Increased the float and get better overall charge state on a day to day basis.

Great thread (and idea)!
Solved my lack of confidence in the specs I have. (... and the faulty default battery management I need to investigate ...)
Here's mine.

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 don't have the settings for a LVX-6048 or similar inverter, please don't post commentary. System description first, settings second, comments last.

Here are my tested parameter results:

Inverter : MPP LVX-6048
Battery : 2 x Jakiper JK48V100PRO 51.2V 100Ah Server Rack LiFePO4 Battery for a total of 200 Ah
Solar panels : 12 x 480 watts Bi-Facial = 5760 watts of solar panels
Inverter mains : hydro input

11-60a, 80a, Maximum charging current augmented so that maximum solar energy could be accumulated more quickly when cloud moves away.
13-30a, 10a, Maximum Utility charging current was reduced to minimal value of 10 Amps so if there was not enough sun it would charge from utility more slowly than solar and try to keep efficiency higher.
14-AGn, USE, User type chosen for battery because the Pyl or Pylontech type does not seem to communicate correctly yet. (... problem to be solved ...)
17-56.4v, 57.6v, Jakiper battery value in the specification section for BULK charging
18-54.0v, 54.1v, Jakiper battery specification is 54.08v as float voltage but 54.9v is perfect for me "0 amps on battery display" when SOC is 99.5%
19-40.8, 41v, Jakiper battery safer value so battery BMS does not cut off too early or before the inverter does
20-46v, 51v, Stop discharging battery when this voltage is attained. The SOC is at 20% here so fine for me "I don't want to drain to 0%. 15-20% SOC is fine."
21-54.0v, 54.0v, Left at default value because observed the Jakiper battery SOC @ 98.9% when charged and not working or "floating". Fine for me.

Tell me yours and comments on mine vs yours:
Many tests made. These are my results.
2022-07-11:Increased the float value and get better overall charge state on a day to day basis.
2022-07-14:Changed priority from Solar-Utility-battery to Solar-battery-Utility (param #01) to cycle completely both batteries together
2022-07-15:After full discharge-charge cycle with 2 batteries, I reverted to 54.1V for float voltage (param #18) and gave 99.8% SOC

I have a pair of these i just installed and could use some help configuring. I tried to change 01 to sbu and got error 8. I have not set slave and madter or 180 degrees off. Understanding the button pushes and when to be in standby would help. grid assisted and a pair of seplos 280ah units tied in just fyi.

If I can help I will. Did you check the book on error 8? Do you want to do 240Vac split phase in parallel?
Maybe this could help?

See attached manual for the MPP Solar LVX-6048 :
Says Fault 8 is Bus voltage too high. That likely means that the battery output voltage to your devices DC bus is out of specifications... need to check your setup...

I have the manual and found what fault 8 was. After reading it seemed i need to set batt voltage and something else. Option 12 and 14 before i change option 1. But those warnings are not anywhere Before hand. So that is why i was looking for smarter specific steps. Do i kill everything but battery before i do any changes. Those kind of q and a things. I dont want to explode the garage lol. I can work with someone in detail if needed. It should not take long i believe. Just tell me what i need to do. I have watched videos. Wills. And watts247. Etc.

I do know that if you provide more than the recommended PV voltage on the pv inputs the LV6048 will generate copious amounts of white smoke.... if you disconnect the offending pv inputs within 5 seconds, your inverter will likely survive like mine did and just heat the circuit board traces to their smoke point without too much damage!

it pays to look closely at max specs before throwing the ON switch....

Jeff (humbled many times by all this new technology)

I made sure voltage was good. I just need to do initial config ie master slave and paral so i can run a 240 v item. Set batts to lipo4. And priority to sbu correctly. Then i should be good. I just need better than manual guide. Its a little confusing. I will give it a shot tomorrow. Tips would be good.

How much voltage did you connect?

6s2p x2 into a 4 into 2 combiner box. each inv gets one leg. These are 400 watt pnls. Ican get specifics if needed for amps of pnl. It was within limits in that cofig for both watts and amps with headroom for winter. Typing on ipad while in garage. So not being verbose right now. Oh 24 panels btw.

Ok i think i got it. Followed Ians video. Watched it a few times. Got confused with old 6548 video and setting the 180 degree on slave inverter. On the lvx. The wiring between them does that. In fact paperwork didnt match video. The black and red wires showed out to in on the manual and the video showed left to left and right to right. Set the batt to user and left default settings for now. Set priority to sbu and put them into parallel with hs and sl settings verified that they stuck.

Everything is on now with batt carrying The load. I see the grid icon but no line to inverter i think it will kick off when batt drains. Blinking green Was a good sign. will monitor tomorrow to make sure it acts the way i think it should. Might bump batt down to 10%. Instead 20%. the seplose cable kit was warm to the touch. Compared to after buss bar. I know the guage for them should b e 0/2 and 0/4 on that left side from buss to inverter. I thought their kit would be good enough But i think it should be thicker. Just my thought.

I need to send a pic or two. Once i clean up the the wires. I also want to install breaker after T fuse. Thats all i think i need. You pros will have to tell me where i am messing up something.

Now i have error 52. Bus too low. Batteries finally cut off bu grid assist did no pick up. It is early morning and sun is barely out but enough to show pv1 on the display but nothing is powered atm……ok i powered off main and disconnected batt. Powered up main breaker/grid and batt and solar all came back on and its working. Prob not enough sun yet to charge battery cause its not. I will ck later when sun is up higher. Batt then load is preference i set. Question. Was this a case of after last setting bringing everything down then up again cause ladt night i did see the circle for grid but no line to the inverter. Now it is and assisting the load.

last edit. Going to sleep a little. Ok i had power batt off both of them and power master back on. Both came up one at a time and started charging. Looks like solar is charging and inverter fans spun up with good amp input to batt. I must have some setting off. At this point things should fail over and back without what i did today. Back after a nap.

Did your battery's BMS hit low voltage disconnect?

Yes it did. Then util never picked up and once i got it all running again i. Had to power off and back on the batteries to get the inverter to charge them. Right now i think i need to adjust option 20. From default for these diy cells. Both inverters have blinking lights for solar and batt charge. Batts are at about 50% at 12:30. One is pulling a couple amps like 4 to assist load and the other is charging batts and its fan is loud.
there is a symbol for grid atm but no line to either inverter. I did a few min ago have a power bump. Lasted like 5 seconds and all is fine. Was strange.

Set the back to grid voltage in the inverter settings to higher than the voltage than the BMS will disconnect at

This is option 20 correct. Default is 40.8. Batts last night were below 5 percent. Actually prob lower. It was a bit latter when it dc’d.
checked seplos 280. Mason bms. It cuts off at 41.6. I will do as you said and bump it past that. Probably 50 or 51. I need to ck what is best for lifepo4 cells again.

Ok I set option 19 (low DC cut off battery voltage setting) to 46.0V. I also set option 20 (Battery stop discharging voltage when grid is available) to 50.0V. after a few min while I was checking battery SOC which had climbed up to over 50% had now dropped to 15% SOC on master battery and 21% SOC on the slave battery, kicked over to grid assist with no issues. now the voltage was above 50.0V on the battery screen so I wonder if its reading from the inverter is a little off. I think its still ok to kick over where its at. I live in Tucson and some monsoon clouds are rolling in cutting panel output a little. anyway I will gather all settings in the next day or so and post as original poster is requesting. thanks again for all the help.

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.

Are you still running these settings? I also have trophy, I feel like a float that high would make my bms go into over voltage.

I am still running those settings, and it seems to work well, havent had any overvolt conditions

I have been hesitant about sharing my settings because I keep tweaking and testing results. I wouldn't want anyone to believe these are tried and true.

I have 2 100aH Trophy batteries.. my lvx6048 settings of interest (for the last week or so anyway):
01 - SBU
05 - BLU
10 - Solar & Utility
11 - 120
13 - 100
14 - User
17 - 56
18 - 54.4
19 - 48
20 - 51
21 - Full

I usually get overvolt warnings from the BMSs when the batteries reach 80%+ SOC. Usually after they reach 80% they will float for an hour then magically jump to 90%. Only 2 times have I made it to 98%. Usually my inverter SOC will think 100% SOC and quit charging around 80%, I guess based on voltage. I do not have the lvx6048 data linked to the batteries (but the batteries are linked to each other). They generally stay within 5% SOC of each other.

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

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.
