Dahua Integrated Solar Lithium Battery DH-PFM372-L45-4S14P

Description Die-Cast Aluminium Construction with IP66 Protection The battery housing uses die-cast aluminium material for durability. IP66 protection grade resists dust and water ingress. The simple structure creates a compact and light design suitable for outdoor installations. Operating voltage runs at DC12.8V with maximum charging voltage reaching DC14.6V. Power Specifications and Capacity Nominal capacity delivers 45Ah storage. Charging current operates at 9A with maximum charging current reaching 10A. Discharge current runs at 9A with maximum discharge capability of 10A. Internal resistance measures ≤80mΩ for efficient power transfer. The battery charges from solar panels during daylight hours and supplies power to cameras during nighttime or low-light conditions. This cycle supports continuous camera operation without mains electricity connection. System Integration Requirements Complete solar solutions require three main components. The battery stores power generated by solar panels. Solar panels convert sunlight into charging current. Cameras draw power from the battery for continuous operation. The battery works with integrated solar systems including DH-PFM364L-D1, DH-PFM363L-D1, and DH-PFM363L-SD1. These systems combine solar panels, batteries, and cameras into complete surveillance packages for remote locations. Installation and Mounting The compact design simplifies installation at camera sites. Lightweight construction reduces mounting requirements compared to larger battery systems. The aluminium housing handles outdoor temperature variations and weather exposure. Mounting locations should provide solar panel access for optimal charging. Battery placement near cameras minimizes cable runs and voltage drop. IP66 protection allows exposed outdoor mounting without additional weatherproof enclosures. Charging and Discharge Cycles Solar panels charge the battery during daylight. Charging voltage ranges up to DC14.6V maximum. The 9A charging current replenishes battery capacity. Full charging time depends on solar panel output and available sunlight. During camera operation, the battery discharges at up to 9A. The 45Ah capacity supports extended operation between charging cycles. Discharge continues until battery protection circuits prevent over-discharge damage. System Applications Remote locations without mains power benefit from this solar battery system. Construction sites, agricultural properties, and temporary installations use solar power for camera operation. Rural areas lacking electrical infrastructure deploy these systems for perimeter monitoring. Solar-powered cameras with cellular connectivity eliminate network cabling requirements. Combined with battery storage, the complete system operates independently of traditional utilities. This suits temporary surveillance needs and permanent installations in isolated areas. Voltage and Current Management The DC12.8V rated voltage matches standard security camera power requirements. Maximum charging current of 10A accommodates various solar panel configurations. Maximum discharge current of 10A supports camera power demands during peak operation. Internal resistance below 80mΩ minimizes power loss during charging and discharge. Efficient power transfer extends battery life and maximizes available capacity for camera operation. Weather Resistance and Durability IP66 protection guards against dust particles and water jets from any direction. The die-cast aluminium construction withstands physical impacts and environmental exposure. This protection maintains battery performance across seasons and weather conditions. Temperature tolerance supports operation in varied climates. The compact size and sealed construction prevent moisture ingress that damages electronic components. Aluminium material resists corrosion from humidity and precipitation. Power System Configuration The battery connects to cameras through standard power cables. DC12.8V output matches camera voltage requirements directly. No additional power conversion equipment is needed for matching voltage specifications. Solar panels connect to battery charging inputs. The system automatically manages charging when sunlight is available. Battery protection circuits prevent overcharging and deep discharge that reduces battery lifespan. Maintenance and Monitoring The sealed battery design requires minimal maintenance. No water topping or electrolyte checks are needed unlike traditional lead-acid batteries. Lithium chemistry provides consistent voltage throughout discharge cycles. Monitoring battery voltage indicates remaining capacity. Systems may include battery status reporting through management software. This enables remote monitoring of power system health.   Technical Specifications Model: DH-PFM372-L45-4S14P Type: Integrated Solar Lithium Battery Material: Die-cast aluminium Protection Grade: IP66 Rated Voltage: DC12.8V Nominal Capacity: 45Ah Charging Voltage: Max.
