including attentions.

(6) Trouble-shooting

Introduces the faults of T50/T100 Li-ion battery energy storage system, reasons to faults,

and processing method.

Explanation of Terms

(1) Lithium iron phosphate cell (LiFePO4)

Basic unit constituted by electric poles and electrolytes; Each cell is independent and

closed. (Notes: Paralleled cell cannot be regarded as an independent cell, even packed

again)

(2) Lithium iron phosphate pack

Combination made up of battery monitoring circuit, battery equalization circuit, electrical

connectors, communication interfaces, thermal management devices and multiple Lithium

iron phosphate cells(Notes: For packs from same company, all the details such as physical

size, working performance and interface specification should be consistent in order that all

the packs are interchangeable).

(3) Battery management system

Electronic equipment collection formonitoring the operating information of cells, packs and

system units (such as voltage, current, temperature, protective parameter of batteries),

evaluating the state of charge (SOC), the state of health (SOH) and cumulative

processed energy, protecting batteries for safety, etc.

(4) Battery system unit

Combination made up of batteries through series parallel combination inside and a battery

management system (BMS) in which accesses to DC side of a bidirectional converter.

(5) Storage unit

2. Safety Instructions

Manual Keeping

This manual contains important information about operating the system. Before operating,

please read it very carefully.

The PCS should be operated in strict accordance with the description in the manual, in

case that it causes damage or loss to equipment, personnel and property.

This manual should be kept carefully for maintenance and reparation.

Operator Requirements

The operators should get a professional qualification, or be trained.

The operators should be familiar with the whole storage system, including compositions

and working principle of the system.

The operators should be familiar with the Product Instruction.

While maintaining it must ensure that two operators are in the field, and they cannot

operate any equipment until all of them are powered off and fully discharged.

It is strictly prohibited for any maintenance when equipments are on or charged.

Protection of Warning Sign

The warning sign contains important information for the system to operate safely, and it is

strictly prohibited to be torn or damaged.

Ensure that the warning sign is always clear.

The signs should be replaced immediately when damaged.

Setting of Warning Sign for Safety

While instructing, maintaining and repairing, in case of preventing unrelated personnel

nearby to cause incorrect operation or accident, the opinions below should be followed:

Obvious signs should be set at front switch and rear-level switch in case of accidents

caused by false switching.

Warning signs or tapes should be set near operating areas.

Keys of the system must be pulled out after maintenance or operation.

Live Line Measurement

High voltage in the container which may cause vital electric shock when touching by

accident.

Equipment protection must be taken in live line measurements (e.g.: insulation gloves).

The measuring equipment should be connected and used correctly to ensure personnel

safety. When measuring, at least two workers are needed.

Measuring Equipment

For ensuring the electrical parameters to match requirements, related measuring

equipment are required when the system is being connected or tested.

Ensure that the connection and use matches specification in case of electric arc or shock.

Electrostatic Protection

Contact or improper operation of the printed circuit board or other ESD sensitive

components may result in damage to the device. Unnecessary contact should be avoided.

Moisture Protection

Moisture intrusion may highly likely well damage the system.

Do not open the container door when the humidity is larger than 95%.

Repair or maintaining activities in wet weather should be avoided or limited.

Operation After Power Failure

The batterysystem belongs to energy storage system, and it keepsfatal high voltage even

the DC side is disconnected, so touching the output of the battery is strictly prohibited.

The PCS keeps fatal voltage even both the DC or AC side are disconnected, so it must be

tested by multimeter for safety before operation.

Minimum Personal Protection Equipment

For the safety of operators to the system, when doing personal protective equipments are

required.

When stepping into the containers, as minimum the following protective equipments are

required:

No.

Item

Notes

Work clothes

Protective shoes

Protective glasses

When doing maintenance works such as checking cables or wires, measuring voltage,

replacing small electrical parts or cleaning modules and brackets, as minimum the

following protective equipments are required:

No.

Item

Notes

Work clothes

Protective shoes

Protective glasses

Insulated gloves

For touching live parts

Note: All metal tools during maintenance should be insulated.

3. Product Description

The AlphaESS T50/T100 energy storage system is an off-grid system. The excessive

energy generated by the PV will be stored in the batteries. The stored energy can be used

when the PV is not generating enough energy, for self-consumption at a certain time or to

shave off peak usage and fill valley usage.

The overall system connection diagram is as follows:

Figure 3-1 System application diagram

If your system without container, the overall system connection diagram is as follows:
