@MJS-1 I saw your post about error #69 on the MK. My friend has 69 also appear. Did you have any good results in trying out the different firmwares? What is #69 exactly saying? the manual shows: "If battery status is not allowed to charge after the communication between the inverter and battery is ...

Hmm, interesting, as there were updates addressing the #08 error. But as I understand you were not notified about that?

Well, I already ordered the Max and it will arrive Wednesday.
We can compare the firmware versions.
We'll see....

Maybe file a complaint /request to MPP Solar / Voltronic. If we all do that, they might release a firmware upgrade....

I have used the MG long term batteryless in both off-grid and on-grid situations.
It works fine.
I did not measure though if there was any grid feedback with the on-grid setup, so I cannot answer that....

I ordered one myself. It will arrive in a few days.
My previous one was also a 5048MG.
I am curious how this new one will be.

I found on this Spanish forum someone who took it apart and reviewed it:
here
I understand it can be quite noisy....

I've had 3 x 9 of 220Wp panels = 5940 Wp connected to my 5048MG from the beginning, both with and without batteries connected, and never had any issues. Your panels might be less than 6A Imp, meaning 3 strings won't exceed 18A. It seems to be the 18A figure that is the main problem. They are 60 cel...

A friend of mine with a single MG has the #8 fault too. She confirmed it happens at night. This setup is batteryless with solar and util connected. My plan was to swap her MG (71.40) for mine (71.71), and see if it also happens with my MG on her setup (it doesn't on my setup). I'll double check her ...

You can press the enter button (right bottom) to start the flashing.

There is a link in this forum:

I flashed 71.71 and everything went fine.
I will post my findings here if anything stands out.

If have sent @derBastler a pm

I replied to this yesterday, but it doesn't seem to have come through. I saw in https://powerforum.co.za/topic/4288-axpert-inverter-switching-to-battery-power-at-midday/ that there is a firmware update for the Axpert MKS II. I've got the MPPSolar 5048MG (@71.40) so I guess can flash this Axpert MKS...

We do not currently have an LFP flavour of this patched firmware. Let us know if you would like us to make one.

Thanks for this weber.
Do you mean with the remark above other LFP's not being Pylontech, like 16s ones?

This is great news! I saw in https://powerforum.co.za/topic/4288-axpert-inverter-switching-to-battery-power-at-midday/ that there is a firmware update for the Axpert MKS II.

Another consideration for you re MS vs MK vs GK is that they all come with the premature-float bugs . We have patched MS and MK (soon to be released) but not the GK, to fix those bugs. In that case my best option will be the MK and then use your to be released patch! Just to be absolutely clear: I ...

You say you wouldn't recommend the GK. In the same way you wouldn't recommend the MG? That's correct. I've got my MG wired with a spd on the panel side and a RCCB type B on the AC side and that seems fine. What do you think? I think many people would be very grateful, if you (or your electrician if...

I would never recommend the GK as it has no insulation monitoring of its lethal PV array. If it wasn't for the fact that you're using Pylontech batteries, there would also be no contest between the (patched) MS and the MK, because the MK (and GK) firmware still seems to have some serious bugs (that...

I am about to create a system for a friend with some pylontech batteries and was looking at the MK and GK forums. Considering what I read here, would you all advise me to get a MS with a patched firmware instead of a MK? Besides that: trying to max out the # panels, would the MK or MS take 6p4s pane...

[ Edit: Even 56.8 V is a bit much for LFP; I use 55.2 V on my own 16S LFP battery. You'll miss out on a tiny bit of capacity, but hopefully will extend the life of the battery by not charging to such a high voltage every day. ] I would say an hour [ edit: for the absorb time ] would be a reasonable...

Thanks coulomb for your detailed answer 8-) Please complain to your reseller, and to Voltronic Power! @Weber and I grow weary of patching version after version of firmware, when the fix is so simple. I absolutely did!!! I sent a complaint to maximum_solar through ebay. The premature float bug arises...

Update of my own OFF-grid project: I have been running my 5048MG now for half a year batteryless, charging our Renault Zoe electric car fine. 'Granny' cable with either 10A or 13A is working great: when the power is not there (clouds or so), the PIP lowers the Voltage, and the car even kept on charg...

exup I was the one with 24 solar panels. Now even 3 x 9 They are 60 cell poly 220W 36,9 VoC / 30,2 Vmpp 7,85 Isc / 7,28 Impp I never had any problems with this setup. I put a 10A DC fuse on each string (+ side). As coulomb said the inverter will take max 18A from the PV. Oversizing is not a problem...

How do you mean, with no power applied? PV power? If there is no PV power, the MG is off, because there is no battery connected. It surprised me too. It seems to be via a normally closed contact, so yes when the power is completely off, I'd expect neutral and earth to be connected internally. The m...

Setting 38 ("Allow neutral and grounding of AC output [to be] connected together") merely changes how the tiny relay on the communications board is controlled. You have to provide an external power supply and relay to do the actual neutral to earth connection. I can't see how that would cause rattl...
