Hybrid Energy Telecom Power Core with 30kW PV Solar Power and 16kW Rectifier Power
1. Introduction of Hybrid Energy Telecom Power Core
The ET48500-H7E413 is an embedded power system designed to supply -48VDC power to communication equipment, its maximum output current is 500A.
It is configured with 30kW solar modules, which convert photovoltaic energy into a stable 48VDC voltage. The solar module has MPPT function, which can detect the power generation voltage of the solar panel, and track the voltage and current value to achieve the maximum power input of the module to maximize the use of solar energy.
It is also configured with 16kW rectifier modules, which convert 380VAC grid power into a stable 48VDC voltage. The rectifier module can supply high quality power to DC type communication equipment, also can charge batteries as energy backup.

4. System Working Principles
1) AC Power Supply
AC power inputs into rectifier modules through the AC distribution unit, and rectifier modules convert AC power into -48VDC power, then feeds power to multiple loads through the DC power distribution unit.
2) Photovoltaic Power Supply
The system introduces green solar energy. The PV modules convert solar energy into -48VDC power and directly send it to the DC power distribution unit. When there is sufficient sun light, the photovoltaic energy will be used as the first priority energy to feed power to loads and charge batteries, realizing energy saving and emission reduction.
3) Battery Charging & Discharging
When the AC power supply is normal, the rectifier modules not only supply power to the DC loads, but also provide charging current to the batteries. During AC power outage, the rectifier modules stop working, and the batteries supply power to the DC loads. After the AC power supply is recovered, the rectifier modules start to supply power to the DC loads, also charge the batteries to replenish the consumed power.
4) Intelligent Monitoring and Management
As the "brain" of the telecom power system, the monitoring module monitors the operating status of various components of the power system in real time and performs corresponding intelligent control. If there is any abnormality, the monitoring module reports alarm signals in time, to ensure the safety and stability of power supply.
