Lead-Acid Battery 48VDC 50hz Output Frequency Solar Energy System for Telecom Base Station

Power plant or substation power for controlling, protection and automatic device, emergency lighting, communications, steam turbine DC oil pump and so on independent DC systems. It can provide reliable power supply in the case of a power failure completely in plant or substation. The traditional DC systems connect battery pack and run with float charging mode. The new DC system run with silicon controlled rectifying power supply for battery.

Key Features:

1.Adopt advanced MCU microprocessor control technology.
2.Advanced MPPT Technology,High converting efficiency higher than 97% for minimizing energy loss.
3.Reversed current protection at night, over voltage and reverse polarity protection.
4.Capable of selecting different charging mode for various types of batteries.
5.Protection degree:IP55.
6.Industy-leading power density compact size and high reliability.
7.Doorframe designed with waterproof structure, posted on the seal and equipped with waterproof lock on the door double insulation design.
8.Cabine adopt quality galvanized sheet or aluminum coated steel sheet as material, surface coating anti-UV power.
9.Suitable for outdoor installation.
