is delivered.
No charging operation is required.
1 to 2 years
The inverter
needs to be powered on for 1 hour before the
first running command.
2 to 3 years
Use a voltage-controlled power supply to charge the
inverter:
Charge the inverter at 25%
of the rated voltage for 30
minutes, and then charge it at 50% of the rated voltage for
30 minutes, at 75% for another 30 minutes, and finally
charge it at 100% of the rated voltage for 30 minutes.

Use a voltage-controlled power supply t
inverter:
Charge the inverter
at 25% of the rated voltage for 2 hours,
and then charge it at 50% of the rated voltage for 2 hours, at
75% for another 2 hours, and finally charge it at 100% of the
rated voltage for 2 hours.
The method of using power surge to charge for the inverter:
The right selection of power surge depends on the supply power of the inverter. Single phase
230V AC/2A power surge applied to the inverter with single/three-phase 230V AC as its input
voltage. The inverter with single/three-phase 230V AC as its input voltage can apply Single
phase 230V AC/2A power surge (L+ to R and N to S or T). All DC bus capacitors charge at the
same time because there is one rectifier.
High-voltage inverter needs enough voltage (for example, 400V) during charging. The small
capacitor power (2A is enough) can be used because the capacitor normally does not need
current when charging.
6.1.3.2 Electrolytic capacitor replacement
Read and follow the instructions in Chapter 1 "Safety Precautions
".
Ignoring the instructions may cause physical injury or death, or damage to
The electrolytic capacitor of the inverter must be replaced if it has been used for more than
35,000 hours. For details about the replacement, contact the local IMO office or dial our
national service hotline (400-700-9997).
