As renewable energy becomes more widespread, the combination of photovoltaic (PV) systems and energy storage has become a hot topic in the energy sector. Integrated solar and storage systems not only improve energy efficiency but also enhance the stability of energy supply. However, the safety of electrical equipment is crucial in such complex systems, especially the selection and application of surge protection device (SPD).

Surge Risks in Integrated Solar and Storage Systems

      PV systems are often exposed to outdoor environments, making them vulnerable to lightning strikes and transient overvoltages from the grid. Energy storage systems must also deal with transient voltages that may occur during battery charging and discharging processes. Hence, surge protection is essential for the safe operation of integrated solar and storage systems.

Application of Low-Voltage Surge Protectors

      Low-voltage surge protector effectively prevent damage from transient overvoltages. For integrated solar and storage systems, the selection of surge protectors should consider the following:

      1. Response Time: Fast response time ensures effective protection before the voltage surge reaches the equipment.

      2. Current Capacity: PV and energy storage equipment can generate large surge currents, so surge protectors with high capacity are necessary.

      3.Installation Points: Installing surge protectors at critical points in the system, such as inverters and battery access points, can effectively reduce surge risks.

      In integrated solar and storage systems, low-voltage surge protectors not only enhance operational stability but also extend the lifespan of the equipment. For customers, selecting the right surge protection device is key to ensuring the safe and stable operation of the system.
