Connect to PV Panel DC input, Checking | AEG PV 2000 instruction

Connect to PV Panel (DC input)

1.Make sure the maximum open circuit voltage (Voc) of each PV string is less than 450VDC UNDER ANY CONDITION. We recommend Voc less than 360VDC with ambient temperature of 25C.

2.Use MC 3 (Multi-contact) connectors for PV array terminals.

3.Connect the positive and negative terminals

from the PV panel to positive (+) terminals and negative (-) terminals on the PV-Inverter. Each DC terminal on Protect PV endorses 20ADC

Before connecting PV panels to DC terminals, please make sure the polarity is correct. Incorrect polarity connection could permanently damage the unit.

Check short-circuit current of the PV string. The total short-circuit current of the PV string should be less than the inverter’s maximum DC current.

High voltages exist when the PV panel is exposed to the sun. To reduce risk of electric shock, avoid touching live components and treat connec- tion terminals carefully.

Checking

1.When the PV panels are connected and their output voltage is greater than 100 VDC but the AC grid is not yet connected, the message on the LCD display produce the following messages in order: “MODEL= XkW” -> “Waiting” -> “No Utility”. The display repeats “No Utility” and the RED “fault LED” turns on.

2.Close the AC breaker or fuse between PV-Inverter and grid. The normal operating sequence begins.

3.Under normal operating conditions the LCD displays “Watt=xxxx xW”. That is the power fed to the grid. The green LED turns lights-up.

4.This completes the check.
