ASW 3-20K-LT-G2 Pro Series

Redefined versatility for powerful systems

The ASW 3-20K-LT-G2 Pro series bundles the latest innovations and upgrades in a new inverter benchmark for large-scale decentralized residential, commercial, and industrial PV systems. Because of their larger wafer-based PV modules, the ASW 3-20K-LT-G2 Pro series inverters are perfectly compatible with a huge variety of other high-capacity PV modules.

The ASW 3-20K-LT-G2 Pro inverters feature a sleek design that is IP66-rated, making them weatherproof and extremely durable. These units have two independent MPP trackers that allow for a possible 150% oversizing of the PV array, giving you maximum flexibility and efficiency. Looking for an inverter that can power an energy-hungry system? The ASW 3-20K-LT-G2 Pro inverters feature a maximum input current of 32A per string making them a fantastic choice for any high-demand installation.

Key Features


The ASW 3-20K-LT-G2 Pro series was designed in accordance with international quality and safety standards and is a robust family of extremely reliable solar inverters. The IP66 certification rating also means these inverters will maintain their reliability in a wide range of environmental conditions. From a purely technical angle, the DC reverse polarity protection, AC sensitive residual current monitoring, and built-in surge protection functions ensure reliable and safe long-term operation.


Our ASW 3-20K-LT-G2 Pro solar inverters are designed for power. A maximum DC input of 32A and a wide MPP voltage range ensure highly optimised energy performance for bi-facial and large-area PV modules.​ These dynamic solar inverters also allow for up to 150% oversizing of the attached PV array, making them perfect for residential rooftop solar installations that vary greatly in their design, scale, and purpose.

Installation & Monitoring

The ASW 3-20K-LT-G2 Pro series is designed to be installed quickly and easily with standard tools and the Phoenix Contact DC connectors make these inverters compatible with a wide range of solar panels.  Optional Plug & Play and 4G dongles connect them to the internet and allow up to five to be monitored by Solplanet’s user-friendly mobile application. Users can view real-time solar installation data, configure their inverters, and receive system alerts, right in the palm of their hand.
