Start by assessing your daily power consumption which helps to calculate battery size for inverter. Make a list of all the appliances and devices you want to run on your inverter system. For each item, note the power rating (in watts) and how long you use it each day. Example: LED Light Bulb: 10 watts, used for 5 hours/day
This depends on the battery’s amp-hours and your devices’ power draw. Divide the battery capacity by the total amps to estimate the backup time. For instance, a 150Ah battery for a 600-watt load can last about 6 hours. By accurately estimating your power and runtime needs, you can pick the best inverter battery size for your backup power.
For a 2000W inverter, a 200Ah battery is a good choice. This battery can give you 2-3 hours of power for important home devices. If you want more runtime, go for a 300Ah battery, which could last up to 4-5 hours with a 2000W inverter. With a 3000W inverter, you’ll need two 12V, 200Ah batteries in parallel.
The capacity of an inverter battery, measured in ampere-hours (Ah), determines how much power it can store and supply over time. A higher Ah rating means the battery can provide backup power for a longer duration before requiring a recharge. The basic formula for calculating battery capacity is:
A 1000W inverter needs a bigger battery than a 600W inverter because it uses more power. A 1500W inverter requires an even bigger battery for the same backup time. Knowing what size inverter you need for your refrigerator helps pick the right battery capacity. Think about the appliance’s power use and how long you want backup power.
The input voltage of the inverter should match the battery voltage. (For example 12v battery for 12v inverter, 24v battery for 24v inverter and 48v battery for 48v inverter Summary What Will An Inverter Run & For How Long?
