This concept just makes the charging algorith much simpler. The battery charges till maximum charge lvl 14.7V is reached and cutoff so long till minimum lvl is reached 13,8V. If the sun goes down the charger sleeps. Consumcion is 5mA asleep thx too a cheap and efficient 2A stepdowner for the Arduino…
