Puredrive Battery

Is 20% soc discharge limit what everyone is using or could this be lowered?

Can you add any battery to work with a Puredrive battery and a Solis Hybrid inverter or do you need to use the Puredrive? I am thinking of adding a battery soon after a recent install and could do with a little more storage for next winter as I found the 5kw Puredrive just runs out a couple of hours too early in the mornings before the panels kick in.

Can you pm me on that? I would be interested.

My installer wanted €2500 for another 5kw when I asked about a month ago. I don't see any for sale second hand anywhere. I picked up the one mentioned a few posts back and the 10kw I have now is sufficient for my needs.

Have found the Puredrive batteries pricey also when looking to add a second hence why I have ordered direct with a manufacturer in China.

Looked at DIY route also but the few issues put me off this option.

Actually contacted a few manufacturers pricing different batteries from rack mount to the powerwall type.

Ended up ordering 10x5kWh rack mount (min. quantity required to make it viable) although won't be using these and have a few reserved for boardsie's and a friend.

Going by the €2500 quoted above for adding a second puredrive then these will be saving €900+, the piss poor $ exchange rate lately doesn't help. DIY still offers better value but it isn't for everybody.

These batteries will be added to the Solis inverter setup in the coming month or so, so should be plug and play although I have been sent the settings for adding them for now. Being the guinea pig here but they have been used in various projects in the UK, USA, Australia etc. Hope to have them landed with the next two months all being well.

These will be plug and play, the same as the Puredrive without the expense.

I intend removing the puredrive and replacing with 2-3 of these.

Like everything these days there have been delays (partly due to me), has just shipped so probably another month before I see them.

Hi aleesi.

These are not a diy battery but a rack mount battery similar to the pylontech and dyness e.g with their own inbuilt bms.. I'll be taking the puredrive out (a good battery by the way) and replacing this with 2 or 3 of the rack mount batteries.

All being well these are due into Dublin this weekend and I would therefore hope to have them hooked up next week. Should have had them several weeks ago but there have been delays for various reasons which I figured would be the case anyway as I am well used to things being delayed through work, especially coming from the far east.

With the evening getting shorter it is a good time to be receiving them as the next few weeks with see us shifting to charging on night rate anyway.

waiting on the final tally on collection as I've had a couple of rates for import duty so will have a concrete price then

I got nearly 20kWh of prime CALB cells for not much more than that. Just sayin...

I dont think you will get that now + BMS with current Euro exchange rate

Probably not, but to give an indication of how expensive pre-made batteries are. While most of them use inferior battery cells.

Currently have it but will be selling once I have the other batteries in and tested.

New batteries due in Dublin Port this weekend so I should have them next week.

So... It started with No Coms and the Solis inverter would restore the link and alarm would clear..once a day , then it started to escalate to NO BATTERY alarms 2-3 times a day .. then it went to BATTERY NAME FAIL and the Inverter would go into non operational mode with the battery selected. Most of the time the LED on the front of the battery was green then it started to go red. Puredrive were really indifferent about the problem on the phone ..offered no help no apologies ,no we will send another battery etc just "yes we know" .

Installer is putting in a Dyness to see how that goes .
