"72.40-72.89: You are running older hardware, rated at 4kW (PF0.8). You can update to the latest patched firmware 72.70ℓ or 73.00ℓ."

My inverter would belong to these specifications while the real features are different.
Thanks for the help
So the day has finally come, as we thought it would, that the two different 72.xx series overlap. Thanks for letting us know. @Coulomb will need to edit the "What firmware?" post, to take account of this new situation. The patched firmware suitable for your inverter is 72.20e. But you will miss out on whatever improvements are in your version, compared to 72.20. We hope that someone will eventually send us a firmware update file for this new pf1 72.40 so we can see what the differences are between it and 72.20, and consider whether we will port our patches to it.

Hi guys,

What temperature is measured and than displayed on my Pips 4048MS with your latest "e" FW?

It shows about 31 and upper heatsink is for sure about 50 degrees Celsius.

Other question is: Is it possible to get all display menu items on both left and right side od display? That would be most usable.

Thank You and best regards

It's the highest of 3 or 4 temperatures:
  • The battery-side MOSFET heatsink
  • The inverter proper (IGBT) heatsink
  • The transformer temperature (there is a bead sensor near the transformer)
  • The SCC heatsink temperature, if the Solar Charge Controller is on and communicating
It shows about 31 and upper heatsink is for sure about 50 degrees Celsius.
By "upper" heatsink, do you have the older style with the black heatsink fins on top? I assume it has a sensor on it as well.
Other question is: Is it possible to get all display menu items on both left and right side od display? That would be most usable.
You can get several items displayed on either the left or the right side. But items that are definitely inputs are available only on the left, and things that are definitely outputs are only on the right.

Two bulget caps on the main board. I presume are the filter caps on the power source for the cpu board. The experience members can confirm or deny this statement. Attached is a pic of this caps.

I'd say so; that happens to be a part of the main power supply (the very back end, connected to the secondary windings of TX9) that I haven't traced yet. I'd say that some of those capacitors also smooth the ±15 V and ±12 V supplies which drive part of the main board other than supplying the control board.

Well done on the repair, and thanks for the repair report.

Hi,

Yes I have older style inverters with the black heatsink fins on top... and on display temperature is 31 and heatsink is, measured from outside about 50 degrees...

So my observation is that temperature is not displayed properly (max temperature on inverter).

Is this problem solveable?

Thank You for informations and best regards

I assume that this is happening during the day while the Solar Charge Controller is running. It could be that the SCC sensor is on the MOSFET heatsink, and not on the heatsink on top, which I believe is for the inductors only. Maybe you have inductors with a shorted turn, causing more heat there than in the MOSFETs.

There is a tiny chance it's the SCC firmware; what version SCC firmware (U2) are you running? This version number is not visible at night.

SCC is original 1.24 version.

I have no other problems with inverters... they work perfectly. :D

Hi ,
Today i test my DLC, created with arduino and 2x LTC6803
work ok, but now need 2 serials data to may inverter, to connect DLC and modem data (sent data to server)
how to solve this?

Hope your all good, Some sad news my good mate Rob Black VK2BBR passed away late last year, he used a pair of 5048's. Well its been a while here is my update, I installed a pair of PIP4048HS inverters with a 20KWh 15S LIFePO4 Battery and 6Kw of solar 3Kw on each inverter 4 1/2 years ago. This has worked really well till last week when one inverter died, I did buy two new PIP5048MS about 18 months ago to change out the 4048's but i didnt get around to it, So now i have two new PIP5048MS inverters with upgraded software THANKS WEBER and COULOMB working well. My second hand Thundersky batteries are now 10 years old and still working nice they are about -15% down on rated capacity. The solar charge controller part is still working in my 4048HS so i will put some more solar on the roof to boost the winter input. but all in all a great outcome. and one very happy camper.

Good morning,

hope that all of you and your family are good !
As i have to spend more time at home i did some tests on my 4048 with 73d firmware ....

So I was very surprised :
I tried to put my setting 12 (back to grid) at 47v instead of 48v and my inverter switched back to grid at 48v during the night.
So the night after i put 46v in setting 12 and the inverter switched back to grid at 48v !!!!
I'm in SBU setting 1 and priority charge to solar mode.
I check the lowest voltage reached with my BMV702 monitor. (each night 48.0v instead of 47 or 46)

So i decided to read all my historical datas and this happened roughly after the 73.00d update (this is the only update i did for this inverter)
But there is maybe no link with it.

1) Did some of you guys noticed such a thing ?
2) Is there any way that the update "bricked" this setting to the value before the update ?
3) Did the update got something in it to avoid to take in account the setting 12 below 48v.

Regards.

Rick

I guess you mean patched firmware version 73.00d.
3) Did the update got something in it to avoid to take in account the setting 12 below 48v.
My guess is that you have the low DC cutoff (setting 29) set to 47.5 V (if using the LFP flavour of 73.00d) or 46.0 V (if using the non-LFP flavour). See FAQ 2. Don't feel bad; this is undocumented behaviour, and many users get caught out with this.

The factory firmware behaves the same in this respect as our non-LFP patched firmware. You may have changed the low DC cutoff setting at around the same time that you updated to 73.00d.

Hello, and thank you very much !!!!
I read this fast this morning and only saw the lfp setting !
All was written in this page !
Yes : i got the 73.00d
Yes : Before I put 46 volts (for the 29) so now i've corrected to 45v (in the 29) and 47 volts (in the 12) i will have 2 volts and 51volts (in the 13)to reach the 4 volts differences.

I ll check it tonight but i m pretty sure of the result :-)

Thank you very much

Hi All,

Thanks to all the peoples who "hacked" the firmeware and added very useful functions to it, I appreciate the work you did.
I have some questions and maybe somebody can help me, as normal :-)

I have a Steca PLI 5000-48 with Pylontech US2000B, I read from both devices via Serial communication and created a Flot via IOBroker.
The spec. for the Pylontech mention as max. Volt is 54,00 but in the QPIGS command I can see when the SoC is 100% reported by the inverted
Steca: 54.20 V
Pylontech: 52.80 V
Should I lower the value on the Inverter by 0.2 V or 1.4V independed which setting is currently used ?

The SoC vom Steca shows quite strange Values, is this normal and should I just ignore them (Steca SoC=green and Pylontech SoC=Red) ?

I have attached a picture with the detals.

Hello everybody.
I have a question:Why a 30 mA RCCBO connected at the AC output of Effekta is not working in battery mode, as a residual current protection?
The grounding (PE) oh the site is properly done.
Either if I connect with a wire the L or N inverter output to the grounding, the RCCBO does not disconnect.
The same situation appears even with Menu 38 set in DIS or ENA.
In by-pass mode is working.

54.0 V is an average of 3.6 VPC (for 15S like Pylontech 48V); 3.6 V is the highest voltage an LFP cell should ever see. So you should not be charging to anywhere near 54 V.
Should I lower the value on the Inverter by 0.2 V or 1.4V independed which setting is currently used ?
The recommended maximum charge voltage for Pylontechs is 53.2 V, and I believe that's very high (I suggest 51.8 V).

Yes, the SOC reported by Voltronic Power inverters is for entertainment purposes only (if you are using an LFP battery; even if you are using lead acid, it's a very rough guide to state of charge).

Well I have had the two PIP 5048MS inverters installed a couple of weeks now, and have noticed two interesting things. First the mppt solar charge controllers do not input nearly as much power to the battery as the old PIP 4048HS units. My solar panels are running about 70 volt dc in. And second to that and more importantly to me the PIP 5048MS are taking out my ham radio, they are very dirty RF wise. And generate lotsa QRM. So I will go back to the PIP4048HS charge controllers and see if what I think is happening is? Anybody else experience this? The noise is particularly bad on 6 meters my favorite band. Tom

Well after hooking up a PIP 4048HS to do a comparison on the solar charge controllers on the 5048MS all is not what it seems. And wise words from my dad “ Never believe anything that you hear and only half of what you see” ring true again. The outputs differ greatly with about 500 watts of sun the HS wins about 9Amps @50v out the MS 4.5 Amps @50v.
With about a KW solar the MS wins on the clamp meter showing 20.5 Amps where the HS shows 19.5 Amps I will wait for a full sun day to do more testing but don’t believe the watt display on your PIP my MS show about 200 watts less on the display than the HS inverters but my Fluke clamp meter says that’s BS.
I also tested RF Noise and HS has none. But the MS are really good noise generators :(

Correct me if i'm wrong The 50w was the inverter self consumption.
well I have a 5048HS running the house and 2 other separate chargers, there is 1650w of panels (6 X 275w) connected to the internal pwm, power is good but is hindered by the 20m of cable it runs through.
when in use the fan speed increases greatly when its using the power from the pwm, which keeps the inverter very cool, the response to power demand is not fast.
The 4048HS in the shed, the fans don't do enough to keep it cool, so I had a pare of 250w panels spare and connected them to the internal pwn, thought that would help speed the fans up when in use, but had no effect, also it was very slow to respond to demand once it got going it was doing 450w up to 600w if I was to believe the readout on the inverter, at the time the inverter output was 1700w.

When we got the 5048MS to try, we took the 3kw of panels ( 90-100vdc input) off the PCM60X and put that into the MS unit, it seemed to make more efficient use of the panels and respond fast to demand.
never had the time to try anything else.

Great stuff djonexx! Thanks for letting us know. I look forward to hearing how you go with Dynamic (Charge) Current Control. Dynamic Load Control may also be of interest, to get that no-load battery consumption down, when we get around to implementing it for the PIP-4048MS.
I know it's been a while. I since implemented Dynamic Current Control but it doesn't seem to work in my 3-phase configuration. I see no blinking dot in the display or any sign the inverters behave differently.

However, the commands above seem not to have an effect on the inverters and even so the LG RESU signals (rather abruptly) that the maximum charge current should be set to zero when the battery reaches 100%, it still trips the contactor and disconnects the battery. So for now I'm using the rather safe approach of setting the Bulk and Float voltage values to around 57.5V and not charge the battery fully.

Has anyone tested this in a 3-phase configuration? Is there anything else I should try? the inverters are PIP-4048MS, running firmware 73c.

How do you know the identifiers are 2, 3 and 4. I'd expect them to be 0, 1 and 2. Do you receive an ACK in response to those MNCHGC commands?
