This Off-Grid solar system is available in 10KVA ~ 120KVA models with DSP digital control technology, it is combined with pulse-width modulation (SVPWM), disturbance MPPT control and multi-level control technolgy to enable the stysem to track the maimum power of solar panels fast. Its secure power supply feature provides good quality power with regualted voltage and frequency to the loads, and it is featured with engergy storage and staggering power consumption as well. It is an ideal inverter for medium-sized or large-scale residential, commercial and industrial PV applications which are off the gird, such as village, farm, factory, office building and islands etc.
Features
High-speed DSP digital control
Full-bridge invertert control techonology, providing secure power supply in the event of three phase 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 entend 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
