Surveillance trailers are vital in remote monitoring applications, offering reliability and efficiency. The 3-Panel Surveillance Trailer's wiring diagram provides insight into its power distribution, energy storage, and operational circuitry. Let’s break it down to understand its components and functionality.

Key Components

1. Solar Panels (PV1, PV2, PV3):

   • Each panel is rated at 435W.
   • Connections are established using MC4 connectors to streamline installation and ensure a secure connection.

2. Charge Controller (MPPT):

   • The Victron MPPT 150/60-TR manages energy flow from the solar panels to the battery bank, ensuring optimal charging and preventing overcharge.

3. Battery System:

   • Six 150Ah batteries form the storage system, providing reliable energy for night-time operations or periods with limited sunlight.
   • The system is protected by various breakers (QF2, QF3, QF4) rated at 63A, 50A, and 32A respectively, ensuring safe operation under different loads.

4. Cerbo GX and Battery Relay:

   • The Cerbo GX serves as the control interface, monitoring system performance and enabling remote management.
   • Battery relays (e.g., BR1-BR5) protect the system and facilitate efficient switching.

5. Inverter:

   • Converts stored DC power into AC power to supply components like the winch junction box or external AC loads.

6. Additional Safety Features:

   • A shunt is incorporated for precise current measurement, critical for monitoring energy flow.
   • Junction boxes isolate specific connections, simplifying maintenance.

Power Flow Explained

1. Solar to Batteries:

   • Solar panels capture sunlight and convert it into DC electricity.
   • The charge controller directs this power into the battery bank, ensuring it operates within safe limits.

2. Batteries to Devices:

   • Stored energy is routed through the inverter to power AC devices or directly used as DC output for system components.

3. Integration with External Sources:

   • The system accommodates external inputs like an AC generator or mains supply, enhancing flexibility during prolonged low sunlight.

Applications and Benefits

• Remote Surveillance:

  • The trailer supports monitoring in areas without grid access, powered by renewable energy.

• Reliability:

  • With a robust storage system and advanced charge control, the trailer ensures consistent operation in challenging conditions.

• Scalability:

  • Modular design allows for upgrades or adjustments based on specific use cases.

Conclusion

The 3-Panel Surveillance Trailer is a sophisticated integration of renewable energy technology and surveillance needs. Understanding its wiring diagram provides valuable insights into its design and operational efficiency. Such systems pave the way for sustainable and reliable surveillance solutions in remote and off-grid environments.
