Thought I had posted the following yesterday. Mystery so here I go again.

Greetings to the forum.
Status- our craft has a 1800 watt inverter our house battery bank is two 27 opium batteries, our alternator is 90 amp Delco. Our draw at any one time is a small coffee pot, a toaster, and the 110 fridge, and a 750 watt micro. Outside of the fridge demand, there is only one of the mentioned appliances in play at a given time.
Picture- Underway, fridge on the inverter, the coffee pot is utilized. The initial pull on the inverter has the amp gage pulling over 70 amps during the boil and then it settles back to normal following the cook. Same for the toaster.
question- What is the effect on the alternator peaking out at 70 amp off and on as the demand shows? In my mind, the demand through the inverter converting 12 volt to 110 cause the alternator to react and recharge the battery. Is this high amp delivery hard on the alternator. Should I be concerned?
I read here and there on the forum of requiring 140 amp alternators or running separate alternators to supplement usage. I would like to think our demands are minute enough to not cause alarm in the applications given. We do have a 2000 Honda and use it when we are off the engine and use of these appliances are employed over drawing down the batteries while on the hook and engine off.
