Latronic Sunpower: Australian-made grid-connect and stand-alone inverters

Latronic Sunpower is a Queensland, Australia-based inverter manufacturer that operates globally. The company has been in business for over 27 years. The company makes inverters for residential, commercial and industrial applications. The company has a strong reputation in Australia and many of its products are also available overseas.

Latronic Sunpower: Product range

Although Latronics started out as a specialist in off-grid inverter applications, the company has since branched out and now manufactures a range of inverters for different applications, as well as other renewable energy conversion devices.


Latronics inverters for residential, grid-connected homes

Latronics’ PV Edge inverters are designed for grid-connected homes. PV Edge inverters utilise cutting-edge microprocessor algorithms to ensure smooth, reliable power conversion. Additionally, their ability to accept low voltage inputs means easier system design, greater levels of electrical safety and better performance in conditions where shade may be an issue.

Latronics Grid Connected Battery Backup System

Systems that use PV Edge inverters can also be designed or retrofitted to include a battery backup system, which would assist in energy management and reducing power bills in addition to ensuring access to power, even in the event of a blackout. With estimated 2013 payback periods of 6-7 years, Latronics’ battery backup system is one of the most affordable on the market in Australia. It also boasts greater ease of installation, configuration and use than other battery backups available in Australia.

There are 2 models in the PV Edge series: The PVE 1200, and the PVE 2500.

The PVE 1200 and PVE 2500 allow panels to be wired in parallel sets of short strings. By separating the panels into smaller ‘strings’ than are ordinarily found in conventional PV systems, the PV Edge inverters offer an advantage in locations where shading might sometimes be an issue–e.g. next to a chimney or under a tree branch. In a conventional inverter system with longer strings, shading of even just 1 of the panels would significantly bring down the power output of the entire string. With the PVE 1200 and 2500, having multiple parallel strings means less susceptibility to the effects of partial shading while balancing volts and amps across the system.

These two unique grid inverters are 48V and 96V based and have been designed from the outset to work with batteries (by changing a simple DIP switch). Latronics Grid Connect and Off Grid inverters run on compatible voltages, making it possible to easily marry their grid and off grid inverters to form a grid connected/battery back up system that is charged from the very same panels that are usually used for exporting power to the mains grid.

Latronics off-grid inverters for remote power systems

Latronics is one of the oldest players in the Australia’s off-grid solar industry. The LS series feature a number of 12 volt (V), 24V, and 48V models ranging from 500W up to 7kW, as well as 36V, 72V, 96V & 120V units.

Other Latronics products

In addition to its inverter products, Latronics also offers a number of complementary devices and solutions, including outdoor enclosures, a turbine controller (for integrating wind and water turbines into grid-connect systems), energy meters, maximum power point trackers (MPPT), AC transfer switches (for grid/battery hybrid systems), battery chargers and a suite of solutions for marine and mobile applications. The company also builds made-to-order inverters for industrial and custom energy applications.

Latronics: Points of difference

-Latronics is wholly Australian-owned and operated. Inverters are hand-assembled by highly skilled and trained staff at the company’s plant in Caloundra, Queensland. Being Australia-based also means rapid, local support from the original manufacturer of the hardware.

-Latronics is an environmentally-minded and conscientious manufacturer: Latronics’ operations are carbon neutral thanks to an 80kW on-site solar array, and almost all of the components in its products are recyclable.

  1. My solar system was use with China inverter euro sharp have been broken i bought new pv edge 1200 inverter ,to connected in to solar panels 1.5 kw but I’m worry the input volts only 103 volts for this inverter my system total 320 volts 8 panels so what can I do please explain to me thanks

    1. Hi Le Van,

      We’re not really technical experts here (we are a brokerage & comparison service) so we would have to advise that you get in touch with Latronic Sunpower directly.

  2. We have inherited a pv edge system in our new house
    Are you able to carry out a service on it?

    1. Hi Andy,

      The above informational article is about Latronics, but we (Solar Choice) are in no way affiliated with them or their products. Please get in touch with them directly for any maintenance or warranty questions:

      Good luck with the system!
