It couldnt hurt!
The reason I ask, is because im guessing at some point your setting 02 was higher, and then you tried EG4 mode it reset itself to 20a because it thought you only had 1 battery in the bank.
I had this issue when i first started and had my dip switches set wrong
Signature solar tech had me set to 20A from 60A on setting #2. BMS comms do not work for me yet. It gets error 61 code even after updating.SS tech mailed out replacement cable. He thinks it may be a simple hardware defect for the cable. I have tried reversing both sides of the cable but did not resolve error 61 code. I assumed #2 setting was only for utilities not overall amp setting. Adam de lay corrected me on that misunderstanding. Option #11 is for utility amp limits.
