VGChartz recently announced global game hardware sales as of March 10, 2012, of which 3DS sales were more than 16 million, which is about 10 times that of PSV. The sales volume of PSV two days before its listing was 321,407, but it still fell to 371,326 units of 3DS. Shortly after the launch of the 3DS game console, sales began to decline, which resulted in Nintendo reducing the price of 3DS game consoles and lowering the company’s profit forecast this year.
Sony acknowledged that it was a mistake to introduce a 32GB memory card when the PS Vita was released in Europe. Fergal Gara, vice president of Sony Computer Entertainment UK, said on Tuesday: “We have learned from the early sales of PS Vita in Japan. We may not have enough memory cards to launch in the UK market. But we have already taken Measures to obtain larger capacity memory cards and they are imported into the UK market."
In 3DS, President Nintendo Iwata also said in the 3rd quarter performance briefing: "At present, the sale of 3DS in Asia is planned to begin in the next fiscal year. The specific release date and price will be released locally. Please look forward to further news."
In addition, VGChartz has published the sales data report of the US game market in November. The report also mentioned that 3DS performed well and the sales volume increased significantly.
The main function of the Solar Charge Controller is to manage the charging and discharging process between the Solar Panel and the battery in the solar power generation system. Its main function is to protect the battery from overcharge and over-discharge damage, ensure battery charging efficiency, and stabilize the operation of the solar power generation system.
Main effect:
Charge control: The solar charge controller controls the charging process by monitoring the voltage and current generated by the solar panel to ensure that the battery is charged at the appropriate voltage and current to extend the battery life.
Overcharge protection: The solar charge controller can monitor the charging status of the battery, and when the battery is fully charged, it will automatically stop charging to avoid battery damage caused by overcharging.
Over-discharge protection: The solar charge controller can monitor the discharge state of the battery. When the battery power is lower than a certain level, it will automatically stop discharging to avoid battery damage caused by over-discharge.
Differences from other charge controllers:
The solar charge controller is a charge controller specially designed for solar power generation systems, the main differences are as follows:
Applicable Energy: The solar charge controller is suitable for solar power generation systems, mainly used to manage the charging and discharging process between solar panels and batteries. While other charge controllers may be suitable for different energy generation systems, such as wind energy, hydro energy, etc.
Charging characteristics: The solar charge controller is optimized for the characteristics of the solar panel, and can control the charging process according to the output power and voltage characteristics of the solar panel. Other charge controllers may be optimized for different types of energy generation characteristics.
Protection function: Solar charge controllers usually have overcharge protection and over-discharge protection functions to ensure the safe charging and discharging of batteries. Other charge controllers may have different protection functions, depending on the needs of the application scenario.
Overall, the main role of the solar charge controller is to manage the charging and discharging process in the solar power generation system, protect the battery from damage, and stabilize the system's operation. Compared with other charge controllers, it is optimized for the characteristics of solar power generation systems and has unique functions such as overcharge protection and over-discharge protection to meet the needs of solar power generation systems.
