PAP
• Prior to the application, please read this section carefully to ensure correct and safe
application. Please keep the user manual properly.
• Accesories only together with the inverter shipment are recommended here. Otherwise
may result in a risk of fire, electric shock, or injury to person.
• Make sure that existing wiring is in good condition and that wire is not undersized.
• Do not disassemble any parts of inverter which are not mentioned in installation guide.
It contains no user-serviceable parts. See Warranty for instructions on obtaining service.
Attempting to service the inverter yourself may result in a risk of electric shock or fire
and will void your warranty.
• Keep away from flammable, explosive materials to avoid fire disaster. The installation
place should be away from humid or corrosive substance.
• Authorized service personnel must use insulated tools when installing or working with
this equipment.
• PV modules shall have an IEC 61730 class A rating.
• Never touch either the positive or negative pole of PV connecting device.
• Strictly prohibit touching both of them at the same time.
• The unit contains capacitors that remain charged to a potentially lethal voltage after the
MAINS , battery and PV supply has been disconnected.
• Hazardous voltage will present for up to 5 minutes after disconnection from power
supply.
• CAUTION-RISK of electric shock from energy stored in capacitor, Never operate on the
inverter couplers, the MAINS cables, Battery cables, PV cables or the PV generator when
power is applied. After switching o ffthe PV , battery and Mains, always wait for 5minutes
to let the intermediate circuit capacitors discharge before unpluging DC ,battery inplug
and MAINS couplers.
• When accessing the internal circuit of inverter, it is very important to wait 5 minutes
before operating the power circuit or demounting the electrolyte capacitors inside the
device. Do not open the device before hand since the capacitors require time sufficiently
discharge!
• Measure the voltage between terminals UDC+ and UDC- with a multi-meter(impedance
at least 1Mohm) to ensure that the device is discharged before beginning work (35VDC)
inside the device.
Surge protection devices (SPDs) for PV installation
• 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 installa-
tions, 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 ine accord-
ing l 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.
• 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 more than 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
series inverter provide Active Frequency Drift(AFD) to prevent islanding effect.
PE Connection and Leakage Current
• The end-use application shall monitor the protective conductor by residual current
operated protective device (RCD) with rated fault current Ifn≤240mA which automatically
disconnects the device in case of a fault. The device is intended to connect to a PV
generator with a capacitance limit of approx 700nf.
• 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 regula-
tions.
• Do not connect the ground terminals of the unit in series in case of a multiple installa-
tion. This product can cause current with a d.c component, Where a residual current
operated protective (RCD) or monitoring (RCM) device is used for protection in case of
direct or indirect contact, only an RCD or RCM of type B is allowed on the supply side of
this product. 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 ensur e that equipment is so installed, designed and operated to maintain at
all times compliance with the requirements of ESQCR22(1)(a). For Australia and New
Zealand
• Electrical installation and maintenance shall be conducted by licensed electrician and
shall comply with Australia National Wiring Rules. Battery Safety Instructions BD series

battery type, nominal voltage and nominal capacity etc., please refer to section 4.3. As
accumulator batteries may contain potential electric shock and short-circuit current
danger, to avoid accidents that might be thus resulted, the following warnings should be
observed during battery replacement:
1: Do not wear watches, rings or similar metallic items.
2: Use insulated tools.

INTRODUCTION
Hybrid Inverter series is a high quality inverter which can convert solar ene rgy to AC
energy and store energy into battery
The inverter can be used to optimize self consumption, store in the battery for future use or
feedin to public grid. Work mode depends on PV energy and user's preference. It can
provide power for emergency use during the grid lost by using the energy from battery and
inverter(generated from PV).

cation line.
6.All the above wiring and operations must be carried out after the whole machine is
powered down, and all of them need professional personnel to complete
Power Connection Steps:
Step 1. Choose the 4AWG wire and strip the cable to 15mm.
Step 2. Select two O-terminals with an aperture of M6.
Step 3. Insert the stripping line into the O-terminal and clamp it with a crimping clamp.
Step 4. Remove waterproof cover plate.
Step 5. Disassemble the waterproof connector and pass the cable through the waterproof
connector.
Step 6. Connect the cable to the terminal of the inverter .
Step 7. Assemble waterproof connectors and waterproof covers plate.
Step1,2,3.

Communication interface definition
BMS PIN Definition
Communication interface between inverter and battery is RS485 or CAN with a RJ45
connector.
The wiring sequence of the crystal head conforms to the 568B standard: orange
white, orange, green white, blue, blue white, green, brown white and brown.
DRY_IO (RJ45 PIN) Definition
Reserved dry contact interface of the inverter.
WiFi And GPRS Connection(optional)
Inverter provides a WiFi port which can collect data from inverter and transmit it to
monitoring-website by WiFi.
Step1. Plug Wifi into “COM” port at the bottom of the inverter.
Step2. Build the connection between the inverter and router.
Step3. Create a user account online. (Please check the WiFi user manual for more
details).
DRM Connection
DRM is provided to support several demand response modes by emitting control
signals as below.
