How big a battery should a 5KW inverter use

4 FAQs about [How big a battery should a 5KW inverter use]

How many batteries do you need for a 5000W inverter?

Since partial batteries are not possible, you would need at least 3 batteries of 48V each to supply a 5000W inverter running at 110V. For a 240V system, the inverter draws 20.83 amps. Using the same formula, with a 20A discharge current: Number of batteries = 20.83 amps / 20 amps ≈ 1.04 batteries

How many watts can a 5000 watt inverter run?

While the inverter can provide up to 5000 watts continuously, the actual power output at any given time will depend on the load connected to the inverter and the energy available from the input source, such as solar panels or batteries. This is why we recommend listing all the loads that a 5000w inverter will run.

How many batteries do you need for a 240V inverter?

For a 240V system, the inverter draws 20.83 amps. Using the same formula, with a 20A discharge current: Number of batteries = 20.83 amps / 20 amps ≈ 1.04 batteries This means you would need 2 batteries to safely supply a 5000W inverter running at 240V.

How to choose an inverter battery?

The most common choices for inverter batteries are 12V, 24V and 48V. When choosing the battery size, always go for higher voltage. We recommend a 48V battery because it is efficient, cheap, and safe. On the other hand, capacity is the amount of electric charge a battery can store and deliver over a certain period.
