Power inverters convert DC power to AC power, which is what you need for your devices. If you want to hook up appliances and other devices that run on AC to your off-grid solar system, you will definitely need an inverter. Many RVers aren’t sure how many appliances can their inverter run, so in this blog, I’ll answer the question of “what will a 3000 watt power inverter run?”
A 3000-Watt inverter can run 110 appliances, many of which will be able to run only on a 12-Volt DC connection. Some appliances will run on 20-Volt instead, and this includes those that run off a charge controller.

What a 3000 Watt Power Inverter Can Run
The following is a list of appliances that it can run:
B. Computer Peripherals
C. TVs and DVD Players
D. Various Appliances and Tools for your Camper, including oscillating fans, microwaves, coffee makers, cell phones, electric shavers
E. Small Fans and Heaters
F. A Larger Voltage Appliance or Device that runs on a 12-Volt DC Power Source
From a more detailed list, here are some appliances that can be run on either 20- or 12-Volt:
A. Hair Dryers (some run on 12-Volt)
B. Small Microwave (some run on 20-Volt)
C. Small Oscillating Fans (some of these will only run on 12-Volt)

D. Small TVs (some run on 20-Volt)
E. Small Hair Straightener (some of these can run on 12-Volt)
F. Small Toaster (some will run on 12-Volt)
G. Small Coffee Maker (some will run on 12-Volt)
H. Small Electric Griddle (some will run on 12-Volt)
So can we use all appliances at the same time? You can use a mix, but not all at the same time.
Here are some of the limitations:
A. The laptop you’re using will be the biggest limitation on what you can run. This is because it will need a constant 12-Volt power to run, and your 3000-Watt power inverter doesn’t produce enough amperage to support that.
B. The TV will be your second limitation because it will use too much amperage.
C. The microwave, coffee maker, toaster, and many small appliances and tools run on 12-Volt DC power. Unless you’re using the inverter to charge your batteries, you won’t have enough power available for all of these to run at the same time, especially if you’re running something else like a laptop or a TV at the same time.
D. The hairdryer, oscillating fans and small electric griddle will use a lot less power than the other appliances listed above, so you can run more of these at a time.
E. If you’re running 12-Volt DC appliances like the microwave or coffee maker, when the inverter runs out of juice, both appliances will be shut down. So if you have these two devices on at the same time (or no devices on), make sure you don’t run out of power for either.
