Re: PIP-5048MK inverter

atomi Buy a second 5048MK and use it as a grid +/- PV charger only. I'm from Romania (Eastern Europe) and to me this was the logic option (600Eur from Ebay) since I needed more than the rated 4kW PV array MPPT and a locally sourced 4kW MPPT was near 500Eur for that power rating, but the PIP also ha...

Re: PIP-5048MK inverter

ECO mode is exactly the same as bypass mode. Perhaps there was a difference at one point. There is an internal enumeration for ECO mode, for which the removable display firmware would return an 'E' from the QMOD (Query MODe) command. But the King/MK will never return that 'E' because there is no pa...

Re: PIP-5048MK inverter

NuOG I also have 3 phase, one common neutral to the house (L1,L2,L3,N) and Protective Earth (E), but ALL my loads are all 220V, so I have three circuits, each like: Phase(Lx) and Neutral (N) and E. I use the solar system (PIP5048MK) only on the first circuit (L1,N,E). Recently I decided to get some...

Re: PIP-5048MK inverter

coulomb I am sending and checking the proper CRC every time from my Arduino, just when using the console I found out the bug. I'm afraid that a communication error might corrupt a command, eg POP00 to POP02, one bit difference. I do get CRC errors sometimes, when requiring QPIGS, like 1 in 1000 res...

Re: PIP-5048MK inverter

I did some tests with my PIP-5048MK, display fw 2.49 The conclusions are: 1. BAD!!! The display doesn't check for proper CRC in the received commands , not only the Q(uestion) commands but also the set commands, I used something like MUCHGC002 12 , MUCHGC010 12 , PSPB1 12 , etc and always got (ACK<C...

Re: PIP-5048MK inverter

MJS-1 The LFP batteries get as much current as they need, you only set the MAX current available, as the voltage increases they take less current anyway, if we settle for 52.5, even 52.7 there is no need to lower the current (assuming nobody uses a single US2000 on a 5kW install). I prefer embedded...

Re: PIP-5048MK inverter

I thought about a "mangling rs485 proxy" but that's an ugly useless hack. The PIP gets from the BMS only the total charge current: NrOfPylBats x 25A, bulk/float voltages at 53.2V, back to grid 48V, back to batt 51V, batt empty 46V, that's all. Using the USE settings with these settings accomplishes ...

Re: PIP-5048MK inverter

coulomb Yes, you can use getpwr , pwrsys , bat and info commands The battery returns something like this: Power System Information --------------------------------- System is idle Total Num : 8 Present Num : 8 Sleep Num : 0 System Volt : 49381 mV System Curr : -367 mA System RC : 352367 mAH System ...

Re: PIP-5048MK inverter

Pyl firmware is pushing them a bit hard just to fall in spec, just like setting a car's automatic transmission to shift at 4500rpm just to reach the advertised HP every single time. I don't recommend trying to update latest Pyl firmware, no change regarding voltages, much simpler would be to use the...

Re: PIP-5048MK inverter

Hi guys, I have a PIP-5048MK with 4x Pylontech 2.4 kwh batteries and 15x 320w panels (3s4p on S and 3s1p on W, not pushing the inverter at more than the 4kw PV rating). I'm running the RS485 cable comms but I'm not satisfied by the way things go (53.2V charge voltage, down to 10% discharge, fluctuat...
