Solar Systems

High-efficiency integrated solar power system, the VSM series inverters are equipped with MPPT solar chargers that maximize the utilization of solar PV modules, thereby increasing daily power output.

The settable LCD allows users to choose between different priority modes (solar power first or utility/grid power first). VSM's advanced battery management (ABS) ensures optimal charge/discharge conditions for batteries, thereby enhancing battery cycle-life and reducing overall application costs.

VSM inverters can be paralleled up to 6 units to support power capacities up to 30kVA for large-scale applications.

Technical Features

  • Inverter efficiency up to 93.2%, prolonging battery backup time and cycle life.

  • Selectable power source as the first priority (Solar, Utility, or Uninterruptible).

  • Adjustable charging current based on different battery Ah capacities.

  • Scalable up to 30kVA by paralleling up to 6 units.

  • Optional 400Vac three-phase output.

  • Friendly compatibility with diesel generators.
