Was the sky crystal clear or was it partly cloudy?

What is an

SOC as reported by the BMS in each battery. Charge the whole thing as configured to at least 55.6 volts to reset and coordinate the BMSs. Hmm... just noticed SA is not reporting pack voltage. You need to put a multimeter on the packs to determine a baseline.

No one HERE is saying that. Where exactly did you hear this "common" recommendation?

What are these? Never heard of them. Hang out on the forum and do lots of reading. Watch some of Will's videos. https://youtube.com/@WillProwse?si=bi8SSjUrv2Kj3RUb Watch some of Andy's videos. https://youtube.com/@OffGridGarageAustralia?si=r41lRbPs4rlJ_dqZ

Provided that they are all the same chemistry and the same nominal voltage, YES. Physics.

Looks great 😃.

I use 55.6 (13.9), 60 minute absorption, and 49 (12.25) as my operating voltage range. There is very little usable capacity outside this range

I have done something similar. Inclination matching latitude. 3 strings pointed 155⁰ and 3 strings pointed 205⁰. I sacrifice absolute peak power at 12: 20 p.m. ( my solar noon) for a wider production curve. The array wakes up earlier and lasts longer in the afternoon. All 6 strings to a 6 to 1...

Look at the name of this forum. D I Y = Do It Yourself. It seems to ME that you are asking on the wrong forum. You say you're designing a utility scale solar project but asking pretty basic foundational questions in your post. Do they have Google in India?

If if he was able to pull the wire from the crimp, the crimp was bad in the first instance.

Open the junction box. Carefully remove any potting material (like caulk). Unscrew the old crimp lug. Clean the mating surface. Cut back the cable end. Strip. Crimp new lug Wipe with isopropyl alcohol. Reattach with screw. You cannot reinsert a wire into a crimp lug. That will never ever work.

No, you don't have the settings set correctly. User error.

Mine does.

Will's 3k inverter is ~ $700. Weighs about 25 pounds. Sol Ark is ~$7000. Weighs about 200 pounds. So, I don't think it is remotely reasonable to expect anybody is trying to put Sol Ark capabilities into EG4 3k box. Probably not possible.
