How to change 480v photovoltaic inverter to 380v [PDF]

6 FAQs about [How to change 480v photovoltaic inverter to 380v]

What happens if you convert 380V to 60Hz?

If however you transform down to 380V, that is now 380V 60Hz, so the V/Hz ratio is now 6.33:1, well OUTSIDE of the tolerance band of the motor design! Your motors will have a loss of peak torque equal to about 30% of rated torque, so they will work harder, draw more current and over heat.

How much torque does a 380V 50Hz motor produce?

A motor creates torque based on the voltage and frequency ratio, and as long as you are within 10% you are fine. A motor designed for 380V 50Hz has a V/Hz ratio of 7.6:1 (380/50) and a motor designed for 460V 60 Hz has a ratio of 7.67:1, virtually identical (not a coincidence by the way).

How to turn on a PV inverter?

Make sure the DC open circuit voltage of input strings is less than 1000V. ) Turn on the AC circuit breaker. ) Turn on the DC circuit breaker. (Skip these two steps if there are no circuit breakers.) ) Switch the DC Switch to the “ON” position. When the energy supplied by the PV array is sufficient, the LED of inverter will light up.

How many inverters per phase?

1. With up to three 7 kVA inverters per phase, the 3-phase system sizes are 21, 42 or 64 kVA. In the example in Figure 2 with a 60 kVA source and load, there is approximately 87 Aac per phase. This means that at least two inverters per phase would be required as each inverter can pass through up to 50 amps.

Can a 480V VFD feed a 50Hz motor?

You can feed a VFD with 480V and program it to only deliver 380V output max. at 50Hz, that way it will deliver what the motor wants and you will be getting full HP at design speed. The other side issue is your control voltage.

How many volts does a 480 volt transformer produce?

Not open for further replies. 480 volt three phase down to 380 volt three phase. Transformers of this rating usually have a long lead time. secondary? With 480 on the primary, the secondary should produce 384 volts.
