Scotty I need more power!

The only way to cut generator recharge runtime. While still using the same amphrs of power is to use a bigger charger/converter that can supply more amps up to max amount the batteries can absorb , replacing 200ampHrs with 270Ahrs, might allow you that third night with heat, but it is Not going to shorten your generator runtime, replenishing the planned for battery ,
capacity , replacing what was used the night before, will require the same amount of time. Unless a stronger charge system is used
I'm assuming that you think that with a 70 amphrs increase, you have a buffer where you can run the generator less and not go back to full charge on Day #2 and #3, and still have n enough battery power for heat on night #3,
You have not provided info to show this is possible,
How many amphrs is used overnight, how many amphrs will a 2 hour or 3 hour charge return to the batteries,
Do you have a battery power monitor that will track battery capacity , track power out and back in , show you the "state of charge percentage" , the amphrs remaining in your batteries

Let me ask you a question. I have the Victron SmartShunt installed now. My onboard converter seems to be supplying about 17 amps to the batteries when either plugged in or with the generator on. I also have the Victron DC to DC system installed so when the engine is running I’m getting 27 amps. With the engine and generator both running I’m getting over 40 amps. So the main problem seems to be with the converter. Instead of upgrading that, can I get a lithium battery charger that I can plug into a 120 outlet and hook directly to the battery so it charges the battery too when the generator is running? That won’t feed back into the converter will it and damage the converter? I see Victron has a 20 amp plug in charger and if I could use that and get 37 amps to the batteries with the generator running that could also cut my generator run time way down.
