250 KW off grid solar inverter, Integrated with MPPT chaging controller and DC/AC bi-directional inverter, support hybrid mode.
Hybrid Solar Inverter
Hybrid inverter is the connection port between grid/load and energy storage device. SI series hybrid inverter is a unique product developed by Sinexcel, with the functions of on grid inverting, off grid inverting, battery discharging control and peak load shifting, widely used for various application.
System structure: PV array, wind turbine, diesel engine or other power source, battery, hybrid inverter, AC load, grid bypass bus, widely used for isolated areas such as plateau, island, remote area and other outdoor field operations, also as energy storage system with grid power, to realize energy storage, electricity dispatch and peak load shifting.
Operation mode:
Grid tie mode: with grid or other power source (e.g: diesel), DC power from PV panel charge battery, and supply to load or grid after bi-directional inverting at the same time.
Off grid mode: Without grid power, DC from PV panel charge battery, and supply to load after bi-directional inverting.
Hybrid mode: with other power sources (e.g diesel engine), supply to load or grid, and also capable of charging battery in reverse direction with grid or diesel.
Feature:
Modularization for easy system design
DC voltage input and output adjustable
Bi-directional inverting
Battery charging management
Battery complete isolation from grid
Constant voltage and current charging mode optional
On grid, off grid and hybrid mode automatically switchover
Anti-islanding function
