Product Features & Core Advantages
1. Exclusive Original Matching for Growatt, Zero Compatibility Hidden Danger
This 4P male straight network port cable is tailor-made according to the interface protocol and pin definition of all Growatt energy storage inverters and supporting battery cabinets, realizing 99% matching of power circuit and communication circuit. The straight tube network port plug-and-play design eliminates the need for intermediate adapters or transfer wiring, completely avoiding system faults such as poor contact, communication disconnection, inverter failure and battery charging and discharging abnormality caused by mismatched non-original wiring harnesses. It can perfectly transmit DC charging and discharging power and real-time monitoring communication signals synchronously, ensuring the whole energy storage system runs stably for a long time without abnormal alarm.
2. Dual Functions of Power Transmission & Signal Communication, Simplify On-Site Wiring
Different from ordinary single-function PV power cables or separate communication network cables on the market, this integrated cable integrates power transmission and data communication transmission in one wire harness. During on-site installation and construction, installers only need to lay one cable to complete both power connection and signal data transmission, which greatly reduces the number of wiring harnesses laid in equipment cabinets, simplifies wiring layout, shortens construction cycle by more than 40%, and effectively reduces labor costs and construction error probability of PV energy storage projects. Real-time data such as battery voltage, inverter operating power, charging and discharging state can be stably uploaded to the monitoring platform through this cable without additional communication wiring.
3. Ultra-Low Energy Loss & High Transmission Efficiency, Reduce Long-Term Operating Costs
The cable adopts multi-strand high-purity tinned copper conductor with extremely low internal resistance, which greatly reduces heat generation and electric energy loss during high-load charging and discharging cycle of energy storage system. Compared with ordinary low-purity copper and aluminum-clad copper wiring harnesses, the DC power transmission loss of this product is reduced by more than 42%. For large-scale commercial and industrial energy storage power stations with long-term continuous operation, it can effectively improve the photovoltaic self-consumption rate and grid-connected power generation efficiency, saving a large amount of electricity loss costs for enterprise customers every year. The optimized double-layer insulation structure effectively reduces the temperature rise of the cable under full load, avoiding accelerated aging and performance attenuation caused by overheating.
4. Extreme Environmental Adaptability & Ultra-Long Service Life
The outer sheath and inner insulation layer both adopt electron-beam cross-linked low-smoke zero-halogen XLPO material, with outstanding comprehensive weather resistance. It can resist long-term outdoor ultraviolet radiation, rainwater erosion, wind and sand impact, high-temperature oxidation and low-temperature embrittlement, and can maintain stable electrical performance and intact structural appearance in harsh environments such as coastal high humidity salt fog, desert high temperature drought and northern cold low temperature. The IP65 fully sealed connector effectively prevents water vapor and dust from invading the contact pin, avoiding oxidation rust and poor contact faults. After multiple rounds of professional long-term aging test and mechanical fatigue test, the product will not crack, harden or lose efficacy within 25 years of service life, synchronizing with the service cycle of photovoltaic power stations and greatly reducing later maintenance and wiring harness replacement costs for customers.
5. Multi-Layer Safety Protection & Simple Plug-and-Play Installation
The product is equipped with all-round safety protection mechanisms including high-voltage insulation protection, overload overcurrent protection, overheat protection, short-circuit protection and flame retardant fire prevention. When encountering abnormal working conditions such as circuit overload and internal short circuit, the cable insulation layer will not burn and spread flame, and will only produce low-smoke non-toxic gas, effectively reducing the fire spread risk of photovoltaic energy storage systems. The integrated injection molding process of connector and cable eliminates the hidden danger of wire falling off caused by traditional separate crimping wiring. The straight network port direct connection design does not require professional crimping tools, welding equipment or complex wiring operation; installers only need to align the connector and plug in until a locking click sound is heard, and gently pull back to confirm the connection is firm, realizing fast and safe on-site installation.
