Safety-First, Standards-Based Installs

Our installs follow the key safety principles of AS/NZS 3000:2018 for RV solar systems; weatherproof connections, correct cable sizing, secure battery installation with adequate ventilation, and appropriate circuit protection and isolation for safe maintenance.

Tidy Workmanship You Can Trust

Neat cable routing, proper crimping, strain relief, and secure mounting, built to handle vibration and movement. Batteries are installed securely with appropriate ventilation as required for safety.

Custom Designed (No Cookie-Cutter Kits)

Every RV and travel style is different. We design a system around how you actually use power—charging sources, battery capacity, monitoring, and future expandability.

Compliance-Aware Approach

Where required, we work with qualified electricians to ensure the installation meets New Zealand requirements and relevant standards.
