A 100ah battery can run a 1000 watt inverter at full power for an hour, but if the inverter has a 50% discharge rate, the battery size has to be doubled to 200ah to run for an hour.
To run a 1000 watt inverter for an hour on a 12V lead acid battery, you would need a battery with a capacity of 200 ampere-hours (Ah). By the time the battery drops to 50% charge, the inverter would have run for the prescribed period. Our top pick, the Renogy 12V AGM 200, is a suitable battery for this purpose. This formula is applicable regardless of the inverter or battery size.
To avoid complications, the battery size for a 1000 watt inverter should be double what is needed. If the inverter needs to carry a full load for 2 hours, a 400ah lead acid battery is sufficient. Even when the battery level drops to the halfway mark, the inverter can still use around 166 amps, which is more than enough. Another option is to use a lithium battery bank.
A 1000 watt inverter draws 83.3 amps when running a full load for one hour. You need a battery with a capacity of at least 83.3 amp-hours, but it's recommended to use a 100 amp-hour battery to account for inverter inefficiency. However, keep in mind that batteries discharge faster when more amps are drawn, so the battery may only last for an hour under these conditions.
You would need around 24v 150Ah Lithium or 24v 300Ah Lead-acid Battery to run a 3000-watt inverter for 1 hour at its full capacity Here's a battery size chart for any size inverter with 1 hour of load runtime Note! The input voltage of the inverter should match the battery voltage.
With a 1000 watt inverter, you can run an average laptop for approximately 4 to 5 hours (200 watts x 4-5 hours = 800-1000 watts). A 50 inch TV draws 3.7 amps an hour, which is equivalent to 444 watts.
