Off-Grid Solar Inverter 3 - 8 kW

Characteristics Technical Specifications Documents

● Independent MPPT control microprocessor system

● Independent inverter control microprocessor system featured with high-speed online stabilization

● Advanced SPWM technology, high-speed power MOS

● MPPT control using PWM technology enable to bear the maximum PV open-circuit voltage

● Operating mode selectable: PV priority or utility power priority

● Charging current selectable according to configured battery

● AC input with effective online synchronous stabilization technology

● Auto-tracking mains phase to ensure that inverter output voltage has same phase with utility voltage, reducing transfer time and peak surge

● No-load auto shutdown function (optional)

● Automatic frequency selection

● Auto Power-On/Off function; real-time monitoring, test and intelligent startup / shutdown by RS232 or USB interface communicating with PC; remote monitoring by optional SNMP networks
