    MPP-Solar LVX-6048

    So I tried again paralleling the inverters after removing the ground neutral bond on both inverter. I keep getting the random split second reset in one of the inverters. Both are using the latest firmware 63.06. removing the bonding screw did helped on the humming noise and eliminated the...

    any news on a paralleling fix? or fault 8 solutions?

    MPP-Solar LVX-6048

    I tried both ways it did not seem to make any difference. At this point and given that the vendors have not come up with new firmware or a fix, I am in the camp of getting rid of this inverter, both the Mpp and EG. Looks like running in parallel will not happen.

    MPP-Solar LVX-6048

    I did had crazy vibration and noise when in parallel and hooked to solar and grid. It was crazy I was worried enough that I was tripping the AC breaker when I was not in the house. I also saw continues errors and faults. In the end I switch back to operate as single unit. Not what I wanted...

    LVX-6048 3 Second Power Outages

    Sorry, but at this point it is a well known issue with the LVX6048. The units does not work in parallel. I know it sucks and it is probably the main reason to get, but it has all kinds of issues when it is connected in parallel... change it to single units and almost all the issues will disappear.

    At this point is hard for me to recommend this with the issues we are experiencing.

    MPP-Solar LVX-6048

    Update..... Looks like everything runs fine until the batteries reach about 80% of charge at that point the flickering and the weird humming noises start. So I am going to try using them individually (not in parallel). it is very clear the inverter does not like having all three sources energy...

    MPP-Solar LVX-6048

    Today I rewire my ground to a ground bar. The house turn into a disco…. Everything was flickering. I pulled out the ground and it went away…. I am sure that if I dont run them in parallel everything will be fine.? not sure what my next step is…. Split the circuits or sell them and go for the...

    No faults since last tuesday.. I changed the inverter settings to OSO…. Only solar charging seem to made the trick

    The fault is described as Inverter negative power.

    MPP-Solar LVX-6048

    Fault 60 again… it happens as solar is ramping up and is connected to the grid…?. Same inverter but in reality it is the only one connected to all three sources. Ill do a check with the other inverter during the weekend.

    MPP-Solar LVX-6048

    Wierd thing is only one of the units faults… the only differene is secondary firmware version. One the no fault inverter it is 6021 and on the faulting inverter it is 8022.

    So today I got fault 60 again. Grid went out mid last night and power came on the morning as PV power was ramping up it faulted…

    MPP-Solar LVX-6048

    Just to clarify both my inverters are connected to the grid. At 51v the sistem will switch from batteries to grid. That should only happens on the days I have week solar production. Roght now only one of the inverters is connect to PV. That will change in the next couple of weeks when I add...

    ???? You referring to the grid?

    MPP-Solar LVX-6048

    So I am calling it good for the fixes on the faults….. 3rd day no faults. The only weird thing is the change from SUB to SBU on its owns… it only happens like that SUB to SBU. Not sure why. Dont pay to much attention to the battery %. My pack is not communicating with the inverters so that %...

    MPP-Solar LVX-6048

    Here is mi idea on the changing parameters on its own. I am monitoring the system using Solar assistant on a Raspberry pi 4. I think that having multiple windows open, some of those could be showing sbu vs sub based on when I checked the system previously. I will remove the Pi 4 and will...

    MPP-Solar LVX-6048

    Ok so here is what I have done… ensured there was a single neutral-ground bond across the system my grounds are all bonded to a ground bar outside the house upgraded the firmware to the latest (06?) firmware updated to 6306 maintained a grid tie, but use the tie only to charge your batteries...

    It just change the setting from SUB to SBU on its own!!! ?

    MPP-Solar LVX-6048

    Day 2. Solar production 10.6k. No faults, still using both inverters in parallel with one of them connected to all three power sources. Looking good

    MPP-Solar LVX-6048

    End of day report… No faults today, no light flickering. Pv production 9.76k. No hearing the weird humming… no power rest reported by the wife (not a reliable source) Will keep reporting

    MPP-Solar LVX-6048

    jsheffer, I have not. I have dedicated wire connected to a ground bar.... your idea would be to use no ground on the inverter? All, As of now no fault during today's solar production.

    MPP-Solar LVX-6048

    Today we will know. I am not at home but will monitor remotely thru Solar Assistant. I was running it like image 1 ( according to the paralleling kit) until I saw the lvx-6048 manual. During that period I had no issues other than the random reset or loss of power with all three sources...

    Yeap both update to 6306. Just changed current balance cables to follow image 1 aka Ians connection on youtube. Stay tuned!

    MPP-Solar LVX-6048

    Here are 2 images of the paralleling diagrams 1st image shows instructions on the paralelling kit image 2 is LVX-6048. The vidoe in you tube from Ians solar project went with the first image. There is a clear difference on how the current wires are connected.

    MPP-Solar LVX-6048

    Bad luck… went to check and found one inverter in a fault. Same one that was faulting before…. There is something with grid, batteries and solar that it doesn't likes. The other inverter does no have solar and no faults.

    MPP-Solar LVX-6048

    So inverter 1 keep showing this error…. Inverter 2 is 1/3 updated…. I will switch displays once Inverter 2 is done just in case the connection failure has something to do with it. Ok so switching displays did the trick… will report back how the two in parallel are doing once I complete the...

    Yes grid, batteries and solar connection. when all 3 are present and is in sbu the fault s almost inmidiate ok I am getting a connection fail on the update any ideas?

    MPP-Solar LVX-6048

    I change to SUB from SBU and it solve the fault....... but its like the inverter does not like to see grid voltage when charging from solar. BTW I only have 2.2k of solar nothing big for now. (1 string of 6 @ 380w). I am going to update the firmware first and check if that helps. if not I...

    Also the battery icon started blinking totally empty…. Any idea why? Totally regretting selling my Schneider 4048….? update: the new firmware took care of this odd situation!

    MPP-Solar LVX-6048

    Update….. I had the units in parallel and was only experiencing the sudden loss in power every other day…. Decide to keep just one hooked up while we fogure out the parallel thing. Now that one is consistently throwing fault 8 high bus bar voltage…. Never had that one before

    MPP-Solar LVX-6048

    All, there is a difference in the wiring of the current balance wires between the manual for the lvx6048 and the manual from the paralleling kit. Doy you think that could be part of the issue?
