Application field:
CND48200 solar system (hereinafter referred as solar system) is a solar power system that can be directly used outdoors.
Working Principle:
Through the solar module, the solar cell array transforms the solar energy into -48V DC power, which is then gathered into the DC distribution; at the same time, the AC power enters into the rectifier module and is rectified and transformed into -48V DC power which is then gathered into the DC distribution. The output of the solar module and the rectifier module is gathered together and then provided for the communication equipment in multiple channels.
1.Under normal circumstances, the power system operates in parallel floating charge(FC) state, that is, the rectifier module, solar module, load, and battery work in parallel; the solar module and rectifier module not only supply power to the communication equipment, but also provide FC current for the battery.
2. Under normal circumstances, the solar energy and the AC mains supply power normally, and the charging current for the system output load and battery is provided by the solar module. If the output power of solar module cannot meet all the loads, the rectifier module will supplement power to maintain the normal operation of the communication equipment.
3. When the output of AC mains is off, the rectifier module stop working, and the solar energy provides power normally. The charging current for the system output load and battery is provided by the solar module. If the output power of solar module cannot meet all the loads, the battery will supplement power to maintain the normal operation of the communication equipment.
4. When the output mains power is cut off, the rectifier module stop working, and the solar module cannot provide power normally. The system output load is powered by the battery to maintain the normal operation of communication equipment. When the battery discharges for a period of time and meets the conditions to start the DG, the monitor unit sends a signal to start the DG. When the DG works normally, it can provide AC input power for the rectifier module, and the rectifier module will supply power to the communications equipment again, and charge the battery to supplement the consumed power. When the DG reaches the conditions to stop, the monitor unit sends out stop signal, the DG stops working.
The monitor unit manages the functions of the solar power distribution, AC mains power distribution, DC power distribution, and DG in a centralized monitoring manner, and at the same time receives the operation information of the rectifier module and solar module through the CAN communication mode and conducts corresponding control. The monitor unit also has monitoring functions such as battery management, LLVD protection, battery protection, signal acquisition and alarms, and can carry out background communications. The monitor unit can also be connected to a local computer in RS232 mode.
