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.
TESVOLT battery storage systems can be combined with renewable energy sources such as photovoltaics or wind power to provide an off-grid electricity supply that’s not only greener, but also more cost-effective.
While renewable power generators are often the lowest-cost alternative to diesel and CHP plants, they do have one major disadvantage: if there is no wind, or during darkness, wind power and solar generators are unable to provide electricity. This is where battery storage systems offer a simple solution. If more power is produced than is needed, it is stored in the battery. As soon as more power is required than can be provided by the wind and sun, the storage system goes into operation and provides continuous power.
Although procurement costs for a diesel generator are considerably lower than for a TESVOLT battery storage system, the variable costs for the storage system are very low. The systems usually pay for themselves in just a few years.
Auch in Kombination mit einem Dieselgenerator helfen Batteriespeicher die Kosten zu senken. Ineffiziente Starts und damit auch die Kaltlaufzeit des Generators werden auf ein Minimum reduziert, die unterbrechungsfreien Laufzeiten verlängert und so Brennstoffbedarf, Verschleiß und Wartungsaufwand deutlich verringert. Werden zusätzlich auch regenerative Stromerzeuger eingesetzt, wird der Generator nur dann benötigt, wenn der Batteriespeicher leer sein sollte.
