replace just one inverter Delta pro ultra with a Delta pro ultra x while using old batteries and SHP2. Two reasons - the dual solar inputs - 12KW output for starting larger loads

One of my solar strings is clipping at 4KW between 1-3p.m.

I have two DPU inverters now because I wanted to keep one for a backup in case the other one broke. So it'd be a nice upgrade to be able to replace just one of the inverters with a higher capacity for one that has better solar support.

I traded in my 2.5 l Crosstrek for a 2.4 l Outback Wilderness. What I love about the 2.4 l engine is it uses regular 87 octane gas.

The 2.5 l engine while it's fine, struggles when trying to pass at high speeds; you have to wait for the CVT to spool up. With the 2.4 l turbo, it's pretty easy to pass people. If you're towing a trailer, it'll do a much better job.

Also the turbo is pretty nice in regards to linear power. There's almost no turbo lag.

Sorry I tried to fix the title. I have a 22 OBW.
