[QUOTE="condor22, post: 619809, member: 1932"] A small 700W microwave will use around 1100W of input power a larger 1200W will use between 1800-1900W. Using worst case of 1200W (small 750W oven) this equates to around 120 amps from an AGM battery thru an inverter. (divide load wattage by 10 as inverters are inefficient.) Therefore for each 6 minutes (1/10 of an hour) of use of a microwave, you will use 1/10th of 120 AH = 12 AH. Pulling 120 amps from a 130 AH battery is not going to do it a lot of good as it's very close to 1C, so check the C rating of your battery. My advice to anyone using an inverter is, have a battery bank that will run it at no more than 0.5C, which for a 120 amp load is 240 AH. Then keep in mind, what you use you need to replace. This needs adding to other use i.e. lights, TV, pump, heater etc. Which in turn may need double the solar. :) [/QUOTE]
