1.2KW – 1.28KWH Wall-Mounted PV All-In-One Energy Storage System

Model: YJC-HES-L-A-1.2kVA/1.28kWh

Model: YJC-HES-L-A-1.2kVA/1.28kWh

Key Features

  • 4-IN-1 INTEGRATED DESIGN: Inverter, MPPT solar charger, battery charger and battery all integrated into one enclosure – far fewer parts, far less wiring, much faster install.
  • EFFORTLESS, WALL-MOUNTED PLUG-AND-PLAY: Sleek wall-mounted format and pre-wired layout remove the need for extra brackets or complex wiring – ideal for balcony and small-home installs.
  • SEAMLESS SOLAR-TO-HOME & GRID BACKUP: Solar charges the battery; the built-in PCS/DC-AC inverter supplies household loads or hands off to the grid automatically when needed – simple energy flow, reliable backup.
  • COMPACT, COST-EFFECTIVE HOME SOLUTION: Small footprint and integrated components lower both material and labour costs – a practical, affordable choice for modern households.
  • REAL-TIME MONITORING & INTUITIVE DISPLAY: High-contrast LCD screen monitoring shows voltage, current, frequency and system status for easy oversight and control.
  • RELIABLE THERMAL CONTROL & ROBUST HOUSING: Intelligent cooling fan, sturdy metal enclosure and BMS protections keep temperatures stable and protect the system in daily use – backed by common industry warranties.
