South American Smart Pole Project: Reducing Long-Term Maintenance Costs with a Pure DC Power Architecture

In many parts of South America, the utility grid is unstable; brief power outages and voltage fluctuations are commonplace. For smart pole projects, this creates a recurring issue: every time the grid fluctuates, PoE switches and cameras drop offline and reboot, triggering numerous false alarms and necessitating repeated on-site troubleshooting visits.

Traditional architectures rely on AC transfer switches to toggle between grid power and battery backup, a process that inherently involves a delay. Even a lag of just a few hundred milliseconds is enough to cause PoE devices to reboot. In other words, the system failure isn't caused by the grid itself, but by the switching action.

Our approach connects grid power, solar PV, and batteries in parallel on a single DC bus—eliminating the need for switching in favor of seamless continuity. The moment grid power is interrupted, the battery instantly takes over the load, ensuring the equipment experiences no disruption.

Eliminating the inverter offers another advantage. In parts of South America, high summer temperatures can cause cabinet interiors to overheat; inverters are major heat generators and among the components most prone to failure. By removing this component through a pure DC architecture, we lower both internal cabinet temperatures and failure rates.

Regarding maintenance, the control box utilizes modular DIN-rail wiring; if a module fails, it can be swapped out via simple plug-and-play replacement. This eliminates the need for specialized electronics engineers, allowing local electricians to handle the task.

In terms of connectivity, we support open standards such as Modbus, MQTT, and RS485. Power status, battery levels, and environmental data feed directly into your own systems, ensuring you retain full control over your data. We do not engage in end-user projects, nor do we compete in the software-based value layer.

In the South American market, simplicity, stability, and power-loss resilience represent the ultimate competitive edge. By handling complex power switching and backup logic at the hardware level, we empower local IoT platform providers and system integrators to deliver high-quality smart pole projects while minimizing long-term maintenance costs.
