Hi everybody,

Today a new LiFePo4 battery has arrived at me, so I've tryied to install it. It would be pretty easy if I really read the instructions to the controller (it has to be in a manual mode to open output



The battery 12V/12Ah is incredibly light, only 1.9 kg against 3.8 kg Pb. Dimensions is 151x101x98 mm, it's the same as Pb. It would endure for 10 years. The battery has built the balancer and needed protection in. The price in CZ is about USD 80 plus VAT from local distributor: LiFePo4 12V/12Ah PCM



The controller in using is WINCONG SL02A-20A, the price in CZ is about USD 35 plus VAT. (The cheaper SL02A-10A was for long time sold.) It's too from local distributor: WINCONG SL02A-A The dimensions are exactly the same as the budget MPPT controllers, ie. outside dimension is 133x70x25 mm, installation dimensions is 126x50 mm.



If there are in the field of solar panels more pieces, it is important to connected them parallel, so that the resulting voltage of only 18V. I have two panels GWL/Sunny Poly 20 Wp 36 cells (MPPT 18 V). (2x USD 18 + VAT from local)

And here is the final installation:
