MPP LVX-6048 Settings youre using

[vothsr]

Thanks for starting this thread. Please try to keep it active. I'm waiting for someone to post parameters using eg4 lifepo

I love the comradery going on to help stormsoul out, but this is not the thread for that conversation. Stormsoul, please start a new thread with these questions on it. If I could copy and paste it all and start a new thread I would do that, but I dont think I have the ability to

I want to keep to the Facts, first list inverter and battery, then what settings are you using, then comment if there is any issue with those settings.
If you dont have the settings for a LVX-6048 or similar inverter, please dont post commentary. System description first, settings second, comments last.

I'll go first:

Hello vcruz28. Since fault 4 is being triggered, voltage must be going below setting #19 (low DC cut off / 40.8volts). Since you also have #20 set to 50.0volts (stop discharging) I just guessing that it never is between 40 .8 and 50 volts... maybe the BMS in the battery is cutting off at 51 volts or something so volts jump to 0 volts causing the fault 4 without the opportunity for setting #20 to return you to grid. What is the SOC / voltage on the battery when you see the fault 4 ?

Change Settings:

#1 - SUB
#10 - SNU
#19 - 48
#20 - 51

Make sure battery charges to voltage above 52 volts.

Then change setting back #1 to SBU and #10 to OSO. I would keep #19 at 48 and #20 at 51, but change if need.
