A 2000-watt inverter can run a variety of appliances including large ones with huge power requirements like an electric oven or a space heater. However, the battery size will determine what appliances you can run and how long you can run them for.
When using a 2000-watt inverter, it’s important to consider the wattage of the appliance you are using and the battery size required to provide enough power. In this article, we provide some general guidelines on the battery size required for a 2000-watt inverter.
What Can You Run off a 2000-watt Inverter?
A 2000-watt inverter with 6000-watt surge watts is a powerful inverter that can run high-wattage appliances. This includes an 1800-watt space heater, 1500-watt hair dryer, and some electric ovens for a period of time. We cover this later.
A 2000-watt inverter can also run some other smaller household appliances like blenders, coffee makers, and microwaves simultaneously. You can also run power tools like drills and saws and most electronics will run on this inverter.
Note that the battery’s capacity and type may vary based on the inverter’s efficiency, the number of devices connected, and the length of time you want to run them. It’s also important to note that the actual power consumption of devices may vary depending on their make and model. So let’s look at the size of battery you’ll need for this inverter
What Size Battery for a 2000-Watt Inverter?
To ensure the inverter provides enough power, it’s important to choose a battery with sufficient capacity. To size the battery we’ll first calculate the number of amps required and estimate the battery capacity in amp-hours
How Many Amps Does a 2000-watt Inverter Draw?
To find the size of the battery, you divide the watts by the voltage.
For a 12v system, you’ll need
2000/12 = 166.67 Amps
A 12-volt system should have a battery that can safely provide up to 166.67 amps of current.
For a 24v Inverter, you’ll need
2000/24 = 83.33 Amps
A 24-volt system should have a battery capable of providing up to 83.33 amps of current per hour.
And a 48V Inverter
2000/48= 41.67 Amps
For a 48v Inverter, you’ll need around 41 amps.
I would recommend you use a 24v system or if possible go for a 48v one as the amp draw is more manageable. A low voltage system may not operate at peak efficiency and with over 167 amps draw you will need quite a big battery and it will cause huge losses in power due to heat.
What Battery Capacity Will you Need for a 2000-watt Inverter?
Deep cycle Batteries are recommended to be discharged at 20% of their capacity each hour. If we were to go five times of our 83 amps you will need a 400Ah 24v battery or two 200Ah lithium batteries wired in series. This is enough to last five hours with the inverter.
If you using a 48v system a 200Ah 48v battery will last just as long.
You may not need to run your appliance for this long period of time. For example, you just need to use a hair dryer for 30 minutes. This will require a different capacity.
|Length in time||Watts Requirements||Battery (24v)|
In conclusion, a 2000-watt inverter is a versatile power source that can be used to run a variety of devices and appliances. When selecting a battery for a 2000-watt inverter, it’s important to consider the power requirements of the devices you want to use and the length of time you want to run them. We recommend a LiFePO4 24-volt deep cycle battery with a capacity of at least 200Ah for this inverter. However, the specific battery size required may vary based on the inverter’s efficiency, the number of devices connected, and the length of time you want to use them.
