Got my 2nd A48100 installed yesterday but seen some worrying things.
perhaps anyone of you that have a solis and multiple Dyness can share?
the master battery , all lights blinking constantly. After a reset, the master battery wakes up the slave and lights look ok, but after 1 minute the blinking starts.
BMS reported 50A max discharge , rang Solis and they had 100A. Had to restart the batteries and seemed the 100A now ok, will try later electric shower to confirm.
also, I am getting a constant 140W discharge reported with the 2 batteries overnight. With the 1 battery this was 190W. However there’s nothing plugged that consumes that much!
those wats consumption disappear as soon as there are around 100W coming from the panels and batteries charging, but come back after battery charged.
installer doesn’t seem to know
I’d appreciate any help, please
pic was taken Sunday 16th, very cloudy. Only fridge in. Nobody home all day, holidays.
every day is the same pattern, 5kw consumption on a fridge that should do max 0.8, nobody at home

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?

Did a test here. Mains off everything besides the inverter Kept on.
before that it was using 150W, after, inverter on “standby” seems to be sucking 70W
in theory , these inverters shall go 15W in standby. So there are 55 wats not accounted for.
will check Solis Monday and figure out what’s their take on it.
Correct me if I am wrong. If there is no solar controller or anything to avoid the issue and the panels are drawing 55 wats on average 12 hours a day (when there is no voltage) over the year is 660 wats a day. Total 20Kw a month. 240 Kw a year. Around 100€ at 40c kw
I’ll test tomorrow during the day when the batteries are charging (all the other mains off besides the Pv system) and confirm what’s the inverter displaying as consuming on top of the battery charge.
below. Pitch black outside. All mains off besides PV system. 70 wats usage of inverter.
if anyone knows better, please share!

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)

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 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!

I just have the 2 batteries. I see what you say.
Guys, would it matter or is just good practise? I wouldn't want to ring the installer for something that wouldn't really matter.
See 2nd image:
Seems that is also good, right?
Also... seems it doesn't really matter, just etiquette? Found other one.
My main issue here lately is the overnight discharge below SOC when there's no solar coming in. I am testing different % thresholds with the Solis to see if I can figure out the right combo.
Based on the documents shared here officialy from Dyness, can you see they recommend just 5% of SOC and 5% of force charge?
However the Solis goes to 20% and 15% as default. Some recommend other values, seems all so different. If I had to go with smtg I'd go with the battery manufacturer. At the moment testing 12%, 11% and backup ON to 11% (not allowing backup charge) to see if I can remove the glitch of 62w constant draw overnight when the battery under SOC.
I have the Solis S5-EH1P-6K-L and the 2x Dyness A48100

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 manual does say to connect it like that alright:
It makes a difference when you have multiple batteries as the SOCs won't be consistent even your man Will Prowse demonstrated it but with just two batteries who knows. Installer should have wired it as per manual anyway.
You should NOT disable grid charging or you risk letting the batteries go down to 0 and damage them.
Dyness advised to not go below 15% but you can go to 10% SOC

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 !!!
