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.
Up to IP67 international protection grade. Equipped with multi-layer closed-loop sealing and high-elasticity weather-resistant rubber ring, it provides full waterproof and dustproof performance against rain immersion, sand accumulation and condensation in outdoor environments.
Optimized for outdoor solar scenarios, it resists sunlight exposure, rain, snow and frost, effectively solving common faults such as short circuit, poor contact and signal failure caused by dampness and dust.
UV-resistant and temperature-resistant sealing components maintain stable protective performance under long-term outdoor temperature alternation, ensuring year-round reliable operation of solar systems.
4. Weather-Resistant & Durable Industrial Grade Material
The high-toughness housing features excellent UV resistance, temperature resistance and impact resistance, avoiding deformation, embrittlement and fading under long-term outdoor extreme weather erosion.
High-precision internal pins ensure low impedance and stable conductivity. The power circuit supports stable load operation, and the signal circuit ensures accurate collection of solar power generation and temperature data.
Qualified 300V insulation performance prevents electric leakage and static interference, providing reliable electrical safety protection for photovoltaic power generation systems.
5. Dedicated Solar System Application
Specially designed for solar photovoltaic systems, widely applied in small solar panels, photovoltaic energy storage controllers, solar tracking devices and household photovoltaic power generation equipment.
Ideal connector for solar electrical devices requiring PCB integrated installation, multi-channel signal acquisition, stable 300V power supply and IP67 outdoor waterproof performance.
