We launched the newest STI series Pure Sine Wave Inverters, it covers 200VA~1000VA and has the features of high reliability, high efficiency and extensive electronic protection. At the same time, we start using the new registered brand “EPever” in inverter series products.

Product Features:
◆ Complete isolation-type inverter technology, noiseless output
◆ Adoption of advanced SPWM technology, pure sine wave output
◆ Dynamic current loop control technology to ensure inverter reliable operation
◆ 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
◆ Optional energy saving mode
◆ Extensive protections: Reverse polarity, short-circuit, overload, under/over input voltage, over-temperature, and inverter’s inner fault identification protections
◆ Wide working temperature range (industrial level: -20℃~ +50℃)
◆ Continuous operation at full power

In 2012, 20000 pcs STI500-24-220 pure sine wave inverters was applied in Solar Home System Project in Tibet, China where the altitude is about 5000m. The operation is reliability and stability and gets the praise from the users.
