For example, let’s say you plan to power a 100W light bulb for 8 hours, a 200W laptop for 4 hours, and a 500W refrigerator for 2 hours. Your total energy needs would be:
Total Energy Needs (Wh) = (100W x 8h) + (200W x 4h) + (500W x 2h)
Total Energy Needs (Wh) = 800Wh + 800Wh + 1000Wh
Total Energy Needs (Wh) = 2600Wh
Depth of Discharge (DOD) and Battery Capacity
Now that you have a better understanding of your energy needs, it’s time to explore the world of batteries. When choosing a battery for your 2000W inverter, two key factors to consider are depth of discharge (DOD) and battery capacity.
Depth of discharge (DOD) refers to the percentage of a battery’s capacity that can be safely used without damaging the battery. For example, if a battery has a 50% DOD, it means that only 50% of its capacity can be used before it needs to be recharged. Most deep cycle batteries have a DOD of 50% or less, while some high-end batteries may have a DOD of 80% or more.
Battery capacity, on the other hand, refers to the total amount of energy a battery can store. Battery capacity is typically measured in ampere-hours (Ah) or watt-hours (Wh). When choosing a battery for your 2000W inverter, you’ll want to select a battery with a capacity that meets or exceeds your total energy needs.
Calculating Battery Capacity
To calculate the required battery capacity, you can use the following formula:
Required Battery Capacity (Wh) = Total Energy Needs (Wh) / DOD
Using the example above, let’s say you want to choose a battery with a 50% DOD. Your required battery capacity would be:
Required Battery Capacity (Wh) = 2600Wh / 0.5
Required Battery Capacity (Wh) = 5200Wh
