Operating characteristics | It can operate safely and stably around the clock, without affecting the normal operation of other equipment in the system, and without endangering the security of the power grid. There are protection measures such as over-humidity, over-voltage, under-voltage, overload and over-current, short circuit and system self-diagnosis function inside the module. If a fault such as a short circuit occurs inside the module, it can be automatically protected without affecting the external power supply system. The compensation energy required by the load is greater than the rated compensation energy, which can be output according to the capacity of the body and continue to compensate, without overloading or causing equipment damage and exiting operation |
