A toaster and a coffee maker? Off an inverter? WHY WOULD YOU DO THAT????

There are things that the stove does very well, and uses no electricity.

I don't care if it works, it's... not efficient use of your batteries.

I have a 33 ft sailboat with 2 house batteries on the usual 1-2-both

independent ans makes sure that I can always start the engine even if
the house batteries are empty.
I installed a 1500 W (2000 peak) sine wave inverter which I bought for
less t6han $150. This runs the TV, VCR, Microwave, toaster,
coffeemaker etc. I can only run one of these items at a time. I have
had no problems with the modified sine wave
But the toaster uses 1200 Watt. At 12 volts this is more than 100
amps. So I used No 2 wire to connect the inverter to the switch. I
soldered the connetions to make sure. I always use both house
batteries because drawing 100 Amps from one battery is very high. The
110 V side of the inverter is connected to via a selector switch to
the 110V system on the boat so that all the outlets are live. The
selectro switch makes sure that the 110 V system on board is fed from
the inverter or the shore power, but not both.

The toaster and the coffemaker only runs maybe 15 minutes per
breakfast. So the usage is only 100*15/60=25 amp hours. My batteries
are 100 amp hours each so this is no problem. I have 3 ways to
recharge the batteries. One is by solar panel. When I leave the boat
after a weekend the solar panel will recharge the batteries during the
time I am away. This is what usually happens.The second is when I run
under engine, then I have a switch which parallels the house battery
to the starter battery so that the alternator recharges both the
strater battery and the house batteries. The third is with a battery
charger from shore power.

With this system I have lots of power for everything, but of course I
cannot have a hair dryer, fridge or heater except when I am on shore
power.
