Description of this Off grid solar inverter 120kVA power inverter module
 
This Off-Grid solar system is available in 10 kVA ~ 120 kVA power inverter module with DSP digital control technology, it is combined with pulse-width modulation (SVPWM), disturbance MPPT control and multi-level control technology to enable the system to track the maximum power of solar panels fast. Its secure power supply feature provides good quality power with regulated voltage and frequency to the loads, and it is featured with energy 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 grid, such as village, farm, factory, office building and islands etc.
Features
● 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
2. Inverter operation sequence
1) Start the inverter operation sequence:
(1) Check if the inverter wiring is correct, all switches should be in the off state;
(2) Check if the DC 220V power supply is normal. After confirming the normal condition, make the mains input open in the “closed” state, and the inverter ship switch is in the “closed” state (because the mains priority is given, the “mains” indicator light is on, AC The output should have 220VAC output. When the mains is cut off, the system will automatically switch to the inverter output state, the “inverter” indicator will be on, and the AC output will be normal).
(3) Check whether the various meters, indicators and fans are working properly;
(4) When the load is turned on, it can operate normally.
2) Turn off the inverter operation sequence:
(1) cutting off the AC output circuit;
(2) cut off the mains input;
(3) Cut off the 0 and 1 switches;
(4) Cut off the DC input circuit.
