Private Storage Systems
Photovoltaic electricity use, even when no sun-with a battery system as a temporary storage works like that: In evening, the energy will be consumed by the house or will be recalled by the energy companies when the demand is high. For owners of photovoltaic systems, the option is attractive to consume the electricity generated itself. PV systems with smart inverters and batteries help to increase their own consumption as well as to secure its own supplies. The Federal Environment Ministry (BMU) promotes within the funding priority 'optimization of energy supply systems' research and development of uninterruptible power supply(UPS), for temporary storage and consumption of PV electricity. Initial solutions are already available and a durable and affordable storage solution will be further researched.
