2.3.c Connecting DC Wires/PV Panels

WARNING: Before proceeding with the DC wiring, completely cover the

surface of all PV-arrays with dark material to avoid the production of electrical

current.

WARNING: Make sure the polarity and the PV panel voltage between the +

and the – cable connectors of the PV panels are correct. Then connect the

panels to the DC terminal block on the power distribution board.

The PV panel open circuit voltage should be at or below the listed voltages in Figure 14

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

voltages listed in Figure 14.

Figure 14: PV open circuit voltages.

To wire the DC inputs from the PV panels to the StarInverter (refer Figure 15):

Note: Each DC input connection must carry the same input voltage. The StarInverter

allows up to three connections for both the + and the – pole.

1. Calculate the maximum open circuit (no load) for each series panel connection.

FOR ALL TEMPERATURE CONDITIONS, THE OPEN CIRCUIT VOLTAGE

FOR EACH SERIES CONNECTION MUST TOTAL LESS THAN THE OPEN

CIRCUIT VOLTAGE INDICATED IN FIGURE 14 FOR THE

CORRESPONDING STARINVERTER MODEL. Review your panel’s data sheet

for operating temperature ranges.

2. Keep track of the array positive and negative leads and mark them clearly.

3. Route the PV array leads through the far right opening in the StarInverter.

4. Connect each series positive DC lead to the positive terminals of the power

distribution board.
