What should we do with those inverters that are not use or storage for a long time?

Inverters that are not in use for a long time, require the capacitors to recharge first. Then inverter can connect to normal power.


The inverter will have capacitors in it. The electrolyte inside the capacitor will dry out over a long period of time without use. This situation causes a reduction in capacity and an increase in leakage. So do the following steps to recover the characteristics of the capacitor.

Storage time Recovery steps
Storage for less than 6 months Can directly connect to normal power supply
Storage for less than 12 months Connect to normal power supply for half an hour before running with load.
Storage between 1 year and 2 years Connect to normal power supply for an hour before running with load.
Storage between 2 year and 3 years Power supply with regulator
1.Power on for half an hour at 25% of rated voltage
2.Power on for half an hour at 50% of rated voltage
3.Power on for half an hour at 75% of rated voltage
4.Power on for half an hour at 100% of rated voltage
Storage for more than 3 years Power supply with regulator
1.Power on for two hours at 25% of rated voltage
2.Power on for two hours at 50% of rated voltage
3.Power on for two hours at 75% of rated voltage
4.Power on for two hours at 100% of rated voltage
