Introduction
2. Safety Instructions
2.1 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.
2.2 Operator Requirements
The operators should get a professional qualification, or trained.
The operators should be familiar with the whole storage system, including compositions and
working principles of the system.；
The operators should be familiar with the Product Instruction.
While carrying out maintenance work it has to be at least two operators in the filed all the time.
They can’t operate on any equipment until they are all powered off and fully discharged.
It is strictly prohibited for any maintenance to be carried out when equipment are on or
charged.
2.3 Protection of Warning Sign
The warning sign contains important information for the system to operate safely and it is
strictly prohibited to torn or damage the sign.
Ensure that the warning sign is always clear.
The signs should be replaced immediately if damaged.
2.4 Setting of Warning Sign for Safety
While instructing, maintaining and repairing, to prevent unrelated personnel nearby to cause
incorrect operation or accident, the suggestions 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 the operation areas.
Keys of the system must be pulled out after maintenance or operation.

Introduction
2.5 Live Line Measurement
High voltage in the container which may cause vital electric shock when touched 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.
2.6 Measuring Equipment
To ensure 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.
2.7 Electrostatic Prevention
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.
2.8 Moisture Prevention
It is very likely that moisture may cause damages to the system.
Do not open the container door if the humidity is larger than 95%.
Repair or maintaining activities in wet conditions should be avoided or limited.
2.9 Operation After Power Failure
The battery system belongs to energy storage system, which maintains fatal high voltage even
when the DC side is disconnected. Therefore, touching of the battery output is strictly
prohibited.
The PCS maintains fatal voltage even when both the DC or AC side are disconnected, so it
must be tested by the multimeter for safety before operation.
2.10 Minimum Personal Protective Equipment
For the safety of operators to the system, personal protective equipment are required. During
the operation, following protective equipment are required:
No.

3.3 Parameters of Components
3.3.1. PCS
3.3.1.1 Product Instruction
Storion-T50/T100-INV is a hybrid inverter. It has DC/DC and DC/AC modules. It can transform
the DC electricity from PV panels into three-phase AC electricity to supply loads. The DC/DC
module can charge batteries by using the electricity generated by PV panels. The DC/AC
module is bidirectional so that the battery can also be charged by the grid through the inverter.
