PVP250kW & PVP260kW Inverter

Installation & Operation Manual

Adjustable Voltage Range

The inverter is factory calibrated to the voltage and frequency limits detailed in

Appendix

D - Limits, Fault Codes, Torque Values, and Wire Sizes

. These limits are adjustable and

can be set by PV Powered eld technicians.

4.7 DC Wiring

DANGER

Before proceeding with the DC wiring, conrm that the PV array has been

disconnected from the inverter using the external DC disconnect.

DANGER

Avant d’effectuer les branchements CC, assurez-vous que les piles PV sont

déconnectées de l’onduleur en utilisant le connecteur CC externe.

DANGER

Make sure the PV array polarity and voltage between the positive and

negative cables are correct before connecting the PV array cables to the DC

terminal block.

DANGER

Assurez-vous que la polarité et le voltage des câbles positifs et négatifs des

piles PV sont corrects avant de brancher les câbles des piles PV aux bornes

CC.

The three DC busbars, positive, negative and ground are located in the lower left of the

DC panel. Refer to Figure 4-14. The positive and negative bars are vertically mounted

and the ground bar is horizontally mounted at the bottom of the cabinet. The positive

and negative busbars have 32 rows of two 3/8” diameter holes spaced 1” apart vertically.

The ground bar has 12 rows of two 3/8” diameter holes spaced 1” apart. See

Appendix D

Table D-10 for wire sizing limits for inverters with an optional fused subcombiner.

DC Input Voltage

Calculate the maximum open circuit (no load) voltage for each series module connection.

FOR ALL TEMPERATURE CONDITIONS, THE OPEN CIRCUIT VOLTAGE FOR

EACH SERIES CONNECTION MUST BE LESS THAN OR EQUAL TO 600 VDC.

Contact PV Powered if you require assistance calculating the maximum DC input voltage

for your array at your specic location.

DC Inputs

Each DC input connection must be wired to deliver the same input voltage.
