The SB175 Energy Storage Inverter DC Connection Cable is a high-current, high-stability DC special connection cable developed for large-scale energy storage systems, photovoltaic inverters, off-grid energy storage power stations, and industrial backup power systems. Centering on the high-power DC power transmission demand of SB175 interface energy storage inverters, this cable adopts industrial-grade high-current design, which can stably bear 175A rated current, and is specially used for the DC connection between energy storage battery packs and inverters, DC power input of off-grid inverters, and power docking of large-capacity energy storage equipment. It is a core component to ensure the efficient and safe operation of energy storage inverter systems.

In terms of electrical performance, the SB175 DC connection cable is designed with ultra-low resistance power transmission standards. The wire core is made of super-large gauge high-purity oxygen-free copper stranded wire, which has higher conductivity and lower resistivity than ordinary tinned copper wires. The multi-strand dense stranded structure makes the wire core uniform and stable, which can disperse high current, avoid local overheating of the line during high-power DC transmission, and ensure that the cable temperature rise is controlled within a safe range under long-term 175A high-current working conditions. The product has a large current overload margin, which can withstand instantaneous impact current during inverter startup, load switching and battery charge-discharge conversion, and will not cause line failure or power fluctuation.

The cable insulation and sheath layer adopts double-layer protection structure of high-temperature resistant cross-linked polyethylene and flame-retardant silicone rubber. The inner insulation layer ensures excellent electrical insulation performance and isolates DC high-voltage current to prevent leakage and short circuit. The outer sheath has super high temperature resistance, cold resistance, pressure resistance and aging resistance, with a working temperature range of -45°C to 110°C, adapting to the high-temperature heat dissipation environment of inverter equipment and the complex temperature changes of indoor and outdoor energy storage equipment rooms. The material has passed UL94 V0 grade flame retardant certification, which can automatically extinguish fire in case of line short circuit and spark, avoiding the spread of fire and ensuring the safety of energy storage equipment and power distribution rooms.

The matched SB175 professional energy storage connector is the core guarantee of product performance. The connector is made of high-strength industrial engineering plastic shell and thick pure copper silver-plated terminals. Silver-plated terminals further reduce contact resistance, solve the problem of heat generation at the connector during long-term high-current operation, and ensure stable power transmission. The connector has a built-in mechanical self-locking system and anti-vibration structure, which can maintain tight connection for a long time in the working environment of equipment vibration and fan operation, and will not loose or disconnect. The waterproof and dustproof sealing design reaches IP54 protection level, which can prevent dust, moisture and small particles from entering the interface, and avoid poor contact and corrosion of terminals in long-term operation.

The product is widely used in off-grid photovoltaic energy storage systems, household commercial energy storage inverter equipment, industrial energy storage power stations, communication base station backup energy storage systems, and wind-solar complementary power generation systems. It is mainly responsible for the DC power transmission from energy storage battery packs to inverters, converting DC power stored in batteries into AC power through inverters for load power supply. The stable low-loss transmission performance of the cable effectively reduces the power loss of the energy storage system in the DC transmission link, improves the overall power generation and power supply efficiency of the energy storage system, and reduces the operating cost of the equipment.

In terms of reliability and safety, each SB175 energy storage inverter DC connection cable undergoes strict factory full-performance testing, including long-term high-current aging test, high-voltage insulation test, mechanical vibration test, and environmental aging test. The product has stable performance, no heating, no voltage drop and no power attenuation during long-term high-load operation. The standardized interface design is compatible with all mainstream SB175 interface inverters and energy storage battery packs on the market, with strong versatility. The anti-reversal and color-coded design effectively avoids wiring errors, improves the safety of equipment installation and operation, and is a high-reliability special cable for high-power energy storage inverter systems.
