If you have a photovoltaic system on your roof, a battery storage unit can ensure that the self-generated electricity is available even when the sun isn’t shining–such as in the evening. However, for the storage unit to function reliably for as long as possible, the right location is crucial. A poor choice of location can significantly shorten its lifespan. myHOMEBOOK explains what to consider when storing the battery storage unit.

Store Instead of Feed
Photovoltaic systems often generate more electricity during the day than is directly consumed in the household. A battery storage unit allows this surplus to be stored and used later. This has several advantages: It reduces feeding into the public grid, increases the share of self-consumption, and makes you less dependent on electricity prices.
Indoors Instead of Outdoors: Location Choice Crucial
To ensure the battery storage unit operates optimally and is not damaged by external influences, it should be installed indoors, according to the information program Zukunft Altbau, which is supported by the Ministry of the Environment of Baden-Württemberg. The room where the battery storage unit is kept should be dry, well-ventilated, and maintain a constant temperature, advises the program.

Heated Basements and Garages Are Not Good Places
The ambient temperature is particularly important: Temperatures that are too high or too low can impair the function and lifespan of the battery. Zukunft Altbau therefore recommends that the ambient temperature should not fall below zero degrees or exceed 20 degrees Celsius. A warm heating basement or a cold garage is therefore unsuitable for storing battery storage units.
Observe Manufacturer’s Instructions
However, the exact tolerance range depends on the specific battery storage unit. Consumers should therefore definitely pay attention to the manufacturer’s technical specifications. These usually contain specific information on temperature ranges and humidity that are crucial for safe and efficient operation.
