1. Introduction
This manual provides essential information for the safe and efficient operation of your Luminous Solar Grid TIE Inverter 5KW/3P NXI(305) V3. A grid-tied inverter converts the constantly varying DC solar power and feeds it into the grid. It synchronizes the frequency and the output voltage to its connected grid. When solar energy increases, the inverter output increases too, injecting into the grid. Please read this manual thoroughly before installation and operation.
