Product Overview

This series products is a single-phase string type - the photovoltaic grid-connected inverter. The main function is to convert the DC power generated by the PV string into AC power and feed it into the power grid. 



Model
It includes the following 6 models: SI 1K-S2/SI 1.5K-S2/SI 2K-S2/SI 2.5K-S2/SI 3K-S2/SI 3.3K-S2
The corresponding powers are: 1KW, 1.5KW, 2KW, 2.5KW, 3KW and 3.3KW


 

Working Principal

◆ The DC input is generated by sunlight to the PV string to access to the inverter.
◆ To do the real-time monitoring of each string operation and track the highest power point according to the MPPT, through the input current detection circuit. 
◆ To convert the DC power into AC power through the inverter circuit and integrate it into the grid to meet the grid requirements.
