Calculations Copyright © 2015 Sensata Technologies - The maker of MAGNUM-DIMENSIONS ® inverters.
We have developed the inverter calculator below as a general guideline to illustrate what loads you can run on your 12VDC vehicle's platform. The conclusions made in this calculator are conservative estimations to illustrate the wattage you need compared to the power your vehicle can deliver. Your results may vary.
Derived wattages are based on the assumption you are using a Magnum-Dimensions® Pure Sine, UL listed inverter.
Note: Using a modified sine wave (MSW) inverter will increase the power drawn by the load and the inverter on the batteries and alternator.
For more information, please contact a Magnum-Dimensions representative here.
Select the devices you will be using.
Enter the amps of your alternator.
Enter the number of batteries and Ahr Rating.
Below is a summary of the load and vehicle information you entered above. This is a generalized understanding of your power system. Your individual results will vary.
