Overview
The Livoltek GT3 4–25kW D1 series is a versatile three-phase grid-tied solar inverter family designed to bridge the gap between residential and small commercial rooftop installations. Featuring dual Maximum Power Point Trackers (MPPTs) with a wide voltage range of 140–1,000V and up to 16A input per string, the GT3 D1 adapts effortlessly to varying PV array configurations and high-wattage module technologies.
Optimised Practicality
A standout shadow-optimisation management system ensures maximum energy production even when panels are partially shaded by nearby structures, chimneys, or vegetation — a critical advantage for urban rooftop deployments. The inverter supports 150% DC/AC oversizing alongside 110% AC overloading, enabling project designers to extract peak performance from every available roof area.
Unmatched Efficiency
With an ultra-low 160V start-up voltage, the GT3 D1 begins generating power earlier in the morning and later in the evening, extending daily operational hours and boosting overall yield. An optional AFCI module provides proactive fire protection against DC arc faults, while smart app-based monitoring enables remote performance tracking and diagnostics. IP65-rated and built for outdoor installation, the GT3 D1 combines plug-and-play simplicity with commercial-grade reliability — all backed by RS485, Wi-Fi, Bluetooth, and DRM communication interfaces.
