Newbie..... Batteries?

[philo111]

I am desperate to be able to run a 1000 watt Microwave oven for a total of 15 minutes before needing to recharge the golf cart batteries. The inverter is 2000 Watts.

How many 6 volt batteries will I need?

THANKS!!

I can't imagine that you will ever be able to do that successfully with any reasonably sized RV battery bank. The inverter size is "OK" but your microwave may use at least half of that and if the inverter is not a True/Pure Sine Wave (TSW, PSW) it's possible you would burn up the microwave even if the battery bank was large enough.
This is not a realistic goal and you should be looking at other power sources when using the microwave for such a long period of time.

i have a decent size 5 battery AGM bank, 675 Amhrs , thats equal to 6 or more golf cart batteries, these weight 102# EACH

and i still prefer to run the generator, 6 minutes to bake a potato

i might give it a 1 minute shot late at night, so as not to disturb anybody
15 minutes MW on batteries never, well maybe if i had a 2000 ampHr bank of batteries

in lead acid that about (1) ton aka 2000# of batteries

if you need 15 minutes at 2 AM, try eight batteries
if this is during daylight normal hours, save the batteries, use the generator

you would need several hours of generator run time with a Beefy converter, for a recharge anyways, better to use the generator for minutes instead of several hours

BTW we full time and have a residential 120v compressor fridge and a large MW
i know about heavy amps and battery recharging

been there tried that
just a 6min potato is a really hard battery drain

15 minutes continuous? You probably can't carry that many batteries. Usage divided up into 1-2 minute increments? 6.

Probably at least 4 to be safe.
I would run a generator instead.
