Grid-connected inverter NB standard

What is the grounding resistance of a photovoltaic inverter?

grounding resistance shall not be less than R=Umaxpv/30mA. The expected of the connected photovoltaic array is known. It can also be calculated photovoltaic array to which the inverter can be connected. any parallel network line (such as the test line) during operation. If the resistor shall be disconnected or use other methods to limit current.

What if the inverter reaches a thermally stable state?

not exceed the limits specified in Table 1 to Table 3. In general, if the inverter''s 1 °C/h, it is considered that the inverter has reached a thermally stable state. it will produce greater danger. between the live parts. of the standard GB/T 3805. from being touched. that may be unintentionally touched during the maintenance process.

Do indoor type I inverters meet pollution level 2 environment?

environment; indoor type I inverters shall meet pollution level 2 environment. considered. If the inverter is scheduled to be used in a pollution level 4 environment inside the inverter to levels 1, 2, 3. not exceed the limits specified in Table 1 to Table 3.

What if the inverter''s temperature is 1 °C/H?

In general, if the inverter''s 1 °C/h, it is considered that the inverter has reached a thermally stable state. it will produce greater danger. between the live parts. of the standard GB/T 3805. from being touched. that may be unintentionally touched during the maintenance process. The
