Ron, You likely need a load pattern to properly size a system. The load pattern will also show fuel usage. There are real saving from running the generator fewer hours per day and then running it at closer to full when charging the batteries.
Good luck!

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.
