2nd hand batteries

    I'm looking to supplement my 2.4kW PylonTech with another battery (5kW inverter) and was just wondering about a 2nd hand battery with SOH >95%.

    If you can find them you should have no problems

    Save me money website sent me email recently that they had 3k of pylontech refurbished in stock with 20% off retail price if you want to try them. Never used them myself and holding out for new pylon stock due in next week. Would consider a used battery if less than a year old but would need to be decent savings to warrant it.

    Keep an eye on the DIY battery thread. As more people dip their toes into that, they'll be selling their old batteries.


    I sold 2 pylontech 2.4s to a boardsie a few months back.

    I would not mind the age of the battery if it was not abused. 1 year old can look worse than 3 year old. For pylontech batteries it is easy enough to connect to them and check what the state the cell are in and general SOH.



  • Registered Users, Registered Users 2 Posts: 2,021 ✭✭✭jkforde


    good idea and at least now we have a dedicated thread for 2nd hand batteries if people want to sell to us techphobes 😀

    EV breakers yards are springing up,but you need to know what your buying and go safely.



  • Registered Users, Registered Users 2 Posts: 547 ✭✭✭Blue4u


    It also a significant piece of work to convert a battery from EV to solar



  • Registered Users, Registered Users 2 Posts: 1,460 ✭✭✭reboot


    Quite right,and with all lithium,dangerous. However in a small scale simple setup like mine, a possible alternative to lead acid. Thanks.

    Folks

    Just spotted these on Donedeal and thought of this thread. Price is very very good if they check out.

    €520 for 18 month old Pylontechs. Can't see these hanging around


    Pylon 2.4kWh Battery Hybrid Inverter Solar PV for sale in Limerick for €520 on DoneDeal



  • Registered Users, Registered Users 2 Posts: 12,623 ✭✭✭✭DrPhilG


    That seller is either not telling something, or is a dimwit.


    I sold mine at just over a year old for a good bit more, and considering that they're in such short supply currently they could easily get €750-800.

  • Registered Users, Registered Users 2 Posts: 325 ✭✭E30M3


    I don't think they are a dimwit as they seem to be involved in Solar Supply/Installations going by the other ads they have. Maybe they don't deal in Pylontech's and just want to move them on?



  • Registered Users, Registered Users 2 Posts: 3,245 ✭✭✭irishchris


    Also if anyone is looking for a like new Solis 3.6kw hybrid I have one for sale. I bought it in April of this year. Paid 1460 for it but willing to let it go for 300 euro off that.

    Said I'd put it to here first before adverts.ie in case anyone was going changing to a battery charging hybrid



  • Registered Users, Registered Users 2 Posts: 1,460 ✭✭✭reboot


    I take the 3.7 v lipo cells from the modules and make up packs of differing voltages for various workshop projects. Charging and battery balancing is via Turnigy charger, fed by PV solar project.

    No mains involved and around €300 spent in total. Just thought time to move on from lead acids and hernias!



  • Registered Users, Registered Users 2 Posts: 2,021 ✭✭✭jkforde


    I'm interested so what Q's should I ask

    1. Model

    2. SOH

    3. Warranty

    4. Cables for stacking

    5. Live video showing the gear? 😂

    If I have a Solis Hybrid INverter - paired with a Dyness battery (4.8Kw) and I want expand... what are my expansion options?

    Do i have to get a simlar battery from Dyness? Or is any compatible battery with the inverter OK? Does the battery have to match the same exact size as well?



  • Registered Users, Registered Users 2 Posts: 793 ✭✭✭reklamos


    It is like buying a car they all ads say they are clean inside out and fly through NCT. But you only know if that is true if you look under the bonnets, kick some tires and take it for a spin :)

    You can get a lot of info out of them just by connecting rs232 cable and running some commands. It will show SOH, cycles, each cell level, errors etc.

    You will need same battery from same manufacture as they would need to be connected to each other and need to speak in the same language. Idealy you should not mix different sizes.

    If people are stuck for sourcing new pylontech batteries as I was, I know of mayo supplier that had just got pallet in this week of them. If anyone wants his details drop me a pm



  • Registered Users, Registered Users 2 Posts: 1,875 ✭✭✭garo


    In case anyone is looking, I have a Aug 2019 installed Pylontech US2000 for sale. Comes with power cables to connect to inverter - not to connect to another battery - and with a steel cabinet and earthing cable.

    Batteries have been kept in a garage and have an aggressive setting to lower charge amps to 10A at 18C so SOH should be very good. Approximately 800 cycles and were discharged to 16% max. Currently stored at 50% SOC. Looking for 700. Based in Dublin.



  • Registered Users, Registered Users 2 Posts: 1,875 ✭✭✭garo


    Bump. Gonna put this up on adverts this weekend. PM me for details.



  • Registered Users, Registered Users 2 Posts: 12,623 ✭✭✭✭DrPhilG




  • Registered Users, Registered Users 2 Posts: 114 ✭✭daithihalton


    @garo Did you sell the battery or is it still available



  • Registered Users, Registered Users 2 Posts: 1,875 ✭✭✭garo


    Sorry it's gone to a boardsie.



  • Registered Users, Registered Users 2 Posts: 114 ✭✭daithihalton


    No problem, thanks for getting back to me



  • Registered Users, Registered Users 2 Posts: 11 shanemc30

    Fella on the Facebook Irish solar group selling 3 x Pylontech us3000 currently if its any use to anyone.



  • Registered Users, Registered Users 2 Posts: 12,623 ✭✭✭✭DrPhilG


    2 x Pylontech us2000 on there now too.



  • Registered Users, Registered Users 2 Posts: 1,765 ✭✭✭ds20prefecture


    damn are they going that fast? Would love another 1 or 2 Pylontechs - have a 3U cabinet



  • Registered Users, Registered Users 2 Posts: 12,623 ✭✭✭✭DrPhilG


    Anyone need a Pylontech cabinet? One going cheap here. Think it holds 3 maybe?



  • Registered Users, Registered Users 2 Posts: 475 ✭✭jspuds


    Pylontech have sent me 3 new US2000 batteries so if anybody is interested in the old batteries please make me an offer via PM.

    They are reporting 100% SOH but are showing signs of degradation, not sure if they can be resuscitated fully might make an interesting project for somebody more skilled than me.



  • Registered Users, Registered Users 2 Posts: 11 shanemc30


    Still looking for pylontech batteries if anyone has any available

    Chauffe, Marcel, chauffe!


    I got jspuds' Pylontechs. Some very bloated packs in them 😁

    It's LiFePO4, so not dangerous at all.

    The Pylontech US2000 have 3 internal battery packs in a 5S configuration each, this evening I have taken 3 out and combined them into a 48V nominal pack. It charges and discharges fine. Haven't done any capacity test yet but might see what range I get on my eBike with this 😂 or use it with my 48V inverter and a granny cable as an eJerryCan™ for one of my EVs to alleviate range anxiety 😎

    @shanemc30 - not sure if you are looking for new or top condition used Pylontech batteries or if you would be interested in one of mine. If so, feel free to send me a PM. I'm in Lucan



  • Registered Users, Registered Users 2 Posts: 66,132 ✭✭✭✭unkel
    Chauffe, Marcel, chauffe!


    For the craic. I charged the opportunity pack above up for a bit, then connected a cheap Chinese 48V inverter. Connected a heavy load (1000W heatgun) to it and I've been running that since. Well over an hour now and running perfectly. Checked with a mate of mine who is an expert in off grid and he said bloated cells do not necessarily mean any reduced capacity at all. Looks like he is right.
