A neighborhood battery is a central battery in the neighborhood. This means that self-generated energy that is not used immediately is stored centrally nearby. This allows residents to use the generated electricity at a later date. This allows participants to make maximum use of their own energy.
Did you know that solar panels do not always achieve their profitability?
Many neighborhoods built in the 1960s and 1970s are not suitable for a high percentage of PV panels. In districts connected via a single phase, the PV converters often reach their maximum voltage and therefore switch off.
This has a major impact on the payback period for the owners of the PV installation and changing this situation is often too difficult. Connecting the houses to a three-phase network will help, but it would also mean that the owners have to buy a three-phase PV converter.
A neighborhood battery is a good solution because it can charge the individual houses on the 1-phase grid and thus generated energy can be stored. Depending on the agreement with the local grid operator, this energy can be returned to the original generating households or used for other applications such as peak shaving, energy trading or FCR.
