Hello Everyone,

Mi name is Maxi. I'm from Argentina. I'm starting to plan my rv solar system.

For now I only use a battery wich I previously charge to use the lights mainly.

I'm learning a lot from the forum.

I've started reading the main stickys by sunking and other people's post, and made the next calculations:

following post "solar off-grid battery design"

4 led lights 12 watts x 5 hours = 240 watts

1 water pump 90 watts x 2 hours = 180 watts

3 cell phones 10 watts x 2 hours = 60 watts

1 LCD TV 50 watts x 3 hours = 150 watts

1 directv deco 50 watts x 2 hours = 100 watts

1 notebook 60 watts x 3 hours= 180 watts

total in a day 910 watts x 1,5 factor= 1365 watts in a day (1400 to round up)

Hours of insolation 5

Size of array: 1400/5= 280... round up 300

battery capacity 341 amp (3 day reserve)

Charge size: 25 amp (30 mppt regulator)

I will also have a generator to charge full twice a week batteries.

Thank you for checking my numbers.
