APS6500-48 6.5kW Single Phase Off-Grid Inverter

  • APS6500-48 6.5kW Single-Phase Off-Grid Inverter features a rated output power of 6.5kW and a peak surge capacity of up to 13kVA, enabling it to reliably drive highly inductive loads such as air conditioners, large refrigerators, and power tools. Utilizing a pure sine wave output, it supports 208/220/230/240V voltage systems, ensuring high-quality and compatible power delivery. Designed as a 48V system solution, it achieves a peak efficiency of 93% in battery mode, effectively minimizing energy losses during the conversion process.
  • In terms of solar energy utilization, the APS6500-48 delivers exceptional performance. It features a built-in 120A MPPT solar charge controller, supporting a maximum PV input power of 9000W. Its wide MPPT operating voltage range (60–450V) and a maximum input current of up to 28A allow it to be compatible with the majority of high-power solar panels currently available on the market. This model offers full compatibility with both lithium-ion and lead-acid batteries, featuring a lithium battery activation function and the capability to communicate with the battery's BMS via RS485. Furthermore, the device supports dual AC outputs and grid-tie functionality (Feed-in to Grid); combined with its built-in Wi-Fi monitoring module, users can achieve intelligent, round-the-clock energy management.
