Need your help/ an estimate.
I'm considering an inversores to run any and all items in the following apartment (approximately 1200 square feet); 5 a/c's (one in each bedroom-3, one in service room, one in living room/kitchen area , refrigerator, 2 tv's, cable, phone, dvd player, radio, 2 ceiling fans. About what cost am I looking at? Thanks!
This is not a wise way to go.
Unless you're going to be using teenie weenie super efficient AC's, the purchase costs, wear & tear on the equipment, (specially batteries) and the high operating costs are prohibitive.
Assuming that all is well in paradise and that the city power is a full 110 volts plus, you would lose 20% power while on inverter and the same recharging.
As an example, I have an AC unit here that draws 7 amps when cruising.
If you have 5 of those plus your other equipment, your draw would be approx. 40 amps.
Assuming you have frequent power failures as is mostly the case in the DR, you would be wasting a constant 8 amps (20% of 40 amps), which is the equivalent to the consumption of 45 efficiency light bulbs, or like running 4 hair dryers 24 hours per day.
In real life, your losses will be even greater, as there is a presumption of new equipment, and even if yours is going to be all new, it won't stay new for long.
Your situation calls for a generator.
What would you do after the batteries run out?
With that type of consumption, you'd probably only get 4 hours out of 24 batteries, from a full charge.
The best scenario is to have an inverter, approx. double the capacity of your typical consumption, and have it running everything except the high amperage devices, (like AC's, hot water tanks, pumps) and have a generator that has the capacity to run it all, plus charge the batteries.
