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 battery inverter can be operated off-grid or supply back-up power in the event of a power outage
Stabilises voltage and frequency while reducing load imbalance, reactive power and harmonics in the local utility grid
The inverter consists of up to four IPU inverter modules (of 75 kW each with two battery strings; can be upgraded at any time)
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
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.

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.
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.
Use more energy from renewable sources and minimise feed-in.
Physical Peak Shaving
Shave consumption peaks and minimise demand rate costs. The grid connection must be able to supply all loads.
VDE FNN-certified fulfilment of grid requirements for not feeding electricity into the utility grid.
Consumption optimisation via active connection/disconnection of consumers depending on the energy generated.
Consumption optimisation via active connection/disconnection of generators depending on the energy generated in grid operation.
Charging Station Control1
Smart control of a single charge (set) point and central controls via the TESVOLT Energy Manager.
RLM Peak Shaving
A smart way of reducing consumption peaks at 15-minute intervals and making full use of storage systems.
A battery inverter with a power quality function balances fluctuations in the mains voltage, thus ensuring that facilities have consistently high mains quality and therefore operate safely.
Simultaneous use of two applications (SCO & PS RLM, SCO & ToU, PS & ToU)
Charging Station Control1
Smart control of multiple charge (set) points and central controls via the TESVOLT Energy Manager.
Depending on the weather forecast, curtailment losses from photovoltaic installations are avoided and self-consumption is optimised.
The consumers are supplied exclusively from the utility grid or entirely from their own storage systems and generators.
Time of Use
Time-dependent use of energy features and services.
Supplying a small power grid with or without connection to a public utility grid. A micro-grid consists of a battery storage system in addition to other generator systems and controllable consumers.
Storage system immediately takes over the power supply in the event of a power outage.
TESVOLT’s solution for simple off-grid systems which solely consist of a photovoltaic installation and battery system.
Direct marketer interface
The PV direct marketer transmits the control signals to the PV installation via the EMS.
1) Additional costs for project planing a incurred for more than one charging station
The Basic version is included in the battery storage system at no additional cost. It includes all the energy service functions listed. These can be combined under restrictions.
1. Restriction: only if PV and battery inverter each fulfill an energy service function.
2. Restriction: the customer can combine a maximum of two energy services).
The Pro version can be added to the battery storage system at an additional annual cost of EUR 3/kW (battery inverter output). It includes all of the energy service features listed below as well as the Basic version. Considering project-specific dependencies, these features can be combined and allow the simultaneous use of different energy service strategies.
