Since some manufacturers released 210mm silicon wafers, the industry has never stopped discussing silicon wafers, batteries, accessory changes, and component sizes.

　　As large power investment companies list "high-power modules" in the bidding process, the photovoltaic industry has become more and more recognized for ultra-high-power modules. Some manufacturers generally choose to be compatible with the 210-size when building new production capacity to ensure that production equipment can be compared Adapt to market demand for a long time. However, it is undeniable that many people's impression of 210 components is still at the level of "large size and high power", and they do not really understand the essence of 210 products.

　　Mass production of 210 silicon wafers means that an open, inclusive, and future-oriented new track platform is officially launched, including all products including silicon wafers, batteries, components, glass, inverters, and its technological innovation and development process will not slow down but only accelerate.

　　Many people equate 210 with high power and high current. But in fact, the design of the 210 module is very flexible. There are 400W, 500W and other conventional size modules using three-slice, non-destructive cutting technology, and 550W, 600W, 670W and other large-size ultra-high power products. It is reported that the maximum short-circuit current of three-slice modules is below 13A, and mainstream products of all inverter companies can be adapted, which are very popular in distributed scenarios; even products with half-chip technology and a maximum short-circuit current of 18.5A, the inverter can also handle it easily.

　　It needs to be pointed out that 600W+ modules have gone beyond the conventional thinking framework. It is necessary to think from the perspective of the system. Through low voltage and high current, the power of the module is increased while increasing the power of the string, and finally the cost of electricity per kilowatt-hour is reduced.

　　Regarding the question that the ultra-high power module "high current may cause hot spots" and other issues, in fact, the actual hot spot temperature of the module has little relationship with the current, which is mainly related to the number of batteries connected in parallel with the bypass diode. The more batteries connected in series, the greater the biased leakage current, the higher the temperature of the blocked battery, and the greater the risk of hot spots.

　　For power systems and electrical equipment, the photovoltaic system 1500V system voltage and current less than 20A are very simple requirements. Photovoltaic power generation users can decide whether to use 4mm2 or 6mm2 cables according to the requirements of environmental temperature rise, and reduce the system cost on the premise of ensuring efficient power generation.

　　Lithium-ion battery (LIB) has become the main energy storage solution in modern social life. Among them, lithium iron phosphate batteries are a perfect replacement for lead-acid batteries, and they are the first choice for grid-connected peak shaving, off-grid energy storage, photovoltaic energy storage, UPS, data center and other industries.

　　Solar power generation system with lithium battery energy storage system is a very promising clean energy.
