● High reliability: adopt high-speed DSP control system, combine advanced SPWM technology and high-speed power MOS
● Operating mode selectable: energy storage priority or power supply priority
● No PID attenuation damage for solar panels to ensure their service life
● Flexible battert management system: auto switch three-stage charging mode shortens recharge time: wide charging current is selectable according to configured battery; flexible DOD (Depth of discharge) is settable to meet more applications
● AC input with effective online synchronous stabilizing technology
● Board MPPT input voltage range
● No-load auto shutdown function (optional)
● Settable frequency (50 Hz / 60 Hz)
● Mobile APP monitoring
● 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
