🔋⚡ How Does PCS Overvoltage Protection Protect a BESS?

When the power grid experiences abnormal voltage conditions, the PCS becomes the first line of defense between the grid and the battery system.

Without proper protection, voltage surges can affect:

❌ Power semiconductor switches
❌ DC-link capacitors
❌ Transformers
❌ Battery system reliability

A complete PCS protection design includes:

✅ Fast surge protection
✅ Overvoltage monitoring
✅ Ride-through capability
✅ Smart reactive power control
✅ Protection coordination between transformer and inverter

As renewable energy penetration increases, advanced PCS protection becomes essential for safer and more stable energy storage systems.
