Out of curiosity, does it work in lead-acid mode?
Nope, it will never start changing the batteriesOut of curiosity, does it work in lead-acid mode?
Even when I unplug the rj45 with communicationEven if you unplug comm?
I won't bother you with photosInteresting. I would think in lead acid mode with a correct AH and charge voltages settings and DOD set appropriately, it should have no reason not to charge since it thinks it is a "dumb" battery.
I bought everything from the same brand. They tested everything (they claim) before shipping it to the USA.I don't have the same brand batteries as you. I have the GSL branded Megarevo with GSL lithiums. I had to update the firmware on my inverter and on the batteries before they would work. After I updated the firmware on the inverter, they would work as lead acid. Later I updated the firmware on each battery and can now use them on Lithium mode, but the charge/discharge limits are not read from the BMS as stated.............you have to set those on the Lead Acid side and then change the battery back to Lithium and restart the inverter.
It looks like 1 is max SOC while the other is low, I think they should be matched up with a charger before connecting to the MRI bought everything from the same brand. They tested everything (they claim) before shipping it to the USA.

I measured each voltage and they are both roughly the same.It looks like 1 is max SOC while the other is low, I think they should be matched up with a charger before connecting to the MR
I have a 48 volt forklift battery charger, but that is a bit overkill.Do you have a battery charger you can use to get them to 10%+ SOC then see if connecting just the batts will turn on the MR?
I took the MR down:Do you have a battery charger you can use to get them to 10%+ SOC then see if connecting just the batts will turn on the MR?
There are never stupid question, just stupid answersDoes the bluesun battery need charge/discharge enabled in bms? Is there a BT app for it or anything?
I apologize if these are stupid questions![]()
Yep, no change :-(Have you tried switching to bat priority mode?
Do you have a copy of the BMS software you could share ? If I am able to read my batteries I might need the update as well !I don't have the same brand batteries as you.

Sent an email to bluesun and they are already on it:I bought everything from the same brand. They tested everything (they claim) before shipping it to the USA.
