3.6.4 Steps for electrical connection
Danger
Danger
Please cover the photovoltaic battery board by lightproof
material or cut off the DC circuit breaker before electrical
connection. A dangerous voltage will be generated by the
photovoltaic matrix exposed in the sunshine.
If the inverter has been electrified and tested before conne-
ction, wiring cannot be performed unless the AC and DC power
supplies are cut off for 10min and a multimeter shows that
the DC side is totally discharged.
Caution
When designing the PV array, make sure the maximum open
circuit voltage is not higher than 550V at each series of PV
group. Otherwise the inverter will be damaged irreversibly.

Tip
Different colors of cables shall be used for differentiating
in assembling. E.g.: the positive pole is connected by a red
cable and the negative by a blue cable.
To balance each PV series, cables shall be with the same
sectional area.
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 DC loss.
High performance and high quality PV assemblies 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 in the PV grid-tied inverter.

Protect the LCD panel and other elements from scratch or
damage by cables or tools.
