per piece


Product details

Techfine VE3024 is a 6th-generation off-grid solar inverter technology, with built-in MPPT technology.



  • Pure sine wave output.
  • Max. DC input power of 1600W (30-150VDC)
  • Higher charging and discharging power of 60A & 1600W. 
  • Compatible with solar panels and wind turbines as well.
  • 2-year warranty and can be expendable for up to 5 years.
  • Transformerless design support both Lead Acid and Li-ion batteries
  • Transformerless design & True MPPT technology ensure zero loss in solar energy production
  • A Transformer Inverter requires 2500W panels to provide the same solar output (transformerless design inverter systems are almost 99% efficient)
