A simple rule of thumb says you'll want around 400–500 Ah at 48 V (≈ 20–24 kWh) to deliver one full hour of continuous output from a 5000 watt inverter —then scale up from there based on how long you need the power to flow. . Pairing a right size capacity battery for an inverter can be a bit confusing for most the beginners So I have made it easy for you, use the calculator below to calculate the battery size for 200 watt, 300 watt, 500 watt, 1000 watt, 2000 watt, 3000 watt, 5000-watt inverter Failed to calculate field. The battery capacity, the inverter voltage input and how long you need to use the inverter are important. Large inverters are used as emergency power backup, so determine how many hours the system will run. You'll learn how to. . To power a 5000-watt inverter, you typically need four to six 12V batteries rated at 100Ah each, depending on the load and duration of use. Always consider the depth of discharge and battery. .
