[RE-wrenches] 30 kW Inverters

[Peter Parrish]

Can't, that's why we need 2ea inverters with 50 kW on the roof. 25 kW on
each of the two inverters.

"we have to split the AC output into two separate services."

 

How can this be done with a single inverter?

We haven't designed/installed a 30 kW-dc class system for some time now
(last time we used a Xantrex PV 30) and are currently investigating what is
available in terms of single inverters with 240V 3Ph output. Our customer
has enough roof space to for 58 kWp of modules, but we have to split the AC
output into two separate services. So the first thing I've noticed is that
there are not many inverters in the 30 kW range: Satcon PowerGate 30,
Xantrex GT30 and by comparison a Sunny Tower with 6ea 6 kW SB inverters.

 

We will be feeding 240 3P so the GT30 and ST will need transformers.

 

So, I'm inclined to look more carefully into the PowerGate 30, first.

 

I am looking for some feedback from folks who have recently installed 30 kW
inverters. If this is contained in an archived thread, please direct me
appropriately.
