[pvusers] Re: Question on inverting DC to AC

[Christopher Witmer <cdwitmer@spamcop.net>]

I'm trying to build a system for use in Eastern Japan, which is
50Hz/100VAC. Inverters designed specifically for the Japanese market are
more expensive than others, such as 60Hz/120VAC inverters, since the
Japanese market is small. If I could obtain a (relatively) cheap
inverter designed for the USA market and then get it modified for
50Hz/100VAC operation, that could be a viable solution for me. Does
anyone have any idea about how difficult it would be to make such a
modification to an existing inverter?

Thanks,

Christopher Witmer

with a bridge rectifier/capacitor circuit: a lot of inverter
manufacturers have entirely gotten away from using big transformers.
