Off-Grid Solar Inverter 10 kVA - 120 kVA (3:3)

Characteristics Technical Specifications Documents

● High-speed DSP digital control

● Full-bridge inverter control technology, providing secure power supply in the event of threephase 100% unbalanced loads

● Multi-string PV connected

● Inbuilt AC rectifier and MPPT control modules, configured battery parameters by operating interface, self-regulation for charging voltage and current

● Hot-swap MPPT modules for easy maintenance and power expansion

● Auto access MPP tracking states, be most probable to use PV energy in priority

● Intelligent AC and PV complementation power supply function to extend the battery life

● Using multicore control technology and auto MPP trackers, auto-start AC rectifier enable PV and AC source to supply power to the loads at the same time in the event of insufficient PV, which reduces battery discharge times and extend the battery life

● Intelligent staggering power consumption function

● Standard RS232, RS485 and optional SNMP communication port

● Multiple remote control: startup, shutdown, abnormal clearance, EPO, battery test and remote alarm port

● Staggering energy storage and power generation
