Good for you, no half measures!Caesium wrote: ↑Mon Oct 10, 2022 7:52 am todo list..
yes I ordered more The Pylontechs sold for silly money, more than I paid for them. £900 a pop, so £5400 total potentially once they're all sold, which I'm replacing with £4000 worth of LF280Ks. That takes me from 14.4kWh to around 28kWh and puts a grand back in my pocket. Though some of that is being eaten by balancers and odds-n-sods.
- order 16 LF280K and assorted bits-n-bobs
- build 15S DIY stack to sit parallel to Pylontechs
- sell 3/6 Pylontech to fund this habit
- order 16 more LF280K
- build a second 15S stack in paralle
- sell remaining Pylontechs
- reconfigure both DIY stacks to be 16S
- spend years messing with smart BMS systems
Once I have no Pylontechs left I'm planning to rebuild both stacks to 16S, as I'll have no other 15S to be in parallel with. I'm not envisioning any problems with this. The LXP inverter reckons it can supply charge up to 60v and by that point I'll have far more capacity than I know what to do with (with no panels yet and only 5h of 3.6kW charge capability, I can only refill 18kWh of it a night anyway) so I'll set the charge voltage quite low, probably 54.4v (3.4*16). This should give the cells a nice easy life and not max then out to 100% every night. I can tweak up the voltage marginally if I ever do empty them.
At my end DPD system now recognising the shipping number but not yet in their system. A step forward from previous no know No. £900 a pop is excellent .
