1.1 System Introduction
SMILE-B3 is an AC coupled all-in-one battery energy storage system (BESS). It can help
to achieve the optimal usage of renewable energy. SMILE-B3 can control the
bi-directional flow of electric power, work under auto/manual & time-of-use (TOU)
modes, charge/discharge the battery as per customer' s setting. Under the auto mode,
SMILE-B3 will store surplus renewable energy onto the battery and discharge battery to
supply power to local loads when renewable energy is not enough. SMILE-B3 is
equipped with 3 buttons, friendly human machine interaction system. More importantly
SMILE-B3 is stable, safe, and reliable. The standard schematic is shown in Figure 1.1:

NOTE:
For the AC coupled system with PV, if only install the Grid CT, the system cannot
display the power generated by PV inverter, electric energy production etc.
If there is no PV, the schematic is as below:

1.2 General Precautions
DANGER
Danger to life due to high voltages of battery and electric shock.
Do not touch uninsulated cable termination.
Do not touch the DC wires.
Do not open the inverter and battery.
Do not use wet cloth to wipe the system.
Do not dispose of batteries in fire. The batteries may explode!
Only qualified personnel with the corresponding skills can install and debug the system.
Before performing any work on the inverter or battery pack, please disconnect the inverter
Grid
from all voltage sources as described in this document.
WARNING
Risks of chemical burn electrolyte or toxic gases.
During standard operation, electrolyte won't leak from the battery pack as well
as form of toxic gases. However, when the battery pack is damaged or broken
down, electrolyte may leak or form toxic gases.
Do not install the system in temperature or humidity exceeding the permitted range.
Please do not use wet hands to touch the system.
Do not place heavy objects on the top of the system.
Do not damage the system using sharp objects.
Do not install or operate the system in the inflammable and explosive environment or high
humidity environment.
Do not install explosive gas and the battery pack in the area that containing highly
flammable substance or gas.
If the moisture penetrates the system (e.g. due to casing damage), please do not install or
operate the system.
When the system has connected the extended battery module, please do not move the
system.
Use strapping if necessary during transportation to prevent tipping.
Grid
SMILE-B3 transport must be conducted by the manufacturer or professionals, these
operations should be recorded and used.
Certified ABC extinguishers with minimum capacity 2 kg must be carried during transporta-
tion.
No smoking during unloading of vehicles and close to them.
If you want to replace the battery module, please pack new dangerous packaging according
to needs, pack them and let the supplier receive them.
If contacting with the electrolyte, please wash affected area with water immediately, and
consult a doctor immediately.
Risk of injury by hoisting or falling system
Inverters and batteries are heavy and can cause personal injury if the inverter or battery is
improperly lifted or dropped during transport or when attached or removed from walls.
Lifting and transporting SMILE-B3 is conducted by more than 1 person.
