M19 IP67 Waterproof Connector Wire To Board 300V Multi Pin 2+20 Pin For Solar System

1. 2+20 Pin Split Design for Solar Power & Signal Isolation

• This M19 multi-pin connector features a professional 2+20 pin split layout customized for solar systems. 2 pins are used for main power transmission, while 20 high-density pins realize multi-channel signal collection and control. Physical isolation effectively eliminates electromagnetic interference of photovoltaic equipment.
• Rated at 300V low voltage, it fully matches the operating voltage of solar modules and energy storage systems. With sufficient electrical safety margin, it ensures stable continuous power output without voltage drop or overheating during long-term solar power generation.
• High-capacity integrated design replaces multiple separate connectors, greatly simplifying internal wiring of solar equipment, optimizing circuit structure and reducing overall failure rate.

2. Professional Wire To Board Integrated Structure

• Adopts standard wire-to-board connection mode, connecting external solar harness on one side and directly plugging into the equipment PCB mainboard on the other. It reduces intermediate conversion links and line loss for embedded photovoltaic equipment assembly.
• Standard M19 circular size with precise positioning tolerance supports automated mass production assembly, improving installation accuracy and production efficiency of solar equipment.
• Compact and lightweight structure saves internal installation space, perfectly suitable for photovoltaic inverters, energy storage controllers and solar data acquisition modules.
