Suitable for any application

TESVOLT specialises in high-performance lithium storage systems which are particularly suitable for application in commerce and industry. Thanks to a highly flexible modular system, our various battery sizes can be combined in any way required – with a capacity ranging from 10 kWh to up to several megawatt-hours. They take up only a small amount of space and can also withstand extreme temperatures of between 5 and 40 degrees – and can be installed almost anywhere.

You decide how fast your storage system charges!

You choose the speed of your battery storage system. Select the number and output of the charge controllers, depending on the capacity of your storage system, and desired charging speed. TESVOLT batteries can be fitted with up to 36 charge controllers with a total output of up to 216 kilowatts. The more controllers and the higher their output, the more power the system stores in a correspondingly short time.
