DIY Solar Shack
You can run most anything on batteries. Just need to know how much power is needed and match it with amp-hours.
FRIDGES ARE TRICKY ...
Like all appliances with compressors inside fridges have motors which start and stop. Motors have surge current when starting which pulls 3 times more than normal.
Let's Get Into It
BEST TO TAKE AN AVERAGE
The average refrigerator uses about 350kWh per year.
GET READY FOR THIS ...
A 10 year old fridge will probably take twice as much power as a new one!
CAR BATTERIES ARE FOR CARS
Car batteries are designed not to be deeply discharged, or they'll be ruined. Discharge shouldn't be more than 15% & recharged quickly.
A 100Ah deep-cycle lead-acid battery will run the average fridge for about 14 hours. Remember that only 50% discharge is recommended, so 50Ah will be used.
