There is however another issue of just charging your batteries from the 50% charge to the 90% charge. You can do this charge state cycle for 12-14 times without doing damage to the batteries. After that you need to do a 100% charge state which will take the 12 hours or so of running the generator. Once you get a good 100% charge state then you can go back and start doing the 50%-90% charge state cycles again...
And like you I would do this at home where I have shore power available and have no need to rely on the genset. Expecting to achieve 100% SOC using the genset as source power just isn't practical.
