TS-I HV 80 E lithium storage system

The allstar with the E factor

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!

Extremely safe cell technology

Versatile, economically efficient
and powerful without compromise

The TS-I HV 80 E satisfies even the highest performance and economic efficiency standards. Are you interested in dynamic peak shaving, Time of Use or back-up power applications, either on-grid or off-grid? Then the TS-I HV 80 E is sure to impress you. With output well into the megawatt hour range, it’s equipped to handle the toughest jobs and, thanks to the active filter technology, it also improves the local power quality – sustainably and almost incidentally. High-quality battery cells from the automotive industry and innovative technologies such as the DynamiX Battery Optimizer make the TS-I HV 80 E series one of the most durable products on the market.

The integrated TESVOLT PCS industry inverter

Black Start-Capable
The battery inverter can be operated off-grid or supply back-up power in the event of a power outage

Power Quality
Stabilises voltage and frequency while reducing load imbalance, reactive power and harmonics in the local utility grid

Modular Principle
The inverter consists of up to four IPU inverter modules (of 75 kW each with two battery strings; can be upgraded at any time)

Control Rate
Response time to power requirements in the utility grid in milliseconds

Maximum Power Density
Potential for up to 340 kW with a footprint of just 0.54 m2

Control and monitoring made easy
The TESVOLT energy management system

All energy flows can be recorded, controlled and monitored second-by-second with the innovative TESVOLT energy management system – consisting of the TESVOLT Energy Manager and myTESWORLD portal. By setting individual operational strategies, you can combine a wide variety of applications and thus perfectly adapt the system to the needs of trade and industry.

The TESVOLT energy management system is available both as a free Basic version and as a fee-based Pro version with valuable additional functions, such as the multi-use feature and minute-by-minute data evaluation for even greater transparency.

Application areas


Sites that are far from the utility grid, such as mountain huts, have until recently needed a diesel generator or combined heat and power unit to obtain a continuous power supply. Although these technologies can be procured relatively cheaply, their maintenance and operating costs are higher.

The TS-I HV 80 E can be combined with renewable energy sources such as photovoltaics or wind power to form a stand-alone system, thus providing an off-grid electricity supply that is not only greener, but also more cost-effective.


Because the TS-I HV 80 E allows the battery to be used in multiple ways concurrently, two operational management strategies can be combined: self-consumption optimisation (SCO), peak shaving (physical or RLM) or Time of Use (ToU).

The storage system can be configured as needed, with the ability to define a specific storage range for each use case. This maximises the storage system’s service life, meaning that investments will pay for themselves sooner.

Back-Up Power

Power outages are a crucial consideration for many businesses. Ventilation, heating, cooling and production machines cannot be allowed to go idle, as this risks causing economic losses. Often, emergency diesel power generators are installed as a backup, but these incur high fuel and maintenance costs, as well as generating noise and emissions.

By contrast, the TS-I HV 80 E provides a clean, reliable source of back-up power and helps cut operating costs by a considerable amount.

Overview of all application areas

Free Basic Version

Self-Consumption Optimisation

Use more energy from renewable sources and minimise feed-in


Create your own power grid independently of energy suppliers, for example by combining a photovoltaic installation and TESVOLT storage solution


Physical Peak Shaving

Shave consumption peaks and cut demand rate costs

Back-up Power

The storage system immediately takes over the power supply in the event of a power outage

Zero Feed-In

Fulfils the normative guidelines (Germany) stipulating that no power can be fed into the utility grid

Load Control

Actively switch consumers on and off depending on generation and consumption (see compatibility list)

Generation Control

Generators such as CHPs can be actively switched on or off and controlled for greater independence from energy suppliers

Charging Station Control1

Smart interconnection of the charging station and central controls via the TESVOLT Energy Manager. This means charging processes can be digitally recorded and controlled

Fee-Based Pro Version

RLM Peak Shaving

A smart way of reducing consumption peaks at 15-minute intervals and making full use of storage systems

Power Quality

Keep the utility grid in a constant, correct frequency range. Harmonics are counterbalanced dynamically, improving the power quality in the system



Simultaneous use of two applications (SCO & PS, ToU & PS, ToU & SCO)

Charging Station Control1

Smart interconnection of the charging station and central controls via the TESVOLT Energy Manager. This means charging processes can be digitally recorded and controlled

Forecast-Based Charging

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

Semi-Off-Grid Operation

Consumers are fed either from the grid alone, or else up to 100% from a storage system and renewable energy installations. In-house energy sources are never connected to the public utility grid.


Time of Use

Time-dependent use of functions.

1) Additional costs for project planing a incurred for more than one charging station
