Hello. Could you please show me the schematics of this device? I'm not sure whether i could do the job without pre-examination your schematic. It could be PDF file or simple graphic file (JPG, GIF et.c.) And, of course, please name the type of the battery you are using - Li-Ion, Pb or something different. Thank you.

I think that with my experience in big power system I can help you with this task, and y I would provide you more than you need. For example, I work every day running simulations with the whole electric system in Argentina, networks of 500kV, 220kV or 132 kV. I model new generators, branches and busbars, and I make diferents simulations. So for all these reasons, I thinnk that I help you with this project. I would like to know more about the projetc, you have to desing only the equipment? would you like to get simulations about the project? what kind of report do you need? I thinh this work could take me two or three days. It would be a pleasure to me to contact you and work together Regards Gonzalo
