SolaX Power X3-Hybrid Series User Manual

The islanding effect means that when the power grid is cut off, the
grid-connected power generation system fails to detect the power
outage and still supplies power to the power grid. This is very dangerous
for the maintenance personnel and the power grid on the transmission
line.
The inverter’s use active frequency offset method to prevent islanding
effect.

Safety
A photovoltaic module used on the inverter must have a IEC61730A
rating, and the total open circuit voltage of the photovoltaic string /
array is lower than the maximum rated DC input voltage of the
inverter. Any damage caused by photovoltaic over voltage is not
covered by warranty.
Installation position should be away from wet environment and
corrosive substances.
After the inverter and power grid cut off the PV power supply,there
will be a certain amount of residual current in a short time, be
cautious or it may lead to serious personal injury and even high risk
of death. Use a multimeter (impedance at least1 MΩ) to measure the
voltage between the UDC and the UDC- to ensure that the inverter
port is discharged below the safe voltage before starting operation
(35 VDC).
Warning!
Over-voltage protection with surge arresters should be
provided when the PV power system is installed.
The grid connected inverter is fitted with SPDs in both
PV input side and MAINS side.
Safety
If the building installed with external light protection device is
far away from the inverter location, in order to protect the
inverter from electrical and mechanical damage, the inverter
should also install an external lightning protection equipment.
In order to protect DC system, two-stage surge protection
equipment is needed between DC cable of inverter and
photovoltaic equipment module.
In order to protect the AC system, the level 2 surge protection
equipment should be installed at the AC output, located
between the inverter and the grid. Installation requirements
must comply with IEC61643-21 standard.
All DC cables shall be installed in a distance as short as possible,
and the positive and negative cables of the same input need to
be bundled together to avoid causing loops in the system.
Minimum distance installation and binding requirements also
apply to auxiliary grounding and shielding grounding
conductors.
Direct or indirect lightning strikes can cause failures. Surge is the
main cause of lightning damage to most devices. Surge voltage may
occur at photovoltaic input or AC output, especially in remote
mountain areas where long distance cable is supplied.
Please consult professionals before installing SPDs.
The external lightning protection device can reduce the inuence
of direct lightning strike, and the lightning protection device can
release surge current to the earth.
