The next thing you need to consider is the size of your inverter. The output wattage will be printed on the device and usually starts at about 100 watts.
This is usually the labeled rating of the inverter, so if you’ve calculated you need a 3000w inverter, that means you need a device that can provide 3000w of continuous power.
Inverters can provide a greater surge of power in short bursts. This is especially useful for appliances that demand a power surge on startup, like a compressor fridge or induction cooker.
Most RV and campervan electrical systems have a 12v battery bank. Some have 24v, and even fewer have 48v. All of the inverters on our list are 12v models as it’s the most common battery bank voltage for recreational vehicles.
