Telecom Base Station PV Power Generation System Solution
Single Photovoltaic Power Supply System (no AC power supply)
The communication base station installs solar panels outdoors, and adds MPPT solar controllers and other equipment in the computer room. The power generated by solar energy is used by the DC load of the base station computer room, and the insufficient power is supplemented by energy storage devices.
| Number | Photovoltaic capacity | Controller capacity | Battery capacity (two days backup) | Load power (working 24 hours a day) |
| 1 | 13000W | 300A/48V | 3000Ah/48V | 3000W |
| 2 | 25000W | 500A/48V | 5000Ah/48V | 5000W |
Stacked Photovoltaic System (with AC power supply)
Install solar panels outdoors and add equipment such as MPPT solar controllers in the computer room. The power generated by solar energy is used by the DC load of the base station computer room. The insufficient power is replenished by the AC power after rectification through the switching power supply.
| Number | Photovoltaic capacity | Controller capacity | Energy saving effect |
| 1 | 2000W | 50A/48V | 10.8kwh/day |
| 2 | 4000W | 100A/48V | 21.6kwh/day |
| 3 | 6000W | 150A/48V | 32.4kwh/day |
| 4 | 8000W | 200A/48V | 43.2kwh/day |
