APS12000-48 1.2kW Single Phase Off-Grid Inverter

  • The APS12000-48 stands as the flagship model in the APS series, engineered to deliver exceptional power support for large-scale off-grid systems. Boasting an impressive rated output power of 12 kW—with a peak power capacity reaching 24 kVA—it ranks among the most powerful units currently available in the series. Utilizing advanced DSP control and dual-loop technology, it generates a pure sine wave output, thereby providing a power environment as stable as that of the utility grid for sensitive and precision equipment. Its peak efficiency in battery mode reaches 94%, significantly optimizing energy utilization.
  • This model achieves a significant breakthrough in PV integration capabilities; via its dual MPPT charge controllers, it supports the connection of up to 15,000 W of solar panels, making it ideally suited for constructing large-scale off-grid power stations. The APS12000-48 also features a large 5-inch interactive display and supports dual AC outputs, allowing users to flexibly prioritize power distribution between primary and secondary loads. Furthermore, the device not only includes a lithium battery activation function but also supports battery-free operation, greatly enhancing overall system flexibility.
  • In terms of physical specifications, the unit measures 480 × 410 × 120 mm and weighs 14.5 kg, maintaining an excellent power density relative to other products in its power class. Combined with built-in Wi-Fi monitoring, grid-tie feedback technology, and an IP43 protection rating, the APS12000-48 offers a premier solution for users seeking high-capacity, highly reliable green energy systems.
