Puredrive Battery

Hi Folks

Still not sorted here. I’m waiting for the installer to come back and upgrade the firmware on the batteries. It requires a direct connection strange said it can’t be done remotely.

It wasn’t working at all initially but change to to an LG Chem setup, so there is some charge and discharge, but I’m certainly not getting a 10 kW range from the set up.

Pure drive have acknowledged there is an issue. Hopefully it gets sorted soon in particular, as a unit rate are due to go up!

If not, I’ll be looking to swap at pure drives as I don’t want to be messing around with these for the winter.

Battery doesn’t discharge once the solar drops, it’s that simple. It’s an an acknowledged problem by purdrive. New firmware being installed on Friday which they are confident will solve the issue

Thanks Murt I'll give it a go this evening and report

Have you looked at what the Over discharge SOC is set to? Just on the off chance it's set to 80%.

went back over your instructions again @Murt2 . This time the battery had already stopped discharging at 80%. Did the reset and checked setting v @ 44.0 and over discharge is at 20%

at this point I just don’t know, very frustrating to have all this kit and it not working correctly.

going to see if puredrive will send me the firmware kit. I have a Gaa pitch to stand beside in the morning for 2 hours.

I’m not going to lie to you @Murt2 I’m 4 Guinness in, this will be checked tomorrow 😉

Could this be it!

it’s always set to self use mode, however in backup it was SOC 80%

so I have changed that to 20%.

( I’m assuming I could also just disable backup).

fingers crossed this does it! Will be checking at 21:00 and will update.

thank you everyone for the constant supply of tips!

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.

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.

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.

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?

If you have Solis Cloud app press your plant name then press device then press inverter and then press battery more>

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.

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.

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?

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.
