On Charge exists for people who want their electrical systems to just work — properly engineered, intelligently integrated, and built to handle real-world use. We design and implement advanced power solutions across marine, off-grid, mobile, and custom applications, combining technical depth with practical, hands-on experience.

From concept through to commissioning, On Charge specialises in complex electrical ecosystems. That includes energy storage, power conversion, charging systems, solar integration, alternator upgrades, distribution architecture, monitoring platforms, and intelligent automation. Whether it’s a performance boat, expedition vehicle, caravan, site office, or a completely custom project, our focus is the same: efficient systems that are reliable, scalable, and future-ready.

System Design & Engineering

We develop complete electrical architectures tailored to the application — balancing performance, safety, and serviceability. Every design considers real operating conditions, load profiles, redundancy, and long-term expansion.

Integration & Implementation

On Charge works with industry-leading hardware and emerging technologies to deliver cohesive systems rather than disconnected parts. CAN-bus networks, remote monitoring, smart switching, and hybrid charging strategies are all part of the toolkit.

Power Storage & Conversion

Lithium battery banks, inverter/charger systems, DC-DC charging, solar regulation, alternator control, and shore/generator integration — designed to operate seamlessly together.

Custom Solutions

Not every problem has an off-the-shelf answer. We regularly design bespoke components, mounting systems, and monitoring interfaces to solve unique challenges and improve usability.

Technical Consulting

For builders, installers, and end users who need guidance, we provide clear, experience-driven advice grounded in compliance standards and real-world troubleshooting.

We believe good electrical design is equal parts engineering and practicality. That means clean layouts, clear data visibility, and systems that can be maintained without guesswork. We approach every project with a focus on efficiency, safety, and long-term reliability — because the best system is the one you don’t have to think about once it’s running.

Our Approach

* Practical engineering backed by deep technical knowledge

* Solutions built for harsh environments and demanding use

* Forward-thinking integration of new technologies

* Transparent collaboration from design through deployment

On Charge isn’t just about power — it’s about confidence. When everything is wired, configured, and optimised correctly, you spend less time troubleshooting and more time doing what the system was built for.

Power, engineered properly.
