Features of photovoltaic DC surge protector:
- Improve system stability: photovoltaic surge protector can quickly consume surge voltage or current to avoid system crash, thereby enhancing system stability.
- Extend system life: By reducing the impact of environmental factors on the system, photovoltaic surge protector helps to improve system durability and extend service life.
- Improve system safety: Protect the system from damage by surge voltage and current, reduce maintenance costs and risks, and improve overall safety.
- Self-protection and fault indication function: When the protection device is aged or damaged, it can disconnect from the circuit in time, and notify the user to replace it through visual or remote signals, improving the reliability and safety of the system.
