Utility scale Energy Storage Systems. Low-voltage products and solutions


Energy Storage Systems come in a variety of sizes and face very different needs. Taking into consideration large installations and focusing our attention in the Battery Protection section, we can notice that, like in PV systems, ESS can use DC voltages from about 600V DC up to 1000V DC or more (even 1500V DC). Nominal DC current is also comparable with PV systems, and the layout of the plant can also be similar to them (basic battery modules are connected in series,like PV strings). ABB low-voltage portfolio allow for a wide spectrum of configurations.

A large ESS can be described in its basic components in the following schematic:
