Regardless of the size, the calculation steps are always the same. Using this calculation, a 24V inverter with a 100ah battery and 93% efficiency can run a 500W load for 2.3 hours. You have a 24V inverter with a 150ah deep cycle battery. The inverter is 93% efficient. You want to run a 700 watt load, so how long can the inverter run this?
Here''s why it matters: Let’s say you have a 5kW solar system and you’re using an inverter with 92% efficiency. That means you’re only getting 4.6kW of usable power. Compare that with an inverter that has 97% efficiency—you’d be getting 4.85kW. Over a year, that difference becomes hundreds of kilowatt-hours.
To calculate the usage time of an inverter, multiply the battery capacity by 12 (to convert Ah to Wh assuming a 12V battery), then multiply by the inverter efficiency, and finally divide by the load power. What is Inverter Usage Time? Inverter usage time refers to the duration an inverter can supply power to a load before the battery is depleted.
Most inverters are 24V, so make sure your batteries have matching voltage. If you want to run a solar panel system, use either 24V panels or connect 12V panels in a series to increase the voltage. Make sure that all the components are compatible with each other before connecting any appliance.
