Help.. My system got up to 14.4 in the sun and then settled around 13.3. I then plugged in a 1200 watt load. Within minutes it showed 12.7 volts. Turned off load. So I turned on shore power and it took the charger about 20 mins to charge to 14.4-14.6. It showed bulk, then absorp then into float and shut down. Tried load again and did the same thing. I have it set to lithium. Can't get my shunt to work yet. Should I continue running the load till the bms shuts down the battery. It seems to me that the batteries are not accepting a charge from solar or shore power. Thanks for any help...
