Primary Component Sizing
Input the core specs for your $12\text{V}$ system components.
Lithium users: typically $100\text{Ah}$ to $400\text{Ah}$.
Required for AC appliances (e.g., blender, laptop charger).
Total wattage from all rooftop panels.
Charge current from the van's engine/alternator.
Appliance Energy Consumption
Calculations use a $12\text{V}$ system. $\text{Ah}/\text{Day} = (\text{W} \times \text{Hours}) / 12\text{V}$.
