Description
4/0 AWG Ultra-Flexible Tinned Copper Battery Cable – 1000V Silicone Wire
The 4/0 AWG Ultra-Flexible Tinned Copper Battery Cable from Geo Eco Systems provides a heavy-gauge conductor solution for solar battery banks, off-grid inverters, energy storage equipment, and compatible DC electrical systems. Designed with thousands of fine copper strands, this flexible silicone wire offers the combination of conductivity, insulation performance, and routing flexibility needed for demanding electrical projects.
Featuring a nominal 120 mm² conductor specification, this cable uses tinned copper strands protected by silicone rubber insulation. The manufacturer specifies a 1000V voltage rating and a maximum rated temperature of 200°C (392°F), making it an option for appropriately designed electrical assemblies requiring these characteristics.
Ultra-Flexible Tinned Copper Construction
Unlike conventional coarse-stranded battery cables, this 4/0 AWG wire features approximately 24,000 individual tinned copper strands, each measuring 0.08 mm in nominal diameter. This fine-stranded construction provides excellent flexibility, helping installers route large conductors through battery cabinets, inverter compartments, and other equipment spaces.
The tinned copper conductor helps resist surface oxidation while maintaining the electrical properties required for power connections. Its specified conductor resistance of no more than 0.15 ohms per kilometer at 20°C provides a documented value for evaluating resistance in properly designed electrical circuits.
High-Temperature Silicone Rubber Insulation
The 4/0 AWG silicone battery cable features RoHS-compliant silicone insulation designed to provide flexibility and thermal resistance. The insulation has an average thickness of 3.0 mm and a specified minimum thickness of 2.4 mm.
Its finished outside diameter measures approximately 21 mm, with a manufacturing tolerance of ±1.5 mm. The flexible silicone covering helps simplify routing where conventional heavy-gauge conductors may be difficult to position.
With a temperature rating of 200°C and a voltage rating of 1000V, this wire provides high insulation ratings. Actual installation requirements must still account for terminal temperature limitations, equipment specifications, circuit protection, and applicable electrical codes.
Solar Battery and Inverter Applications
This ultra-flexible 4/0 AWG cable can be considered for a variety of high-current electrical applications when its specifications meet the requirements of the complete installation.
- Solar battery bank interconnections
- Off-grid inverter DC power connections
- Lithium battery energy storage systems
- DC power distribution equipment
- Custom heavy-gauge battery cable assemblies
- Compatible industrial and renewable energy equipment
The manufacturer recommends a DC current rating of 600A at 20°C. This figure is a manufacturer recommendation rather than a universal allowable ampacity. Actual permitted current depends on conductor installation conditions, temperature, compatible terminations, protective devices, and applicable electrical standards.
Available in Red and Black
Geo Eco Systems offers this cable with red or black silicone insulation. These color options allow installers to distinguish DC conductors when following the appropriate wiring conventions.
Both colors share the same specified conductor construction, insulation material, voltage rating, and temperature rating. The cable is offered by the foot, allowing customers to select the length needed for their electrical project.
