SPH5K-48 5.0kW Single Phase Solar off grid inverter

  • The SPH5K-48 is a high-power model within the SPH series, specifically engineered to meet the electricity demands of entire households or small commercial premises. With a rated output power of 5.0 kW and a robust surge capacity of 7500 VA, it serves as the ideal core component for driving large appliances or inductive loads.
  • This device utilizes a 48V battery voltage system, achieving a conversion efficiency of up to 91% in battery mode—a feature that effectively extends the runtime of the energy storage system. Leveraging advanced DSP control technology, it generates a 120V pure sine wave output with extremely low distortion, thereby providing a safe and secure power supply for sensitive electronic equipment.
  • In terms of PV input capabilities, the SPH5K-48 pushes boundaries further, supporting a maximum PV array power of up to 6000W and a maximum charging current of 100A. Its MPPT controller maintains high-efficiency operation across a wide voltage range of 70–280 VDC, ensuring optimal energy harvesting even in cloudy or low-light conditions. Regarding its feature set, the unit not only supports a battery wake-up function but also facilitates deep integration with lithium battery BMS systems via an RS485 interface, thereby optimizing battery lifespan. The device employs an intelligent fan-based cooling system to ensure that temperature rise remains within safe limits, even during high-power operation. Combined with an optional cloud-based monitoring system and a configurable grid-feed function, the SPH5K-48 offers a comprehensive 120V off-grid system solution for users seeking high capacity and energy independence.
