Re: [RE-wrenches] largest 240v GT inverter

2020-02-10 Thread Dave Angelini Offgrid Solar 


Definitely far easier with less strings and BOS for 1000 vdc. I have
been begging for a 1000 vdc charge controller for offgrid!

 520-270-4873 HI All,


I'm wondering what the largest GT battery less inverter (and what people
recommend) for 240v 60hz is out there.

 I don't need MLPE, as project
would be ground mount, its large residential, potentially 60KW. 

 SE has
their 11.4KW, but I've heard lots of bad things about them recently. 

Fronius has a 10KW?

 Thanks in advance

Here are a few answers to ( thanks) the comments.

1. its already has a 400 amp 240v service, I don’t see that changing, loads are 
 not going up, they just want to add solar.

2. I would rather do 4 Primo 15’s at 1000v than, 8 SMA 7.7 at 600v, unless 
someone can convince me otherwise.

This project is still just in the talking stages, and is months out before

Re: [RE-wrenches] largest 240v GT inverter

2020-02-09 Thread Jeff Clearwater 

Hey Jay,

Why not just use 8 SMA SB 7.7's = 61.6 KW rated, 32 Amps 240 each.

Then use a dedicated 320 Amp Rated (Typical nominal bus of a 400 A 
panel) Supply Side fed Breaker panel as you'll have 256 x 1.25 Amps of 
Solar bus = 320 - right at the limit but you are good to go!
