Pylontech Cable Kit

Pylontech External Cable Kit for Battery to Inverter Integration

Purpose-Built Connectivity for Pylontech Energy Storage Systems

The Pylontech Cable Kit provides a complete wiring solution for connecting a Pylontech lithium battery or battery bank to an inverter charger. Engineered for 48V energy storage systems, this kit ensures reliable power delivery and stable communication between components, reducing installation complexity and potential points of failure.

Each kit includes two 4 AWG power cables (approx. 25 mm²) with a constant current rating of 100 A and a peak capacity of 120 A, making it suitable for high-demand applications. The cables are terminated with quick-connect plugs on one end and 3/8"-16 (approx. M10) stud lug terminals on the other, designed to accept heavy-duty lugs up to 4/0 AWG (approx. 95 mm²). This dual termination style supports both Pylontech's proprietary battery interface and standard inverter connections, offering flexibility during installation.

Two RJ45 communication cables are also supplied: a 3-metre cable with blue marking for linking the battery to an inverter or hub (pins 1–3: null, pins 4–8: pin-to-pin), and a 3-metre cable with silver marking for parallel connection between master batteries (pins 1–8: pin-to-pin). These data cables maintain signal integrity over distances up to 3 metres, ensuring consistent battery management system (BMS) communication.

*Note typical de-rating factors apply; maximum current capacity may be influenced by installation conditions such as ambient temperature, cable bundling, and ventilation.

Key Features

• 100 A constant current rating (120 A peak) for demanding inverter loads
• 4 AWG (approx. 25 mm²) power cables with orange positive and black negative identification
• Quick-connect and 3/8"-16 (approx. M10) lug terminals for versatile connection options
• Two 3-metre RJ45 data cables for inverter/hub and battery-to-battery communication
• Pre-configured pinouts eliminate guesswork and reduce wiring errors
• External cable length under 3 metres optimised for typical rack or wall-mount setups

Reliable Power Delivery for Off-Grid and Backup Systems

Unlike generic cable assemblies, this kit is specifically designed for Pylontech's US5000-B, US3000-C, and UP2500 battery models. Using the correct cable kit helps maintain system warranty compliance and ensures that voltage drop is minimised across the connection. The 4 AWG conductor size balances flexibility with low resistance, supporting efficient energy transfer in 48V solar battery systems.

For installers, the colour-coded power cables and labelled RJ45 leads simplify commissioning. The quick-connect ends lock securely into Pylontech battery terminals, while the lug ends provide a robust interface with most inverter DC inputs. This reduces the need for custom fabrication and speeds up deployment in residential, commercial, or mobile energy storage projects.

Compatibility and Sizing

One cable kit is required per Pylontech US5000-B battery, per three US3000-C batteries, or per two UP2500 batteries. This modular approach allows system designers to scale storage capacity while maintaining a tidy, professional installation. The external cable length of less than 3 metres is ideal for installations where the battery and inverter are in close proximity, such as in a garage, utility room, or equipment rack.

Built for Australian Conditions

With a maximum DC voltage rating of 120 V, this cable kit is suitable for 48V nominal systems commonly used in off-grid and hybrid solar setups across Australia. The robust insulation and quality connectors resist corrosion and mechanical wear, contributing to long-term reliability in varied environments.
