Product Description
15kw off Grid Inverter with Charge Controller for Solar System
Introduction
The product is an intelligent inverter with built-in charge controller designed for large photovoltaic power generations. Its built-in control r can realize charge management for a battery pack by multiple solar arrays to improve charge efficiency and life of the battery pack. Thanks to the DSP control base on SPWM high-frequency carrier technology and IGBT power device, it can control the output operation parameters accurately to provide a high quality and reliable pure sine wave AC power supply for precision equipment.
Application
^ Household Appliances:Lamps ,refrigerator,TV,washing machine,electric fans, vacuum cleaner,
air conditioner, satelliate receiver, micro-wave oven, induction cooker etc.
^ Office area:Computer, printer, copier, scanner, digital camera and etc.
^ Traffic Devices:Military vehicle, police cars, medical ambulance, ships,ect
Advantages
High reliability
Frequency tracking noise filtering and low distortion in inverter output because of double-conversion design
High adaptability
A wide range of input frequency which realizes stable operation of fuel generators
High optimal performance of the battery
An intelligent battery management technology, which guarantees a longer battery life and decreases the times of battery maintenance
An advanced constant-voltage charge technology, which activates the battery to the most extent saves the charge time and guarantees a longer battery life
Overall and reliable protection
A power-on test function, which can avoid the faults because of hazards of the inverter
Efficient IGBT (insulated Gate Bipolar Transistor) Inversion technology
Good high-speed switching features
Large-voltage and large-current operating characteristics. And voltage drive of IGBT (The fifth-generation IGBT has a lower saturation voltage drop and higher operation efficiency and reliability)
