Wanted to start a thread for a place for info for whomever has the puredrive DC batteries installed with their system.
Yes this setting had to be changed as well on my end. Luckily my installer did it when adding my backup supply
Success!!
thank you for all the help, everyone!
with the ways things are on energy cost currently, ensuring you have as much independence as possible is paramount. Thanks again.
Hi All, seeing some issues with sudden voltage & SOC drops on my PureDrive II 5kWh battery. This is happening when around 25-30% SOC and a high load 50A is put on. It's suddenly dropping to 10% and then the Solis is kicking force charge.
I'm trying to figure out how to open a ticket with PureDrive. Where can I see the battery S/N? Is it in the Solis Cloud app anywhere? or do I need to see it on the actual battery.
Here is a link to where you can log a call with Puredrive. I believe the serial number is on the sticker on the left side of the unit.
Doubt there is anything wrong if you didn't charge the battery in a few days.
SOC drift is what you are seeing - if you're charging this nightly then for sure log a call with them.
I never said that I didn't charge it. It generally gets charged to 100% each day. It had charged to 100% the day before this issue occured and there was sufficient charge and generation expected that day so I didn't charge overnight.
I opened a ticket with them earlier. Will see what they say.
Sudden drop to 10% happened again this evening and now the battery is flashing. What does that mean? Green light blinking
EDIT: nevermind, found on page 1
Puredrive said that they believe my battery needs the firmware upgrade. They're going to send the kit to me and said that I can do it and they'll provide support on that.
Has anyone else done it themselves?
Hi there @hick I too am having to use the LG Chem setting. When you say it’s not perfect, what flaws have you noticed? Also, do you get the firmware update and did it help at all?
Hi all looking for some advice please. I have 2 x Puredrive 5KW DC batteries and have noticed in the last week or so that they seem to be out of balance, when my Solis inverter says the batteries are at 20% only one of them is flashing green making me think the other is still over 30% as its LED is still solid. when I look at the charge and discharge SOC graph they appear to charge as normal up to 91/92% then jump to 100% and when they discharge they drop steadily from 100% to 31/32% and then jump to 21/22%
So my question is.. is there an easy way to make the batteries balance themselves or is there something else at play here.
Where can I look at the charge & discharge graph for my battery?
If you have Solis Cloud app press your plant name then press device then press inverter and then press battery more>
As Con747 said
You can see overnight where mine jumped from 91% to 100% and this evening when it gets down to 31% it will jump down to 21%
Thats is exactly the type of behavior in a phone battery when the battery is knackered. It jumps big jumps up and down in % charge as it charges or depletes. These jumps get bigger over a few months and then it just doent last long at all after charging.
Does anyone know how to turn off/power down a puredrive battery?
There is a button on the top, lift the cover after unscrewing the 2 small twist screws on each side and it's on the right. You can turn it off by feel if you put your finger in the right hand side under the cover. The inverter might stay off until the PV kicks back in though in the morning because the battery powers it when no PV.
I saw some mentions on the Solis facebook group that there was a firmware update just about a week or two ago to handle poor cold weather performance on these batteries. I'm still waiting them to send me the kit to upgrade so will be interesting to see what if any improvements are seen then. I guess it will be the new year at this rate before I get the kit. :(
I've been waiting for this kit for nearly 3 months now! Don't hold your breath...
I just want to know the process to balance the batteries. It can't be that hard surely as they are designed to be easy to add another battery to in the future, there has to be a simple process. I suspect it's going to be something like turn everything off, disconnect batteries from inverter, turn batteries back on and leave for a while to balance each other out but there just seems to be no information around on the process.
The way I would do it is to connect only one battery at a time, charge each from the grid to 100% and when both are 100% wire them back both together.
Ah that's ridiculous. I'll be giving them a call in the new year.
I'm sick of getting the run around by companies, dragging stuff out endlessly.
Why didn't that occur to me 🙈 LOL.
Ok so this morning I disconnected the batteries and charged them one at a time, one displayed 98% on the inverter the other 93% I'm not sure this is enough to account for the jump from 88% to 100% when charging overnight or the drop at the end of yesterday from 33% to 21%, a difference of 12% at each end of the cycle but they are both starting from 100% this morning so will see what happens this evening (the temptation to plug a car in is strong though)
I think what might happen here is that the good battery (98%) is being dragged down to the capacity of the 93% one as that's how they usually work.
You could try cycling each of the batteries individually a few times, see if that fixes the SOC values.
Yep that's the plan I'll see how they do today and if there is still a drop off around 30% I'll run each battery on its own for a few cycles before linking them again and then I'll start chasing installer and Puredrive in the new year if things haven't resolved.
Quick update: So I have cycled each battery on it's own 3 times and then connected them back together at 100% and cycled again with no change. I'm still seeing a drop at the end of discharging, and a jump at the end of charging. I managed to catch a video of the inverter screen each time and have now opened a ticket with Puredrive but not expecting to hear anything for a few days given the time of year.
State of health dropped to 99% during the nightly charge last night. Battery about 7 months in at this point. How are others fairing on the SOH?
Pretty sure mine went to 99% a lot sooner than that and I never charged it from the grid when I had it.
Puredrive explanation: SOC/SOH values are really hard, don't worry about it etc...
Mine 99% also @ hick are you sorted
Would people be charging roughly the same amps/time etc..?
I have mine worked out to spread the charge during my cheap period of 3 hours. If you have a longer cheap period then you could lower the rate. You don't need discharge rate set.
