Operating characteristics | It can operate independently and 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. The module has protection measures such as over-temperature, over-voltage, under-voltage, overload, over-current, short circuit and system self-diagnosis function. If there is a short circuit and other faults inside the module, it can be automatically protected without affecting the external power system. When the compensation capacity required by the load is greater than the rated compensation capacity, it can continue to compensate according to the output capacity of the body, and stop running without overloading or causing equipment damage. |
