04

Warning！

Authorized service personnel must disconnect both AC and DC
power from inverter before attempting any maintenance or
cleaning or working on any circuits connected to inverter.

05

Surge protection devices (SPDs) for PV installation

►

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.

Lightning will cause a damage either from a direct strike or from surges due to a
nearby strike.

Induced surges are the most likely cause of lightning damage in majority or installations,
especially in rural areas where electricity is usually provided by long overhead lines.
Surge may be included on both the PV array conduction and the AC cables
leading to the building.

Specialists in lightning protection should be consulted during the end use application.
Using appropriate external lightning protection, the effect of a direct lightning
strike into a building can be mitigated in a controlled way, and the lightning
current can be discharged into the ground.

Installation of SPDs to protect the inverter against mechanical damage and
excessive stress include a surge arrester in case of a building with external
lightning protection system (LPS) when separation distance is kept.

To protect the DC system, surge suppression device (SPD type2) should be fitted
at the inverter end of the DC cabling and at the array located between the
inverter and the PV generator, if the voltage protection level (VP) of the surge
arresters is greater than 1100V, an additional SPD type 3 required for surge protection
for electrical devices.

To protect the AC system, surge suppression devices (SPD type2) should be
fitted at the main incoming point of AC supply (at the consumer ’s cutout),
located between the inverter and the meter/distribution system; SPD (test
impulse D1) for signal line according to EN 61632-1.

All DC cables should be installed to provide as short a run as possible, and positive
and negative cables of the string or main DC supply should be bundled
together. Avoiding the creation of loops in the system. This requirement for
short runs and bundling includes any associated earth bundling conductors.

Spark gap devices are not suitable to be used in DC circuits once conducting,
they won’t stop conducting until the voltage across their terminals is typically
below 30 volts.

Anti-Islanding Effect

►

Islanding effect is a special phenomenon that grid-connected PV system still
supply power to the nearby grid when the voltage loss is happened in the
power system. It is dangerous for maintenance personnel and the public.
X1-Hybrid seires inverter provide Active Frequency Drift(AFD) to prevent
islanding effect.

06

Saf etySa fet y

►

PE Connection and Leakage Current

• 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.

The device is intended to connect to a PV generator with a capacitance limit of
approx 700nf.

WARNING !

High leakage current!
Earth connection essential before connecting supply.

• Incorrect grounding can cause physical injury, death or equipment malfunction
and increase electromagnetic.

• Make sure that grounding conductor is adequately sized as required by safety
regulations.

For United Kingdom

• The installation that connects the equipment to the supply terminals shall
comply with the requirements of BS 7671.

• Electrical installation of PV system shall comply with requirements of BS 7671
and IEC 60364-7-712.

• No protection settings can be altered.

• User shall ensure that equipment is so installed, designed and operated to
maintain at all times compliance with the requirements of ESQCR22(1)(a).

X1-Hybrid Series inverter provides multiple work modes based on different
requirements.

Work modes: Self-use (with PV Power)

Priority: load>battery>grid

This mode applies the area that has low feed­in tariff and high energy price.

The power generated from PV will be used to
supply the local loads firstly, then to charge
the battery. The redundant power will export
to the public grid.

Work modes: Self-use (without PV Power)

When no PV supplied, battery will discharge
for local loads firstly, and grid will supply
power when the battery capacity is not
enough.

Work modes: Force time use

Priority:battery>load>grid(when charging)
Priority:load>battery>grid(when discharging)

This mode applies the area that has electricity
price between peak and valley. User can use
off-peak electricity to charge the battery.

The charging and discharging time can be set
flexibly, and it also allows to choose whether
charge from the grid or not.

3.3 Dimension

Work modes: Back up mode

Priority:battery>load>grid

This mode applies the area that has frequent
power outages. And this mode ensures the
battery will has enough energy to supply
when the grid is off.

In this mode battery will be charging forcibly
in the setting time and will never be
discharged when the grid is on, and it also
allows to choose whether charge from the
grid or not.

EPS Status

When the grid is off, system will supply
emergency power from PV or battery to
supply the home loads. (Battery is necessary
in EPS mode.)

180 .0 mm

power through EPS port when the the grid is off.

I Version & E Version

Ø

X1-Hybrid series inverter provides two versions for customer to choose based on
the local rules.
“I Version” means inverter has an build-in changeover switch. This version applies
to the wiring rules which requires Neutral line of alternative supply must not be
isolated or switched.(applies to wiring rules AS/NZS3000:2014 of Australia and
New Zealand.)
“E Version” means inverter needs to install an external changeover device for EPS
function. This version applies to the wiring rules which allows Neutral line of
alternative supply can be isolated or switched.( applies to most of the countries)

Auto & Manual

Ø

EPS function can be achieved automatically or manually according to user’s wishes.
For “I Version” inverter, EPS function can only be triggered automatically.
For “E Version” inverter, EPS function can be triggered either automatically or
manually according to user’s preference.
If user wants to use this function manually, it will need to be installed an external
switch. Please refer to specific wiring diagram below.
