2.4 Circuit Diagram
The Smart PCS implements rectification and inversion through a three-phase
three-level converter. The rectified output is converted from three-phase AC power
to DC power and then stored in the energy storage system (ESS). The inverted
output is filtered to a three-phase AC voltage, which is then isolated and boosted
by a three-phase transformer and fed into the power grid.

● If the DC indicator and running indicator do not blink red fast and the fault/
maintenance indicator is steady red, replace parts or the entire device.
● Local maintenance refers to the operation that requires inserting a WLAN module into
the USB port of the device, for example, connecting to the SUN2000 app through the
WLAN module.
● If alarms are generated during the local maintenance, the fault/maintenance indicator
shows the local maintenance state first. After the WLAN module is removed, the
indicator shows the alarm state.
