SolaX Power X1-Hybrid-6.0-D User Manual

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.
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.
X1-Hybrid G4 series inverters use active frequency offset method to
prevent islanding effect.

Safety
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.
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 least 1 Mohm) 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).
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.
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.

• All inverter incorporate a certified internal Residual Current Device
(RCD) in order to protect against possible electrocution and fire hazard in
case of a malfunction in the PV array, cables or inverter .There are 2 trip
thresholds for the RCD as required for certification (IEC 62109-2:2011).
The default value for electrocution protection is 30mA,and for slow rising
current is 300mA.
• If an external RCD is required by local regulations ,check which type of
RCD is required for relevant electric code. It recommends using a type-A
RCD. The recommended RCD values is 100mA or 300mA unless a lower
value is required by the specific local electric codes.
