That’s the simple part, anything close to sidereal rate is fine. But at the end of the day (which changes continually), it needs to reverse back to face east and wait until the sun is perpendicular to the panel surface (how calculated/determined?) and then resume tracking. Not impossible but...

Um, those panels have: Open Circuit Voltage (VOC): 98.7 V If you have 2 in series directly connected to your batteries would be bad. There has to be an SCC. Have any pics?

What SCC do you have now? If your SCC cannot handle 5S voltage, just get a second SCC like a Victron, smallest that does 48V. Get the Smart type with Bluetooth. If you plan on expanding later, get a bigger one.

If it were me, i'd charge them both completely full with good long absorb. Then put them into service and see how they behave before buying something you might need. If they get out of balance, you could always charge them individually. Maybe this is a yearly task you are ok with? If its...

Conjuring @Will Prowse

Probably around 2000Wh per day. Thats 84W at 33% duty cycle (20 mins per hour).

It’s easy to test. Disconnect solar (asap!) and connect the battery. If it powers up and displays in app you are good. If it prompts for firmware updates, do them right away. Just a button press and usually less than a minute (awesomeness).

What is the "unit"? Is the battery full? Are the panels in series and partially shaded? Happen to have any pics?

200Ah / 200A = 1h 200Ah / 100A = 2h 200Ah / 50A = 4h

Hmm, i don't see why they should be the same. I have cutting board sheets between to prevent conduction between cells. I have cement board below because it is fireproof and sits on a 2x12 shelf.

Wait wut? What's the problem with sitting on cement board?

What is the Voc of your panels and how do you expect to wire them? (3S2P or 2S3P?)

What was the event that caused the fuse to blow initially? That looks like 275A and there are a few batteries connected to a bus bar that "looks" a little small for what should be a 1000A bus bar.

2S3P has a different meaning. As for what you have i'd say 2S in parallel with 2P.

I should have remembered that. Fun fact: -40C = -40F (= 233K for completeness).
