NO TICE
The recommended specications for the AC switch between the AC side of the
Smart PCS and the transformer station are as follows. Select a power distribution
switch that complies with local regulations based on actual application scenarios.
● Three-phase AC switch
● Rated voltage ≥ 800 V AC
● Rated current ≥ 200 A
● Breaking capacity > Short-circuit current on the transformer PCS side;
recommended: ≥ 10 kA. For example, if the rated capacity of the transformer is
3300 kVA and the short-circuit impedance is 7.8%, the short-circuit current is
about 30.5 kA.
Step 2 Turn on the DC switch between the DC side of the Smart PCS and the ESS.
NO TICE
The recommended specications for the DC switch between the DC side of the
Smart PCS and the ESS are as follows. Select a power distribution switch that
complies with local regulations based on actual application scenarios.
● DC switch
● Rated voltage ≥ 1500 V DC
● Rated current ≥ 250 A
● Breaking capacity > Short-circuit current on the ESS DC side; recommended: ≥
10 kA
Step 3 Check that the DC voltage is within the normal range on the FusionSolar app.
Step 4 Send a startup command on the FusionSolar app, SmartLogger, or management
system, and wait for the system soft start.
Step 5 Observe the LED indicators to check the running status of the Smart PCS.

and O for 1s)
Meaning
1 DC indication Steady green The DC side is properly connected, and
the auxiliary power supply inside the
device is working.
Blinking green slowly The device is in standby or wiring
inspection state.
Blinking red fast An environmental fault occurred on the
DC side.
