Hello from Bulgaria
:)
I think to buy 2 parrallell PIP5048MK to change my old inverters.

Did PIP5048MK will support grid assist when work in parrallell?


Thanks

Two PIP-5048MKs in parallel will operate much like a single PIP-5048MK, but with a higher power limit.

I assume you will connect both units to the grid via their AC-in terminals.

Whether these models will "blend" power from the grid with PV power isn't clear to me. In Line mode, the manual says "The unit will provide output power from the mains . It will
also charge the battery at line mode." It doesn't mentione PV power going to the load. However, one of the diagrams shows PV power going to the battery and also to the load.

Can other PIP-5048MK / Axpert King users confirm that blending of grid and PV power takes place under the appropriate settings?

From MPP Solar confirm me that inverter will use PV and grid power in same time to power loads

Can somewhone which really use PIP 5048 MK .also confirm me this ?

When the PIP-5048MK is running in 'Line' mode, the battery an 'energy pool' so to speak, the DC>AC inverter is always running to supply AC to the load.
Grid and Solar power flow into the battery (or not if it's fully charged) - power flows from the battery to supply the load.

If the Solar input is insufficient, the Grid supplies more power to the battery/load.
You can set limits to the 'mix' of Solar/Grid input power.

I run mine in 'ECO' mode during the day (Bypass relay operating) this reduces the losses caused by the DC>AC conversion and either source of input power goes to charge the battery.
At night I run in Battery' mode to use the stored power at night.

Seems to work for me ;)

This workaround with SolPipLog looks really interesting.

I must have missed an email notification for this topic in early November, so didn't get any updates - until I logged back in this week - ho hum...

Many thanks to coulomb, weber and others who have done the work on Beta Version of Patched Firmware 71.80d for PIP-5048MK/Axpert King 5K viewtopic.php?f=64&t=5955&start=125#p76178

What follows is a belated update on my previous pst viewtopic.php?f=64&t=5955&start=75#p74386 it's a bit long-winded I'm afraid...

Despite getting no practical support from MppSolar for my 'obsolete' PIP-5048MK, I decided not to give up.
So I kept emailing them with my issues, requesting a firmware update so I could use a PylonTech battery and it's BMS - even though I hadn't yet purchased one ;)

Eventually, near the end of July I got a reply:
'Regarding to the BMS, we will consult with our engineer whether this unit can be upgraded the BMS function through this way'
A few more weeks passed and many more email prompts produced:
'Regarding to the BMS problem, the unit needs to be replaced a new control board for Pylontech battery. We need special order this card. The lead time is 4-5 weeks approximately. Are you willing to wait? The control board is 25usd/pc'
Progress! - I was skeptical, but on 8th August I placed the order, paid by PayPal - which came to $60, with $30 shipping and $5 for a BMS cable.

So I waited the 5 weeks but didn't get any shipping notification, so reverted to my weeky emails requesting updates. These produced NADA.

Then I remembered I'd paid via eBay so on 1st October I filed an 'Item not received' case - bingo! immediately I got a reply:
'Hello Sir Sorry to the late shipping. We will ship the two items this week. Please assist us to close this dispute. Thanks for your help and patience'
I replied with 'I will only close this dispute when I receive the items I have paid you for' and the next day came:
'Hello Sir We already ship the two items today. When you receive the package, please close to the dispute. Thank you
The shipment arrived 5 days later, so I closed the case - sure enough, it was a new control board along with 2(?) BMS cables.

It took me a few weeks to make time to attempt the control board change - life gets in the way sometimes....
This isn't a 5 minute job, so many screws! - but opening up shows:

It's secured by just 2 screws at the back (but use a magnetic screwdriver, if you drop one it falls into the guts) and copious amounts of glue on the cables/connectors.
Once removed, I thought it looked familiar and a side by side comparison with the new board showed they were identical - apart from pcb date codes, check for yourself:

Even the Microcontroller is the same:

As I said before, I was skeptical, previously I'd examined the removable control panel - to check out what the on/off switch did.
Turns out to be just a sp n/o contact via twisted pair 7/8 of the cable to/from the main board:
PIP Control Panel Cct Diag1_crsml.jpg
PIP Control Panel Cct Diag1_crsml.jpg (64.13 KiB) Viewed 2960 times
I was going to use a time switch and external relay to time switch ECO/Line off/on - but then I found SolPipLog.
This panel has all the BMS port components (connectors, opto's etc.) present.

After swapping the board I apprehensively fired up the PIP again and eventually, after changing from some of the default settings, all was working again :o
I checked menu 05 still had no PYL option and the firmware was 'only' 71.60 :evil:

So what was 'new' about this board? - I'd paid $60 for a firmware upgrade from 71.50 to 71.60.....

Worse - SolPipLog had 'lost' the inverter, no data was being sent to EmonCMS - because the new board had an un-programmed serial number '55355535553555', which SolPipLOg uses to ID the feed.
More emails to MppSolar 'support' produced a link to download 'AxpertSetSN' - which was useless, no way to enter/change the s/n....
Yet more emails produced new downloads: 'communication-tool'
My first attempt with this program failed - the Axpert tools are very fussy about serial port number/types etc. and the state of the PIP when you try updating firmware.
Examining the instruction pdf showed using ATE1 and the SID command to program the ID location, and using these in the SolPipLog debug window worked and the new board now had the a correct serial number - EmonCMS statred logging again.
But still no BMS support, so more emails and by early November I received a link to a 'slew' of downloads to update the firmware - whoopee!
This took a while as again it had to be low priority job, but eventually I had a go following the instructions, but it ended in a failure.
So I powered down the PIP completely (I have a c/o contactor (relay) on the PIP output so I can bypass it externally and an isolator on it's input) both these off and ran it just off the battery.
I also used an old PC with a 'proper' serial port set as COM1.

The updating programs took a while, but eventually I had a PIP with firmware 71.86 and v2.00 of the front panel up and running - now with a PYL option in Menu 05 :)
That night I saw that the midnight-1pm (SolPipLog time switching reduced it from 1hr to 10 minutes) switch to grid was gone.

Conclusion: maybe pre-2019 MK's aren't obsolete? they CAN take the latest firmware....
You can spend a few months emailing MppSolar for a 'new' board costing $55 or have a look at the installed control board and compare it to the pics of mine.
Then take a punt at re-flashing.

Hopefully in the next week or so I will get the opportunity to re-fit the 'old' board and try flashing weber/coulombs patched firmware.
Cheers :D

Hi @weber thanks,
Water under the bridge, hopefully others can avoid getting their feet wet :)
I PM'd @coulomb to ask if the 71.86 firmware and other stuff was of interest - no reply as yet.....
It's a shame Axpert don't publish update/change info with the new firmware - I've no idea what 'improvements' are in 71.86 over your 71.80.

Thank you very much.

Since there is a hint at the download:
Do not use with clones, only with genuine Voltronic Power manufactured machines. Otherwise, fault F90 is likely after a couple of months of runtime.

Will I get this issue when flashing a 5048MK with this firmware?

The machines sold by MPP Solar, including the PIP-5048MK, are manufactured by Voltronic Power. They have simply been rebadged. So you will not get this issue.

Helloooo.

Soo my brand new parallell PIP5048MK arrive. And problems arrive with them
:( .
First. Seller forgot to send me parallell boards. Wait 1 week more to send me new parcel with parallell boards.
1 week later parallell kits arrive. I start to install inverters.
And voala :( second problem.. Fault code 72. Start to check all conections.. Cables and etc.
All is OK. But only 1 inverter provide power to loads. And again fault 72
Start to measure. 1 inverter not have any voltage in output.

Contact seller.. Then contact MPP Solar support team.
They send me instruction how to open inverter and to change Contr. Board from 1 inverter to other. To check what will happen.
I open inverter and... :roll: surprice.. See what found inside.

Bad assembled Brand new inverter.with disconected cable and damaged board.
Conect brown cable to place. And now output voltage is OK

Connect all cables. Parallell boards and etc.
And new surprice
Inverters always take power from grid. No matter day or night.
In sunny day with lot of Power from PV array. Inverters use always around 200w from grid.
Try with any possible settings.. Not possible to stop using power from grid.
In fact for all day if i use 2000W power.. All power is taken from grid.
I am very dissapointed from this PIP5048MK
Not have sence to have 6000w from PV array. And to use power from grid.
Again contact MPP Support.. Now wait for answer.

Did any PIP5048MK user found some way to stop inverters to pull power from grid??

Thanks in advance for any help or idea.

Welcome to the forum.

My guesses are wrong serial port selected (check which COM port your USB to serial adapter is using), pirt is COM10 or higher, or the USB to serial adapter is not compatible.

hi,

the serial port in Windows is com3 and the Software provide com3. When you look at the attached picture, you can see the communication between Software and WR shoud be work. When i push the flash button in the Axpert Reflash, the WR display show UPG YES. 10 seconds after error code in the Software, the display looks like before.

OK, but are there other options in the drop down list box? My laptop, for example, has two COM ports (5 and 8) that are always present, called "standard serial over bluetooth", that are not my serial to USB adapter. The Reflash Tool has no way of knowing which port is the correct one, and will just pick the first one it finds.

Please check the generic instructions (for PIP-5048MS models, make some adjustments) here. (Also ignore the files there.)

What USB to serial adapter are you using, and what cables?

Does WatchPower work over that adapter?

It looks like it wants you to push a button on the inverter's display unit, possibly the one beside the word "YES", to confirm that you want to upgrade. However that isn't mentioned in the Axpert-King/PIP-MK-specific instructions from Voltronic Power that Coulomb posted here:

https://powerforum.co.za/files/file/48- ... -guidepdf/

Why not do the firmware upgrade directly from a USB-drive plugged into the inverter's display unit? That will eliminate the need for all this stuffing around with serial ports and adapters. This is described on page 23 (PDF page 25) of the inverter manual.
