SPH8.5K-48-SP 8.5KW Split-Phase Olar Off Grid Inverter

  • SPH8.5K-48-SP 8.5kW Split-Phase olar off grid inverter is a high-power, split-phase off-grid inverter developed by APsolway. Tailored specifically for 120/240V±5% power systems, it is perfectly designed to meet the high-load electricity demands of North America and related regions. Its pure sine wave output delivers power quality comparable to that of the utility grid, effectively safeguarding the safe operation of sensitive electronic equipment.
  • In terms of PV performance, the SPH8.5K-48-SP features an advanced dual-MPPT input design, supporting a maximum PV array input of 5400W + 5400W (totaling 10.8kW) with an MPPT efficiency reaching up to 99%. Its wide MPPT operating voltage range (120–450 VDC) and a maximum open-circuit voltage of 500 VDC significantly enhance the system’s energy harvesting efficiency.
  • A key highlight of this model is its support for battery-free operation, allowing loads to be powered directly by solar energy when sunlight is sufficient. Furthermore, the device features a built-in dust-proof kit designed to withstand harsh environments, and it supports remote smart monitoring via Wi-Fi or 4G connectivity. This product is fully compatible with both lithium-ion and lead-acid batteries, supporting BMS communication and automatic activation for lithium batteries.
