Efficiently Combining Commercial Inverters

[ryangittens]

What's the most efficient way to combine multiple inverters when there are only a few?

On a 277/480V 3PH project, is there a less expensive way to combine just 2 inverters with something other than a $6000 42 space load center? How do you guys do it?

where you getting that pricing on a panelboard? Ive been paying like $1700 for a 54 space full of breakers. An 18 space interior is like $275, and a can and trim is like another $3-400. Breakers like $150 without even shopping around:

And just to be complete, here is a 3R can/trim. Don't quote me on whether this is the correct size for that interior I posted previously, just giving you some examples

This is great. I've been looking at the assembled enclosures 400A 277/280v and those were the prices I saw.
