WARNING

Before proceeding with the DC wiring, completely cover the surface of all PV panels

with dark material to avoid the production of electrical current.

WARNING

Make sure the polarity and the PV panel voltage between the positive and the nega-

tive cable connectors of the PV panels are correct before connecting the panels to the

DC terminal block on the power distribution board.

The PV array open circuit voltage should be at or below the listed voltages in Table 3-4

under all circumstances. Each DC input to the DC terminal block must be less than the

voltages listed in Table 3-4.

Open Circuit Calculations

The PV array open circuit voltage should be at or below 500 VDC under all

circumstances. Each DC input to the DC terminal block must be less than 500 VDC.

DC Connections

Each DC input connection must carry the same input voltage. The inverter allows up to

three connections for both the positive and negative poles.

To wire the DC inputs from the PV array to the inverter (see Figure 3-11):

Calculate the maximum open circuit voltage (V1.

) for each series of modules based

on the VOC_TC, in accordance with the expected lower temperature, and accepted

industry practice.
