Signiture Solar dual 6000XP Kit setup.

[FilterGuy]

I have been helping a person that bought an eg4 'Kit' from Signature solar. He bought the kit but was unsure how to put it together so I have been helping him do a design for it. It occurs to me that others may be in the same boat so I decided to share the layout here.

The kit is this:

Complete Off-Grid Solar Kit EG4 6000XP | 12000W Output | 48V 120/240V Split Phase + 12800 Watts of Solar PV [KIT-E0009]

Explore energy independence with Off-Grid Solar Kits, EG4® 6000XP inverters. Choose components, batteries, and panels. Revolutionize your energy with EG4.

(The panels currently in his kit are different than what are currently being sold.... but that is to be expected. Panel availability changes daily.)

This is the high level layout:



A few notes:
1) Surge Protectors.

• The surge protectors are not part of the kit above. (He may have purchased them separately)
• The person is still figuring out the physical layout so we are still discussing where the DC surge Protectors should go. They will either be mounted on the inverters or on an external J Box.
• The AC surge protectors will almost certainly be mounted on the Breaker Box

2) Battery wiring and server-rack bus bars.
I tend to be a bit anal about balancing the load on the batteries. The following may be overkill.

• I have him flipping one of the bus bars over for easier diagonal wiring if he ever fills the 6 Slot rack.
• The wiring to the inverters are separate and each inverter has the opposite diagonal wiring of the other.
• The inverters are using the bus bar lug spots for the empty batteries. If he ever fills the rack he will need to adjust
  

The next few posts are worksheets for the design.

Looks great.
Should help many members.
One question... are the inverters and service panel in different buildings?
If not, I wouldn't spend the money on AC surge suppression. It doesn't hurt anything, that they are there. I just don't see any need for them. If any wiring leaves or enters the building, then definitely use them for those circuits. But circuits that stay in one building don't need them.

To tell the truth, I don't know if it is a separate building. He already has them, so we will get them installed.

He is high on a mountain in Montana so he is probably exposed to nearby lightning strikes. Given that, I would certainly not try to talk him out of it.
