Key Features

  • Battery-Optional Operation: A game-changer for budget-conscious users, this series can power loads directly from the PV array without a connected battery, reducing initial system costs.

  • High Voltage MPPT: Supports a Maximum PV Open Circuit Voltage up to 500V (Model dependent), allowing for longer solar string configurations and reducing wiring costs.

  • Dual AC Output: Featured on most models (2012/3624/4024/6048/6248), this function provides a secondary output for non-critical loads, offering smarter energy distribution (Note: 5248 PRO model has single output).

  • Pure Sine Wave & High Efficiency: Delivers clean, stable power for sensitive electronics with a peak inverter efficiency of 93%.

  • Smart Communication: Built-in WIFI/RS485/CAN interfaces support remote monitoring and direct communication with Lithium Battery BMS for enhanced safety and performance.

  • Parallel Capability: (Check specific model support) Allows for system expansion to meet growing energy needs.

Applications

  • Flexible Off-Grid Living: Perfect for homes or cabins where battery investment might be delayed; start with just solar panels and the inverter.

  • Hybrid Systems: Ideal for areas with unstable grids, seamlessly blending Solar, Utility, and Battery power.

  • Heavy Load Management: Dual output models help manage heavy vs. essential loads automatically.
