Oh nice. I had to look both terms up (laminar air flow and CFD). Its good that you’re able to be thorough. I’m curious to learn the results of the CFD. Any idea what data he’ll feed it? Just object dimensions or can he give it assembly details like (for example) metal type/fastener type etc?

Nice job! Do you plan on putting some kind of wind baffles or deflectors around it? That seems like a lot of open space for drafts to have a potentially damaging effect.

Will's older videos may have been superseded by more current videos where he learned better ways of doing things. Keep this in mind and check the date/description of his videos. You may need to look for his newer videos on the topic.

Its possible for them to get out of balance at mid or low states of charge, but upon a full charge they will balance out at the top. The BMS will see them as 1 cell. The voltage on the parallel busbar will be sourced from both cells. 4s2p = 4 in serial (4s) x 2(p) of those connected in...

yes. It's called 2p. yes. b1+b2 in parallel = cell bb1. no, but that is the case with traditional lead acid batteries. No idea what I'm looking at here. Which terminals are positive, which negative? They will need to be paralleled and serialized right to properly share the load across the cells.

Can you elaborate? Seems to me like there should be some configurable delay rather than just flat slamming power over. I mean, unless it synchronizes waveforms...

Any more updates? Curious to hear the final result.

The purpose of a ground is to allow high current to flow so that in the event of a short, a breaker can trip. A ground conductor should be attached to something massive (literally, large mass) so that it can absorb and dissipate all that charge without becoming charged itself. Earth is the best...

search the word "contactor" here on the forum. You'll find what you need.

Spit is still recommended for corrosion prevention.

I surmised it had something to do with drainage and the potential for flooding.

Indeed. A good reason to start with an energy audit.

Assuming you're using the meter right and assuming it isnt capable of the low resistance measurement that should be that size copper conductor (whatever it is), I would venture to say its real copper. There's a thread on here by @RayfromTX where he determined some of his busbars were not copper...

Sounds like the large loads are the well pump, your compressor, and maybe the fans for the air conditioner. You need to know what the surge for starting each of these loads is. In my signature is a link to do an energy audit. It's just a spreadsheet for you to list each of your loads and to...

Ohm them out (check resistance). That should tell you every thing you need to know.
