Solplanet ASW3K-LT-G2 Pro String Inverter 3 kW Three-phase 2 MPPT
The ASW3K-LT-G2 Pro is a three-phase string inverter rated 3 kW from Solplanet, AISWEI's PV brand. It accepts up to 4500 Wp of array on 2 MPP trackers, with 1100 V maximum DC voltage and a 150-1000 V MPPT window, leaving headroom even with long strings.
Peak efficiency reaches 98.4 %. The enclosure is IP66, cooling is by natural convection and the operating range spans -25 to +60 °C, so the unit mounts outdoors with no special measures.
Wi-Fi and LAN come as standard, together with RS485 for the export meter; 4G is optional. Monitoring and setup go through the Solplanet Cloud app, including export control and feed-in power limiting.
