Core Technical Advantages

Our system’s superiority is rooted in its high-quality components and intelligent design. Unlike makeshift solutions, every part of this off the grid solar power system is optimized for maximum efficiency, durability, and long-term performance.

Solar Panel: The high-efficiency 15W monocrystalline panel is the primary energy harvester for this small off grid solar power system. Its 22-24% conversion rate ensures maximum energy capture, even in low-light conditions, while the 3.2mm thick hail-proof glass provides unparalleled physical resilience against environmental damage.

Battery: At the heart of this off grid DC solar power system is a robust 64Wh LiFePO4 (Lithium Iron Phosphate) battery. Renowned for its safety and longevity, this battery chemistry operates flawlessly across a wide temperature range from -20°C to 60°C and is rated for over 2000 charge cycles while retaining more than 80% of its original capacity, guaranteeing years of reliable service.

Controller: The advanced PWM controller is the intelligent brain of the setup. It not only manages power flow with high efficiency but also features a critical <50ms automatic switchover to a backup AC grid source during prolonged bad weather. This seamless transition is a key feature of our reliable solar power off grid system, ensuring zero downtime for connected devices.

Enclosure: The entire unit is housed in a rugged IP65-rated steel casing. This provides total protection against dust and water jets, while the structural integrity can withstand wind loads of up to 2400Pa, making this off-grid solar power system a truly durable solution for permanent outdoor installation.

Precision-Powered Scenarios

This versatile small off grid solar power system is designed to meet the specific power needs of a wide array of IoT and monitoring devices.

✓ Solar for 4G CCTV Camera
This system is the perfect power source for continuous surveillance. It can reliably power a typical 3W per day 4G camera for over 21 days without a single hour of sunlight, providing true zero grid dependency for security in remote perimeters, construction sites, and agricultural fields.

✓ Raspberry Pi Solar Kit
For developers and engineers, the system delivers a stable and clean 12V/4A output, making it an ideal power supply for Raspberry Pi 4 clusters or other single-board computers used for data processing, edge computing, or gateway functions in the field.

✓ DTU/RTU Solar Charger
With its RS485 readiness, this off grid DC solar power system seamlessly integrates with Data Transmission Units (DTUs) and Remote Terminal Units (RTUs). It supports custom 4G/WiFi modules for real-time remote monitoring and control of your distributed assets.

✓ Low Power Solar for Soil Moisture Sensor
Efficiently powering ultra-low-power devices like soil moisture sensors is a specialty of this compact unit. It can achieve a full 0.5-day recharge cycle even when operating in partial shade, ensuring continuous data collection for precision agriculture.

Smart Energy Management

The intelligence of our off the grid solar power system lies in its dynamic energy management, which optimizes power usage and extends operational runtime.

• Light-Direct Mode: During peak sunlight, the system intelligently routes solar energy directly to the load, achieving 100% solar utilization with zero conversion loss, maximizing efficiency.

• Hybrid Boost: In cloudy or overcast conditions, the system automatically blends solar and battery power, providing up to 30% longer runtime compared to standard systems.

• Grid Assist: For ultimate reliability, the system features a <50ms automatic switch to an AC power source during extreme weather events, ensuring connected devices never lose power.

• Visual Alerts: A simple 4-color LED indicator provides an instant, clear status of charge cycles and load conditions, allowing for easy at-a-glance system health checks.

Deployment-Ready Configuration

We understand that ease of installation is critical. That’s why this solar power off grid system arrives pre-configured for rapid deployment.

• Pre-wired aviation connectors on a 900mm cable for simple, foolproof, and weatherproof connections.

• Adjustable angle bracket allowing for optimal solar panel tilt between +15° and 60° to capture the most sun throughout the year.

• 304 stainless mounting hardware included to resist corrosion and ensure a secure, long-lasting installation.

• Easily expandable to support up to 80W of total solar input, making it a scalable off-grid solar power system capable of powering larger loads like 4G base stations.

For a resilient, efficient, and intelligent power solution that guarantees the uptime of your critical off-grid infrastructure, TecDeft’s off grid DC solar power system is the definitive choice.
