Thanks for purchasing our company’s inverter of STI series. The product is a sine wave power frequency inverter which can convert 24V DC to 220V AC 50Hz based on full digital and intelligent design. It features high reliability, high efficiency, concise outline, small volume, full protection functions, easy installation and operation. The inverter can be applied in many fields especially for solar photovoltaic power system.
Complete isolation-type inverter technology, noiseless sine AC voltage of output
Adoption of advanced SPWM technology, pure sine wave output
Dynamic current loop control technology to ensure inverter reliable operation Saving mode for selection
Wide DC input voltage range
Excellent EMC design
Low output harmonic distortion(THD≤3%)
LED indicators for input voltage range, load power range, normal output & failure state
Input polarities conversed, load short-circuit, overload, under/over input voltage and over-temperature protections and alarms, inverter’s inner fault protections
Fitted for many kinds of AC loads such as household appliances, electric tools and industrial devices Wide working temperature range (industrial level)
