I am trying to put a semi portable power solution in a 6x12 enclosed trailer. I want to keep the battery internal to the trailer and have moveable solar panel so I can park the trailer under the shade and keep solar power coming in. I will be operating it between March and October each year.
My insolaration is 3.5-4hrs during those months in Oregon.
Here is the setup I am thinking...
2 Panel foldable solar panel
Max Power: 240W
Max Power Voltage: 18V
Max Power Current: 13.33A
Open-Circuit Voltage: 21V
Short-Circuit Current: 14.65A
Solar Cell: Mono
Folded Dimension: 149 x 67 x 7.4cm
25A 300w MPPT solar charge controller regulator 12V LCD wider MPPT input
Upg 45964 UB-8D AGM Sealed Lead Acid Battery 120Ah
Primary function to run LED lights for nighttime use.
10 hrs at 12 watts nighttime exterior trailer lights =12 amps per day
10 hrs at 6 watts nighttime internal trailer lights =6 amps per day
Charging misc 12v camera batteries during the day
Possibly a laptop in the afternoon for an hour or two.
I was thinking I would get about 3.5 hrs of 8Amps per charging day
which would give me 24amp replacement power on a good day. If not, the 18amp draw each day would still last me till I went home on Sunday where I could recharge from solar or a trickle charger at home.
This will usually be for camping Friday-Sunday. I will have a trickle charger top the battery before travelling to site.
This setup will only be used 5-10 times during the summer and then battery will be removed and stored in garage.
