AHS-12-SP 12kW Split-Phase Solar Battery Hybrid Controller

  • AHS-12-SP 12kW Split-Phase Solar Battery Hybrid Controller delivers a premium energy management experience for large residential properties and commercial environments with high power demands. This model boasts an impressive rated output power of 12,000 VA (12 kW) and a momentary peak power capacity of up to 24,000 VA—sufficient to simultaneously power a full suite of high-end household appliances. It supports split-phase output modes (110/220 VAC or 120/240 VAC), generating high-quality pure sine wave current that provides a grid-stable power environment for sensitive electronic equipment.
  • The AHS-12-SP represents a significant breakthrough in photovoltaic integration capabilities. It features a dual MPPT input design capable of accommodating up to 15,000 W of solar panels; with a maximum input current increased to 27A + 27A per channel, it is fully compatible with high-power PV modules. For large-scale energy storage applications, the unit offers a maximum charging current of 250A and supports parallel operation of up to six units, greatly enhancing system scalability and flexibility. Operating in battery mode, the device achieves a peak efficiency of 96.1%, ensuring minimal energy loss during the power conversion process.
  • In terms of physical specifications, the unit measures 480 × 410 × 120 mm and weighs 14.5 kg, offering an exceptionally high power density relative to other products in its class. This model integrates comprehensive safety protection mechanisms, holds an IP54 protection rating, and supports remote intelligent monitoring and maintenance via Wi-Fi.
