3.8. Capacitor reforming Guide after long storage
For correct performance of this product after long storage before use it is important that Inverter Capacitors are
reformed according to the guide below:
Storage time Procedure to re-apply voltage
≤1 year Apply rated voltage (1) of inverter in the normal way
Between 1-2 years Apply rated voltage of inverter to the product for one hour
≥2 years Use a variable AC power supply to
1. Connecting 25% of inverter rated voltage for 30 minutes.
2. Connecting 50% of inverter rated voltage for 30 minutes.
3. Connecting 75% of inverter rated voltage for 30 minutes.
4. Connecting 100% of inverter rated voltage for 210 minutes.
Once the procedures completed, inverter just can be used normally.
(1): Please refer the rated voltage according to model label of inverter.
