TS-I HV 80 Lithium Storage System

Battery storage system, inverter and energy management in one system

TESVOLT TS-I HV 80 storage systems are fitted with an integrated 3-phase battery inverter.

The inverter is available in four power levels and can be upgraded at a later date. It can also be operated in parallel with up to five cascaded systems.

Combined with the innovative TESVOLT energy management system, TESVOLT TS-I HV 80 systems adapt perfectly to the requirements of trade and industry.

TESVOLT energy management offers not only the most diverse, combinable range of applications, it also enables comprehensive monitoring, intelligent consumer control, and improved power quality.

This flexibility increases the sustainability of your TESVOLT battery storage system and, thanks to multi-use application, its profitability as well. TS-I HV 80 systems can also be used “off-grid” to form grids outside the grid connection.

The all-rounder

Benefits of TESVOLT inverters

  • Black start capable – the battery inverter can be operated off-grid or supply back-up power in the event of disruption to grid supply
  • Active filter – 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 85 kW each, can be upgraded at any time)
  • Control rate – response time to power requirements in the network in milliseconds
  • Maximum power density – potential for up to 340 kW with a footprint of just 0.54 m2

Benefits of the TESVOLT energy management system

  • Universally applicable – off-grid, back-up power, peak load shaving, increased self-consumption, multi-use, power quality, time of use, forecast-based charging, consumer control, generator control, grid services (e.g. PBP)
  • Multi-use – combine various applications such as increased self-consumption, peak load shaving, time of use, back-up power and others
  • TESVOLT monitoring portal – real time control and monitoring of the battery storage system/inverter’s function and savings (energy and CO2)
  • Long-term flexibility – new functions can be added even after many years
  • If WLAN, a mobile wireless network or other wireless interface is available, updates can be easily implemented over-the-air

Application areas

The TS-I HV 80 battery storage system with integrated inverter and the TESVOLT energy management system can be used in more application areas than ever before, increasing the benefits and profitability significantly.

Increase in self-consumption

Use more of the power you generate and cut your electricity costs

Peak load shaving

Cap your consumption peaks and save money thanks to reduced grid connection

Charging station infrastructure

Combine applications such as peak load shaving, self-consumption and grid services with further options including control of e-charging points, overcharge safety devices, charging with excess power, and prioritisation of individual charging stations

Multi-use applications

The Pro version also offers peak load shaving, optimisation of self-consumption, and back-up power (off-grid).

Grid services

Manage frequency, reactive and active power, and balance utility grid fluctuations. (Pro version, project-based)

Time of Use

Store power in the battery during favourable lower tariff periods and use as required when expensive tariffs apply.

Power quality

Active filter ensures utility grid improvements. Can also be combined with other applications

Off Grid

For forming off-grid networks and microgrids

Back-up

Includes black start capability

Generator control

For combined heat and power units and diesel generators, for instance

Consumer control

Domestic and commercial consumers with dynamic output restriction on the line connection (black-out protection) and heat pump control with adjustable turn-on threshold and turn-on delay

Forecast-based charging

To avoid curtailment losses in the photovoltaic installation
