Background

▪ Base stations have been a large electricity consumer since its 24/7 operation, resulting in high electricity costs that require more effective cost-reduction measures;

▪ The expansion of 5G infrastructure is dramatically increasing the number of base stations and leading to a sharp increase in power demand;

▪ The smaller coverage of 5G requires a station density 3-4 times that of 4G and increases total energy consumption over 9-fold, resulting in soaring costs for operators;

▪ Driven by the "dual carbon" goals, operators must urgently cut base station energy use and increase green electricity adoption through measuress like local energy trading, green electricity certificate purchases, and photovoltaic plants self-construction;

▪ The simplified network sites expand, facing a lack of backup power and potential external power failures;

▪ The demand of base station power upgrade increases, while many solar-only and hybrid solar-storage systems currently underutilize both PV generation and energy storage capacity.

 Introduction

▪ The all-in one Hybrid Power Supply Solution achieves triple guarantees through photovoltaic power generation (solar), energy storage batteries (storage), and grid power collaboration (backup), realizing "power generation - energy storage - power consumption - backup power supply.

▪ Detailed system configuration is determined by site-specific conditions: solar resource, load power, electricity rates, investment objectives, solar panels, MPPT modules, DC/DC modules, AC/DC modules, and battery capacity.

 Principles

▪ Under sufficient photovoltaic conditions, the DC/DC module prioritizes solar power for base station DC loads during all periods (peak, off-peak, flat, or valley). When solar power is insufficient, the system supplements with energy storage batteries or mains power according to electricity pricing periods.

▪ The energy storage battery mainly realizes peak shaving and valley filling for the base station through the charging and discharging function, saving energy and reducing costs. The working logic is as follows:

- During the Peak periods, the Energy Storage Hybrid System powers the load;

- During the Average periods, the grid powers the load;

- During the Valley periods, the grid powers both the load the energy storage battery at the same time;

▪ During cloudy or rainy days or when there is a power outage, the energy storage battery can also serve as a backup power source for base stations, providing emergency power supply. In addition to meeting daily energy storage and discharge needs, it retains some capacity for backup battery purposes.
