Battery Depletion Estimator

STEP 1. Estimate Your Daily Power Usage

(by selecting how long each component will run using the battery each day)

Use the green dropdowns below to select the number of minutes or hours the corresponding component is likely to run each day.

Note: If you do not intend to power a component with the battery, leave it at 0. Also, an inverter is required for 120V items (like microwave, coffee pot, air conditioner) to run on battery.

Total Daily Power Usage : 0 Watts

Component	Wattage of Component (Averages used) Change only if you know the exact wattage of the component.	Select: Mins/Hours	Run Time Per Day	Daily Draw (Watts)
Coffee Pot (Inverter needed)				0
Microwave (Inverter needed)				0
Air Conditioner (Inverter needed)				0
RV Furnace				0
Exhaust Fan(s) (Include total of all fans)				0
Laptop				0
Water Pump				0
TV				0
Interior Lights				0
Exterior Lights				0

Step 2. Select your battery bank size, solar array size, and generator runtime to estimate how long your power will last while dry camping.

Battery Bank Size:

Note: Select your current or desired battery bank size to estimate how many days of power you'll have before depletion, based on your energy usage..

Selected Battery Capacity: 1200

Select Solar Array Size:

Note: Select a system size to see how many days you can extend your battery life using solar power.

Selected Solar Array Size: 200

How long are you willing to run the generator each day?

Generator Contribution: 0
