At the well-attended Intersolar 2019 in Germany, electricity storage was the central theme. The exhibition has an incredible diversity, design, quality and complexity, from the flashlight battery to the megawatt memory for big cities, in a virtually unmanageable variety.
Here are the simplest, already very reasonably priced power storage to find that allow the PV power surplus in the sun loose time to a great own use. However, in case of prolonged power failure over several days in the rarest cases are also emergency power. In addition, usually only single-phase, at best are available.
Very flexible but already inexpensive storage systems, which perfect the own use, build an island network independently during long power outages and enable a full supply via the own PV, as well as CHPs, wind turbines.
The Electric Car As A Control Power Plant
Also, an e-car as additional storage for loading and unloading can be incorporated into these systems to substantially expand the capacity of the home storage, as Japanese Car Manufacturers impressively demonstrate with their 2Grid vehicle the electric car as a control powerhouse.
The vision of a fully independent, own energy supply with electricity storage, as well as a fully environmentally friendly e-mobility with maximum energy efficiency has become the incontestable fact.
In addition to biomass as the most valuable energy storage and use in heat power coupling, electricity and heat from the boiler and solar thermal energy, the heat pump in conjunction with PV and electricity storage has immense importance.
The solar industry is currently benefiting from a tremendous dynamism, which is driving its innovative strength. Technologies like Raycatch ltd was awarded the Intersolar Award, which has already been awarded for many times as the best in the industry.
