It supports DC/AC coupling, offers an optional model with a built-in STS, achieves on-grid/off-grid switching time of <10ms, and delivers a maximum efficiency of 98.5%.

Key Features

  • Grid-forming inverter
  • 125% overload capacity
  • Maximum efficiency 98.5%
  • Optional built-in STS (<10ms switching)
  • Supports heterogeneous battery access
  • Three-phase independent grid-connected control

Product Description

The SP125HCPS series microgrid energy storage converters are suitable for scenarios such as small commercial and industrial facilities, island microgrids, farms, villas, and echelon utilization of batteries. The product features technologies including grid-forming inverters, 125% overload capability, isolated air ducts, hybrid diesel generator operation, heterogeneous microgrid batteries, and independent three-phase grid-connected control. It supports parallel operation of multiple units and is available in two models: with built-in STS and without STS, enabling rapid switching between grid-connected and off-grid modes.
