1.2 Operation Modes:

There are three basic modes that end users can choose via inverter screen/APP.

- SELF CONSUME: The energy generated by the solar panels will be used in the following order: Feed the home loads; Charge the battery and then, feed into the grid. When the sun is off, the load will be supported by battery to enhance self consumption. If the power supply from the batteries is not sufficient, the grid will support the load demand.

graph TD
    A["太阳能电池图标"] --> B["中央设备"]
    C["电池图标"] --> B
    D["光伏电池图标"] --> B
    B --> E["灯泡图标"]

- BAT PRIORITY: Under this mode, the battery is only used as a backup power supply when the grid falls and as long as the grid works, the batteries won't be used to power the loads. The battery will get charged with the power generated by the PV system or from the grid.

System Operation

3.1 Switch On

When turning on the system, it is very important to follow the steps below to prevent damage to the system.

WARNING: Please check the installation again before turning on the system.

Technical line drawing of a refrigerator with an inset close-up showing internal components (no text or symbols)

Step 1:
Turn on the external PV switch.
Step 2
Turn on the external grid switch.
Step 3:
If backup load is applied, turn on the external Backup switch.

NOTE:

the Backup switch is only used when a backup load is applied.

Step 4

Open the outer shell of the cable box. Open the battery switch cover and turn on tery switch on the cable box.

Step 5:

Press power button on all the batteries until the indicator lights turn on.

Step 6

Close the battery switch cover and the outer shell of the cable box.

3.2 Switch Off

Step 1: Press the power button on all the batteries, till the lights turn off.

Step 2: Open cable box outer shell, open the battery switch cover and turn off the battery switch.

Step 3: Turn off the external grid switch.

Step 4: If backup load is applied, turn off the external backup switch.

Step 5: Turn off the external PV switch on the cable box.

Step 6: Close the battery switch cover and the outer shell of cable box.

3.3 Emergency Procedure

When the BluE-H5/H3 energy storage system appears to be running abnormally, you can turn off the grid-connected main switch that directly feeding the BESS, and turn off all load switches within the BESS, turn off the battery switch at the same time. To prevent a potentially fatal personal injury, if you want to repair or open the machine after the power is switched off, please measure the voltage at the input terminals with a suitably calibrated voltage tester. Before working on this equipment, please confirm that there is no grid electric supply to the BESS! The upper cover plate cannot be opened until the DC-link capacitance inside the battery modules discharges completely about 15 minutes later.

3.3.1 Emergency Handling Plan

1. Disconnect the AC breaker.

2. Check the control power supply. If it is OK, return the power supply to find out the reason.

3. Please record every detail related to the fault, so Kstar can analyse and solve the fault. Any operation of equipment during a fault is strictly forbidden, please contact Kstar as soon as possible.

4. As battery cells contain a little Oxygen inside and all cells have got explosion-proof valves, explosion hardly happens.

5. When the indicator light on the battery shows a red fault, check the fault type through the communication protocol, and contact our after-sales service personnel for advice.

3.3.2 Hazards

If the battery pack leaks electrolyte, avoid contact with the leaking liquid or gas. If one is exposed to the leaked substance, immediately perform the actions described below:

Inhalation: Evacuate the contaminated area, and seek medical attention.

Eye contact: Rinse eyes with running water for 5 minutes, and seek medical attention.

Contact with skin: Wash the affected area thoroughly with soap and water, and seek medical attention.

Ingestion: Induce vomiting and seek medical attention.

■ 31 www.kstar.com

3.3.3 Fire

If a fire breaks out in the place where the battery pack is installed, perform the following countermeasures:

Fire extinguishing media

During normal operation, no respirator is required. Burning batteries can not be extinguished with a regular fire extinguisher, this requires special fire extinguishers such as the Novec 1230, the FM-200 or a dioxin extinguisher. If the fire is not from a battery, normal ABC fire extinguishers can be used for extinguishing.

Fire -fighting instructions

1. If fire occurs when charging batteries, if it is safe to do so, disconnect the battery pack circuit breaker to shut off the power to charge.
2. If the battery pack is not on fire yet, extinguish the fire before the battery pack catches fire.
3. If the battery pack is on fire, do not try to extinguish but evacuate people immediately.

There may be a possible explosion when batteries are heated above 150^ C. When the battery pack is burning, it leaks poisonous gases. Do not approach.

Effective ways to deal with accidents

Battery in dry environment: Place damaged battery into a segregated place and call local fire department or service engineer.

Battery in wet environment: Stay out of the water and don't touch anything if any part of the battery, inverter, or wiring is submerged.

Do not use a submerged battery again and contact the service engineer.

10 Routine Maintenance

10.1 Maintenance Plan

◆ Check if wire connections are loose.
◆ Check if cables are aged/damaged.
◆ Check if cable insulating ribbon drops.
◆ Check if cable terminal is loose, any overheat sign.
◆ Check if ground connection is good.

10.1.1 Operating Environment

(Every six months)

Carefully observe whether the battery system equipment is ineffective or damaged;

When the system is running, listen to any part of the system for abnormal noise;

Check whether the voltage, temperature and other parameters of the battery and other equipment parameters are normal during system operation;

10.1.2 Equipment Cleaning

(Every six months to one year, depending on the site environment and dust content, etc.) Ensure that the ground is clean and tidy, keep the maintenance access route unblocked, and ensure that the warning and guiding signs are clear and intact. Monitor the temperature of the battery module and clean the battery module if necessary.

10.1.3 Cable, Terminal and Equipment Inspection

(Every six months to one year)

◆ Check if the cable connections are loose.
◆ Check whether the cables are aged / damaged.
◆ Check whether the cable tie of the cable has fallen off.
- Check if the cable terminal screws are loose and the terminal position has any signs of overheating.
◆ Check whether the management system of the system equipment, monitoring system and other related equipment are invalid or damaged.
◆ Check that the grounding of the equipment is good and the grounding resistance is less than 10 ohms.

10.2 Notes

After the equipment is out of operation, please pay attention to following notes while maintaining :

• Related safety standards and specifications should be followed in operation and maintenance.
  ◆ Disconnect all the electrical connections so that the equipment would not be powered on.
• Wait at least 5 minutes after disconnection, so that the residual voltage of the capacitors drops to a safe voltage. Use a multimeter to make sure that the equipment is completely discharged.
• The equipment should be repaired by professional staff only and it is strictly forbidden for maintenance staff to open equipment modules on their own.
  ◆ Appropriate protective measures should be taken while maintaining, such as insulated gloves, shoes, and anti-noise ear plugs.
  ◆ Life is priceless. Make sure no one would get hurt first.
  In case of a deep discharge, the battery must be charged to a SOC rate of 30% to 50% if the entire system is static (ie the battery has not been charged for two weeks or more).

Please contact us in time if there are any conditions that could not be explained in the manual.
