What Will a 750 Watt Inverter Run?
These inverters have a maximum capacity of 750 running watts per hour and a surge capacity of up to 1500 watts, which can be sustained for only a few seconds.
Appliance Compatibility and Power Calculation
These inverters can support a combination of appliances as long as the total power consumption remains below 750 watts per hour. The newer inverters are 90-95% efficient, resulting in actual available wattage ranging from 675 to 712 watts. To determine appliance compatibility, consult an appliance wattage chart and calculate power requirements.
Appliance power consumption is typically measured in watts, although amps may also be listed. The amp draw per hour depends on the voltage.
Conversion Formulas and Examples
To convert between amps and watts, the following formulas can be used:
Amps x Volts = Watts
Watts / Amps = Volts
Watts / Volts = Amps
Example 1: A 750-watt inverter with a 320-watt load running on 120V AC power will draw 2.6 amps. 320 / 120 = 2.6 amps
Example 2: Another 750-watt inverter running a similar load on 24V batteries will pull 13.3 amps. 320 / 24 = 13.3 amps
These calculations provide estimates. It is important to consider inverter efficiency and factor in runtime. Multiply the total watts by the inverter rating to obtain an estimate.
Efficiency significantly affects power consumption. If you have a 450-watt load and a 90% efficient inverter: 450 / 0.90 = 500 watts The 450-watt load will utilize 500 watts due to efficiency losses. Running an inverter at full capacity is not recommended as it can be dangerous, and there may not be sufficient power available.

750W Inverter Battery Runtime Guide
Here’s a convenient reference for running various power loads on an inverter and their expected duration. This guide assumes the inverter operates on batteries, which will be completely depleted by the end of the specified runtime.
- 60W ceiling fan: 12 hours
- 60W light bulb: 12 hours
- Refrigerator: 8 hours
- 40-inch TV with movie player: 5 hours
- Slow cooker: 3 hours
- Laptop, printer, speakers, router, portable fan, LED lights: 2 hours
- 600W microwave: 1 hour
- Well pump: 1 hour
- Blender: 1.5 hours
Here are some additional points to consider regarding this 750W inverter battery runtime guide:
- The power consumption values provided are estimates. For instance, the laptop in the example utilizes 200 watts, which is typical for business applications and web browsing. However, a gaming laptop will require more solar power to operate effectively.
- Many appliances exhibit variable usage patterns. For example, while a blender may consume approximately 700 watts per hour, it is typically used for only a few minutes or seconds at a time. This applies to other appliances and tools as well, meaning their actual usage may not be as high as their maximum power rating suggests.
- The chart assumes that the inverter has a power capacity of 750 watts, which is equivalent to a 62.5 ampere-hour (Ah) 12V battery or a 31.25Ah 24V battery. Rounding off to the nearest available battery size, this would be approximately 75Ah for 12V systems or 35Ah for 24V systems.
- You have the flexibility to mix and match appliances based on your specific requirements. There is no one-size-fits-all solution since each individual has different appliances and tools with varying power demands.
- Due to manufacturing differences, power consumption may vary among appliances, even if their specifications appear the same. Some appliances may be more energy-efficient than others.
- Inverters perform optimally when shorter and thicker wires are used. By minimizing the length of cables between the inverter and the batteries, less energy will be lost during the conversion process.
After going through this 750W inverter battery runtime guide, unraveling the number of batteries you need for a 750 Watt inverter also becomes necessary.
How Many Batteries Do I Need For a 750 Watt Inverter?
If you are connected to a grid-tied system, you won’t require a battery bank as the inverter can operate directly from the main power supply. As long as there is electricity available, your appliances will continue to function without interruption.
However, if you are in an RV or a solar-powered mobile home, the inverter’s power supply will be sourced from the battery bank. To determine the number of batteries needed, you can use the following formula:
Appliance Watts x runtime = total Watts
Total watts / DC volts = amps
Let’s consider an example with a 12V 750 watt inverter. If you have a load of 750 watts, the inverter will run for approximately an hour, depending on its efficiency rating. The system will draw 62.5 amps (750 / 12 = 62.5). Assuming you have a 75Ah battery, the runtime will be around 1.2 hours (62.5 / 75 = 1.2).
Keep in mind that running the inverter on a 75Ah battery for 1.2 hours will result in a complete discharge. This is not recommended for flooded lead-acid (FLA) batteries, as they are typically designed to be recharged at 50% depth of discharge. Following this guideline, a 12V 150Ah battery would be required to power a 750 watt load for 1.2 hours without fully discharging the battery.
Now, it’s also necessary for you to find out how many Amps can a 750 Watt inverter draw. So, let’s find this out in the next question.

How Many Amps Can a 750 Watt Inverter Draw?
To determine how many Amps can a 750 Watt inverter draw, it is important to consider the voltage of the inverter, which could be 12 volts, 14 volts, 24 volts, or 28 volts.
While many inverters with a power rating of 750 watts typically operate at voltages higher than 12 volts, for the purpose of this calculation, we will assume a voltage of 12 volts, which is the lowest value.
Therefore, the amperage of the inverter at 100% efficiency would be calculated as follows: 750 watts / 12 volts = 62.5 amps.
Considering that achieving 100% efficiency is unlikely, let’s assume an efficiency of 80%. Consequently, the amperage would be approximately 62.5 amps / 0.8 = 78.13 amps.
After understanding how many Amps can a 750 Watt inverter draw, let’s also try to figure out how to safely run appliances on the 750 Watt inverter.
How to Safely Run Appliances on the 750 Watt Inverter
To safely run appliances on the 750 Watt inverter, please consider the following guidelines:
- Install the inverter in a well-ventilated area to prevent overheating.
- Adhere to the inverter’s specified continuous and surge power ratings. Exceeding these limits may cause improper appliance functionality and potential damage to the inverter.
- Determine the maximum runtime of the inverter at its full power output. Some inverters can only sustain their continuous power rating for a limited period, which could be an hour or less.
- Whenever possible, aim to utilize the inverter at up to 80% of its full power rating. For instance, if you have a 750 watt inverter, try connecting appliances with a maximum power draw of around 600 watts (80% of 750 watts).
By following these recommendations, you can ensure the safe and efficient operation of appliances connected to the inverter.
