The device fits for both households and commercial applications. The series presents compact and lightweight inverters with an efficiency of 98.3 percent, equipped with Uninterruptible Power Supply (UPS) Function, backup overloading, AC charging functions and open-protocol EMS communication system, the company says.
Covering a power range of 5 kW, 8 kW and 10 kW, the ET Series allows 30 percent DC oversizing to fully maximize yield during extreme hot and cold weather and features a wide battery voltage range of 180 up to 550 volts to ensure customers flexibility choices and compatibility with different type of lithium battery. According to GoodWe, the device features UPS to inductive loads such as air conditioners or refrigerators with an automatic switchover time of less than 10 milliseconds, providing grid-tied savings when the grid is up and off-grid independence and security when it is down or compromised.
When installing ET Series, battery will not be damaged by accidental swap of the positive and negative polarity which help to ensures safety battery installation. Not only that, GoodWe ET allows backup overloading up to 100 percent, which allows quick restart for inductive load such as A/C while it will not cause harm to any electrical appliances. The inverter is also in-built with open-protocol EMS communication system as it ensures interconnections between grid companies and batteries to dispatch electricity freely. (nhp)
