MPP SOLAR PIP-7248MAX

Post by dRdoS7 »

Hi,

I was recently looking at duplicating my existing 5048MG, and found an Australian MPP Solar store. There was a new inverter: PIP-7248. Sounds like a better idea than 2 MGs for my purposes. Most I have needed recently, since putting the whole house on the MG, is 6000W (which caused the MG to trip to bypass mode). Only an extra $500. Less wiring, etc.

Be able to remove both the MG, & the Classic 200.

I ordered one myself. It will arrive in a few days.
My previous one was also a 5048MG.
I am curious how this new one will be.

I found on this Spanish forum someone who took it apart and reviewed it:

I understand it can be quite noisy....

It is noisy, has 3 fans (already changed to blow up, down blowing direction temperature raised over 50 degree celsius, up blowing it not goes over 42). It suffer from same pv freezing bug. I have already the latest firmware.

The noise won't be a problem for me, as it's in the garage, away from the house.

By "freezing bug", do you mean Error #08?

I haven't had one of those with the MG since I turned on grid charging.

I'd hoped they would have fixed that problem in the newer inverters.

No, this is where the PV power goes to zero until the next day or the SCC is reset. There are also the "dips" where the power goes to zero for a short time (minutes), but then recovers as if nothing had happened.

OK. Haven't read of that bug.

Don't think I'd want that inverter. Do the "dips" occur when off grid?

A second MG sounds like the better option!

The dips are on PV side, in case of an off-grid installation will it draw al the current what it needs at that moment from the battery.
But some others inverter type from same family due the same. I hope @coulomb will patch the firmware and get rid of this bug.

Maybe file a complaint /request to MPP Solar / Voltronic. If we all do that, they might release a firmware upgrade....

I've conversed with MPP Solar about the #08 Error of the MG, and haven't seen any action from them.

The faults with the MAX seem even worse.

Hmm, interesting, as there were updates addressing the #08 error. But as I understand you were not notified about that?

Well, I already ordered the Max and it will arrive Wednesday.
We can compare the firmware versions.
We'll see....

I did see an update, but thought that the error still occurred, in some cases. There was a work-around too. Both on the SA Powerforum.

No update notification from MPP.

Also saw this:
Factory firmware version 71.71 for PIP-5048MG / Axpert MKS II 5K-48. This is supposed to fix the PV dips and freezes problem, though we're not aware of any users that
On the first page of the MG thread. So it does have that same problem! I haven't seen it on my MG (71.20).

Updating this thread.
I was on firmware 45.01 and had all kind of weird bugs, but since I flashed 45.04 and display 12.03 the Max is behaving a lot better.

I didn't try the 90.xx series yet. Any of you did?
Antonio Battaglia of solarpower24.it offered to do a distance update through teamviewer.
He cannot just give me the file as Voltronic made it for him to support his batteries. Fair enough.
Curious which version that one will be.

Hello,

Do you mean they got Voltronic to patch to firmeware to get their LiFe4po batteries BMS handle by the inverter ?

Not me, but a user on the Powerforum has, with some success. See this post and several after it.

I suspect that the 45.XX firmware has been replaced by 90.XX, except for the PIP MAX 120 V models, which will have the same version as the 230 V models, except starting with 90.XX instead of 45.XX. For example, the 90.19 firmware, when running on 120 V PIP MAX hardware, will report as 45.19, and of course behave as a 6500 W 120 V model. (That's over 54 A AC output, ouch!)

Edit: However, they don't seem to have settled on the numbering scheme until recently. For example, 90.11 reports as 50.00 on 120 V MAX hardware.

Yes, that's correct.
Curious, they just answer to me no bms support for their batteries on their voltronic inveter. :roll:

BTW I will be interested in getting the capture of the messages that the inverter is exchanging with the pylonthec, in order to determine which parts of the pylonthec rs485 battery communication protocol specification are really used.

He told me the wall version of this battery has bms communication support with voltronic inverters, the rack version does not due to a different bms used.

Yes, my supplier confirmed the 90 series are the latest ones.
I had no problem with 45.04, (except for a small bug that the load W was not always displayed with small loads) but I am off-grid.
I flashed 90.11 yesterday and my batteries were much lower this morning than with 45.04. Not sure if that is coincidence or not.
I will now flash 90.19 as I didn't see that update until now.

Voltronic Power Axpert MAX 7.2k Details

Post by derBastler »

[ Moderator note: the next 7 posts were merged to here from another topic. ]

Because the device has not been discussed further here so far, I would like to show you a few details about the Voltronic Power Axpert MAX 7.2k. The device is sold in Europe for about 1000€ by different brands. My device comes from the brand Alpha Outback Energy (Axpert MAX 7200-48-230. In the following you get the following infos

-Technical details
-Pictures
-Manuals
-Software on the CD
-Firmware that I found

Technical details

- 7200W AC Power
- 8000W Solarpower with MPP-Trackers, max. 80A and max. 450V
- Battery Voltage nom. 48V (Max Charge 62V, Min Discharge 44V)
- Max. Battery current 80A (settings: 2A, 10A, 30A, 40A, 50A, 60A, 70A, 80A)
- Dimension, D x W x H (mm) 147.4 x 432.5 x 553.6
- Net Weight 18.4kg
- Communication Interface USB/RS232/RS485/Wifi/Dry-contact
- IT HAS RGB!!!!! Everybody waited for this, didn’t you?

The inverter comes from the factory with Wi-Fi and you can connect it to some Chinese server with the apparently new Watchpower app. The app is a total disaster and super insecure. You only need the ID, which is at the bottom of the small display and you have full insight into your inverter. Typical Voltronic. The guys can't do software.
Overall, the thing makes a good impression. Especially the two separate MPP trackers could be useful for some. Up to 6 of the devices can be connected to a 3-phase grid. You have the usual choice whether 6x1 phase or 2x3 phases.

I can confirm that this appears to be a genuine DSP firmware for Axpert Max, version 45.06. This is moderately old now, so of little interest. There is a folder for updating the removable display, but it has no firmware file. Worse, when I run the updating program, it complains that it can't find dsp.hex (after I definitely pressed "Update MCU"). [ Edit: that seems to be a typo in the program; they all seem to do that. Sigh. ] My suggestion is to ignore that download.

I'm not familiar with this particular Axpert, because we have a much smaller one, but the za guys know plenty about the Axpert range, and one of them has made complete monitoring software you can run on a RPi.
Their forum https://powerforum.co.za/
Alternate software https://iccsoftware.co.za/
This is far far better than the Watchpower one supplied. I've tried both.

:D thank you coulomb, the sad thing about this is that the firmware comes directly from an official support guy. What a crappy update support.
