Electronics for Renewable Energies - TRUMPF Hüttinger Taps into New Markets

Renewable energies will only unlock their full potential where storage technologies and extended power grids are available. A new type of battery might be the key, and the vital electronics are now being developed at TRUMPF Hüttinger.

Batteries are well suited to catch and level out peaks in energy generation from wind and sun, and store the energy for later use. Currently, even e-cars are considered a possible storage solution. Battery systems directly attached to wind and solar power plants provide much more efficient solutions that are just as suitable for local use as for grid feed.

A new type of storage, known as redox flow batteries, is just being introduced to the market. These batteries use liquid electrolytes as storage media, are absolutely harmless to the environment, can be built for large scale storage capacities, and have a virtually infinite life-cycle. The downside: they take up a considerable amount of space.

Power inverters act as an interface between power generation, storage and withdrawal of electrical energy. Every photovoltaic system is equipped with a power inverter; however, readily available types are not entirely suitable for redox flow batteries. Being one of the pioneers in the field, TRUMPF Hüttinger has teamed up with the Fraunhofer Institute for Solar Energy Systems ISE to develop specially designed power inverters that are now at the prototype stage.

Stephan Mayer, managing director at TRUMPF Hüttinger, is optimistic about the prospects of his new business division: "We already see considerable interest, although the market is in its infancy." The projected market launch is early 2017.

GreenFasten™ solar panel roof mount hardware, watertight, USA made

GreenFasten™ solar panel roof mount hardware, watertight, USA made

The GreenFasten™ - GF1 system utilizes the patented watertight technology EcoFasten Solar® is known for. The flashing is fit with our EPDM rubber bushing and when used with a compatible EcoFasten Solar compression bracket (milled with countersink), a watertight seal is created, which protects the integrity of the roof. Requiring just a single fastener (lag bolt or self-drilling), GreenFasten provides the fastest install in the industry and will not void roofing manufacturer's warranties. Backed by IAPMO certification, GreenFasten delivers a mounting solution for all new or existing (retrofit) composition shingle roofs, and is the most cost-effective solution available. Like all of the solar roof mount solutions in our line of products, GreenFasten is made in the USA using recycled materials.
