Bidirectional inverters for battery systems
Bidirectional inverters for battery systems
TRUMPF Hüttinger


Charging and discharging technology perfected

Perfect design for your battery storage system

The bidirectional battery inverters TruConvert from TRUMPF Hüttinger were specially developed for use with redox flow batteries. They are suitable, however, for any other batteries, for example lithium-ion batteries or lead batteries. They stand out for their fast response time and very high efficiency, and enable the direct connection of low-volt batteries to the 3-phase alternating current network.

Even for load jumps above 200%, the battery inverters react in less than 10 ms. Efficiency of ≤ 96% enables the very energy-efficient operation of your battery storage.

Short reaction times

Even for load jumps of more than 200%, the battery inverter responds in less then 10 ms.

High efficiency

Efficiency of ≤ 96% enables the very efficient operation of the battery storage.

Ideal for micro-grids

The ability to handle unbalanced loads and idle power ensures high network quality in island networks.

Charging and discharging from 0 V

No external power pack is needed to condition a redox flow battery.

Robust/industrial design

The battery inverters are designed to have a service life of at least 20 years.


Parallel connection of individual modules for high power requirements.

Efficient and cost-effective use of battery storage systems

Efficient and cost-effective use of battery storage systems

Bidirectional inverters enable the efficient and cost-effective use of battery storage systems. They convert the alternating current into direct current, which is fed into batteries (e.g., redox flow or lithium ion batteries). The stored energy can be retrieved at any time, if necessary, and converted back into alternating current.

Optimized for use with redox flow battery storage systems

Maximum efficiency for your battery storage system

With a power output of 8 kW to 25 kW, the bidirectional inverters are well-suited for both small and large battery storage systems and can be used around the world with their variable line voltage, without the need to adapt them. Efficiency of ≤ 96% over a broad voltage range enables the particularly energy-efficient operation of your battery storage. They can be connected in parallel and can therefore be adapted to high powers without problem. They also have an internal potential isolation to safely isolate the battery from the network.
