The short answer is yes, with reservations.
Take the worst case you mention, the microwave oven.
Here I assume a 240 Volt supply from the inverter, if 110V the situation is even worse.
I’ll also assume the microwave consumes (say) 750 Watts of power.
I also have to assume a 12 Volt battery.
Disregarding losses all through, it goes like this:
Your battery capacity is 85 Ah.
The microwave will need 3.125 Amperes at 240V. for full power.
Thus the battery will need to supply 20 x 3.125 or 62.5 Amperes.
Thus the battery, without further charging, would run the microwave for 1.36 Hours only.
Your solar cell supplies 80W., and if the voltage is 12, the max. current it will supply the battery is 6.6 Amperes. It would take 12 hours (plus) to fully charge the battery (it would/ should never be flattened).
So the reservation is how much charge time is available, and how much you wish to use high- draw appliances.
A careful selection of a TV set could give you plenty of viewing time, however!
I think you’re really stretching that 1x80w panel. It would probably take a long time to charge that battery and keep it charged with any kind of load drawing on it. I think it would be fine for a couple flourescent light bulbs for 6-8 hours.
80 watts?
Volts X Amps is Watts.
If you need 120 volts to run something, and you have 80 watts:
120 X amps = 80
amps = 80/120 = 1.5 amps
You have a concept of a 100 watt light bulb? 1 – 100watt light bulb need about .8 amps. Your solar panel will light 2 – 100watt light bulbs. Forget about running a microwave – you need about 15 amps for that.
