Frequently Asked Questions

Q1: What is the purpose of a DC disconnect switch in a solar PV system?

A DC disconnect switch is used to safely interrupt the direct current flow between the solar panel arrays and the inverter. It is essential for system maintenance, troubleshooting, and emergency shut-offs.

Q2: Why is waterproofing critical for outdoor isolator switches?

Outdoor electrical installations are exposed to rain, dust, and humidity. High waterproof-rated enclosures (such as IP66) protect the internal contacts from corrosion and short-circuits, ensuring long-term reliability and safety.

Q3: How do I choose the correct current rating (20A, 32A, 63A) for my installation?

The choice depends on the maximum output current of your solar strings. It is recommended to choose a rating that matches or exceeds your system's design requirements, factoring in safety margins according to local electrical codes.

Q4: Can these switches be used for EV charging and energy storage systems?

Yes. These switches are specifically designed to safely manage high-voltage DC circuits, making them highly suitable for isolating EV charging units, battery storage modules, and other new energy applications.

Q5: What does the pole rating (e.g., 2P, 4P) signify?

The number of poles indicates the number of separate electrical lines the switch can disconnect simultaneously. A 2P switch disconnects two lines (positive and negative of a single circuit), while a 4P switch can isolate four lines, useful for dual strings.
