Hello wrenches, We have an opportunity to install a very large (60 kw) off grid system in Mexico. It is currently three phase. I do have the option of changing out the air conditioners (36 of them) to 120 single phase, but it is an added layer of complexity/cost that it would be nice to avoid. The largest off grid system I've done is 21 kw so far, and it was single phase and fairly straightforward. Does anyone know of a three phase, off grid inverter than can be paralleled for 500 (possibly 450) amps oputput. I am currently dealing with three 120 volt lines (2/0) and a neutral, running to a transformer to "clean up" the power from the gennie a bit. The client is determined to do this as he has spent about $500,000.00 USD in diesel over the last 5 years.I would very much like to get that transformer out of the picture... I am well versed in the complexities/pitfalls of battery systems this large. I'm planning on using the Surrette YS-31series to minimize the footprint, as well as use Water Miser caps and install three separate deionizing water systems. My issue is the inverters. I have seen a Korean inverter, Sunsine (http://www.dongeiecos.com/) that is capable of this, but I am not sure I want my first install of this inverter to be 3000 miles away.... Anyone?
