Re: PIP-5048MK inverter

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 s...

Re: MPP SOLAR PIP-7248MAX

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....

Re: PIP-5048MG Batteryless operation

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....

Re: MPP SOLAR PIP-7248MAX

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:

Re: Solar panels in series / parallel

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...

Re: PIP5048MG: 3Phase Configuration: Fault 08 and anomalies.

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 ...

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?

Re: PIP-5048MK inverter

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 ...

Re: PIP-5048MK inverter

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...

Re: PIP-5048MK inverter

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...

Re: PIP-5048GE, PIP-5048GK and PIP-5048MG inverters (with unsafe SCC)

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...

Re: PIP-5048GE, PIP-5048GK and PIP-5048MG inverters (with unsafe SCC)

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...
