Integrated Outdoor Solar Power UPS System 3KW/5KW 2.56KWH
CNW4850L Characterization:
1. The whole system integration includes an off-grid solar inverter module, lithium iron phosphate battery pack,
PDU, and outdoor cabinet.
2. The system is commonly used in the corner of the city, remote roads, mountains, bad environments, dust,
moisture, rain, mist-erosion, very poor power qual ity in the area.
3. The system provides a continuous pure sine wave AC power supply for outside communications/network equipment.
Internal Structure:
Key Feature:
■ Intel l igent variable-speed fan to efficiently dissipate heat and extend system lifespan.
■ It comes with double l ithium battery activation modes: mains and PV, and supports l ithium battery access.
■ Al l-round protection for solar panels includes overload and short circuit protection, under-voltage and
over-voltage protection, and reverse polarity protection.
■ With sun protection, heat insulation, roof venti lation.
■ With waterproof and the filtration dust inlet.
■ The cabinet body is designed for the IP55 protection level. The cabinet front door shutters with waterproof
design, on the back of welding outdoor cabinet.
■ Modular design is easy to maintain.
■ System configuration AC and DC lightning protection

Application And Environmental Adaptability:
1. Wide input voltage, avoids frequent switching to battery power because of large power grid voltage, reduce
battery failure probability, adapt to the power environment in poor areas.
2. The environment which require higher IP level, we use heat exchanger to effectively reduce the temperature
of box inside and improve IP protection level .
CNW4850L Series Remark:
■ For long-term storage, the electricity needs to be cycled every 6 months.
■ When loading and unloading the battery during transportation, please be careful not to drop do not stack it
over 4 layers, or place it upside down, and ensure that the front is facing up.
