Did not get this error anymore since I stopped changing the parameters. I think these inverters could have an issue to communicate changes in the setup in between each other.

I think I am blessed as I have been running 3 LVX6048s in parallel for almost 2 years without any major problems.

@Mickey PR Obviously I was late. File not found. Could you please upload this once more?

LVX6048 are not UL listed. Primarily I'm feeding back to the grid with my SMA Sunnyboy which is in parallel to 3 LVX6048, but if I generate excess energy, I also let the LVX6048 feed into the grid. I don't live in the US by the way.

Nothing else has changed compared to older firmwares, just feeding to the grid is working with v63.02

No, no issues with battery charging.

Just one more, that the inverters sometimes go to fault with Error 60, when the grid goes off and they were feeding power to the grid.

Feel free to read all my former posts in this thread. The following posts are about issues. https://diysolarforum.com/threads/mpp-solar-lvx-6048.19099/post-278438 https://diysolarforum.com/threads/mpp-solar-lvx-6048.19099/post-282202...

The settings for my 35kWh DIY LiFePO4 are 56 bulk and 55.8 float. I've never seen the voltage hit the 56V. I get 55.7V when I check the voltage in float.

I had the same problem, when I got my 3 units in May 2021. I reported this issue to MPPsolar and they sent me 2 firmware updates. The 2nd firmware, which is 63.02, fixed the problem, but there are many errors left which they never solved. When I insisted to get a fix for all the remaining bugs...

The fan speed of my LVX6048s is regulated gradually, depending on the load or temperature. I think that the higher heating of the LVX6048 compared to the LV5048 is due to the built-in copper / iron transformers.

Magic. History is working now.

Rebooting the inverter / wifi didn’t work for me. But 4 days ago I found the devices logging and available for control just like that.

Really strange. The opposite happened to me. The first time that logging and controlling is working on Solarpower and Watchpower App. Fourth day already. Except viewing history.

Same here. Today is the fourth day that for the first time both the Solarpower App and the Watchpower App are working continuously with my LVX6048s, without having to delete and add the devices to my account again. Except viewing history. Just before, I had installed a system update on my...

Yes, the LVX6048s have WiFi, I downloaded the correct app version, I added the 3 devices to my account and they showed up online. At this moment they started transfering data to the app. But 1 or 2 hours later the data transfer is stuck. The app is showing then the latest values all the time as...

Ok, so you have no experience with the data transfer of the LVX6048s. In my case, neither the SolarPower PC software nor the app works with the LVX6048s. I tried the WatchPower app yesterday, but with the same issue, the data stops updating after a short time. I have installed 4 LV2424s in...

How many LVX6048 have you connected in parallel?

Thanks. Looks nice. I am only afraid that my LVX6048 could have a general communication issue, as they always go into fault mode with Error 80. Even some of the unique common parameters (such as 01) they do not communicate with each other. I reported all this to the MPPSolar support, but they...

Is Solar Assistant free software to download? The SolarPower software offered by MPPSolar does not work with my 3 LVX6048 in parallel. Values are displayed incorrectly or not at all and after 1-2 hours the devices are no longer detected by the software. Similar in the app, which does not offer...

Thanks for sharing, but not working for me.

Hi, the SolarPower APP does not work for me. The only difference since May is that now the three LVX6048s in parallel show up online, which they didn't on the first try, but the data on the APP is pure fantasy. According to the APP, I generate a huge amount of PV energy every night, and the...

A quick update to the issues I'm struggling with running three LVX6048 in parallel. The devices switch and change randomly paramerer 01 themselves: (every 20-30 minutes) SUB ... SBU ... SUB ... In UPS mode, my LVX6048 do not accept the stable input power from my provider (240V/60Hz) and they...

Obviously the app has updated, because my three LVX6048 are going online now, what they didn't before, but all the data on the app is nonsense. The app shows hybid mode, when the inverters are in battery mode. Each inverter shows far different AC and DC voltages although they are connected in...

I found, that some settings must be applied one by one to make them work. Did you change multiple parameters in setup mode? Try to enter in setup mode and change only parameter 24 bOn to bOf, then apply and ESC. On mine this works.

I would recommend to report this issue to your seller or to the support team of MPP Solar (depends where you ordered from). Probably they are the most indicated to help and to find a solution as you purchased a brand new device. In my case the support team in Taiwan has sent me already 2...

Wow, mine also got dropped. And one of mine (I bought 3) came with a disconnected cable inside. I could not turn it on with battery only and I got no AC output, when it powered on by AC input. Later I found the loose cable, but I don't think that it could come loose when they dropped it.

Yes, this is the computer software you can download from the MPP Solar website. The solarpower app for smart phones doesn't work yet with the LVX6048. They told me to have an working update at the end of June.

Solarpower software.

mine also do

Thanks daviddakers, yes I did, I'm quite famliar with the menu and its settings as they are almost the same as the LV2424 settings which I'm running 8 of them for several years now.

So far I had 4 LV2424 running, which I also used to feed energy into the grid. In order to increase the maximum connection power, I decided on 3 LVX6048, because I also saw an advantage for me in the higher PV voltage for larger arrays and I liked the 48V battery voltage. As the ability to feed...

Bought from MPP Solar, Taiwan, sent by DHL to the Dominican Republic.

They dropped yours too. I purchased 3 and they all came with dents, broken screws and bent handles.

2 houses (=4 condos) with 4 AC, 4 water pumps, 5 refrigerators etc. living in an abandoned region in the Dominican Republic. Lots of black outs over the year and danger of long blackouts in hurricane season. I replaced my 4 LV2424 with them 2 weeks ago. No over temp faults so far.
