20KW 220VAC/230VAC solar inverter without battery for solar panel system

solar inverter without battery,inverter solar power,20kw solar inverter system

solar inverter without battery 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 It is widely applied to large solar power generation occasions including families Schools, public lighting, industrial and mining enterprises, frontier defense, sea islands, pasturing areas

Product Description

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 feature, 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)
