We are trying to implement a Point of Sale system for retail sales at remote location. There is no A/C power to speak of, but a generator that charges a bank of deep charge, gel 12volt batteries. We want to run a couple of notebooks or laptops for sales directly of the bank of batteries rather than invert the D/C to A/C. This loses so much in the invertion process that it is inefficient.
I know you can run laptops off external powersources, but how can I regulate the power off the bank of deep cells to match these laptops?
Thanks for all your help,
Stephan
