TPS flex lithium storage system

The all-rounder with the plus for performance

Currently extended delivery times and increased prices!

The insufficient availability of electronic components is currently leading to extended delivery times.

The situation has been further aggravated by the current crisis in Ukraine. The shortage of raw materials has led to a sharp rise in prices in all areas. Unfortunately, we have also been directly impacted by these price increases without prior notice from our suppliers.

Therefore, we are also forced to increase our prices with effect from 14 March 2022.

We hope to be able to return to our usual delivery times and prices as soon as possible. For further information on your orders, please get in touch with your personal contact!

Areas of application

The TPS system has a fully modular design, from the battery modules to the container. That makes it adaptable, with a long lifespan for high efficiency.

Self-Consumption Optimisation

Use more energy from renewable sources and minimise feed-in.

Peak Shaving

Shave consumption peaks and minimise demand rate costs.

Time of Use

Time-dependent use of functions.


Simultaneous use of two applications: Either LSK & EVO, or LSK & Time of Use, or EVO and Time of Use.

Ancillary Services

Remote control of active and reactive power.

PV-Diesel-Hybrid Optimisation

TESVOLT solutions have the option of making the utility grid available while counterbalancing production and consumption peaks. This keeps diesel generators operating as efficiently as possible to minimise diesel costs.

Forecast-Based Battery Charging

Depending on the weather forecast, curtailment losses from photovoltaic installations are avoided and self-consumption is optimised.

Direct Marketer Interface

Gives access to direct marketers for the purposes of marketing electricity from renewable energy sources.

Modular Principle

The TPS flex is available in a total of six variants. Except for the smallest system, the capacity of all other variants can be increased by 4.8 kWh per battery system with the help of an expansion set. Two different container sizes (10 ft and 20 ft) are available.
