[ 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...

I would really like to be able to run the 400 volts DC from my solar panels directly to the 350-400 volt DC battery in in my Leaf through the CHADEMO DC charge socket. That would be very cool if that became possible. No idea how Chademo works and if you could build a smart EVSE using the DC from th...

Also, we don't have any 450 V MPPT firmware to patch, apart from the VM (Value Mppt) models. So far, I haven't found how the main processor talks to the Solar Charge Controller at all. So for some time, quite possibly forever, there won't be patches for the MG. I get it. :D Can I somehow extract th...

www.youtube.com/watch?v=n9KCl8SAh5Y I have wanted one of those for about 10 years ( but they do not exist I have been told). I ended up with a hybrid system instead. There was nothing worse than running a generator on a very sunny day, with solar panels on the roof, but a mains blackout. Yes, that ...

Hi all, I just wanted to share here that my dream came true yesterday. Thanks to this and other forums, I made this work!! (I know It is a bit off topic, as this topic is Non-EV, but it is also about the PIP (and I also have LiFePO4 batteries :D) We are now charging our Renault Zoe electric car off ...

Hi all, I just wanted to share here that my dream came true yesterday. We are now charging the Zoe off grid! I found an inverter (MPP Solar PIP-5048MG) which does not need the grid or batteries, so I have a direct PV ->EV system. I am using the granny atm in 10A mode. Today I'll try 14A. Future will...
