Happy 4th to all. 

I'm thinking of installing a 10,000 watt inverter on my B40 and curious to what others may suggest size-wise on an inverter. Overkill perhaps? The goal is to have the ac outlets hot for fans and chargers at anchor as well as toaster oven and microwave. The eventual television and boosted antenna. Absolutely no thought of using the air conditioning nor water heater.

Any thoughts or suggestions?

Thanks,  Wayne

You will want no more than a 2000 watt inverter. My B-40 came with an 1800 watt inverter and that was more than enough to run everything you mentioned. . The toaster and microwave can not be run simultaneously and we always ran the engine with the heavy amperage appliances.Your TV and antenna will draw about 5-7 amps based on its size. The toaster and microwave are about 1200-1500 watts and will quickly discharge your battery, if you do not run your engine at 1800 rpm to keep the battery charged. Fans, charging electronics are minimal. 

Forget about air conditioning unless you add a generator. Also, an inverter draws from the battery. You can't use it to charge the battery using the battery charger. You create a circle of electricity and the overhead of the inverter just continues to discharge the battery. Make sure you get a pure sign inverter or some of your appliances and chargers may not work.

If you are interested in installing a generator, I can help you with that as I installed a NextGen 5.5 kw genset in the cockpit locker of my previous B-40.

Thanks for the input guys as it will save some money with a smaller inverter. I had looked at specs on the NextGen 5.5 but unsure if we'd be happy with the humming. However, we've not ruled it out provided I can get away from the rat race to install myself. 

Guess I could use the Honda 2000ie I have but rather not deal with having to lift it in and out of the locker and storing mogas onboard.
