Growatt 5000TL Inverter
‘But I was told to buy a SMA as they are the best’?
The German magazine Photon that reviews all Solar inverters and panels and is the reference 'bible' in the industry, put the top selling SMA Sunny Boy German made Inverter in Australia only 12th, equal by the way, with the chinese made Growatt inverters. Those higher on the list are either not sold here at the moment or are for much larger solar installations than would be found in a house.
Anyway, you must tread your own path, but as they say "Just because it's repeated a lot, doesn't make it true".
Growatt is one of the most prolific solar inverter brands in Australia, with a reputation for affordability. The company manufactures grid-connect inverters for a range of residential and commercial solar power system sizes. Founded in 2010, Growatt has recently founded its Australian subsidiary, Growatt Australia Pty Ltd; the company’s Australian office is in Melbourne.
About Growatt Solar Inverters
Growatt produces a range of transformerless (TL) solar inverters and high-frequency transformer inverters. Currently, Sungold TL, Growatt MTL and Growatt HF lines are available in Australia.
Growatt MTL inverters are capable of taking power inputs from 2 different parallel strings of solar panels. Each of these inputs are Maximum Power Point Tracking (MPPT) capable, meaning higher overall efficiency and greater solar system energy yield over time.
Growatt’s 5000TL inverter has attained a ‘sehr gut’ (‘very good’–96%) at average solar irradiation conditions, and ‘sehr gut +’ (96.8%) rating for high solar irradiation conditions from Photon Magazine, a widely-respected resource on solar power system components, subjecting solar panels and inverters to rigorous testing.
