Steps for DC cable wiring

Installation

DC cable between the inverter and the assembly shall be the

special PV cable. The voltage drop from the terminal box to the

inverter is about 1-2%. It is recommended the inverter is

installed on the assembly support for generation to reduce the

cable cost and the DC loss.

High performance and high quality PV array shall be used. The

open circuit voltage in the serial array must be lower than the

maximum DC input voltage in the PV grid-tied inverter, and the

working voltage of the serial array must comply with the MPPT

voltage of the serial array must comply with the MPPT voltage

in the PV grid-tied inverter.

● Protect the LCD panel during wiring;

● Protect the LCD panel and other elements from scratch or

damage by cables or tools.

1) Using the striping tool to cut the PV cable, and makes the cooper wire

reveal as 0.7cm.

In order to balance each PV series, Cable shall be with the same

sectional area.

Different colors of cables shall be used for differentiating in

assembling. For example: the positive pole is connected by a red

cable and the negative by a blue cable.

When designing the PV array, make sure the maximum

open circuit voltage is not higher than 1000V at each

series of PV group. Otherwise the inverter will be

damaged irreversibly

2) Insert cable into DC”+” terminal

3) Process crimping.
