Overnight on the hook?

Most large cruisers run their generators 24/7 when away from the dock. Same with my boat except when the outside temperature is pleasant we will open up the boat at night and shut down the generator. So, for example, in the nice little cove at Alans-Pensacola in the Abaco which is sailboat haven we anchor away if boats are there so the generator can run to it's heart content; that's common courtesy. The 52DB generators are very quiet but on a still night when you can hear the fish jumping and the shrimp clicking under the boat the generator can be heard across the water. If we are the first to a remote anchorage and another boat pulls in they will have to put up with us (Metallica and all); that's just the cruising rules from my perspective.
Now with all that said - as an edit - we make an effort to meet fellow boaters in the remote anchorages and invite them to our air conditioned boat for cocktails and snacks - the folks in the smaller sail boats really appreciate the relative luxury break. I still hear from some of them even seven years later...

Interesting how everyone turns off generator. We do a lot of overnight on the hook and I leave the generator on all night. I have heat/AC I don't worry about opening the fridge or freezer. The generator is capable of running for thousands of hours, why not use it. We have almost 4000 hours on ours. Is it because you all are gasser? I used to have a 340 and we ran that as well. Run it and sleep well.

When I had my 340, I use to worry about all of what is being discussed here. But since I went all diesel, I am with you @mquiet and once I leave the dock the generator runs until I am at another dock. That said we stay on the hook for days at a time, all of the time. Especially these days. I put in a lot of work getting this boat to have all of the comforts of home and not have to rough it in any way and if that means not turning the generator off, then so be it and lifes all good.
 
currently I’ve got these modules on each battery bank:

And then there’s an app that goes with them so the voltage is displayed in my phone. Voltage readings are spot on and I use that to calculate how much juice is left approx. I’d like to install something more robust like Shoyrtt’s setup there.

App looks like this:

M prod. How are you connecting these to a bank with one or more batteries? My setup has one starboard batterty and then 2 for the port "bank" with a positive cable coming from each battery and then the negative terminals connected together. Which positive and which negative terminal do you choose when connecting the monitor? Or does it matter?
