Description of this Pad mounted transformer integrated inverter HC2500KTS grid connect power inverter module

Hua Cheng's product, built-in transformer, is a grid-connected inverter with a capacity of about 2.5MW.
High Efficient Power Generation
● I-type three-level technology, the maximum efficiency of the inverter up to 99.0%, the European efficiency up to 98.7%
● 1.1 times load operating at 45℃, full load operating at 55℃, using the fifth generation high-temperature and high-efficiency IGBT
● Dormancy function, single module operating at light load and whole unit operating at heavy load,independent operating between each module, effectively extending the life of the device
● Anti-PID technology, reducing PV modules degradation and the loss of power generation
● Optimizing inverter and transformer connection, reducing system loss better

High Reliability
● Multiple dust proof, strict thermal design, moisture-proof, anti-corrosion, salt-spray proof, adapting to harsh natural environment
● Integrated fans featured with online failure detection function and fan temperature control function
● DSP + CPLD full-digital control, multiple and multilevel protections of overcurrent, overvoltage and overtemperture for software and hardware
● Strengthened electrical insulation design for high altitude and high pollution level, allowable maximum altitude up to 4500 m
● CQC, ZVRT, Top-Runner certification approved

Intelligent &Friendly
● 7-inch LCD display screen, supporting fault alarm, query and download function
● Grid friendly, supporting zero voltage and low voltage ride through
● Adjustable reactive power, power factor from 0.8 leading to 0.8 lagging adjustable

Lower Cost
● 1500 V voltage grade, reducing the current of DC and AC sides, cutting down distribution cost and the overall system cost
● Integrated “inverter” with “transformer”, shortening construction period
● Unified maintenance for inverter and boost transformer, worry-free for customers
● Integrated SVG function, fully responding to grid dispatching, reducing initial investment
About system cleaning (once every 1 year (depending on the amount of dust used in the environment)):
Check the board and components for cleaning; check the heat sink temperature and dust, if necessary, the dust of the use environment
Module for dust cleaning
Clean or replace the air filter
Specific steps and maintenance intervals for maintenance projects:
Power circuit (checked half a year after the first commissioning, every half to one year thereafter):
Check if the cable connection is loose and tighten it again according to the torque required by the connection in the manual;
Check the cable for damage, especially if the skin that is in contact with the metal surface has a cut mark;
Check if the green strap of the terminal block is off.
Terminal, cable connection (every 1 year):
Check if the control terminal screws are loose and tighten with a screwdriver.
Check the main circuit terminals for poor contact
Is there any trace of overheating at the screw?
Cooling fan maintenance and replacement (every 1 year)
Check the fan blades for cracks;
Observe whether there is abnormal vibration when the fan is running
If the fan has abnormal conditions, it should be replaced in time
