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.
