The appliance is not to be used by children or perso ns with reduced physical sen sor y or menta l capabilities, or lack of experience and k nowledge, unless they have been given supervision or instruc tion. Children should be supervised to ensure that they do not play with the appliance.

Caution! Danger of burn injuries due to hot enclosure parts!

During operation, the upper lid of the enclosure and the enclosure body may become hot. Only touch the lower enclosure lid during operation.

Caution! Possible damage to health as a result of the effects of radiation!

Do not stay closer than 20 cm to inverter for any length of time.

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. The unit contains capacitors that remain charged to a potentially lethal voltage after the MAINS and battery have 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 or Battery cables when power is applied. After switching off the battery and Mains, always wait for 5 minutes to let the intermediate circuit capacitors discharge before unpluging 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 time to sufficiently discharge! require 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.

Warning！

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

Warning!

Do not operate the inverter when the device is running.

Warning!

Risk of electric shock!

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

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 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.

Anti-Islanding Effect

►

Islanding effect is a special phenomenon that grid-connected 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. X3-Retro Fit 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.

The external generator generated power will be used to

supplythe local loads firstly, then to charge the battery. The Self Use (default)

redundantpower will export to the public grid.

When there is no external generator supplied, battery will

discharge for local loads firstly, and grid will supply power when

the battery capacity is not enough.

Battery will stop discharing to keep higher capacity when the

grid is on. Only when the gird is off and the power generated is

Back Up Mode

not enough, battery will start to discharge to keep the

emergency load working normally.

This work mode applies to the area where suffering from

blackout regularly.

g-2-2) EPS system ( For E Version only) X3-Retro Fit inverter with E Version can work on the EPS mode. EPS parameters can be set as below. “Mute”means you can set the warning of system which has entered EPS mode.

-”No”means there will be a buzzing and it is the default value.

-”Yes”means you choose to shut down the warning function. Besides ,if the buzzing is sharp, it means EPS output is “over loads.“ Frequency “here can be set 50Hz or 60Hz please based on correlative loads.

“EPS auto restart” is used for restarting EPS output power manually or automatically. When the battery capacity reachs to min capacity or battery voltage reachs discharge cut voltage in oﬀ-grid mode, battery will stop discharging and the inverter will stop exporting power from eps port with showing “BAT power low” on LCD display.

- Choose “disable” means the EPS output power can only be restarted by pressing ESC button manually and it is the default value.

- Choose “enable” means the EPS output power can be restarted automatically through setting the “Min ESC Volt” (for lead-acid battery) or “Min ESC Soc” (for lithium battery).

For example, if user chooses “enable” and set “Min ESC Soc” to 20%, it means PV power from other inverter in one system will charge the battery and when battery capacity reachs 20%, inverter will restart EPS output power and” BAT Power low” will disappear.

X3-Hybrid inverter need to work with Energy meter to achieve hybrid functions. User also can turn off meter function so that X3-Hybrid inverter can work as normal grid-tied inverter without meter connected. In hybrid system, if there is other power device in the system which is also wanted to be monitored, It can install two meters to monitor both solax inverter and other power device. These two meters need to be set different to address. Address 001 and address 002 are default and will be written to meters in factory. So user do not need to change the address except specific situation.
