Product Features of Three Phase Hybrid Solar Inverter

This 3 phase hybrid solar inverter is built around SiC technology and a 22kW to 50kW power range, and the 50kw 3 phase hybrid inverter model gives large PV and storage systems one platform for solar, battery, grid and generator power.

  • SiC technology: high-efficiency conversion with 98.6% max efficiency and 97.97% European/CEC efficiency.
  • 2 independent battery ports: supports a mixture of old and new batteries; 140-800V battery range for Lithium-ion, Lead-acid or Sodium-ion; up to 128kWh battery energy.
  • 150%-340% PV input power: 3 MPPTs and 40A PV input current for higher compatibility with PV panels.
  • 200-470% grid input power: 150A grid input current supplies loads and charges the battery in parallel.
  • Generator port with smart monitoring: max generator input current of 150A.
  • 150% overload: peak power of 150% for 10s, with optional AFCI function.
  • Parallel operation: up to 6 units in parallel (off-grid mode).
  • Compact and rugged: smaller size, easier installation and price-wise shipping; IP66, intelligent air cooling, -25°C to +60°C operating temperature.
  • Monitoring: LED + Bluetooth + APP, with WiFi/LAN/4G connectivity.

Commercial Applications of Three Phase Hybrid Solar Inverter

In a hybrid system, solar power supplies the load first and any excess charges the battery; further surplus is fed back to the grid. When solar generation falls short, the battery and grid supplement the supply, so this 3 phase hybrid solar inverter supports peak shaving and demand management while keeping backup power available.

Applications & Use Cases

  • Peak shaving and demand management: shift stored energy into high-demand periods to lower grid draw at commercial and industrial sites.
  • Solar self-consumption: PV serves the load first, charges the battery with the excess, and exports only the remaining surplus.
  • Grid congestion relief: helps alleviate congestion in areas with high solar penetration.
  • Virtual power plants (VPPs): supports participation in electricity market services such as VPPs.
  • Backup power for critical loads: provides seamless backup power where high supply continuity is required, with a dedicated back-up load output.
  • Generator-assisted sites: the 150A generator input lets the inverter work with a generator and ATS arrangement as shown in the system diagram.
  • Scalable capacity: up to 6 units in parallel (off-grid mode) for larger loads.
