Does container battery energy storage need lightning protection

Do I need an external lightning protection system?

Therefore the need for optimized and reliable electrical protection against the influence of lightning and surge events becomes mandatory. A risk assessment per IEC 62305-2 should first be performed to understand better if an external lightning protection system (LPS) is required.

How many kWh can a battery storage system store?

Such systems have storage capacities upwards of approximately 50 kWh. They are constructed as standalone objects, either indoors or outdoors and contain all the components necessary for their operation (e.g. battery systems, power electronics, energy management, extinguishing system, air conditioning, containers, etc.).

What is a container battery storage system?

The container battery storage systems store the power generated, e.g., by photovoltaic systems and wind turbines, and feed it back on demand. Thanks to decentral storage, they also reinforce network stability and can be used by the network operator to provide balanced power.

How to protect high-end electronics in storage containers?

In addition, battery storage for the power grid forms the basis for energy management (so-called “peak shaving”). In order to provide optimum protection for the high-end electronics in storage containers, one needs a comprehensive lightning and surge protection system.

What is a battery storage system?

Battery storage systems store excess energy produced by Renewable Energy systems such as PV or Wind and store it for use when needed. This counterbalances the fluctuation between energy production and demand for electricity.

What happens when lightning strikes a storage system?

Distant lightning strikes or so-called indirect lightning strikes lead to conducted partial lightning currents (impulse waveform 10/350 μs) in the supply lines, or also to induced / capacitive couplings (impulse 8/20 μs) in the electronic components of the storage system itself (so-called LEMP = Lightning ElectroMagnetic Pulse) (Figure 1).
