Off-grid DC/AC inverter CNW4850L-3KW

all-in-onesolarsine wave

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. Feature: 1. It adopts full-digital double closed-loop control, combined with advanced SPWM technology to output pure sine waves. 2. Two output modes: mains electricity bypass and inverter output; uninterrupted power supply. 3. Four charging modes: PV Only, Mains Electricity Priority, PV Priority, and PV&Mains Electricity hybrid charging. 4. Advanced MPPT technology with 99.9% efficiency. 5. Power saving mode, reduce no-load loss. 6. Intelligent variable-speed fan to efficiently dissipate heat and extend system lifespan. 7. It comes with double lithium battery activation modes: mains and PV, and supports lead-acid battery and lithium battery access. 8. All-round protection for solar panels includes overload and short circuit protection, under-voltage and over-voltage protection, and reverse polarity protection. 9. With sun protection, heat insulation, roof ventilation 10. With waterproof and the filtration dust inlet 11. 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. 12. Modular design is easy to maintain 13. System configuration AC and DC lightning protection
