I've build last year a solarsystem with 3,6 kW peak in direction south 0°, 43° on the garage roof with TrinaSolar - panels. 16 pcs LiFePo I bought in China over Alibaba DDP to germany about 1700 EUR in May 2021. The system runs since October 2022 with 3pcs 1000W soyosource on-grid inverters and did safe me until today 1000 kWh grid power.
Because the prices of electric energy rises in europe I want upgrade my system with 12 550Wp Panels on my carport roof and double the capacity of my battery-bank. Therefore I ordered new 20pcs of LiFePo-Cells - described as brand-new grade A - I was quite unsure and didn't want to wait 3 months for delivery again, therefore I searched for a seller, who has EU-Stock. Ami Peng did offer this - the price per cell where 148 EU. I ordered at 21st of september, on 29th all cells where delivered and I made first checks.
Checked inner resistence, voltage and the QR-Codes. I'm very impressed and very satisfied. All cells seem to be from one produktion day; the resistence and voltage with very good tolerance.
The capacity test of the first two cells makes me also very satisfied, both have a capacity of 298 Ah.
I've testet with a EBC-A40L with 40 A charge and discharge current in 3 stages:
- 1st charge to 3,65V, cutoff at 1A current
- 2nd discharge to 2,60V
- 3rd charge as in stage one.
So I can only say, that Im very satisfied and can repeat the resume of OffGridGarage...best value, best seller, extremly fast delivery from poland to germany DDP. ... thanks to Ami Peng and the team of Shenzhen Qishou Technology ... I`ll hope, that other people in the future can also make good expiriences...
Some pictures of the lists of my measurements and photos of the packages....
And some pics of my system from my "power plant" ;-)
