Product Description
8KW --40KW Solar Power System Inverter with Charge Controller for Industrial
Product overview
Product is an integrated intelligent inverter with built-in charge controller system designed for large photovoltaic power
Its built-in controller can realize charge management for a battery pack by multiple solar arrays to improve charge efficiency and life of the battery pack
Thanks to its full digital vector control technology based on real-time processing by DSP, MCU and DDC, it has perfect protection functions and high reliability
Its mains supply preferred mode.and battery preferred mode are all settable, thus making it easy to meet the different application needs of users It has an LCD
Widely applied to large solar power generation occasions including families
Schools, public lighting, industrial and mining enterprises, frontier defense, sea islands, pasturing areas
Main features:
High reliability
Frequency tracking noise filtering and low distortion in inverter output because of double-conversion design
High adaptability
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
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 feature. large-voltage and large-current operating characteristics. and voltage drive of IGBT (fifth-generation IGBT has a lower saturation voltage drop and higher operation efficiency and reliability)
