[RE-wrenches] real world example - fuel saving with battery bank

[Ron Young]

Hi Wrenches, 
I'm putting together a proposal for a national company that has a few remote installations. They are looking for options for saving generator run-time using an inverter-charger/battery combo with the existing gensets. Does anyone have any real world examples of realized fuel savings in this type of scenario? They run generators 24/7 and a lot of the dusk to dawn energy requirement is well below the daytime needs. Appreciate any ideas or examples.
