I'd say, on average the consumption will be 600W, but can go up to 1100.
I only have a small balcony, so not sure how much solar panel can help in this case?
I prefer nuclearcat approach with batteries, even if it's gonna take several hours to recharge, but not sure how many batteries would I need and where to buy an APS from?
My APS is 1200va but realistically speaking, my inverter gives me a max of ~4.3 amps in capacity (max of 960watts).
The problem is that most 1200va APS (which I think is the size you need) are 12 volts, meaning that they are to be connected to one 12v battery (preferably, but you can connect 2 batteries in parallel but it will be a bit heavy on the charger).
Let's assume you got the 220AH tubular battery (lives longer than "kamyon" flat lead-acid battery), here's the max you can get out of it for an average of 600W consumption:
220ah x 12v x 85% (invertion rate) x 70% (maximum healthy depletion rate) = 1570W.
1570 / 600 = 2.6 Hours (only when the battery is in a new stage)
If you want double this time (5.2 hours):
I- You either install 2 batteries in parallel (on a 1200VA APS) (but it is extremely important that the batteries are both new):
Pros: lower cost APS, the charger does not consume much from your generator subscription
Cons: Long charging time (up to 9 hours I assume)
Cost (approx): ~180$ + 2 x 250$ = 680$
II - Get a 24v APS, (1800VA and above) (to connect to 2 batteries in series)
Pros: It gives you more amps (6.5 and above) if you need to use it on devices (fridge or hairdryer), less charging time: 5 hours
Cons: APS is more expensive, the charger takes more amps from your generator subscription
Cost (approx): ~300$ + 2 x 250$ = 800$
Location: I can refer the place that I got mine from, but he doesn't have tubular batteries AFAIK
P.S. If you are rich, go for the lithium batteries, they damage less when full depletion, they charge faster, they last a minimum of 10 years.
