Hybrid Power Supply
Product Overview:
LCX Power-YFG wind-solar hybrid power supply belongs to communication base station & off-grid no-power-area series.
It adopts full-digital DSP hybrid energy management control, integrates MPPT photovoltaic charging module and wind turbine rectifying & charging module.
It makes full use of solar and wind complementary characteristics, converts intermittent wind-solar energy into stable DC power for communication loads and energy-storage battery banks.
Modular design supports parallel expansion and redundant configuration. It can cooperate with storage battery, diesel generator or municipal power supply to form multi-energy complementary off-grid power supply system.
It effectively solves power-supply difficulties for remote sites without mains grid, reduces fuel consumption of diesel generators, and provides long-term reliable power guarantee for unattended outdoor communication equipment.
Typical Applications：
· Off-grid 4G/5G remote communication base stations in mountainous, pastoral and island areas
· Meteorology, hydrology, forest-fire-prevention, environmental monitoring outdoor terminals
· Highway, railway, pipeline along-line unattended monitoring equipment
· Border outposts, oil-gas field scattered field-site power supply
· Wind-solar-storage hybrid micro-grid system for remote no-power regions
· Supplementary power supply for weak-grid sites to reduce diesel-generator working hours
