PRE RELEASE. Unlike many opinionated reviews, the Solar Review Inverter Assessment Criteria compares the Growatt TL3-S against the industries best known specifications.  The result, an inverter review with no room for discretionary bias and the transparency you desire.  

.Make and model:  Growatt TL3-S.

Variants:  3.0 | 4.0 | 5.0 | 6.0 kW.

  Battery compatibility, cooling.

  Internet connectivity, Installer remote access.

GREATER THAN 3.3 IS A VERY GOOD SCORE. The following content for the Growatt TL3-S should be used as a guide only. Individual circumstances and compatibilities should always be taken into account when selecting the right inverter for any given installation. The below Growatt TL3-S content has been built using the Solar Review Inverter Assessment Criteria 2.0 and above based on available product specifications at the time of writing. 

Design.

Design is what defines a particular solar inverters ability to meet end-user expectation from modern appeal, future integrations and versatile installation locations.

TL3-S - Performance
  • 97.1% European efficiency.
  • Temperature range of -25°C (13°F).
  • Temperature range of +60°C (140°F).
  • Temperature derating 45°C (113°F).
  • Weighs 21.2kg (46.7lbs).
  • Noise emission of 25 dB (A).

Guarantee.

Manufacturer guarantees are interesting when selecting an inverter technology. More commonly is a complimentary extension to base guarantee options in recent years. As guarantee obligations can often be shielded by installer incompetence, should a manufacturer define an adequately trained installer network with a complimentary warranty extension (added end-user benefit), such guarantee has been considered as a base warranty more likely of adhering manufacturer installation specifications.

Important: A manufacturers obligations under guarantee will be obsolete if the inverter is not installed to manufacturer specifications. Use an authorised installer.

  • 5-year parts warranty.
  • 5-year service warranty.
  • No authorised installer network.

Software.

In a modern world, software is how you interact with your self generated power supply. More than just a monitoring portal, inverter software is evolving to become the entire energy management protocol as the new standard.

TL3-S - Software
  • Growatt Monitoring Software.
  • iOS & Android app.
  • Alerts & fault diagnosis.

Affordability.

All well and good having the greatest technology, but what if that technology is simply out of reach for most? Adversely, the cheapest product may lack essential technology requirements expected by many end-users. Put price into perspective. Affordability is where price and technology come together to help determine value.
