I really don't understand what your problem with this arrangement is.<div>How would this be different from a house on phase A-B installing an inverter and the next house on Phase B-C installing an inverter? Or, installing two single phase 240V A/C units in a three phase building? Electricians have no issue with installing single phase equipment in three phase buildings so why should small inverters be any more a problem.<div>
While it is always neat to install three inverters n a three phase configuration, 4,500 watts of imbalance is trivial.</div></div><div class="gmail_extra"><br><br><div class="gmail_quote">On Tue, Nov 27, 2012 at 3:59 PM, <span dir="ltr"><<a href="mailto:holtek@sbcglobal.net" target="_blank">holtek@sbcglobal.net</a>></span> wrote:<br>

<div>We were asked to inspect a GT system installed by others. Service is
208 3ph with two (?)Fronius IG 4500 208v inverters. The inverter panel is
3ph with two 2pole breakers - one each side of the buss bar in a A/B, B/C
configuration (??). Called Fronius and they said it would work, but they "don't
recommend it". No other information was given as to why they don't. My
electrician is very uncomfortable with doing work on this system as is (ME
TOO!), so I am wondering if I might be able get some ammo to convince system
owner to add a third inverter to get the system right. What problems might/will
be encountered in this system if not modified? BTW - inverter LCD screens were
crapped out, so we couldn't readily see if system was functioning
properly....from metering, we think not.</div>
