What does it say on the front of the battery. Which inverter are you using them with and do you have them working in Lithium mode with communication or have you set the voltages manually?
December 30, 20232 yr @PsyCLown Hi, Hope that you had good Christmas. I have 2x Svolt batteries that I purchased and a 5 Kw ECCO inverter. I am using it as a standalone UPS and it is working great. I have been unable to get the BMS to work and currently using voltage setting. I do have the dipswitch 1 set for master on one battery. Inverter Option 05 - battery type LI 2 supports PYLON US2000 but BMS does not connect so I would like to connect to the battery using RS232 and verify the protocol settings on the battery. May I ask where you purchased the RS232 cable so I can give it a try with PBMStools. Much appreciated

The cable was gifted to me, it is a RS232 cable with a USB adapter.

March 13, 20242 yr Hi, Thanks for the information. I also have two of the 51.2 V LiFePO4 batteries. Lets call it Battery ONE and Battery TWO. Its a 48V system, I have connected this in parallel and is working fine. I have a question. How to connect the network cable to the BMS panel of the inverter. Also there are RS485A, CAN, RS232, RS458B ports for SVOLT battery. 1) Where does the inverter to the Battery ONE connect to for Inverter to Battery communication? 2) Where does the Battery ONE connect to Battery TWO for Battery to Battery communication? May you please assist....🙏🏻🙏🏻🙏🏻

Otherwise I can take some photos tonight showing you with my batteries how to connect the batteries in parallel for BMS comms.
April 3, 20242 yr Hi Payclown What is the address & tel no for Svolt Johannesburg office? I cannot seem to find this information anywhere thanks
April 9, 20242 yr @PsyCLownThanks for the write up. I also intend to purchase an S Volt battery though i am not in SA. My interest is in remote monitoring. Is the raspberry PI reporting reasonable SoC for the S Volt batteries?

I monitor the SoC via my inverter in Home Assistant - so inverter integrates with Home Assistant (running on a RPI 4) and I can monitor SoC via the inverter. I am sure there are other ways, but for me that is the easiest and its good enough.

Is the raspberry PI reporting reasonable SoC for the S Volt batteries? I have 2 setups with a Pi monitoring the batteries via the RS232 port (I just use a MAX2232 module to do the TTL<->RS232 level conversion, but the USB<->RS232 devices work great too), using https://github.com/Tertiush/bmspace. Works great, and goes into home assistant. I've also gotten PBMSTools to work remotely with ser2net to read out the logs which was helpful. They're standard PACE BMS's though, so anything that talks to Hubble/Revov/SVolt (and many, many others) etc will work.

And is it only for monitoring or also can change some parameters (settings on the inverter)?
April 25, 20242 yr Hi Rou I used the app SmartESS and you can access it on the Web or your phone. Both Web and APP allow you to make changes but I have not tried. Too scared lol :).

I am considering buying the same and would appreciate some advice. By the way, do you know of any WhatsApp (or Telegram; Viber etc.) support user group for Ecco? Thanks!

May 2, 20242 yr @Rou I have had my ECCO inverter since September last year with no operational issues. The only issue I have is that I can't get the BMS to work to my SVolt batteries no matter what I do. I have given up and stuck to voltage settings and all works well. I do find a drift with SOC on batteries but don't think that is related to the inverter. I just run batteries down every second month to get SOC back to normal on batteries. If I could go back in time I think I would have chosen the LuxPower as it is similar in pricing (a little more) and has a generator input which becomes a shlep with ECCO in that every time you want to charge the batteries with Generator, you need to go into setting and change the input. LuxPower seems to support more batteries and has better support from what I can find. ECCO is difficult to find much, just my opinion. Hope this helps in your choice.
May 2, 20242 yr @MarkHoskingsas a matter of interest, have you been in contact with the SVolt rep to ascertain if they have a CAN or RS485 protocol suggestion to get their BMS to communicate with the Ecco? I suppose one would need to establish from the Ecco distributers what protocol they use.

Thank you very much @MarkHoskings! I made 2 days ago the mistake already- bought the Ecco 5.5kw with SVolt 5.43KWH. But I have a communication with the BMS of the battery- one good thing Managed to set up the SmartESS to work and so far looks OK. Will see how it goes.. Edited May 2, 20242 yr by Rou spelling
May 15, 20242 yr Hello, I need some help please! I have a backup system ECCO 5.5KW with a SVOLT 5.43KWH battery just for only 2 weeks. The BMS is communicating with the inverter (under LI2 - Pylontech). All seems to be working well - the battery was staying at SOC= 99% until 3-4 days ago when I noticed that the battery went to 98%. Then after a day went to 97% and now it is at 96%. Yet it is permanently connected to the grid. One other thing I noticed is that despite the SOC goes down as percentage, the battery voltage stays at 56v. What could cause the SOC percentage to drop like that while the battery voltage stays at 56v- could it be that the bms is doing some equalizing of the voltage cells and some recalibration.. Or is it the worst- faulty cell? Thank you! Edited May 15, 20242 yr by Rou add pics

Switch the utility in that feeds the inverter off at the breaker and discharge the battery to 50% soc switch the breaker on and let the battery charge. That should reset the soc back to 100% or 99%. Edited May 15, 20242 yr by TaliaB
May 15, 20242 yr @TaliaB thank you! I actually discharged yesterday the battery but to 75% and then switched the feed on again and it charged it to 97% and that's whare it stopped. Today around lunchtime it dropped to 96%, yet it was all the time connected to the grid to charge.. I will follow your advise to discharge it to 50% and then will switch On to charge it. Hope that will make difference.
June 15, 20242 yr @PsyCLown I wanted to find out something before i buy. There are units currently being sold which dont have BMS communication with inverters. Any work around such?

I think you are referring to some of the 24v Svolt batteries, they have a BMS but there is no BMS communication. I am not aware of any work around, other than possibly trying to replace that BMS with a different BMS - I do not think it is worth the effort and cost though. You'd also void your warranty if you were to do this.

What could cause the SOC percentage to drop like that while the battery voltage stays at 56v- As it affects the durability of a battery sitting at 100% and not used many BMS will discharge as soon as it hits 100%. Not saying it is in your case. As per the reply from @TaliaB discharge to 50% and check again. 1% is only 150Wh of over 5400. Don't worry to much about it. My own view.

There is no bms comms so the inverter should be set to "Use"( program 5) then you can set bulk charging voltage to 56v. ( Program 26) and float charging 54.4v(program 27). Because you do not have bms comms to the inverter it could be the inverter is interpreting the Soc incorrectly. 56v is a full battery i won't worry to much about the Soc displayed by the inverter. If you want an accurate Soc you can fit a Victron Smart Shunt.
