Hi everyone, before updating the firmware for my inverter I don't understand which version is suitable for a PIP 5048MS(64V) (PF1) with firmware version 72.40 !!! that from the specifications on the site:

"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.

Hello again, this time with a big problem, one of my pip clone died today (has not the corona virus). It only clacks on start and it gives no error. Check out the youtube video. I have already taked apart. Without scc board has the same simptome but without the clicking sound. Please help

Ok thanks, as soon as possible I update the firmware and I will inform you on the forum of any notable differences between the two firmware (72.40 / 72.20e).
Cordial greetings

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

Even the replacement Arctic fan is not showing 01 error.

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
