Dyness A48100

About to have one installed tomorrow to replace a 20 day old faulty Puredrive ..

Posting sources and prices is ok for batteries I think.

The issue is with installers , we didn't want people bashing them in threads.

Thanks, yep makes sense.

Just wondering a rough price to have an idea and run some calcs.

Checked and yeah, online you can find them but are South Africa. We wish we could source them here at those prices on the web lol.

I've asked them for price of battery and costs of delivery to Ireland, just for the sake of getting a number as the A48100 is not listed their site.

Cannot confirm 100% on reputability by site looks legit, and I can read all the Spanish remarks.

Update: they have just replied (very efficient): "they only work the 51100"

I have a Dyness PowerDepotH5 - looks a LOT like the PowerBox Pro... mine is 4.8Kw size.

I have used these settings for a year no issue:

Overcharge SOC: 12%

ForceCharge SOC: 10%

ForceCharge Limit: 50A

I would be interested from the experts to see if I should adjust - but i am happy with my performance so far and dont want to break it! :)

Wouldn't that ~200W be your baseload? Like fridge/freezer, standby devices, modem/router etc.

Also, when battery is fully charged also does it… only time it doesn’t happen is when the battery is been charged.

Mmm, not sure you get the question here. The Solis inverter consumption is 10W.

During the day, the *consumption* of the stuff in the house would go from a minimum 40-50W, router, inverter, couple of minor standbys, to 90W when the fridge is on. That's all when all is off.

When there is no sun hitting the panels and battery is not charging, the number I get is a constant 145-150W consumption.

This sounds to me the panels are draining energy out as it is not consumed by anything else. You are talking 100W that cannot account for.

How does that explain then that a house without anyone on it is consuming 5Kw daily just with a 260Kw/annum fridge (~0.8 Kw daily) and a router that adds other 30W per hour ~0.7Kw?

Sounds like tops is 2Kh a day, this thing is sucking more than double.

Those 5-6 days only purple are days we weren't on the house. Total 5Kw daily, same pattern as the daily screenshot posted above.

Is that normal for you too?

Thanks. So you could account for that 120 to 150w overnight based on what you are currently using in the house?

Why would my Solis web image display no house consumption or under 100W during the day and battery charged, and then 145W-150W flat and constant overnight to then disappear once sun starts hitting?

Am just trying to figure out things here, thanks for the help.

Nope. All unplugged while we were out.

how are your daily charts in any day you were on holidays? Same pattern as mine ?

If you have the same Solis setup that would defo say something.

if you have an overnight line constant wats usage over 150w like me then I would take it but I am kinda inclined to think is something like this:

https://solargearguide.com/do-solar-panels-drain-at-night-weve-got-the-answer/

I don't think is anything I have plugged. Or there is a power draw between the solar panels and the inverter that is not reported on the Solis Cloud, or Solis cloud is reporting the consumption on a different way when there is solar power coming in or not.

Can't be my house sucks 5 Kw daily on a fridge and 150W constant overnight and below 100W during the day when the same stuff is plugged!

See below for comparison, as you can see the battery drain is always more than the house load, up to 200w, I doubt that's just battery loses, must be the inverter using a big chunk (70w is too low I think)

House load

Battery load

The other way around actually, that is the inverter one, BMS power value is lower, up to 100w less.

Thanks for the comments ! Right now I can see on the app 135W that makes total sense with that is plugged in the house and 70W for idle Solis, where 15W is what I’d expect for the idle inverter and 55W not sure what’s the gap. I will be testing tomorrow during daylight the same thing, turn all off from mains but not the PV and see if those 55 appear anywhere or what. Some should appear as the Solis won’t be idle but charging battery, however:

if my suspicion is right, it will confirm the panels do draw 55W when battery not charging. Will also ask the Solis support and share here the results.

70W for an idle inverter sounds too much.

anyone with a charge controller? Aren’t those meant to avoid the panel power draw overnight?

Hmm I asked about wifi on existing batteries and they told me if they are not specced from the factory to have wifi built-in then you can't add it at a later stage.

They didn't say anything about this thing but I believe that is confirmed in the manual:

No wifi in the battery then it won't work?

A bit stupid if that's the case, if it has a wifi module in the battery then why do you need this thing?

I think you are right just seems like an rs232 wifi adapter that just works with their app/send data to their cloud.

I actually have windows software they sent me that can do the same but I never got around to making the COM cable and test it.

Here's what they sent me if you want to play around with it.

Let me know if you get it to work, could be handy for investigations 😀

Or hooking this up to an rs232 wifi adapter and then bring the data into Home Assistant.

I got my issue fixed. Seems there is a batch of A48100 (sourced in Ireland) with a firmware that is not letting them talk together proper.

Sharing details here, as this should help a lot of people with the A48100 if you are affected by this when having more than 1 battery.

You have to wait 20 seconds to a couple minites of starting my 2 batteries, the video attached a few posts ago shows the master battery with all LEDs blinking at the same time after reboot and that time lapse. Dyness support quoted it as "Internal communication problem"

After a few days and sourcing the Dyness Wifi module http://www.dyness.net/uploadfile/file/20220513/afa6eaa7edf22b52226412fd6101c79c.pdf

I couldn't upgrade any firmware... however, after contacting Dyness they uploaded something somewhere and the iOS app connected to the WIFI dongle and the battery was prompting to upgrade to the "1.07 Ireland" version.

You have to remove all the other communication cables from the batteries. Set the battery to update as master DIP 0010. Do all the batteries. Then, turn all off, setup the DIP on the master as 0010 and all the other batteries as slaves. Start as normal, everything will work as expected.

Finally working with 100A charge/discharge and no weird lights.

Forced charge to 100% to balance the batteries and you can see it was already charging at 100A (and also used for the first time the Solis 6Kw inverter fans!) :) See dongle to the right of the pic.

This is from the iOS app, if you search for "Dyness" you can install it but can't do nothing unless you have the wifi module.

the module lets you monitor the battery independently of the inverter and also apply firmware updated. perhaps just a one use device but did the trick for me.

Contact Dyness support if you in doubt. info@dyness-tech.com they were very helpful.

Might take a while to start to be contacted but after that they will move fast.

For this question about this A48100 battery, to setup on the Solis Menu:

The recommendation from Dyness support was:

"As far as I know, this does not need to be set. Only when the lead acid is used, I need to set it. "

So, defaults are good.

Also attached the doc:

Very happy with Dyness support.

You might have no issue with your battery but you’d know what to look for if you get one and that support will resolve. So far very happy with them.

Hope it helps!

On the app itself yes.

You can use both at the same time.

The battery has 3 ports. IN/OUT used by inverter or to comm to other batteries.

The other port called COM is a 6 pin one, that's the one to plug the dongle into.

Will send you PM , but it was expensive as ****

Note that, if you have to upgrade your firmware, it won't come up on its own, I had to engage with Dyness support and send screenshots of what the app was telling me as ID in order for them to make the update available for me to apply...

Cable is included, says it in the manual

will pm you details

Will do share now.

Contact Dyness support. You will also need their help for them to make the firmware available to you. Seems is not universal and doesn't appear.

I might be wrong, would be good to know here once you get it sorted.

That's just good practice in a large array. Short (pardon the pun) of using two large busbars, you should always have the positive and the negative main connections at opposite ends of the array

I had my threshold in 18% and force charge 15%

Overnight it does suck up constant 62w from the batteries if 18% or under, when it shouldn't.

This has to be some firmware thing, it shouldn't be doing that. Managed this morning to get it to jump to 18 and it did stop, this is bothering me :(

Every night is the same thing. The point is the base load is 75-120W based on how the fridge is doing.

The grid charging seems it has its own setting for Backup mode, so you can set that separately only for backup.

You say:

"Dyness advised to not go below 15% but you can go to 10% SOC"

however, if you see the document from where you get the image, their settings say 5% and 5% with a DOD of 95% allowed for these units.

Confusing the least.

Agreeing with you it should be wired as per manual. Installers. :(

Would it be safe to remove the black cable from the Master battery and plug to the slave battery? How would you suggest to do that? Turning off batteries and/or disabling battery in the inverter itself? Would that be safe?

Thanks Dracula for pointing this out!!!

same guy that left the 2nd battery with the firmware issue did the cabling that way.

For what I read around, it does matter the connections unless y are using other types of batteries without BMS etc

Turned all off. Unswitched the safe and changed cables. Let’s monitor tonight the power leakage . Left SOC 15% and force charge 14%. Backup ON at 16% (not allowing charge for Backup). Hopefully this will be the end of it and never go up to the attic !!!
