Inverter is the device that convert the direct current(DC) produced by the solar panels to alternating current(AC) that your home or office can use.

The main types of inverters include solar micro-inverters, string inverters and central inverters.

Micro-inverters, which is also known as module inverters are most commonly used for individual solar power systems to extract the maximum amount of power from each solar system. These inverters are highly reliable and often include up to 10 years warranty, however add a significant cost to the solar power system.

String inverters are commonly used in grid-tied systems where solar panels are wired together in series. These inverters are designed to be wired to a series of 8 to 15 solar panels and are currently the most widely used inverters. As a safety precaution, they are designed to shut down in the event that the utility grid goes down. 

Central inverters are a type of string inverter that are used in larger scale solar systems. Cost is higher for these inverters however they are easier to install and have higher efficiency.

Inverters can come with different ratings including continuous, half hour and surge. They outline the amount of power that you can expect to use continuously without the inverter overheating, the rating for if an appliance is used occasionally, and finally a high surge to allow the inverter to hold a high rating for a few seconds for an appliance to start.


The SolarEdge DC-AC PV inverter is specifically designed to work with the SolarEdge power optimizers. Because MPPT and voltage management are handled separately for each module by the power optimizer, the inverter is only responsible for DC to AC inversion. Consequently, it is a less complicated, more cost effective, more reliable solar inverter with a standard 12 year warranty, extendable to 20 or 25 years. The fixed string voltage ensures operation at the highest efficiency at all times (>97% weighted efficiency) independent of string length and temperature. In addition to its functionality as a DC-optimized inverter, the SolarEdge inverter also manages battery and system energy as part of the StorEdge system.


Founded in Austria in 1945, they have over 65 years experience producing innovative and intelligent power storage solutions. Originally a manufacturer of battery chargers, transformers and welding equipment, they’ve spent the last 20 years developing and manufacturing solar inverters and monitoring equipment, including solar battery chargers. Fronius inverters have become a benchmark in the field, with the Galvo and Symo inverters receiving the 2013 Plus X Award for High Quality, Functionality and Ecology. The Galvo inverter was also named the best product of the year for 2013. Earlier awards include an Austrian prize for innovation for the Sunrise solar inverter in 1997, and the Solarix standalone sine-wave inverter in 1991. Their IG inverter range won the Frost & Sullivan Best Practices Award in 2008, and is only just being phased out after 15 years in the field.


Solis is a Spanish name derived from the Latin sol solis, literally meaning “SUN”. Solis Australasia are very proud to be delivering the very latest in solar inverter technology from Solis Technologies in the form of the new Solis range of inverters. The Solis inverter product range has the benefit of more than 20 years of technical development and improvement resulting from the experience and determination of the Solis engineers to produce the very best product available. They have strived to combine the very best in efficiency with the robust and reliable attributes that are demanded in the Australian market. Reliability is foremost in the design and production of the Solis inverter
