What can a 4000 watt inverter run?

A 4000w power inverter has the ability to power on something as small as a laptop or something as big as a refrigerator. It is capable of running a combined load of up to 4000 watts.

There is a wattage rating that is associated with most electrical appliances; this can help you to determine how much power is needed to operate them. The wattage rating can be easily found on their labels.

It is always a good idea to have oversized inverters with the capability of handling 15 to 20% overloads for a short period of time.

Can 4000 watts inverter drive a 1.5 horse power AC water pump motor?

A 4000 watts power inverter should have no problem powering a 1.5Hp water pump. For continuous operation, the pumps should draw only about 1200 to 1300 watt depending on the efficiency of the motor.

Where difficulty may arise is when the motor will start to draw 4 to 5 times its continuous power which would be around 5000 to 6000 watts, however, the inverter will control that peak draw within its output rating limit and the motor will start fine, it might just take a little longer to get up to speed.

How many amps does a 4000 watt inverter draw?

Power inverters convert 12v DC from batteries to 110v AC for running electrical appliances.

The current drawn by a 4000 watts power inverter can be calculated as follows:

Watt(Power) = Volts (Voltage) X Amperes (Current)

Current drawn by a 4000W inverter (4000/110) A = 36.4 amps
