Product Features & Core Advantages
This Growatt 16P solder-type tinned female connector is optimized and upgraded for the pain points of easy oxidation, difficult field wiring, poor waterproof performance and insufficient vibration resistance of traditional new energy connectors, with multiple core advantages suitable for Growatt equipment supporting scenarios.
2.1 Professional Tin-plated Terminal Design with Superior Conductivity & Anti-oxidation Performance
Different from ordinary untreated terminals, this product adopts full tin-plated process for all 16 pin terminals. The high-purity copper substrate ensures ultra-low contact resistance and high current transmission efficiency. The surface tin-plated layer can effectively isolate air, moisture and salt fog, prevent terminal oxidation, rust and poor contact. Compared with gold-plated terminals, tin-plated treatment has higher cost performance while meeting industrial use standards, avoiding signal attenuation and circuit failure caused by terminal oxidation in long-term outdoor humid environment. It is especially suitable for long-term unattended operation of photovoltaic power stations and energy storage equipment, greatly extending the service life of wiring harness connection parts.
2.2 Solder-Type Wiring Structure for Flexible & Efficient On-Site Assembly
The 16P female socket adopts pure wire-soldering termination design, eliminating the need for special crimping tools and crimp terminals. Field construction personnel only need a conventional electric soldering iron to complete wire stripping and soldering wiring, which greatly reduces the threshold of on-site installation and maintenance. The terminal is designed with a large welding groove, which is convenient for tin filling and wire fixing, effectively avoiding virtual welding, cold welding and wire falling off. This design is very suitable for on-site transformation, equipment maintenance and small-batch engineering wiring of Growatt photovoltaic and energy storage projects, solving the problem of inflexible wiring of traditional crimp-type connectors and improving engineering construction efficiency.
2.3 Full Set of Waterproof Accessories to Achieve IP67 High-Level Protection
Each product is equipped with original matching lock nut, waterproof cable gland and high-elasticity silicone waterproof gasket, forming a complete three-layer waterproof sealing system. The silicone gasket realizes surface sealing between male and female connectors to prevent rainwater and dust from entering the interface gap. The adjustable waterproof cable gland tightly wraps the outer skin of the cable through internal rubber compression, realizing deep sealing of the cable inlet. The matching lock nut locks and fixes the cable gland to prevent loosening caused by vibration and external force pulling. After standard assembly and locking, the whole connector reaches IP67 waterproof and dustproof level, which can resist temporary water immersion, rain washing and outdoor dust accumulation, and fully adapt to open-air photovoltaic power stations and outdoor energy storage equipment working environments.
2.4 High-Strength Flame-Retardant Housing with Excellent Environmental Adaptability
The connector shell is made of glass fiber reinforced PA66 engineering plastic, with UL94-V0 highest flame retardant grade, which can effectively prevent flame spread and improve equipment operation safety. The material has excellent UV resistance, high and low temperature resistance and chemical corrosion resistance. It will not age, brittle or deform after long-term exposure to outdoor strong sunlight, high temperature in summer and low temperature in winter. It can resist the erosion of rainwater, dew and coastal salt fog, and maintain stable structural and electrical performance in various harsh industrial and new energy working environments, reducing equipment failure rate caused by connector damage.
2.5 Thread Anti-Loosening Locking & Strain Relief Structure for Stable Connection
Equipped with threaded locking structure and integrated cable strain relief function, the lock nut can firmly fix the connector and cable gland on the equipment interface. In the working environment of equipment operation, mechanical vibration and cable dragging, it can effectively avoid interface loosening, disconnection and signal interruption. The strain relief structure transfers the external pulling force of the cable to the gland shell, completely protecting the internal solder joints from tensile damage, avoiding solder joint cracking and open circuit failure caused by long-term cable pulling, and ensuring long-term stable power and signal transmission of Growatt equipment.
2.6 Dedicated Matching for Growatt Equipment with High Compatibility
This 16P female socket is developed and produced according to the interface parameters and wiring standards of Growatt photovoltaic inverters and energy storage systems. The pin spacing, interface size and electrical parameters are fully matched with supporting male connectors and equipment interfaces, with zero assembly error.

Frequently Asked Questions (FAQ)
Q1: What is the advantage of tin-plated terminals compared with gold-plated terminals? Is the conductivity affected?
A: The tin-plated process of this product is optimized for new energy equipment scenarios. It has excellent anti-oxidation and anti-corrosion ability, fully meets the conductivity requirements of signal and low-power transmission, and has higher cost performance than gold-plated terminals. It will not cause signal attenuation and poor conductivity in long-term outdoor use, which is completely suitable for Growatt photovoltaic and energy storage equipment matching needs.
Q2: Does this connector support waterproof use alone? What are the assembly requirements for IP67 effect?
A: The IP67 waterproof performance is realized under complete standard assembly. It is necessary to install the waterproof gasket correctly, tighten the waterproof cable gland to fit the cable tightly, and lock the nut completely. At the same time, it needs to be used with the matching male connector. Single female socket assembly cannot achieve full waterproof effect. Standard assembly and locking are the key to ensure waterproof performance.
Q3: What kind of cables are suitable for this 16P connector?
A: This connector supports cables with outer diameter of 5mm-11mm, which is compatible with most conventional photovoltaic signal cables, energy storage equipment control cables and industrial multi-core cables. Too thick or too thin cables will affect the sealing effect of the waterproof gland, so it is recommended to select cables within the matching size range for wiring.
Q4: Is this solder-type connector suitable for mass production assembly?
A: The solder-type structure is more suitable for on-site installation, equipment maintenance, project transformation and small-batch customized wiring, with low operation threshold and no need for professional equipment. For large-scale mass production needs, we can provide customized crimp-type connector solutions according to customer requirements.
Q5: What is the maximum load current of the connector?
A: The rated continuous current of each pin is 8A at normal temperature. When all 16 pins work with full load simultaneously, it is recommended to properly derate the current according to the ambient temperature to avoid overheating of the connector and ensure long-term safe operation.
Q6: Can this product be used for PCB board welding?
A: This is a professional wire-soldering female socket, used for cable wire welding and on-site wiring, not applicable for PCB board plug-in welding. If you need PCB-mounted 16P connectors, please contact our sales team for alternative models.
Q7: What is the service life of the waterproof gasket? Is it replaceable?
A: The silicone waterproof gasket has high temperature resistance and anti-aging performance, with a service life of more than 5 years in conventional outdoor environments. The gasket is detachable and replaceable. We can provide independent waterproof gasket accessories for later replacement and maintenance.
Q8: Can you provide customized services for pin definition and length?
A: Yes. We support personalized customization such as pin function definition, terminal length and housing color. We can provide one-stop customized solutions according to customers' Growatt equipment transformation and special project needs.
