Hybrid Inverter
4.5-9kW丨LFP/VRLA丨 2 MPPTs


  • On-grid and off-grid dual output, can drive air conditioning and other inductive loads, and off-grid switching time can be less than 20ms to realize uninterrupted power supply

  • Adaptable to lithium batteries, batteries and PV/AC system are isolated by high frequency transformer, which is safe and reliable

  • Bidirectional DCDC can greatly reduce switching loss and improve charging/discharging efficiency due to resonant soft-switching ZVS technology and synchronous rectification technology

  • Compatible with wired CTs and meters for anti-reverse flow to protect power grid from pollution
