Solplanet ASW20K-LT-G2 3-phase grid inverter 20 kW

The Solplanet ASW20K-LT-G2 Pro is a three-phase grid inverter with a rated power of 20 kW designed for medium and large photovoltaic installations. The device supports two MPPTs with configuration A:2; B:2, a wide MPPT operating range (150 V–1000 V), and high energy efficiency, enabling efficient energy production from PV systems containing large modules and bifacial panels.

Manufacturer Solplanet provides the ASW LT-G2 Pro series of inverters with simplicity of installation and remote monitoring in mind. Devices in this series have an IP66 protection rating for outdoor use, modular connectors (Phoenix Contact for DC and plug-in type for AC), and support communication via RS485, Wi-Fi, and LAN. The inverters meet international standards and certifications relevant for grid operation.
