Puredrive Battery

It really depends on your use case. The 1C was important to me, but during winter it's down to 0.5C at least in my case.

From here - https://puredrive-energy.co.uk/firmware-updates/

You need a specific cable for it and a laptop with windows on it. The application is specifically for diagnostic and firmware updates on the batteries. It's not something you should need and really I'd say if any issues get your installer to look at it.

I have 2, no significant issues as such. A fair few alarms but not sure if it's the batteries or the Solis inverter causing them but it all works good apart from that. Alarms are "no battery" and grid related but never caused any real issues to be bothered about. I would buy them again no problem because I can run my electric shower on the single element off them without using the grid.

Are you having any issues with the battery not fully charging sometimes since the update?

I've two of them, ever since the update they haven't charged to 100% without me having to reset them first.

I raised a ticket there. Unfortunately they are notorious for taking an eternity to get back to you....

Make sure they are both compatible, some older Puredrive batteries don't get on with the newer ones afaik. Also remember to fit the RJ45 terminator.

Just got solar installed with solis hybrid inverter recently . Didn't get battery as was very expensive 3.5 k etc? Have seen one now on donedeal for 2.2k for a 5kwH battery. Still in box.

My question is can I install it myself. Is it complicated and is there any risk of messing up current system which working fine?? Also can there be issues with these batteries, obvs big outlay for second hand item.

Thanks

It's beside where you plug in the cat 5 cable on the battery, you should have one on the battery you have where you will plug your new battery into so just plug it into the new battery to terminate it. If you add another (3rd) battery you would move it to the third one to terminate it.

I have 3x 5kWh PureDrive batteries. 1 I got 2nd hand and asked the installer to put install it at the same time as the other 2. They had lots of problems installing any of them to begin with. A more knowlegable installer was then sent out and he got the 2 new ones running but said that he would need a software update to do the 3rd.

That's been several months and the company aren't responding to emails/ calls. Is there anyone someone could recommend to get the 3rd one up and running? It's already attached to the wall so I can't imagine it's a huge job for some who knows what they're doing. At this stage, I'm happy to just pay someone else and get it done.

PureDrive are so slow and frankly lied to me multiple times about sending stuff. I finally did get the cable for the upgrade in the end and asked them to assist over the phone. I was concerned that maybe there was an issue with the battery. They said do it yourself and give us a call if issues.

So I have the cable and was able to get my 5kWh battery updated to the current firmware. The issues I was having stopped.

Where are you based? If you're not far I may be able to help. I'm not an installer though, just another like you that had to muddle through these companies with awful support. :(

The batteries all need to be the same series though. Check the serial numbers, what digit do they each start with?

Does anyone have access to the BMS update tool?

I finally got the update cable sent out but the download is missing from their website.

Hi Jonathan when I click the link it shows the folder empty.

On the cable more than happy to stick it in the post to you when I am done with it.

Ha Long Bay kindly sent me along a cable to test. It worked correctly with my 5kWh battery. I ordered another cable from elsewhere which has now arrived, and will make it up later using the original as a guide. I'll make a post later on the outcome. This will hopefully help others be less reliant on the shambles of PureDrive support.
