在太阳能装置中使用VIOX VOPV直流隔离开关的优势

The primary function of a DC isolator switch is to provide a safe disconnection point between solar panels and inverters. The VOPV ELR1 series excels in this role with its rapid arcing time and secure locking mechanisms, significantly reducing electrical hazards during installation, maintenance, or emergency situations.

Improved System Longevity

By incorporating high-quality components and robust environmental protection, the VOPV isolator switch contributes to the overall longevity of the photovoltaic system. The switch’s durability means fewer replacements over the system’s lifetime, reducing maintenance costs and system downtime.

تعمیر و نگهداری ساده

The ability to padlock the switch in the OFF position provides maintenance personnel with added security when servicing the system. This feature ensures that the circuit remains disconnected throughout maintenance procedures, eliminating the risk of unexpected reconnection.

گزینه‌های نصب متنوع

With multiple connection possibilities and both 2-pole and 4-pole configurations available, the VOPV isolator switch can be adapted to various system architectures, making it a versatile choice for different photovoltaic installations.

مقاومت در برابر آب و هوا

The IP66 rating and UV resistance make the VOPV isolator switch particularly suitable for outdoor installations, where it will be exposed to rain, dust, and direct sunlight. This level of protection ensures consistent performance regardless of environmental conditions.

Installation Guidelines for VOPV DC Isolator Switches

Positioning Recommendations

For optimal performance and safety, we recommend installing the VOPV DC isolator switch:

• In an accessible location for easy operation in case of emergency
• Protected from direct, prolonged exposure to extreme elements when possible
• Mounted vertically on a stable surface
• With adequate clearance around the switch for ventilation and operation

سیم کشی و پیکربندی

The VOPV DC isolator switch supports both single and double string configurations:

• 2-pole option: Suitable for single string installations
• 4-pole option: Ideal for double string setups, providing isolation for both strings simultaneously

Connection can be made using MC4 plugs with appropriate adapters or through cable glands, offering flexibility based on your specific installation requirements.
