To determine the size of the inverter needed to power an air conditioner with a cooling input power of 1500W, you need to consider the power requirements and efficiency of the inverter. Here's the calculation:
Account for Inverter Efficiency: Inverters have some energy loss during the conversion process, so you need to take their efficiency into account. Let's assume an inverter efficiency of 90% for this example.
Calculate Power Requirement: The cooling input power of the air conditioner is 1500W.
Determine Inverter Output Power: To calculate the inverter's output power, divide the air conditioner's power requirement by the inverter efficiency: 1500W รท 0.9 = 1666.67W (approximately).
Consider Battery Voltage: You have a 24V battery bank, so the inverter needs to be compatible with that voltage.
Based on these calculations, you would need an inverter that can handle an output power of at least 1666.67W and operates with a 24V battery bank. In practice, it is advisable to choose an inverter with a slightly higher power rating to allow for additional loads and to ensure the inverter can handle peak power demands. A 2000W inverter or higher would be suitable in this case.
Keep in mind that other factors, such as the starting surge of the air conditioner and the inverter's surge capacity, should also be considered. It's recommended to consult with a professional or refer to the manufacturer's specifications to ensure you choose the right inverter for your specific setup.
