sizing inverter
(OP)
Guys,
How do you determine the size of an inverter.
For example, if I have 220kW dc power, then can I use 225kW inverter??
Thanks for your reply.

RE: sizing inverter
BTW, battery power is expressed in ampere-hours and not watts/kW.

RE: sizing inverter
I agree with you. Batteries were not mentioned.
BTW, I still have to see photovoltaic systems without batteries for storing energy during sunny hours and discharging when the sun is out! I also said total efficiency as "reasonable" instead of "inverter plus battery".
You are right about your figures on inverter efficiency only, especially if your inverter is transformerless (as opposed to ferroresonant inverters).

It could also be so that he has a 220 kW DC motor and asks if that could be replaced by a 225 kW inverter plus induction motor.
I think that we need to know the real application before saying anything about this.
