CNW4850L Outdoor Telecom Equipment Cabinets IP55 Outdoor Solar Power System
CNW4850L Outdoor Telecom Equipment Cabinets IP55 Outdoor Solar Power System
Product Description:
- It adopts full-digital double closed-loop control, combined with advancedSPWM technology to output pure sine waves.
- Two output modes: mains electricity bypass and inverter output; uninterrupted power supply.
- Four charging modes: PV Only, Mains Electricity Priority, PV Priority, and PV&Mains Electricity hybrid charging.
- Advanced MPPT technology with 99.9% effificiency.
- Comes with an LCD display and 3 LED indicators that can clearly indicate the status and data.
- Power saving mode, reduce no-load loss.
- Intelligent variable-speed fan to effificiently dissipate heat and extend system lifespan.
- It comes with double lithium battery activation modes: mains and PV, and supports lithium battery access.
- All-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 ventilation.
- With waterproof and the fifiltration 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 confifiguration AC and DC lightning protection.
Remark:
- Long-term storage of the battery needs to be placed in a dry, clean, dark, and well-vertilated indoor ervironment. The suitable storage temperature range is-20-35°C.
- Batteries must be stored and transported in a state close to 50%SOC.
- For long-term storage, the electricity needs to becycled every 6 months.
- When loading and unloading the battery during transportation, please be careful not to drop it, do not stack it over 4 layers,or place it upside down, and ensure that the front is facing up.
IP55 Outdoor Cabinet Characterization:
■ The whole system integration includes an off-grid solar inverter module, lithium iron phosphate battery pack, PDU, and
outdoor cabinet .
■ The system is commonly used in the corner of the city, remote roads, mountains, bad environments, dust, moisture, rain, mist-erosion, very poor power quality in the area .
■ The system provides a continuous pure sine wave AC power supply for outside communications/network equipment .
IP55 Outdoor Cabinet Environmental Adaptability:
■ 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 .
■ The environment which require higher IP level, we use heat exchanger to effectively reduce the temperature of box inside and improve IP protection level .
