I wonder whether I could use my Morningstar PS-30M Gen 2 to charge a LFP battery, using its gel-battery charging profile. The voltages in the profile differ slightly from the ones that the battery manufacturer recommends. Here are the numbers, first number is for the charging algorithm of the charge controller, the second one is the charging recommendation from the battery manufacturer:
absorption: 28.0V / 28.8-29.2V
float: 27.4V / 27.6V
low voltage disconnect: 22.8V / 21.6V
low voltage reconnect: 25.2V / 24.8V
high voltage disconnect: 30.4V / 30.0V
I am mostly concerned about the absorption number (will 28.0V be enough to sufficiently charge the battery?) and the high voltage disconnect (will battery damage occur if the solar input is cut off only at 30.4V instead of 30.0V?). Full disclosure: the battery in question is an Ampere Time 24V 100Ah.
