APS6500 Pro-48 6.5kW Single Phase Off-Grid Inverter

  • APS6500 Pro-48 6.5kW Single-Phase Off-Grid Inverter is a "Professional Edition" single-phase off-grid inverter that builds upon the standard version by significantly enhancing connectivity flexibility and system integration capabilities. While its core power performance remains identical to the standard model—boasting a rated capacity of 6.5kW and a momentary peak power of 13kVA—the "Pro" series introduces a suite of advanced, industrial-grade features.
  • The most distinctive characteristic of this model is its support for "Dual AC Inputs" and "Dual AC Outputs." This functionality enables the system to connect simultaneously to both the utility grid and a generator, intelligently switching the power source for the load based on pre-configured priorities. Furthermore, it supports Meter/CT connectivity and automatic transfer switch (ATS) control for generators, thereby vastly elevating the level of automation in energy management.
  • In terms of hardware configuration, the APS6500 Pro-48 features the same robust built-in 120A MPPT charge controller, supporting a maximum PV open-circuit voltage of 520V and a solar input capacity of 9000W. This ensures exceptionally high charging efficiency, even under challenging lighting conditions. The device employs DSP control and dual-loop technology to deliver a stable, pure sine wave output, achieving an exceptionally high power density relative to other products in its power class. In addition to supporting lithium battery activation and offering a comprehensive array of interfaces—including RS232, USB, and RS485—it provides real-time cloud-based monitoring services via built-in Wi-Fi. With its superior hardware-software integration capabilities and a 2-year warranty commitment, the APS6500 Pro-48 stands as a premier choice for constructing high-end off-grid microgrid systems.
