In most cases, you can calculate whether your supplies are sufficient or not.
Whether it is food, fuel or electrical energy is usually irrelevant.

However, it is important to know your exact consumption and not to cheat yourself.
Physical circumstances may also need to be taken into account.

We would like to help you calculate your energy requirements and have prepared the Excel sheet below for this purpose. All you need to do is enter the power and operating time of all your appliances.


Whether you are using 230V alternating current or 12, 24 or 48V direct current, you can use this sheet to easily calculate your daily requirements. If desired, you can also use it to determine the required battery capacity.

This sheet is generally intended for calculating energy in connection with batteries. In other words, for the calculation of off-grid objects such as vehicles for travelling / camping and industry, as well as for ships or off-grid island systems.

If you want to determine the energy requirements of your house, this is also possible with the help of our template. In most cases, however, it makes more sense to measure consumption and record it on site.
