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 energy features and services.

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.


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

1. DC Distribution

2. Battery Racks

3. Air Conditioning
