TSOL-M350/M400 is a high-efficiency microinverter that can be connected to a single solar panel. They are usually installed on the roof, under the panels. 1 MPPT per module, on average 10 to 30% more yield than with conventional inverter. The microinverter is very compact and lightweight, easy to install by one person , and easy to combine with other TSUN microinverters, for optimal flexibility of your PV installation, is the perfect choice for PV systems with an odd number of solar panels.


  • Individual optimization, separate dedicated MPPT for each panel.
  • Max efficiency up to 96.7%.
  • Plug and play installation.
  • Max DC voltage 60V.
  • Integrated LoM protection function.
  • Die casting design and glue filling technology.
  • Standard 12 years warranty.
