Hi

Great to see SVolt has come onboard.

I hope you can resolve a long standing issue I have with the SVolt 15S 5.09 kWh battery. When I bought the battery just over a year ago, the charging and float voltages were specified at 52.5 V and 51 V respectively. Problem is that it does not fully charge the battery, only reaches about 95/96 % SOC.

The battery is paired with a Growatt SPF 5000 ES and when in LI mode, the voltages are set at 54V and this sets off OVP warnings when reaching 100% SOC.To avoid this, I have resorted to voltage control settings under USE2 on the Growatt.

Now I understand the charging parameters have been revised to 54V charge and 52.5V float. I have been trying, unsuccessfully, to find out if a firmware update is required to reflect the revised charging parameters.

Other than the above issue, the battery has been great thus far and hopefully you can of assistance in resolving the OVP issues.

Hi There

 

There is a firmware update that needs to be done for new voltage parameters.

With update, OVP will not kick in that low. 

I'm able to assist remotely if you have the rs232 to usb (see below). if not. we do sell them and can be couriered to you.

Please PM me and we can take it from there.

Good day,

I need your advice or help with my setup.

I bought my SVolt 48V/5kWh battery that is paired with a KODAK OG5.48 inverter at  beginning of this year. It performed really well in the beginning but since there has been no load shedding I did not notice that the performance has deteriorated until we had unplanned outages over the last two months. Now the battery does not even last for 3 hours when running lights and the fridge. When it gets to 89% SOC it switches off completely and when power returns, the inverter does not pick the battery up and i have to manually switch the battery on and reset it for the communication to happen and the battery to charge. Also, while charging and discharging, the battery level appearing on the battery itself and that on the inverter are at different levels. When looking at the BMS record there have been 275 OVP instances so I don't know if the parameters are incorrect but I cannot access them on the BMS i keep getting a message saying "Non-production manufacturer cannot use". 

The battery type on the inverter is set to AGM. I'd appreciate any advice before I find myself buying a new battery again because I am beginning to suspect that this one is fried

270 Over voltage disconnects is seriously problematic. Some information needed. Is there bms comms between inverter and battery? Why is Agm profile selected for Lfp battery? There is diffrent versions of S volt modules there is 15 cell and 16 cell. Hopefully yours is not 15 cell as that would explain the excessive Ovp count. Send a picture of the Svolt rating plate on the side of the module. With so many overvoltage disconnects the chances are good you have swollen cells that will need teplacement.

Thanks for the fast response..

 

So a few things to give background... When I went into this purchase I was totally clueless and relied on a reseller to spec and an electrician to install and setup. As time has went on I am learning and relying on forums such as these. So on the part of AGM being selected for the Lfp battery, that was purely on the installer. ON the part of there being comms, yes there is however I have recently become aware that I may be using the wrong protocol since I am unable to access the Parameter settings on the battery itself. I would however appreciate tips on the correct settings/parameters for the battery and in the event that there are swollen cells that need  replacement, anyone who does this in the Joburg area.

 

The battery is the 15 cell 5.09kWh version. The 16 cell variant was out of stock when I bought.

 

I hope the pics I've attached are enough.

What i can see on the information you supplied the cell balancing is seriously out of wack. The delta( voltage diffrence) is 200mv. The bms has disabled the module or the bms is damaged. I am speculating here as the battery module would need to be opened up and inspected( cell damage, bms damage). The warranty is shot due to constant overvoltage. Where did you purchase the battery from? My brother is situated on the east rand i could ask him to assist if he is available. Pm me should you decide the way forward. This is so unfortunate and unnecessary. You can also contact SVolt tech maybe they will repair or replace under warranty as a sign of good faith. 

@Svolt Tech for your attention above.

When USR (AGM) is selected there is by definition no "comms".  the cable may or may not be the right one, but the inverter will not attempt to use it. It will use the manually specified voltages.

Looking at the settings in your first post (56.4V charge), the inverter is set up for a 16 cell battery.

The combination of the above 2 items is lethal.  Your battery has been systematically overcharged - that would explain its inability to now hold a charge.

Good Day @MrNj

 

Over Voltage for a prolonged period may have caused cell damage or BMS damage as explained above.

Recommended charge voltages for the 48v 5.09kwh battery is

Bulk : 54v

Float : 52.5v

Low Cutoff : 43.5v

 

Your battery would need to be sent in to us for cell and BMS diagnostic. 

OVP - Over Voltage Protection - 270 instances, does void warranty, but i will assist in a resolution, please pm me and i can assist you.

@Svolt Tech thankyou for supporting your customers . I had a 25.6v  2.71kWh s Volt installed also with to high charge voltage of 28.8v Bulk and 28.0v float. It was rectified but after only 32 OVP on no 3 cell . Running for 1 year and 147 cycles . Cells are well balanced now. Will this also void the warrenty .

Technically Yes, but we will overlook it as cells have not been affected. if you ever have an issue with it. Just let me know. And i will assist.

PM me with your whatsapp number and we can assist is you have any issues.

I have 3 of these batteries in parallel with 2 luxpower sna6000wnp inverters,

But I see there is around 60 events of OVP!!

The inverters are set as Pylon,

Why would this be so much in 3 weeks of operation?

Do you have OVP on all 3 batteries? What is your cell delta of each battery? Maybe post cell info from each battery cell imbalance would cause OVP. What is your batteries terminal voltage at 100%Soc.

99% Charge as we speak,

#1: 50.24v DSC message 

#2: 50.24v DSC Message 

#3: 50.54v OVP Message 

Very strange, on the battery they show me 52v @ 100% yet the BMS is logging a OVP!!

@Cyclic with my battery it was only 1 cell that went OVP and it was only the first few days it happend. This cell was out of balance but was balanced after a few cycles . Battery now in operation and cells stay balanced after 185 Cycles.

Before connecting the Svolt battery to the inverter you need to check status of battery. Start up procedure reset the breaker on the side to the "UP"position. Then press the start button and you should get capacity readout on the led's. You should read dc voltage on the terminals. If not you either have a totally flat battery or the bms has disconnected the battery.
