Key Features & Advantages
  • High Efficiency & Pure Power: Achieves up to 96% peak efficiency (PV to AC) and delivers pure sine wave output (230VAC), ensuring safe and optimal operation for all sensitive electronics and appliances.
  • Advanced Dual Solar Charging: Built-in dual MPPT controllers (Max 160A) allow connection of two separate PV arrays, maximizing solar energy harvest from different roof angles or panel types.
  • Flexible Power Modes: Operates with or without a battery. Features dual AC outputs (Main: 11KW, Secondary: 5.5KW) for intelligent load management and critical circuit backup.
  • Scalable System Design: Supports parallel connection of up to 6 units, enabling power expansion up to 66KW to meet growing energy demands.
  • Smart Monitoring & Communication: Built-in WiFi for remote monitoring and control. Compatible with lithium batteries via RS485 communication for optimal battery management (BMS).
  • Robust & Reliable: Rated IP21 for dust and drip protection. Wide operating temperature range (-10°C to 55°C) and a durable metal casing ensure performance in diverse environments.
  • User-Friendly Design: Clear LCD display, intuitive controls, and well-labeled connection ports (AC IN, AC OUT, PV IN, Parallel Ports) simplify installation and operation.
Application Scenarios
  • Residential: Whole-house or critical load backup power, maximizing self-consumption of solar energy, reducing electricity bills.
  • Commercial: Powering small businesses, offices, workshops, or remote telecom sites with reliable off-grid or backup power.
  • Hybrid Systems: Ideal for solar-plus-storage systems aiming for energy independence and grid resilience.
