Dahua DH-PFM378-B125-CB Solar Panel – Integrated Monitoring System with PTZ Mount

The Dahua DH-PFM378-B125-CB solar panel delivers reliable off-grid power for remote surveillance installations. Combining a 125W monocrystalline panel with advanced MPPT charging technology, this integrated system maintains continuous operation where mains electricity is unavailable or impractical.

Advanced Solar Power Management

High-Efficiency Energy Conversion

Featuring monocrystalline silicon cells with 21% efficiency, this solar panel maximises energy generation even during limited sunlight hours. The integrated MPPT controller achieves 99% tracking efficiency or greater, ensuring optimal charging performance throughout varying weather conditions. Consequently, installations in areas receiving just 3.5 hours of daily solar exposure maintain reliable power supply.

Intelligent Protection Systems

Multiple safeguards protect both battery and connected equipment from electrical faults. Over-temperature, over-discharge, over-voltage and low-temperature protection prevent battery damage, whilst overload and short-circuit protection secure connected devices. Furthermore, the RS-485 communication capability enables remote monitoring when paired with compatible lithium batteries, allowing operators to track system performance without site visits.

Technical Specifications

Real-World Deployment Solutions

Agricultural Monitoring

Farms requiring surveillance across extensive acreage often lack electrical infrastructure in remote fields. Installing this solar-powered system eliminates trenching costs for power cables whilst providing year-round monitoring capability. The adjustable panel angles accommodate seasonal sun position changes, maintaining consistent charging efficiency. Additionally, the aluminium alloy frame withstands agricultural environments including exposure to fertilisers and pesticides.

Construction Site Security

Temporary building sites benefit from portable surveillance without relying on generators or temporary electrical supplies. Mounting the system on poles between 80mm and 150mm diameter provides flexibility for various site configurations. Because the unit resists sustained winds up to 117 km/h, it remains operational during adverse weather that might otherwise compromise security coverage.

Wildlife Reserve Observation

Conservation areas implementing remote camera monitoring face unique power challenges. This solar solution operates at altitudes below 3,000 metres and functions in temperatures from -20°C to +60°C, suiting diverse geographical locations. Meanwhile, the IP65 rating protects electronics from dust and moisture in humid forest or arid desert environments.

Border and Perimeter Surveillance

Extended boundary monitoring requires distributed camera placement along lengthy perimeters. Rather than extending mains power across kilometres, individual solar-powered units provide autonomous operation at strategic positions. The included PTZ camera ceiling mount bracket (PFB301C) and adapter (PFA111) simplify installation of compatible pan-tilt-zoom cameras for comprehensive area coverage.

Compatible Equipment

This system works with the PFM372-L45-4S14P integrated solar lithium battery (sold separately). Compatible PTZ cameras include the DH-SD6C3432XB-HNR-AGQPV, DH-SD49425DB-HNY-GQ-LA, and DH-SD49425DB-HNY-GQ-EAU models, all offering 4MP resolution with Starlight IR capability.

Frequently Asked Questions

Q1: Does the DH-PFM378-B125-CB include a battery?

No, this model is sold without a lithium battery. The compatible PFM372-L45-4S14P integrated solar lithium battery must be purchased separately to complete the power system.

Q2: How much sunlight does the system need to operate effectively?

The system requires areas with daily exposure to solar radiation for more than 3.5 hours. This allows the 125W monocrystalline panel to generate sufficient power for continuous camera operation and battery charging.

Q3: Can the solar panel angle be adjusted after installation?

Yes. The panel adjusts horizontally through 360° and vertically at preset angles of 10°, 20°, 30°, 40° or 50°. This flexibility optimises sun exposure based on geographical location and seasonal variations.

Q4: What pole sizes are compatible with this mounting system?

The pole mount accommodates poles ranging from 80mm to 150mm in diameter, providing compatibility with standard infrastructure including lighting columns, fence posts and purpose-built surveillance poles.

Q5: How does RS-485 communication benefit system management?

RS-485 connectivity enables remote monitoring of battery status, charging performance and power consumption when using compatible lithium batteries. Operators can diagnose issues and plan maintenance without travelling to remote installation sites.
