-
Determine battery capacity:
– Battery capacity is often listed in amp-hours (Ah). For example, a common inverter battery may have a capacity of 150 Ah. -
Identify the load:
– Calculate the total power consumption of the devices you will connect. For example, if you connect two devices that consume 100 watts and 200 watts, the total load will be 300 watts. -
Convert power consumption to amps:
– Use the formula: Amps = Watts / Volts. For instance, using a standard 12-volt system:- Total load in amps = 300 watts / 12 volts = 25 amps.
-
Calculate backup time:
– Use the formula: Backup time (hours) = Battery capacity (Ah) / Load in amps.
– Using the previous example: Backup time = 150 Ah / 25 amps = 6 hours. -
Consider efficiency losses:
– Inverters are not 100% efficient. For example, if the inverter has an efficiency of 85%, multiply the calculated backup time by the efficiency factor:- Adjusted backup time = 6 hours × 0.85 ≈ 5.1 hours.
By following these steps, you can arrive at a more accurate estimate of the backup time of your inverter battery, accounting for both the capacity of the battery and the power consumption of your devices.
What Formula Should Be Used to Estimate the Run Time of an Inverter Battery?
