The Relationship Between Wattage, Voltage, and Amperage
To determine the amp rating of a 1200 watt inverter, we need to understand the relationship between wattage, voltage, and amperage. These three parameters are interconnected and can be calculated using the following formulas:
- Wattage (W) = Volts (V) x Amperes (A)
- Volts (V) = Wattage (W) / Amperes (A)
- Amperes (A) = Wattage (W) / Volts (V)
In the case of a 1200 watt inverter, we need to know the voltage of the AC output to calculate the amp rating. Common AC voltage outputs for inverters include 120V, 240V, and 480V.
Calculating the Amp Rating of a 1200 Watt Inverter
Let’s assume our 1200 watt inverter has a 120V AC output. Using the formula above, we can calculate the amp rating as follows:
- Amperes (A) = Wattage (W) / Volts (V)
- Amperes (A) = 1200W / 120V
- Amperes (A) = 10A
Therefore, a 1200 watt inverter with a 120V AC output has an amp rating of 10A.

- Maximum load requirement: Calculate the total power requirement of the load, including any startup or surge currents.
- DC input voltage and current: Ensure the inverter can handle the DC input voltage and current of the system.
- Efficiency and losses: Consider the inverter’s efficiency and losses when sizing the system.
| Inverter Wattage (W) | AC Output Voltage (V) | Amp Rating (A) |
|---|---|---|
| 1200 | 120 | 10 |
| 1200 | 240 | 5 |
In this table, we’ve illustrated the calculation for the amp rating of a 1200 watt inverter with two different AC output voltages.
Conclusion
In conclusion, a 1200 watt inverter with a 120V AC output has an amp rating of 10A. However, it’s essential to consider various factors, including the DC input voltage, efficiency, surge capacity, and environmental factors, when selecting an inverter. By understanding the relationship between wattage, voltage, and amperage, and considering additional factors, you can choose the right inverter for your application and ensure a reliable and efficient power solution.
What is an inverter and how does it work?
An inverter is an electronic device that converts DC (direct current) power from a battery or solar panel to AC (alternating current) power, which is what most appliances and devices use. It works by using a combination of electrical circuits and switches to convert the DC power into AC power that is safe and usable for most devices.
The inverter takes in the DC power, converts it to AC power, and then regulates the output voltage and frequency to match the requirements of the device being powered. This allows devices such as laptops, TVs, and refrigerators to function as they would on grid power, but using an alternative source of energy.
What is the importance of knowing the amp rating of an inverter?
Knowing the amp rating of an inverter is crucial because it determines the maximum amount of power that the inverter can supply to your devices.
