5.2.3 DC side voltage inspection 

The DC side shall be connected to the inverter from the Combiner or DC distribution 
cabinet.

Ensure correct DC input polarity. 

Measure  and  record  the  DC  voltage  of  each  line.  Voltages  of  each  line  shall  be 
similar, and less than the permitted maximum DC voltage value.

5.3 Power on steps

First power-on

First switched on PCS100 steps are as follow:

Step 1: Turn AC circuit breaker handle to "ON" position.

Step 2: Turn DC circuit breaker handle to "ON" position.

Step 3: After power on the system need to wait for about 30 seconds, the LCD will 
display properly;

Step 4: Choose on-grid or off-grid mode on LCD screen

Step 5: At on-grid mode, set the output power in the range of -250kW to 250kW

Step  6:  Inverter  starts  self-check,  connect  to  grid  or  local  load  when  self-check 
completed successfully.

Automatic power-on

When  the  dc  side  and  ac  side  meet  boot  conditions,  energy  storage  controller 
automatically switched on.

When  the  input  dc  or  ac  power  grid  after  fault  clearance,  storage  controller  will 
automatically boot.

Manual power-off

In operation process of the inverter, it can be powered off by clicking "OFF" button 
on the screen. At this moment, the inverter stops working.

CAUTION!

After  manual  power-off,  the  machine  must  be  powered  on 
manually, otherwise the inverter is unable to power on.

5.4 Pilot operation completion

The  following  procedures  shall  be  carried  out  after  the  inverter  is  normally  in 
operation.

Procedure  1:

  Inspect  whether  abnormity  exists  in  the  inverter,  such  as  excessive 

noise, excessive heat, abnormal smell or smoke.

Procedure 2: 

Measure whether inverter voltage, current and THD are stable.

Procedure  3: 

Operate  LCD  control  panel  and  inspect  whether  it  displays  normally 

and accurately.

By now, the pilot operation of inverter is fully completed, and we can enter the daily 
operational maintenance. 

5.5 Power off steps

CAUTION!

After  the  inverter  is  completely  powered  off,  the  general  DC 
switch at battery side and the Grid switch at grid side still maintain 
voltage.  If  operations  are  needed,  please  be  sure  to  cut  off  the 
outer power completely, and wait for not less than 5 minutes. 

1. Click the OFF button on LCD;
2. Cut off DC SWITCH;
3. Cut off GRID SWITCH;
4. Cut off the switch of DC distribution cabinet or combiner;
5. Cut off the switch of AC distribution cabinet.
