Hi there, newbie here. Looking through the forum over the last week or two has been great, thanks for all the info!
Looking for an assist putting together a solar charger for a lift-tech 12/24 DC boat hoist motor. I ran some numbers, not sure I got it right though. any advice on controller, panel or battery is greatly appreciated!
Based on some looking around:
motor: 40-80 amps
lift/lower time: 3 minutes per cycle (boat @ 5000 lbs on vertical hoist which slightly larger than mine at 3400 lbs)
assuming average load of 60 AMPs
usage: 2x per day on weekends, on occasion during week
battery:
AutoCraft Marine Battery, Group Size 24M, 800A CCA I use for the winch on my trailer when needed. its advertised as a marine deep cycle but I can't find an amp hour rating
RC: 135 minutes
solar system:
Genasun GV-4 50W 4A Solar Charge Controller with MPPT
ALEKO SP40W12V 40 Watt 12 Volt Monocrystalline Solar Panel
- Operating voltage: 17.5 volts; Open circuit voltage: 22 volts
- Operating current: 2.29 amps; Diode bypass: 1*10 amps
assume 90 amp hours on the battery (no idea if that is right)
motor: 60 amps / 60 minutes = 1 amp/min * 3 minutes/cycle = 3 amps * 4 cycles per weekend = 12 amps
battery: 90 amp hours * 20% = 18 amps available to stay above 80% used
if that is right them I can run the hoist 4 times with no sun and stay above 80% depletion.
to recharge:
2.29 amps from panel * 80% for loss = 1.8
12 amps depleted / 1.8 = 6.7 hours to charge
any help is greatly appreciated!
