Inverter Size Calculator | Find Your Perfect Power Match
Quickly size your campervan inverter. Add appliances, see min & max loads, and compare value vs premium options. Efficient, reliable, & easy.
There is a simple method to calculate how much power your inverter is using: For 12-volt inverters, divide the connected load by 10; for 24-volt inverters, divide by 20. Example: How much does an inverter consume with a 400 W load connected? For a 12 V inverter such as a Mass Sine 12/1200, consumption will be 400/10 = approx. 40 amps.
An inverter uses a small amount of energy during the conversion process. The difference between the input power and the output power is expressed in percentages. The efficiency of modern inverters is more than 92 %. This means that a maximum of 8 % of the power consumption is used to convert battery voltage to 230V/50Hz.
A 1000w inverter fully loaded for one hour will draw around 90 amps from a 12v battery. To replenish those 90 amps, you'd need about 300w of solar panels receiving 4 good hours of sun. Remember, you can only take out of your battery what you put in. Inverters for standard 12v campervan systems typically max out around 3000w.
Remember, you can only take out of your battery what you put in. Inverters for standard 12v campervan systems typically max out around 3000w. Manufacturers rarely produce larger models due to battery drain and wiring complexity. Similarly, 24v and 48v systems generally support inverter sizes up to about 4000w.
