Why BESS Systems Need Lightning Protection Solution?

Why BESS Systems Need Lightning Protection Solution?

Lightning protection for BESS energy storage systems & photovoltaic power plant is not only a safety issue, but a strategic investment to ensure long-term lithium energy storage power plant and solar PV farm functionality, sustainability and efficiency.

Battery energy storage systems (BESS)/ photovoltaic power farm are a key technology in the transition towards a more sustainable green energy model. These systems enable the storage of surplus energy generated by renewable sources such as solar or wind power, ensuring its availability during periods of higher demand. In addition, BESS photovoltaic power plant help stabilise the electricity power grid, reduce consumption peaks, and provide energy backup in critical situations, making them an essential component of modern electricity infrastructure.  

At LSD, we offer customised studies that enable us to implement comprehensive and efficient solutions, ensuring compliance with the regulations in force in each country.

External protection: protection systems based on conventional franklin lightning rods with limit protection radius or REAZY® LY-ESE3.0 pre discharge(ESE Early Streamer Emission Air Terminal) lightning rods with much larger protection radius are designed to safely capture and channel atmospheric discharges to the ground, ensuring long-lasting protection in accordance with international standards NF C17-102:2011,UNE 21186:2011 and IEC 62305. These ESE lightning protection system are complemented by down conductors and earthing systems(copper earthing rod,earthing grounding enhancement compound that ensure effective current dissipation, minimising structural and electrical risk from direct lightning strike.

Internal protection: surge protection devices, designed in accordance with IEC 61643, safeguard critical equipment such as converters and battery management systems (BMS),PCS,EMS,BCU. In addition, equipotential bonding ensures uniform current dissipation, protecting both equipment and personnel. 

Preventive protection: The REAZY-SMART STORM® early warning system, compliant with IEC 62793:2020, anticipates thunder storms by monitoring the atmospheric electric field, enabling proactive measures such as disconnecting sensitive equipment or activating safety protocols.

Why BESS Systems Need Lightning Protection Solution?

1.BESS systems contain critical electronic components, such as power converters and battery management systems (BMS), which are highly sensitive to surges and direct lightning strikes. 

2.Lightning can generate sparks or overheating, potentially triggering fires in installations, specially in systems containing lithium batteries. 

3.Investing in a lightning protection system significantly reduces the costs associated with repairs, equipment replacement, and downtime, maximising BESS perfomance and optimising return on investment.

4.Lightning damage can cause significant disruptions to power supply and system operation. Proper protection minimises the risk of costly and prolonged operational dowtime.
