Warning:
• After manually shutting down, you must press the power button on
the LCD, otherwise cannot start automatically.
• Still powered after manual shutdown
CAUTION!
When connecting the load,make sure that the three-phase of the load
is corresponding to the three-phase of the HPS, otherwise it will
cause the motor to reverse.
5.2.3 DC side voltage inspection
The DC side consists of two parts,from the confluence box or the DC distribution
cabinet to the HPS and from the storage battery to the HPS. Ensure that the direct
current from the confluence box or DC distribution cabinet is connected to the PV
terminal of HPS and is in sequence.
• Make sure the DC input polarity is correct;
• Measure and record each DC (open circuit) voltage. The voltage value of each
channel should be almost the same and should not exceed the maximum allowable
DC voltage value.
• Battery voltage check, battery parameter setting check
5.3 Power on steps
First power-on
Step 1: Close AC circuit breaker
Step 2: Close DC circuit breaker
Step 3: PV DC switch to ON position
Step 4: Click start on inverter display and wait till ‘grid connecting’
Note: when system is powered, 60S later about display will lit
Manual turn-off
During operation, you can click the shutdown button on the LCD, at this time the
inverter stops working and stops sending power to the grid
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.
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 20 minutes
During the power-off process, the energy storage controller sends
an alarm as normal. You can continue the power-off step
5.5 Power off steps
1. Click the OFF button on LCD or turn the off-on knob from ON to OFF;
2. Cut off DC SWITCH;
3. Cut off GRID switch and load switch
