How to determine the size of a power backup inverter?

To determine the size of the Inverter which perfectly suits your power backup requirement, here is the step by step calculations: Step 1: Find out your total power load that will be consume by your selected appliances at the time of power outage. In previous section “Load Calculator” we have covered how to calculate your total load.

How do I find my home inverter's power needs?

Use Livguard's electricity load calculator to find your home inverter's power needs. Easily compute appliance loads for the right inverter size. Optimize energy use now!

How does the inverter load calculator work?

The calculator uses the inverter load calculation formula to sum up the total power demand in watts or kilowatts. Based on the total load, the tool recommends an inverter size from the inverter size chart calculator or the best inverter size chart.

How to calculate inverter size?

The following steps outline how to calculate the Inverter Size. First, determine the total power consumption (Watt) of all the devices that will be connected to the inverter. Next, determine the power factor of the devices. This is usually provided in the device’s specifications.

How do I calculate power back time of my inverter battery system?

To determine the power back time of your Inverter Battery System during the power outage with your running appliances, lets do the calculations. Here is the formula: Battery Backup Time (Hours) = Battery capacity (Ah Rating)*Input Voltage (12 Voltage) / Total Loads (Watts)

How do you calculate inverter capacity?

The capacity of an inverter is typically measured in Volt-Amperes (VA) and must match or exceed the total load requirements of all connected devices. The formula to calculate the required inverter capacity is as follows: \ [ \text {Inverter Capacity (VA)} = \text {Total Load Wattage (W)} \times 1.25 \]
