# What will a 2000 watt inverter run?

A good quality 2,000W rated inverter can run appliance(s) provided their total continuous and surge power consumption do not exceed 2,000 and 4,000 W.

And even then, this assumes that the inverter is well ventilated to be able to continuously power its full load.

In general, this inverter size can be expected to run any of the appliances below individually or in combination provided the actual continuous and surge power consumption do not exceed 2,000 and 4,000W respectively.

Kitchen appliances : Toaster, electric kettle, fridge, freezer, dishwasher , microwave

Power tools : Some drills and saws

Living room appliances:  TVs, home theater, computers, lighting.

There are some exceptions – the heavy duty power tools, air-conditioners, clothes dryers, water heaters that the inverter will likely not be able to run.

That said, the list above is indicative -always confirm the particular appliance’s continuous and surge power rating before connecting to the inverter to avoid overload faults and possible damage to the inverter.

### What size of DC wire for a 2000 W inverter?

In addition to confirming the power ratings of the appliances, the DC wire sizes of the inverters need to be
sized right to minimize voltage drops that can cause the inverter to fail to operate.

The 2,000W inverter DC cables should have a minimum size of 0 AWG provided they do not exceed 6 feet (1.8m) to keep the voltage drop to less than 3%.

### How many amps does a 2000W inverter draw?

The inverter draws DC amps from the battery and connected appliance draws AC amps from the inverter.

DC amp draw
A 2,000 watt inverter connected to a 12 volt battery draws 2000 ÷ 12 = 166 A at full load and 83 A at 24 volts. The cables from the battery to the inverter need to be sized appropriately to avoid damage to the wires from overheating and voltage drops.

AC amp draw
A 2,000 watt inverter rated 115 V draws 2000 ÷ 115 = 17 A at full load.

### What size of fuse for 2000 W inverter?

The maximum rating of the fuse on the DC side is 250 A dc. The fuse should be connected inline on the positive battery cable for short-circuit protection of the inverter.

### Will a 2000 W inverter run a microwave?

A 2,000W inverter should be able to run a small (0.7 cu.ft) and medium sized (1.2 cu.ft) microwave inverter.

A small 0.7 cu.ft has  a rated power draw of about 700W with a likely surge power rating of 1,400W while the medium sized inverter will likely have a typical power draw of about 1,100W and surge power of about 2,200W.

These are both within the limits of 2,000W inverter.

To be sure, you need to check that the microwave’s continuous and surge power rating are within what is supported by the inverter as this is a guide.

Inverter types for microwave
The recommended inverter type to use with a microwave oven is the pure sine wave inverter as opposed to the modified sine-wave inverter. So, make sure you hook your microwave to a pure sine wave inverter!

### Will a 2000 W inverter run a refrigerator?

Yes, a 2,000W inverter can run a refrigerator provided its continuous power rating does not exceed 2,000W and surge power of 4,000W.  Take the Danby DAR110A1BSLDD mid-sized 11 cu.ft (311 liters) fridge from Amazon.com with its estimated annual kwh rating of 249.

Its estimated continuous power rating is 249/(365 x 24) = 56 watts. Its surge power rating can be  3-7 times its continuous power rating. Working with 7 times, its likely surge power is 392 W.

Clearly, both the continuous power and surge power are within the limit of the 2,000W inverter and will be powered successfully.

Larger capacity fridges whose continuous or surge power rating exceed that of the inverter will cause an overload on the inverter and not run.

To be sure whether an 2,000W inverter can run a particular fridge, confirm that the electrical specifications for your fridge or freezer are within those of the inverter.
