Bangzhao Electric
1 / 3
Utilizes high-efficiency monocrystalline or polycrystalline silicon photovoltaic panel arrays to capture solar energy through Maximum Power Point Tracking (MPPT) technology, converting light energy into direct current (DC) electricity.
DC power is converted to AC via smart inverters and simultaneously stored in lithium iron phosphate (LFP) batteries. These batteries feature extended cycle life (≥5000 cycles), high safety, and wide operating temperature range (-20°C to 60°C), ensuring stable energy storage and release.
An integrated EMS (Energy Management System) continuously monitors PV generation, battery status, and load demands. It intelligently schedules “self-generation for self-consumption with surplus storage,” supports grid-connected/off-grid dual-mode switching, and ensures uninterrupted power supply during outages.
