[RE-wrenches] 40+KW off grid - Suggestions

[Doug Pratt]

Yes, the 100kW Satcon battery-based inverter has shown up on their website, but when we inquired about availability it appears they haven't built one yet and are fishing for someone desperate enough to cough up the $100k plus price tag. So, buyer beware. This is a 1st generation product with little track record beyond the lab, and the first few are going to pay the R&D bill apparently. 

Just for the record, I'm enthusiastic about the other new SatCon inverters. They're efficient, and logically laid out for easy connection in the field.

Cheers,

Hello All,

I have an inquiry for a 40KW+ off grid and are looking for suggestions.
Small conference center, some lodging, commercial kitchen, 30+% full [loaded
up] occupancy, small staff and maintenance crew for [70%] balance of the
time.

The full loads will probably be met with [1 or 2] LP gas generators.
The utility line quote is $1+ million away.

We are looking at all options-

High volt runs  to AC coupled and Outback 3648, 6 packs.

High volt to FM 80's and Outback 3648 , 6 packs.

Sunny boy Islands 5048's.

We want some redundancy but are looking for a good blend of large, reliable,
and redundant.

I welcome your opinions.

Thanks in advance,
