High-Efficiency String PV Inverters

This document provides technical specifications for several string grid-tied PV inverters from KSG, ranging from 1kW to 3.2kW capacity. It lists specifications such as input voltage range, output voltage and frequency, maximum output power, efficiency rating, dimensions, and environmental tolerances for each model. The inverters are designed to convert DC power from photovoltaic panels into AC power that can be fed into the electric grid or used by local loads.
