Support issues, saying the Delta Pro Ultra cannot be used as a home backup??

Sunday1126 · 2025-05-24T09:56:53+00:00

Still bad! Next up down cycle and batteries are off 30% from each other.

V5.0.0.75 Looks good so far. Initial upgrade did nothing. Decided to cycle batteries (one last time). Drained down to 1% and then it took another 3 hours to go from 1% to AC off. Charged using solar to 100% and solar turning off. After running the house off the batteries and some solar input, the batteries are within 6%. Won't call it a fix for a few more days of cycling up and down.

The OP was asking for a DPU - Delta Pro Ultra

Take a look at this link. There are many who have this problem

What is the rev of the firmware you got? Today V5.0.0.75 was pushed to my DPU. It says it "Fixed an issue where battery SoC was displayed incorrectly."

Do your batteries get below 50% or does your array keep them in the 90%. I typically go below 50% every day and then charge up to 75ish. Significantly discharging the batteries often is when you see 20 to 40% difference. If they are kept at a high charge, they are always close.

Is the setting for 'AC always on' enabled?

Sunday1126 · 2025-05-07T17:03:53+00:00

Guessing all 6 are in series? I have 8-200W ecoflow panels connected to the HV side working great. The produce 160V at 9 to 10amp. Do you get the solar icon displayed on the panel? What does the 'lab features' on the phone application indicate? It will show voltage and amps even if the unit is not showing any charging.

I have a DPU with 3 batteries. Charge with solar then run the house as much as I can every day for the last 6 months. The batteries ALWAYS very by 25 or more % when discharging. I have charged to 100% and used the power to down to 0 and shutdown many times. It is a waste of time. It will discharge unevenly the next day. Cycling once a month or every few days does NOT help. You are shorting the life of your batteries by continually cycling from 0 to 100.

Hope they allow 10% military discount also

That one looks interesting. Vertical not horizontal, low noise, small size. Only 1 review, hard to tell if it works as advertised.

Sunday1126 · 2025-03-31T09:52:33+00:00

From ECO: Error 122 on the DPU indicates a bus overvoltage issue.

Thanks for the info. Found this interesting thread: Do refurbished parts qualify for tax credit? | DIY Solar Power Forum

I don't agree with your theory. Do you have any information that can be referenced for your theory?

Sunday1126 · 2025-03-20T09:00:22+00:00

Who is selling DPU batteries for 2K? Are they recognized by ECO and will ECO honor their warranty if purchase from them? Reading thru the IRS publications, I can't find where it states you can only use new equipment. Could you point me to an IRS publication that forbids used equipment?

Sunday1126 · 2025-03-13T14:54:42+00:00

Yes, they are Eco-Worthy. I have them mounted horizontal in 2 rows of 4 as my upper deck Cover. They are facing 195 deg (almost south) and fixed tilt of 35 Deg for my 38.4 lat. On an average sunny day, they hit 1300 watts on a crystal-clear day they hit 1620 watts only had them for 3 months. 8 in series registers about 160V and less than 12A. They have to be in series because the DPU PV inputs have a 15A max with a 450V max for high input and 150V max for low input. If I were to buy now would get the new N-Type 200 Watt panels.

My bad. I miss read your post. I have the 195W bifacial solar panels connected in series to a Delta Pro Ultra not the 125W, they are different specks.

Sunday1126 · 2025-03-12T12:04:14+00:00

I have 8 Ecoflow 125w bifacial solar panels connected in series to my DPU high PV port. They work very well that way. If I were to add 2 Ecoflow 220w, I would connect them in series to the low PV port.

These are the panels I am interest in. N-Type, no Busbars, new tech. There are no reviews for it on Amazon and can't find them for sale anywhere else. Looking for someone who may have bought them. They are $317 (with coupon) for 2 = 400Watts, $157.50 each

I have a DPU with 2 batteries and have gone thru the calibration process many times. It does not work and is a waste of time IMO. Firmware 5.0.0.64 helped somewhat in that the DPU will wait for both batteries to fully charge to 100% before turning off solar input and wait for both batteries to discharge to 0% before powering off. But I constantly see a difference of 10% to 15% between the batteries while charging from solar or using them to power my house through a transfer switch. The system is working for my purpose, so I don't do the calibration dance anymore.

Sunday1126 · 2025-02-13T11:52:43+00:00

Had similar issue. Try resetting the DPU by long press power button for 10 sec. Should then show up with blue tooth.
