i have a 6KVA Must inverter and 51.2V LIfepo Must battery the issue i am facing is that the inverter is not charging the battery when both solar and grid power is available, it appears to prefer Solar to Grid to charge the battery. but i`ve alo noticed that when we have grid power at night, it charges the battery. are there any settings i can make to prioritise grip power because i want the battery to be fully charged whenever load shedding hits. settings 01-UTI 02-APL 05-BLU 10-SNU
