10.1 AC arrester kit
SMART TL inverters may optionally have built-in overvoltage protection on the AC input.
Overvoltage protection is Type II, with the following characteristics:
Nominal current 20 kA (8/20 uS)
Maximum current 40 kA (8/20 uS)
Residual voltage < 1.5 kV
Overvoltage protections limit the power coming from the grid due to atmospheric disturbances
and transient overvoltages on the grid. Their power dissipation is limited. If the protections
exceed the power they can withstand, they self-protect by opening their main circuit connection,
emitting a signal that is read by the control, triggering in turn an alarm and a shutdown of the unit.
When this occurs, the following alarm appears:
0x0100 AC circuit protection.
When this happens, the arresters show an error message on their display screen, changing
colour
In these cases, INGETEAM ADVISES CHANGING THE ENTIRE ARRESTER BLOCK.
10.2 DC arrester kit
SMART TL inverters may optionally have built-in overvoltage protection on the DC input.
Overvoltage protection is Type II, with the following characteristics:
Nominal current 20 kA (8/20 uS)
Maximum current 40 kA (8/20 uS)
Residual voltage < 4.5 kV
Overvoltage protections limit the power coming from the PV array due to atmospheric
disturbances and transient overvoltages. Their power dissipation is limited. If the protections
exceed the power they can withstand, they self-protect by opening their main circuit connection,
emitting a signal that is read by the control, triggering in turn an alarm and a shutdown of the unit.
When this occurs, the following alarm appears:
0x0200 DC circuit protection.
When this happens, the arresters show an error message on their display screen, changing
colour
In these cases, INGETEAM ADVISES CHANGING THE ENTIRE ARRESTER BLOCK.
