i would like to thank everyone who spent time answering my stupid questions and helping me out to fix my solar problems. i changed my solar panel setup from 12v to 24v, got a new battery and now i harvest about 850 wh per day.that's a huge improvement that allowed me to power a fridge among other things (a word of advice for off-gridders, buy a dual function chest fridge, huuge difference form ordinary ones) .
a question about batteries: since a battery is considered to be charged when >12.8 or so, what if the battery is charged at 13v or more? how charged is considered? my battery is at 12,64v every morning, what state of charge is that considered to be? (gel vrla battery)
