Depending on the chosen battery system variant, the maximum power output (watts) and the stored energy (watt-hours (Wh) or kilowatt-hours (kWh)) differ.

To better visualize the stored energy of the battery system, here is a brief example: A 48V battery system with a capacity of 17kWh (17,000Wh) can theoretically provide 17,000 watts of power for one hour. Watts can be drawn until the battery is empty. This continues analogously, meaning you can draw 1700 watts for 10 hours, 170 watts for 100 hours, or 17 watts for 1000 hours.

Example: An LED lamp with a power consumption of 9W (equivalent to a 60W incandescent bulb) can be operated with a 48V 17kWh battery system (i.e., 17,000Wh) as follows:
17,000Wh/9W = 1,888 hours = 79 days = approx. 2.6 months

The actual battery life can be significantly longer because many devices – such as refrigerators or air conditioners – are not continuously operated at full power. Once the desired temperature is reached, they reduce their power or even switch off temporarily to maintain the temperature. This often extends the effective battery life three to ten times compared to the theoretical lifespan of continuous operation at full power.

The following table shows the runtimes of common appliances with our various battery systems. These runtimes refer to continuous operation of the appliances at full power.
