Different Versions of Solis Inverter

Two main versions of Solis inverter for which it’s basically famous:

String Inverter:

  • The DC electricity produced in the string inverters is then transformed into AC current.
  • Solis’ string inverter needs to be kept near the fuse box and electricity meter.
  • They are usually cheaper than other types of inverters.
  • String Inverters are really good solar inverters for homes.
  • One or a maximum of two-string inverters will suffice on a solar panel located on a residential rooftop.

Hybrid Inverter:

  • It’s also known as a “smart inverter” because it smartly ensures that no energy is lost.
  • It has both on-grid and off-grid capabilities, giving you the benefit of using the solar inverter even when it gets dark.
  • A hybrid inverter supplies DC power to the battery. And it also provides power to your home’s appliances, for both on-grid and off-grid systems, in the form of AC current.
  • It can track the correct time to draw charges from the grid. And also, when the battery is fully charged, the excess amount of energy can be sent back to the grid.
  • Hybrid solar inverters can go to standby mode if any problem arises, rather than turning off completely.
  • It can also expand batteries that help lessen your troubles caused by the lower voltage battery compatibility.
Solis is famous for its innovative string technology to deliver first-class reliability, validated under the strictest international certifications. And if you are concerned about your solar panels in Australia’s extreme weather conditions, let me assure you that Solis’s inverters provide protection against harsh weather; it ensures that no environmental catastrophes can worsen the already set heating conditions of the solar inverter.
