Description
Standby The SUN2000 enters Standby mode when the external
environment does not meet the operating requirements. In
Standby mode:
● The SUN2000 continuously performs status check and enters
the Operating mode once the operating requirements are met.
● The SUN2000 enters Shutdown mode after detecting a
shutdown command or a fault after startup.
Operating In Operating mode:
● The SUN2000 converts DC power from PV strings into AC power
and feeds the power to the power grid.
● The SUN2000 tracks the maximum power point to maximize
the PV string output.
● If the SUN2000 detects a fault or a shutdown command, it
enters the Shutdown mode.
● The SUN2000 enters Standby mode after detecting that the PV
string output power is not suitable for connecting to the power
grid for generating power.
Shutdown ● In Standby or Operating mode, the SUN2000 enters Shutdown
mode after detecting a fault or shutdown command.
● In Shutdown mode, the SUN2000 enters Standby mode after
detecting a startup command or that the fault is rectied.
2.4.2 Circuit Diagram
The inverter connects to four PV strings and tracks the maximum power point of
the PV strings through two maximum power point tracking (MPPT) circuits. It also
converts DC power into three-phase AC power through an inverter circuit. Surge
protection is supported on both the DC and AC sides.
