I really want to read this article, but there are too many spelling and grammar mistakes or lack of punctuation. Please consider spellchecking it?
As you can see if you only drain your battery to 75% (meaning you only use 20% of your capacity) you get tremendously more cycle’s (more than double!) then say using 50%. So when systems are designed for energy storage you generally want your batteries to last a long time (since they’re expensive) so you want the maximum amount of cycles for them, which means that you should only discharge them 80%. As you can see this is getting quite frustrating, as now simply to power you’re off-grid system at night you need to purchase 80% more battery capacity than you actually need.
75 + 20 = 95. Okay, close enough to 100. But discharging to only 20% means you need to buy 500% the capacity, not 180%!
In my shed delivery business, I have a custom designed trailer with a hydraulic lift for the tilt bed and a winch for loading and unloading the buildings. They are 12 volt and I just run them with a car battery.
I'm sure that with such an attidtude, you'll be learning a lot from people with different backgrounds and cultures. /s
