Before you purchase a power inverter, you'll need to work out the wattage of the appliances you wish to power. A Wattage (W) rating is the measurement of power that an appliance will draw while in use. An appliance's wattage rating is usually indicated on the product label or in the manual. If you're struggling to find this information, you can either search online or use a power meter to physically measure the appliances consumption.
If you are looking for more details, kindly visit Senergy.
If you only want to power a single appliance, then you've got all the information necessary to size a power inverter.
Should you want to run more than 1 appliance, then we will have to do a very small caclulation.
This involves adding together the wattage ratings from all of the appliances that you want to run simultaneously. This will give you the maximum power draw (W) that you'll ever need to pull from your power inverter at any given time.
It's recommended to add a safety margin of 20% to 30% to the total wattage to ensure that the inverter can handle any sudden spikes in power consumption. This is the figure that you will use to size your power inverter.

recharging the batteries"? So much of the time folks seem to forget the batteries need to be recharged If left at a partial charge level it really reduces the life of the battery. More on that farther down.
Using a two slice toaster will use some of your battery capacity. The inverter should not have a problem powering the toaster.
However, now that you used some of your battery, then tomorrow you use more, pretty soon you are down to 50% or maybe 80% discharged. Especially if you ran your furnace quite a bit because it was cold outside. [If you have 200 watts of solar (better yet 300 watts) and have good sunshine for 6 hours of mid day, you are good to go.]
Running a battery down to 50% cuts the life of a battery in half compared to only using 25% of the capacity, Go down to 80% discharged and you get 1/4 to 1/3 the life of the battery. Trojan has a life cycle chart for their deep cycle batteries. Use 25% of the battery and you get about discharge/charge cycles. Use 50% and you get about cycles. Us 75-80% and you get around 700 cycles. With a marine/deep cycle battery the figures are probably more like //500 respectively for the 25%/50%/80%.
Additionally if you don't get your batteries back up to 100% every 4-7 days you reduce the life of your batteries significantly. If you run your batteries down to 50% and recharge with the generator you are looking at 8-10 hours to get the batteries back to 100%. The reason is the last 15% of the charge goes really slow. The charge amps typically drop to 5 or 6 at the 85% full level, dropping to 3 or so at 10% and going on down to 2 and lower as you approach 100%.
You can use the voltage level of your battery as a guesstimate as to the level of charge. However if the batteries had a significant load on them (toaster) the batteries needs to be left at a no load level for 15-30 minutes to stabilize. No load means only about 2-3 amps of discharge. If you ran your generator or connected to shore power you batteries will get a surface charge. If the batteries have been charged, either let them sit for a couple of hours, or turn on 1 or 2 incandescent light bulbs for 30 minutes to an hour and then check the voltage.
If you are going to do quite a bit of dry camping or boondocking you need to install a battery monitor, such as a Trimetric which tracks the number of amp hours (AH) being discharged and when being charged. It also shows an accurate percentage of the state of charge of the battery.

A major concern that no one seemed to address is: "How are youthe batteries"?
