1.1 Product overview
Thanks to the full-digital intelligent control technology and voltage-current double closed-loop control
algorithm adopted, IU Series pure sine wave inverter (high-frequency) has a fast dynamic response, high
conversion efficiency, low harmonic component and stable operation. With idle mode, normal mode and
energy saving mode optional, the IU Series can maximize battery energy saving based on application
scenarios and requirements;
Key components with high power density and long service life provide this IU Series with continuous
long-time and full-power output. And comprehensive electronic protections keep the entire system safer
and more stable; IU series is applicable to various off-grid systems that need to convert DC into AC, such
as RV power supply system, on-board system, monitoring system, emergency lighting system, household
power supply system, small-scale on-site power supply and occasions with high requirements for power quality.
