3.2 Application Scenarios

SMILE-B3-PLUS 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-PLUS 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-PLUS stores surplus renewable energy onto the battery and discharge battery
to supply power to local loads when renewable energy is not enough.
