For setting up solar charging for boat only after use when its done for the day. Would it be required to have bmv for SOC or does that mainly help with charging and discharging at the same time? The solar setup is on the boat shed not on the boat.

Solar charging, SOC required for boat?
if you wanted the SOC to work then the BMV would have to be on the boats electrical systems you can then see the battery status at all times.
Hi BT. Welcome.
SOC is one of those things you might either love, hate, distrust, don't care, or be misdirected by.
It's a calculated figure, and in your case likely totally irrelevant to controlling your charge needs. To have it you'd need a BMV well-tuned onboard.
With Li or exotic batts there may be value, but if just Pb's it's really just an 'extra' for the geekish. :)
Popped in to say that I went through all of those feelings for SOC!
Unless you've got a particular use case in mind, I'm not sure whether you absolutely need to measure the SOC. The charger will work irrespective of whether you have a BMV or not - if the charger is dialled in correctly, it doesn't need a BMV to tell it that the battery is full.
