About Growatt Solar Inverters

Growatt produces a range of transformerless (TL) solar inverters and high-frequency transformer inverters. Currently, Sungold TL, Growatt MTL, Growatt HF, Growatt UE lines are available in Australia.

Sungold TL seriesStandard Transformerless Inverters


Sungold 1500TL (~1.5kW AC output)

Sungold 2000TL (~2.0kW AC output)

Sungold 3000TL (~2.8kW AC output)

Sungold 4600TL (~4.6kW AC output)

Sungold 5000TL (~5kW AC output)

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.

Technical Specifications

Growatt MTL series: Dual Maximum Power Point Tracking (MPPT)


Growatt 3600MTL (~3.6kW AC Output)

Growatt 4200MTL (~4.2kW AC Output)

Growatt 5000MTL (~4.6kW – 5.0kW AC Output)

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.

Technical Specifications




 Growatt HF series: High-frequency transformers


Growatt 2000HF (~2.0KW AC output)

Growatt 25000HF (~2.5kW)

Growatt 3000HF (~3.0kW)

Growatt HF series inverters use quiet, high-frequency transformers, can accept inputs from two separate solar panel strings in parallel, and are MPPT capable.


Technical Specifications



Growatt UE series: Transformerless Dual MPPT inverters for larger systems


Growatt 10000UE (~10kW AC output, dual input MPPT, up to 2 parallel strings each)

Growatt 12000UE (~12.25kW, dual input MPPT, up to 2 parallel strings each)

Growatt 18000UE (~18kW, dual input MPPT, up to 3 parallel strings each)

Growatt 20000UE (~20kW, dual input MPPT, up to 3 parallel strings each)

Growatt UE solar inverters are mainly for use in larger-scale and commercial solar PV projects. Please note: Growatt UE series inverters are currently pending SAA and CEC approval.
