Soldered connection is better than crimped. But if both connections are properly made, the difference isn't enough to matter. The only variable is vibration. Soldered is not recommended in a high vibration situation.

I didn't extend my leads. I planned for the BMS to be next to the battery negative and the breaker to be next to the BMS.

Shrink tubing is fine. But you should either cut that bolt shorter or replace it with a shorter one first.

Correct

You should have asked Signature Solar if they were an approved vendor.

I used to think this, too. But actually they are the same. (Just more paranoid)

Two options 1. The battery is defective and won't accept a charge. Or 2. You're using all produced power during the day, and nothing is left to charge the battery.

There's nothing wrong with soldered connections as long as they are good clean connections. (Everything on every circuit board is soldered) And the 7 AWG silicone insulated conductors are more than capable of handling 100a each, at that short length.

Either is fine, but the service panel is the simpler option. As it's already designed to accommodate more connections.

That's over my head. I'm just a simple man, who prefers to keep my projects simple. I avoid electronics whenever possible. I can do anything I need with simple relay logic.

Thanks But I'm only interested in the 5000's.

They are expensive. Around $2k. It would be cheaper to buy 3 single phase chargers.

The SCC will never see short circuit current, unless it shorts internally. Which means that the SCC has already failed.

Yes No OCP is required. But it is recommended to have a disconnect near the SCC for service.

That table is for the current carrying conductors. Use this for the EGC. #10 is still correct, for that low of OCP. Just giving you the correct table.
