Sofar Solar Inverters In Australia

The firm ran into some trouble in Australia some years ago when the Clean Energy Council delisted all Sofar inverters in early 2018 after one model failed CEC testing for compliance. Those failures were considered indicative of similar issues in other models. There was also a related nationwide recall shortly after this event. The issues were rectified with a firmware update and subsequently Sofar inverters were back on the CEC's approved list by around June that year. 

Today, Sofar's portfolio includes string inverters ranging from 1 kW to 350 kW and hybrid inverters from 3 kW to 20 kW. The company has a dizzying array of models approved by the CEC for use in Australia; but we'll just focus on a couple of lines.

KTLM-G3

Designed for residential solar, the KTLM-G3 series has a maximum efficiency up to 98.1%. The KTLM-G3 range in 7 - 10.15kW capacities has 3 MPPTs with 150% DC overload capacity. They are also compatible with 500W+ modules - not that there's many of those installed on home rooftops in Australia. 

The KTLM-G3 range has natural (convection) cooling and can operate in ambient temperatures of -30°C to +60°C, with derating above 45°C.

Inverters in KTLM-G3 7, 7.7, 8, 9, 10 and 10.5 kW capacities measure 468 × 380 × 187 mm and weigh 17.5kg - 18.5kg

According to the firm, SOFAR 8-10KTLM-G3 are its best sellers in Australia.

HYD KTL-3PH

This range are hybrid three-phase inverters available in 5, 6, 8, 10, 15 and 20 kW capacities. These dual MPPT inverters offer flexible selection and switching of multiple modes, and maximum efficiency of up to 98.2%

There's a UPS function to ensure stable operation of key loads and the AC side supports three-phase unbalanced output.

Measurements are 586.6 x 515 x 261.2 mm across this range, while weights vary between 33kg and 37kg depending on capacity; so they are a fair lump of a device weight-wise.

Warranty Information

The warranty for both hybrid and standard inverters is 10 years. An extended warranty period can be purchased to 15 or 20 years.
