The state promises that by 2030, the cumulative installed capacity of photovoltaic and wind power will reach more than 1.2 billion kilowatts, and has finalized the blueprint for the development of photovoltaic and wind power industries in the 14th and 15th Five-Year Plans. PV, especially household PV, has also ushered in a favorable opportunity from the central government to the local government: in 2021, there will still be national subsidies, local subsidy policies, carbon peak and carbon neutrality in the 14th Five-Year Plan.
On March 19, CHINT Power's new residential product, a new generation of residential PV inverter 10-25kW, made its debut at the "2021 Household PV Brand Conference". For a long time, CHINT Power has a significant advantage in string inverters, and its three-phase string products have been the first in sales in the North American industrial and commercial market for five consecutive years. This year, the power supply has also made another effort in household products.
Today, we will follow the analysis of Zhu Lihua, product director of CHINT Power, to unveil the mystery of CHINT's new generation of 10-25kW residential inverters!
Eradicate potential safety hazards and give you all-round protection
Because the household photovoltaic system is installed in the user's residence, its safety protection cannot be ignored. In order to ensure the safety of customers' lives and property, CHINT Power has made a lot of payments in terms of equipment safety, and carried out three steps of "safety protection": source eradication, process maintenance, and end control.
Now AFCI2.0 (DC arc detection) has been announced, and DC arc detection does not have false alarms or false negatives, ensuring the safety of the DC side. In addition, the 25kW model has professional secondary lightning protection maintenance, terminal temperature detection, optional functions of RSD rapid shutdown, explosion-proof and flame-retardant useful methods on the DC side and communication measurement.
Ensure safe power generation, and a number of maintenance functions are online
A qualified PV inverter product must have a perfect maintenance function, so as to ensure the safe and stable power output of the PV system.
Antai 10-25kW household inverter has perfect maintenance function, useful to avoid abnormal failures or accidents, IP65 and C5 protection ability, useful to ensure that the inverter can adapt to a variety of harsh environments.
It is useful to prevent derating and improve the reliability of components
Derating planning is to make the operating stress accepted by the component operation appropriately lower than the rated value of the component rules, and then reduce the failure rate and improve the reliability.
How to prevent derating of Antai 10-25kW residential inverter?
1 | Input current: The maximum current of the inverter DC single string is 13A, the hardware margin is 15A, and the MPPT parallel connection scheme is considered simultaneously to effectively cope with the application of 210 components | 2 | Full load MPPT voltage range: The MPPT voltage range of the inverter is 400V~850 V, which makes the overall PV design scheme more flexible | 3 | AC overvoltage derating: The maximum protection voltage of AC overvoltage is 480V, and the overvoltage derating function can be set according to actual needs to effectively control the output voltage | 4 | Over-temperature derating: The maximum working voltage range of the inverter is -30°C~60°C, and the temperature is 45°C without derating at full load | 5 | High altitude derating: The maximum working altitude of the inverter is 4000m, and the maximum altitude without derating is 3000m |
Intelligent monitoring, so that customers experience more comfortable
CHINT power supply simplifies complexity, RS485/WiFi/4G and other communication modes to flexibly monitor and operate and maintain, so that customers can experience more comfortably.
Only enterprises with core technology development ability and innovation promotion can continue to release new brand vitality and product competitiveness in the severe market competition environment. CHINT Power deeply excavates customer needs, continuously brings customers a more comfortable experience, provides customers with stable, reliable and trustworthy products, and helps the photovoltaic industry to develop in a healthy and orderly manner.
