Get a QuoteAdvanced DC Collection
Getting power from solar panels to the inverter sounds simple — but at a utility scale it involves thousands of cables, trenches, combiner boxes and field connections. We’ve simplified that. Our above-ground Power Lead Assembly trunk system runs a single, streamlined cable from string to inverter — no trenching, no combiner boxes in the field, no crimping on site.
Less labour. Fewer mistakes. Lower total cost.
Eco-Certified Cables
Every building, solar farm, rail network and mine site runs on cable. We supply the complete range — from everyday low voltage wiring through to high voltage transmission cables — manufactured to Australian, New Zealand and IEC/EN standards and engineered for local heat, UV exposure and harsh operating conditions.
With a focus on lower-impact materials, environmental product transparency and Best Environmental Practice PVC principles, our cable solutions support more sustainable construction, infrastructure and energy outcomes across Australia and New Zealand.
Smart Monitoring
For projects using a traditional DC collection approach, our combiner boxes bring multiple solar strings together in one compact, protected enclosure. Built for Australian and New Zealand conditions with 5,000 hours of UV protection testing for confidence in harsh sun exposure.
Inside, an integrated busbar solution minimizes electrical faults. Built-in surge protection and short-circuit protection come as standard, with optional string-level monitoring to track current, voltage, temperature and protection status in real time.
