The SPH8.5K-48-SP 8.5kW Split-Phase solar off-grid inverter is perfectly suited for the split-phase power needs of regions like North America. This model boasts a 5.5kW (5500VA) rated output power and a peak instantaneous power of up to 8.0kVA, providing robust power support for high-power loads in homes and small to medium-sized commercial spaces. Its pure sine wave output is not only stable but also effectively protects sensitive equipment such as air conditioners and microwave ovens from damage.
In terms of photovoltaic energy conversion, this device excels. It incorporates a high-efficiency MPPT charge controller, supporting a maximum PV array power of 6600W and a maximum MPPT efficiency of up to 99%. A key feature of the SPH5.5K-48-SP is its **support for battery-free operation, meaning that in areas with ample sunlight, the system can directly power the load without connecting batteries, significantly enhancing the system's application flexibility.
Furthermore, it supports 48V battery systems** and is fully compatible with both lithium and lead-acid batteries, featuring lithium battery wake-up functionality and enabling deep communication with the battery BMS via an RS485 interface. To withstand harsh installation environments, the device incorporates dustproof components with an IP43 protection rating and supports WiFi/4G remote intelligent monitoring. This model offers a 2-year manufacturer's warranty, making it an ideal choice for users seeking energy self-sufficiency.
