Hi all,
I project to create a nomade solar panel with USB output. Until then, there is no real problem.
To ensure to be energically independent during my travel, i would implement a battery on this project. But I am not very experienced in using battery.
Up to now, I use a similar product as we can find in specialized store wich I identified as un buck/boost system (pictures in attachment).
Is somebody can give me advices to implement battery on my system ?
The specifications on the solar panel are : Voc = 10,5V / Isc = 120mA // V=7,2V and I=100mA at the optimal point.
The battery is typically a 2000mAh single cell.
Moreover, how can I ensure my solar panel work at his MPP (max power point)? It is use for real PV grid (high power) but is it necessary for this kind of use ? The MMPT are expensive and I have not find cheap for a nomadic use.
Thank all for your help, your advices and to share you know relative to this project
