Company Info

Growatt was founded in 2011 by a group headed by David Ding, who remains the CEO today. It wasn't long after the company was founded that Growatt started shipping inverters to Australia, focusing on the budget end of the market. The firm subsequently abandoned Australia for a few years; returning with new inverter line-up.

Aside from string, battery and central inverters, the company also produces EV chargers, monitoring and energy storage systems. Its Huizhou, China manufacturing facility is huge - covering 200,000 square meters and boasting an annual output of 3,100,000 inverters. Growatt's new manufacturing plant in Haiphong, Vietnam produces solar inverters and batteries, with plans to expand the facility to an annual production capacity of 500,000 inverters.

According to Wood Mackenzie, Growatt was the fifth biggest inverter shipper globally in 2023. 

Quantity Is One Thing. What About Quality?

While Growatt inverters have received a number of industry awards, there are some issues worth noting.

In 2021, there was a recall of 8kW Growatt inverters in Australia, affecting hundreds of units. While in the big scheme of things the impact was small when you consider how many inverters Growatt produces each year, no doubt owners of affected units weren't happy with the situation.

There have also been issues for some time around getting satisfactory support from Growatt. This post about Growatt from SQ's Anthony, a veteran installer, is quite enlightening and a little unsettling. 

Growatt Inverter Models

Growatt offer a wide range of string and battery inverters in Australia, including:

MIN Residential String Inverters

Available in capacities of 2.5kW - 10kW, the MIN range offers a maximum claimed efficiency of 98.1% and two or three MPPTs; depending on the model. These units have an operating temperature range of –25 °C - +60 °C and an ingress protection rating of IP66. In the 7kW to 10kW range, the inverter dimensions are 425 x 387 x 180 mm and the units weigh 18.2 kilograms.

MIN And MOD Storage Inverters

There's quite a selection of battery inverters in the MIN and MOD range. The MIN range offers capacities from 2.5kW - 6kW, and the MOD range from 3kW to 10kW.  These inverters  have claimed efficiencies ranging from 98.2% to 98.6% 

The single-phase MIN models are 375 x 350 x 160mm and weigh 9.1kg - 10.8kg, while the MOD line is 425 x 387x 147mm and weights range from 11.5kg to 13kg.

Note that some Growatt battery inverters are only compatible with certain Growatt batteries.

Warranty Details

Growatt inverters are backed by a standard 5 year warranty from the date of installation, and no more than 5 and half years from the date of delivery from the Growatt factory. 5 years is a pretty common warranty duration among inverters at the budget end of the pricing spectrum. But for Australian owners, there's also the option of extending this by an additional 5 years on selected models; so a total of 10 years.

Conclusion

Like any brand, there are fans and critics. Judging by the reviews below it appears many Australians who have Growatt inverters installed seem pretty happy with them. But given the hit-and-miss nature of Growatt inverter gear and what appear to be ongoing support issues, the company *isn't* currently listed on SolarQuotes' recommended inverter brands chart.
