Ingeteam INGECON SUN PowerMax TL U B 1000 Vdc Series Installation And Operation Manual page 16

Ingeteam
The function of this kit is to generate the necessary power supply for the inverter's auxiliary services to operate,
thus avoiding the need to externally power the unit.
This kit is made up of a transformer with the suitable transformation for each of the INGECON SUN PowerMax B
model families.
The maximum consumption is 4250 W (25 A).
PV array depolarizer
The polarization of the photovoltaic panels may become degraded (Potential Induced Degradation, PID). Ingeteam
offers an optional PV array depolarizer that induces the necessary voltage to revert these effects.
DANGER
When the PV array generates low voltage (nighttime or other situations) this kit generates a voltage of 500 Vdc
between the negative pole of the PV panel and ground. Take into account this feature for the different tasks that
are to be carried out on the inverter.
To prevent the kit from generating voltage, the emergency stop button must be interlocked.
Communication accessories
There is various technology to communicate between units. For further information consult Section "12.
Connection of the communication accessories".
Integrated DC combiner box
Its purpose is to disconnect the PV array before the DC fuses. This solution is completely integrated in the DCAC
connections module.
Sand trap
For locations where environmental and terrain conditions require additional protection against sand entering
through the ventilation system.
This kit consists of a sand trap system in the front ventilation grilles.
Bottom cover
The bottom cover is a system designed to separate the DC supply from the ancillary and communication cable
entry. The ancillary and communication cables are inserted in the unit through the lower side hole in the inverter.
A 48 mm conduit must be connected.
