Modular, plug-and-play energy system designed for remote and weak-grid locations. Deploy in just 2 hours — no grid connection required.
The ARCH Off-Grid Electricity System is a fully modular, mix-and-match power solution built for locations with no grid access or unreliable weak-grid connections. At its core is a 4kW solar PV + 60kW/115kWh Energy Storage System (ESS) module, forming the backbone of your independent power supply.
4kW per set — expandable to 8kW (2 sets)
High-efficiency solar panels mounted on the ESS module frame, providing clean daytime generation. Two sets can be deployed for maximum solar input in high-demand applications.
60kW power / 115kWh capacity
Industrial-grade lithium battery module providing round-the-clock energy storage. Powers your loads through the night, during cloudy periods, or when solar input is insufficient.
Ready to power in 2 hours
Pre-wired, pre-tested modular units that connect via standardised interfaces. No complex installation — just position, plug in, and start generating power. Easy to deploy and relocate as your project needs change.
Extend your system with optional modules to match your power requirements.
Backup & Extended Runtime
On-demand diesel generation for extended outages, low-sun periods, or peak load support. Integrates seamlessly with the ESS to auto-start when battery levels drop below threshold — ensuring uninterrupted power supply.
Clean Charging Infrastructure
Add electric vehicle charging capability to your off-grid site. Powered directly from the solar + battery system, enabling zero-emission transport for remote operations — perfect for mining camps and farm fleets.
Mix & Match: Choose one or both add-ons — diesel generator, EV charger, or neither. Your system is configured to your exact needs.
Position, connect, and power up in just 2 hours. No civil works, no complex wiring — truly plug-and-play.
Start with one module, add more as your power needs grow. Solar PV can scale from 4kW to 8kW across two sets.
Move your power system to a new site in hours, not weeks. Ideal for temporary projects and rotating work camps.
Fully independent power generation and storage. No grid connection, no DNSP approvals — just clean energy wherever you need it.
Optional diesel generator provides seamless backup for extended low-sun periods or peak demand — never run out of power.
ARCH handles everything — system design, delivery, installation, commissioning, and ongoing support. One point of contact.
Temporary or semi-permanent remote camps
Replace expensive diesel-only generators with a hybrid solar + battery system. Cut fuel costs, reduce emissions, and enjoy reliable 24/7 power for accommodation, lighting, and camp operations.
Rural properties with weak or no grid access
Power irrigation pumps, fencing, sheds, and homesteads from solar + battery. Add a diesel generator for drought periods when solar output is lower.
Areas with unreliable grid supply
Use the system as a hybrid backup — drawing from the grid when available, switching to solar + battery when voltage drops or outages occur. Seamless transition, zero downtime.
