WARNING !
Risk of electric shock!

• 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 recommanded 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 off the 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 to 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
WARNING !
Over-voltage protection with surge arresters should be provided when the PV power system is installed.
The grid connected inverter is not 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 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 seires inverter provide Active Frequency Drift(AFD) to prevent islanding effect.
► PE Connection and Leakage Current

• All inverters 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.When required by local regulations,the use of an RCD type B is permitted.
  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.

• Do not connect the ground terminals of the unit in series in case of a multiple installation. 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.

Introduction

3.1 Basic features
X1-Hybrid Seires is a high-quality inverter which can convert solar energy 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).
► System Diagram
X1-Hybrid Series is designed with two EPS versions for customer to choose based on the local rules.
E Version applies to the wiring rules that requires the Live line and Neutral line of EPS must be disconnected with the Live line and Neutral line of grid. (applies to most countires)

I Version applies to the wiring rules that requires Neutral line of alternative supply must NOT be isolated or switched (applies to wiring rules AS/NZS_3000:2012 for Australia and New Zealand).

Note!

• Please control the home loads, and make sure it’s within the “EPS output rating” under EPS mode, otherwise the inverter will shutdown with an “overlaod fault” warning.
• Please confirm with the mains grid operator whether there is any special regulations for grid connection.

3.2 Work Modes
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 feed-in 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 offpeak 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.
| Work modes:  Feed in Priority
Priority:load>grid>battery
This mode applies the area that has high feed-in tariff and export control.
The PV generated power will be used to supply the local loads firstly, then export to the public grid. The redundant power will charge the battery.
| 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.)
