Going to purchase an inverter but unsure about the wattage that you should opt for? Believe me, you are not alone in this struggle because when it comes to electronics everyone gets confused. Watts, volts, amps, etc. terms make you feel like an outsider. But all these things are pretty easy to understand and with a better understanding, you will be able to get the inverter easily. Today along with all the terms you will learn about how many amps does a 2000 watt inverter draw? Do you know how many amps does a 200 watt inverter draws?

**What are Amps in Inverters?**

The electric current running through the wires at the moment is measured in amps or amperes. This unit does not count as amps per hour or amps per day. The unit for an amp is 1 Coulomb per second. It is important to know the amps of a device for it determines which wire is best suited for it. Current flowing through wires heat them up, but a particular wire will resist the heat due to its competency and design.

**How Many Amps Does A 2000 Watt Inverter Draw?**

These power inverters have a voltage range between 12V and 120V. The maximum amps (current) drawn by a 2000 watts inverter depends on the following factors:

- Its conversion efficiency
- Voltage rating of the battery bank

A 2000-watt power inverter running on a battery bank of 12V would draw around 240 amps and with a 24V battery bank 120 amps could be drawn. However, a battery bank with a 48V would not exceed 60 amps. You can use the following formula to calculate the number of amps drawn by your 2000 Watts inverter.

**Maximum current drawn (Amps) = (2000 watts / efficiency of inverter in %) / the lowest battery voltage (V)**

Here, the lowest battery voltage (before cut off) is 10 volts for 12V, 20 volts for 24V, and 40 volts for 48V battery bank.

Your inverter of 2000 watts and 12V with a 90% efficiency claimed by the manufacturer the amps drawn would be.

Maximum current drawn (Amps) = (2000 watts / efficiency of inverter in %) / the lowest battery voltage (V)

= (2000 watts / 90%) / 10 V

= (2000 watts/0.9) / 10 V

= 2222 watts / 10 V

= 222.2 amps

It would be 111.1 for a 24 battery bank with 20 volts lowest voltage. After this, let’s also try to understand how many amps does a 3000 watt inverter draw.

3000 watts / 120 volts / 0.85 = 29.41, rounding to the nearest it gets 29.4 amps. This has explained how many amps does a 3000 watt inverter draw.

**How Many Amps Does A 200 Watt Inverter Draw?**

A 200 watts inverter is a low-power inverter. It is portable and supplies grid-live power to small appliances in your car or an RV. However, their load capacity is limited, and they are prone to get damaged easily. A 200 watts power surge is 400 watts and its continuous power draw does not exceed 200W. Towards the AC (alternating current) side a maximum current of around 1.8 amps is provided by the appliances. These are connected on the 110V side at the peak power.

**1. Basic terms**

**Watts (W):** It is the unit to measure how much power is used and supplied by a device once it is turned on. It is mentioned as watts and not as watts per hour or watts per day because Joule per second is the defining unit for a watt.

**Watt-hours (watt-hour):** It is the measurement of the power used for an hour. It is also mentioned as a kilowatt-hour (kilowatt-hour) for 1000 watts for 1 hour or 1 watt for 1000 hours. A light using 100 watts for 9 hours will say 900 watts-hour for the light.

**Amp-Hours (AH):** This is the unit for the battery capacity. It determines the time period for which the inverter can run. Amps-hours is calculated by multiplying amps and time.

**2. Facts to Determine While Using the Appliances With the Inverter**

Before determining how many amps does a 2000 watt inverter draw, you need to consider the following things.

- Types of appliances and their running time
- Other constant loads, like refrigerators, pumps, lights, etc.
- Age of the battery/batteries
- Source of charge for the inverter (alternator, solar, or generator)

**3. Amps Drawn By Inverter in Idle Mode**

A good inverter has a very low idle or no-load power draw. This ranges between 0.3 and 0.6 amps. It means the batteries are not unnecessarily used if your inverter is in idle mode. However, some inverters may draw more than 40 amps in an hour which is not good for the batteries. Therefore, it is advised to switch off the inverters when not in use.

**4. Applications of a 200 Watt Inverter**

This low-power inverter provides 200 watts of continuous power. They are sufficient to run appliances with a low Alternative Current. Devices like cell phones, DVD players, electric toothbrushes, fans, lights, stereos, laptops, etc. However, the time period for which you can run these devices depends on the type and efficiency of the batteries.

To meet your daily needs, you will need a battery with 100 Ah and 12V. The longer the battery provides the backup your devices will be powered.

**5. Types of Powers**

The basic needs supplied by an inverter are the peak or surge hours, and typical, and average power usage.

**a) Surge:** The maximum power supplied by the inverter for a short time like say for 15 seconds is the surge power. Appliances with electric motors require a higher surge while they run. Refrigerators and pumps are such appliances. Different types of inverters have different ranges that are usually from 20% to 300%. In terms of time, a surge rating of 3 to 15 seconds is enough to cover almost 99% of the appliances.

**b) Typical Power Usage:** This is the power that an inverter supplies continuously, and it is known as continuous rating. It is lower than surge. This factor determines how many amps does a 2000 watt inverter draws.

**c) Average Power Usage:** This is usually lesser than the surge and typical power usage. This is not a factor that you should know while selecting the inverter, but this power usage is necessary for estimating the required battery capacity. After this, your might also be curious of how many amps does a 300 watt inverter draw.
