Inverter Efficiency: Inverter efficiencies typically range from 85% to 95%. For the purposes of this calculation, let's assume that the inverter is 90% efficient. This means that in order to provide 3000W of AC output, the battery needs to provide approximately 3000W / 0.9 = 3333W of DC input.
Battery Voltage: Assume we are using a 12V lithium battery. To calculate the required Amp Hours (Ah), we use the formula: Required Amp Hours = Input Power Watts / Battery Voltage. For a 1 hour runtime, Amp Hours Required = 3333W / 12V ≈ 278Ah.
Number of Batteries: If we choose a single 12V Li-Ion battery with a capacity of 100Ah, then the number of batteries we need is: Required Ampere-Hours / Ampere-Hours of a Single Battery = 278Ah / 100Ah ≈ 2.78. This means that we will need at least 3 100Ah 12V Li-Ion batteries in parallel for 1 hour of full load operation.
Practical Configurations: In practical applications, more batteries may be required to ensure system reliability and redundancy. For example, using three 100Ah batteries in parallel will provide a total capacity of 300Ah, which is sufficient for approximately one hour of use at full load.
Therefore, based on the above calculations, a minimum of three 100Ah 12V lithium batteries in parallel would be required to power the 3000W inverter for one hour at full load. Actual configurations may require more batteries depending on the desired runtime and redundancy requirements of the system.
