Can I Update My Firmware?
And If So, To What?

This is becoming an increasingly vexed question, especially with the various resellers naming their products in confusing ways, the profusion of models available, and the fact that in certain circumstances, including an increasingly common one, it is possible to brick your inverter if you get it wrong.

Exclusions
First, I need to eliminate models that won't be covered in this post.
  • Any model with a rated apparent power other than 5 kVA.
  • Any model whose maximum PV voltage is greater than 145 V. Check the label on the side of your inverter.
  • Any model with a PWM Solar Charge Controller (SCC). See the zoo post for clues on whether you have a machine with a PWM SCC.
  • Any non-genuine clone or work-alike. Some clones don't seem to be firmware updateable, some are. See Do I Own a Clone?

The above has the wrong SCC maximum voltage to qualify for this post; it should state "145VDC".

The starting point is the existing firmware version. Find it by pressing the up button on your front panel, till you get to a screen like this:

U1 74.10.jpg
U1 74.10.jpg (31.12 KiB) Viewed 3031 times

There is an implied decimal point between the middle and right groups of digits, so the above represents main (DSP) firmware version 74.10. The number before the implied decimal point (the digits in the middle group) I'll call the major version number. The right group I'll call the minor version number (even if it includes a letter). If you've installed patched firmware, the minor version number will in fact end in a letter (e.g. 73.00d).

Now you can follow the decision tree below.

In what follows, the X and Y represent digits, and the represents a letter.
The "64 V option" refers to models that allow the float and absorb/bulk settings to be set as high as 64.0 V, and the battery-side circuitry is upgraded to allow this to happen safely. Do not assume that because you have the latest model, you'll automatically have this feature. It's up to the supplier whether they provide it or not, and whether they indicate this capability in their model numbering. As a special case, MPP Solar will only offer models with the 64 V option, if that model is manufactured at all.

If your current firmware has a major version number of:
72:
  • If the current firmware minor version has a letter at the end then
    • Congratulations! You're already running patched firmware.
      If you're currently running 72.20 then
      • You can update to the latest 72.YYℓ, (YY ≤ 20!) if not already running it.
      Else
      • You can update to patched firmware 73.00 or 72.XXℓ, (XX ≥ 40) unless already running it. The only reason I know of to consider 72.XXℓ is that PB1_72.70b can be paralleled (parallel or 3-phase or both) with those 5 kW (PF1) models that don't have the 64 V option. Note that the LFP version of 72.70b and patched 72.70c or later (LFP or not) can't parallel with 74.XX due to changes in the value of settings that are communicated over CAN packets. You can also update to factory firmware 72.XX, if you trust the manufacturer more than a pair of enthusiasts, but then you'll be guaranteed to get the premature float bugs. This probably won't affect you if you don't use solar panels. The only factory firmware that will parallel with 74.XX is 72.70. Do not update to factory firmware 73.00 if your machine came with 72.XX from the factory; if so, you will run into error 90 after 60 days of runtime.
  • Else if the current firmware minor version is greater than or equal to 40 but less than 90 then
    • You are running older hardware, rated at 4 kW. You can update to patched firmware 72.XXℓ or 73.00. You can also update to factory firmware version 72.XX (but see the note above re the premature float bugs). Do not update to factory firmware 73.00 if your machine came with 72.XX from the factory; if so, you will run into error 90 after 60 days of runtime.
  • Else if the current firmware minor version is less than 40 then
    • You are running a 5 kW (PF1) model with the 64 V option. You can update to patched firmware version 72.20c or later. You can also update to factory firmware 72.YY, if it is a later version than what you have now. NOTE: YY must be ≤ 20! Otherwise, you will be attempting to downgrade to older PF0.8 firmware.
  • Else if the current firmware minor version is equal to 90 then
    • You may well have a clone. You can try to update it to patched firmware 73.00, where is 'c' or later.

73:
  • You are running a 4 kW model (PF0.8). You can update to 73.00, if you're not already running the latest patched firmware. There is no updated factory firmware for your inverter that I am aware of.
74:
  • You are running a 5 kW model, with the usual 58.4 V battery voltage limit (no 64 V option). There is no patched or downloadable factory firmware for your inverter that I am aware of.
  • For that reason, if you're considering a new inverter-charger, and 5 kW models are the only ones that you can get, consider insisting on one with the 64 V option, whether you have use for that facility or not. That way, there is patched firmware available, and if you want to go back to factory firmware for whatever reason, you have that option (all patched firmware zip files include the factory firmware that they are based on; to revert to factory firmware just rename the original .hex file to dsp.hex and run the reflash tool). MPP Solar sell the PIP-5048MS (64V) model through Ebay, and they seem to have at least as much technical know-how as other resellers.
75:
  • You are running a dual- or triple-MPPT model. These are not parallelable with single MPPT models, and the firmware is not interchangeable. You can update to patched firmware 75.31a, which only has the premature float bugs fixed, there are no other features, not even the LiFePO₄ voltage threshold changes. Even though this patched firmware has the highest major version number, it only applies to less popular models, and has the fewest features.
52:
  • You are running early hardware, rated at 4 kW. NOTE: some 4 kVA / 3200 W models have major version numbers equal to 52, but those are not similar, and they should have been rejected by one of the exclusions above. Despite being an early model, you can update to the same firmwares as you could if you had firmware with 72 before the implied decimal point (see the first entry in this decision tree).
71:
  • This usually means you have a model with higher voltage SCCs, such as the PIP-4048MG, which should already be excluded above. However, Weber received a replacement control card with 71.20, and it worked fine in a PIP-5048MS with 145 V SCC. He was able to reflash this to 72.20c, and it charged his battery from his 100 V panels just fine.
    If your SCC's maximum DC voltage is 145 V then
    • If setting 26 (Absorb/Bulk voltage) allows you to go to 64.0 V (not just 58.4 V) then
      • You should be able to update to patched firmware version 72.YYℓ, or factory firmware 72.YY (YY ≤ 20!).
    • Else (setting 26 goes to 58.4 V)
      • There is no firmware update available at this time.
When you're ready to install your firmware, use the index in the first post of this topic to find the appropriate update files, update instructions, and so on.

If you find problems with the above guide, and the inverter-charger model concerned is relevant to this topic, please post a question about it here.

The same way you sent the QPIGS command, except that it will require different CRC characters. Normally, commands would be sent from a program that can automatically calculate the CRCs, but you seem to be in the exploring phase where it's worth the effort to do this manually.

See the posts referenced from the first post of this topic (page 1), particularly the first two under "Commands". Both those commands have CRC characters with a sign bit set, so it's awkward to type them or to display here. Scott's CrcGen applet makes it easy to send commands, if you're using RealTerm.

But here they are for completeness, since you have TeraTerm set up, and it's sometimes tricky figuring out the key sequences from hex values. These are the commands to disconnect the master (machine 0) from loads, and to re-connect it, respectively:
MNCHGC0497 7 R-Alt+5 enter
MNCHGC0498 R-Alt+F Z enter
where R-Alt (usually the right Alt key) is the special key set up to send the sign bit with an ordinary character when running TeraTerm, and enter is the enter key (to send a carriage return). The corresponding commands for the slave (presuming you have just one) are as follows:
MNCHGC1497 A ctrl+a enter
MNCHGC1498 R-Alt+0 R-Alt+n enter

I hope I have the above correct; I don't have an easy way of testing them.

For other readers: these are extended commands, available only in patched firmware that have the Dynamic Load Control (DLC) feature. This allows an external program to almost but not quite turn off one or more paralleled machines to save power, and turn them back on when needed. Sending these commands to non-patched firmware, or patched firmware that doesn't have the DLC feature, will do no harm; the commands will merely respond with a NAK (negative acknowledge) instead of ACK (positive acknowledge).

[ Edit: added "when running TeraTerm". ]
[ Edit: Added text to say what the commands do. ]
[ Edit: had wrong CRC char (# instead of the correct 5) for first command.]

You can look up the CRC for any PIP/Axpert command by typing or pasting it into the Sunshine online CRC calculator and clicking the Calculate CRC! button. You first need to choose:
  • CRC width: CRC-16
    CRC Parametrization: CRC16_XMODEM
    CRC Input Data: String

For MNCHGC0497 it tells us the CRC is 0x37B5. But we can't simply type this into Tera Term. This is a hexadecimal value. We need to convert it to a pair of characters. We ignore the "0x" and split the rest into two parts: "37" and "B5". We need to find the ASCII characters that correspond to these.

We can use this ASCII converter. We first type "37" into the "Hexadecimal" box and click the Convert button below it. Then "7" appears in the "Text (ASCII/ANSI)" box. So "7" is the first character we will need to type after the command.

Then we replace "37" with "B5" in the "Hexadecimal" box and click the Convert button. This time the "Text (ASCII/ANSI)" box is blank. That's because the hexadecimal number "B5" doesn't actually correspond to any ASCII character. But that doesn't matter. TeraTerm still lets us type it by holding down the right-hand Alt key while typing a character. To find out what character, go to the "Binary" box and change the first "1" to a "0" and click the Convert button below it. Then "5" appears in the "Text (ASCII/ANSI)" box. So "5" is the second character we will need to type after the command. But we must hold down the right Alt key while doing so.

In total, we must type:
M N C H G C 0 4 9 7 7 right-Alt+5 Enter

It should be understood that you need to hold the shift key when typing characters such as "M" above.

But Tera Term must be set up correctly, for the right Alt key to work in this way. If you haven't already done so, you need to edit the file TERATERM.INI. To open this file, launch Tera Term and choose the menu item Setup->Setup directory… then click the top File button. Search within the file for "Meta" and ensure you have "MetaKey=right" and "Meta8Bit=raw". Save the file, then exit Tera Term and re-launch it, so these settings take effect.

Similarly, MNCHGC0498 has a CRC of 0xC65A, and we can type that in Tera Term as:
M N C H G C 0 4 9 8 right-Alt+F Z Enter

There is one more thing you need to know about PIP/Axpert CRCs. If the hexadecimal value of any CRC character is 0A, 0D or 28, you must add one to it before you do the hex to ASCII conversion. So these become 0B, 0E and 29 respectively. This is because 0A, 0D and 28 correspond to the ASCII characters <line-feed>, <carriage-return> and "(", which have special meanings in the PIP/Axpert serial protocol, and so must be avoided in its CRCs.

And there is one more thing you need to know about hex to ASCII conversion. Some hex values do not convert to a keyboard character, even after changing the first binary digit to 0. If the hex value is 20, type the space bar. If the hex value is 7F, type the Delete key. If the hex value is in the range 00 to 1F, you will need to hold down the Ctrl key while typing another key. To find the required key, you can look up the hex value in this Control Characters table.

We have just bumped patched firmware 73.00e (the first with kettle compensation) from beta to release.

Many thanks to all who tested the beta version.

Sucsess!!

I am doing this via TeamWiever to the remote pc, i just had to use a ENG/USA screen keyboard.
Did not work with Norwegian keyboard layout! :mrgreen:

My total system use is 28-30w when the 5048ms inverter is disconnected from loads. VS 76w when on.
That is a intel nuc-pc, 13.3 Lilliput touchscreen monitor, Asus 4G-AC53U wifi router, , and a W1209 with 2 Noctua NF-A12x25 fans, all running from a 48v-12v DC reducer.
I am waiting for a 12v-5v dc reducer for my webcam and weather station.

Hi all,
I have been searching for help with my inverter and found this forum with useful information thus registered and this is my first post:

I purchased an EASUN SM-5K inverter in July 2017 (Voltronik produced). The unit was modified by EASUN so that I could adjust charging voltage to 64V (since I need 58.8V for the BMS of my 14S lithium power wall).

All was running fine for more than a year.
2 month ago I changed the monitoring PC to a Windows 10 system and installed a newer version of whatchpower (but I hope this has nothing to do with my error).

One night something happened and the inverter was switched off in the morning.
On restart I get:
Error Code 90

Inverter beebs for 2 min and then switches off again.

Error 90 is not documented in my manual, but I found some mentuonings here referring to firmware issues.

There was never anything attached to the RJ45 serial so far ....

Any help how I can start debugging the unit would be highly appreciated !

Thx,
Thomas

Welcome, Thomas.
I purchased an EASUN SM-5K inverter in July 2017 (Voltronik produced).
I'm not familiar with that brand. Are you sure it's a genuine Voltronic? Could you post a photo of the label on the side, including the small date of manufacture sticker if there is one?

I note that at the bottom of http://www.easunpower.com/, I find the words "Copyright © 2016 MUST EASUN INDUSTRIAL CO. LIMITED". "Must" is the brand of the original illegal clones. Maybe they are a legitimate reseller now, and the photos on the page look like genuine Voltronic Power models, but it's quite suspicious.
The unit was modified by EASUN so that I could adjust charging voltage to 64V
Are you saying that they made changes to it after manufacture, and that it came out of the factory as a 58.4 V model? I've never heard of that modification, and I wonder if they actually replaced a bunch of MOSFETs and capacitors, as well as whatever else would be needed.
(since I need 58.8V for the BMS of my 14S lithium power wall).
You really need to charge to 4.2 VPC, 4.1 VPC would not be enough? But that's all done now.
All was running fine for more than a year.
That's interesting, because fault code 90 (error 90) usually comes up after 60 days of running time. Does your machine spend a lot of time switched off?
2 month ago I changed the monitoring PC to a Windows 10 system and installed a newer version of whatchpower (but I hope this has nothing to do with my error).
I would think that it would have nothing do do with the error. But two months is 60 days, so it's suspicious.
Error 90 is not documented in my manual, but I found some mentionings here referring to firmware issues.
Presumably, you read the section in the index titled If you find your inverter charger stops with error 90. Since this is a firmware issue, please tell us your inverter main firmware. I hope that you can still use the up button to cycle through information screens, even in fault mode (before it switches off, so be swift), and report what comes after "U1".
There was never anything attached to the RJ45 serial so far ....
So you've never updated your firmware, though EASUN presumably did during their modification.

Hi Coulomb,
Since I have 14S BMS with passive balancing per 168 LiIo cell blocks (14S12P) the main balancing happens close to 58.8V.
So I contacted EASUN what the max setting value is and they stated 58.4V but for 30$ extra they can provide me a 64V capable modified version of the inverter.
I had to wait a few weeks longer but the unit arrived and I could set Umax to 58.8 (and higher). I had the feeling up and down button was swapped, but everything was working nicely.

I have taken photos of the unit but still need to figure out how to post them (will do once I figure it out).

But most importantly: Yes, I can go up and down while error 90 is beeping!
Behind U1 it states 72 in the middle and a 00 on the right.
I can also cycle to all other display modes.
I can see my Batt voltage (currently 56.8V) but all other values are off/empty,

Thx for your help already now, pictures are coming!

Rgds,
Thomas

Only thing I have is the IMG button to include a URL to an Image.
Red a few older posts and I beleive my account is not yet configured to be able to upload to the AEVA server.

Hope someone can enable me. In the meantime trying to find a public Picture upload possibility.

There seems to be a glitch in the forum software. You should be able to add attachments including images now. Sorry about the hassle; I'll talk to the more experienced admins about this to try and get it sorted for all new users.

Hello everyone and a happy new year!

I own a hybrid charger/inverter sold in Romania as E-SOLARE 5KVA / 48V (+80A MPPT - max 4000 Wp - 60/72 cells). The device was new and it worked great for the first 3-4 months, after this the inverter randomly restarts even without any load and without any error code, not even in watchpower logs. In the device menu the error logging is enabled.
The first thing i tried was to check and clean all the connections, but this didn't changed anything. After reading about the capacitors problem in these devices, i'm worried that they could cause this and it's a matter of time until something worse will happen. I didn't managed to find any correlation between these restarts and SOC or inverter load.

Did anyone faced this issue?

Also i would try to update the software, but i'm not sure which one to choose. The device came with 72.40.

Thank you very very much,
Marius.

EASUN Isolar SM5K-64V product label:
That looks to be quite genuine. Is there a small sticker with 2017 and twelve squares with square 9 blacked out?
Internal view:
That looks genuine too.
Can this be positively identified as a Voltronic version ?
Not really, but it seems very likely it's genuine.
Can I use the firmware update to get rid of error 90 ?
I think you can. There is a special check in the fault mode firmware code that disables the switch-off after 30 seconds if the reflash sequence is seen. You'll still have to be quick, starting the reflash very soon after the unit is powered up. So I think you can update to factory firmware 72.20, or since you've opened your case and possibly voided the warranty, you could go for patched firmware version 72.20c (or wait a week or two for 72.20e). I think that maybe there is something wrong with factory firmware version 72.00, such that it doesn't avoid error 90 properly. I've heard of a purchaser who insisted that s/he update to version 72.20 as a priority. You would be within your rights to request a firmware update to fix this, it seems to me. See the index in the first post of this topic for upload instructions, links to the patched firmware download, and how to reflash with the factory firmware if that is your choice.
Any other check I should do ?

I can't think of any.
On a visual inspection all components look absolutely fine ... No smell, nothing ....
Yes, error 90 fortunately does not refer to a hardware issue.

Good luck, and let us know how it goes.

Hello everyone and a happy new year!
Welcome, Marius.
I own a hybrid charger/inverter sold in Romania as E-SOLARE 5KVA / 48V
It appears to be a PIP-4048 or similar, with a different reseller. If so, that's not what we call a hybrid; it's an off-grid inverter-charger.
Did anyone faced this issue?
I've certainly never heard of it.
What does the small yellow sticker above the larger sticker with the bar-code say?
It's unusual to see an 80 A MPPT with the heat-sink on top. So I'm wondering if it's a genuine Voltronic Power model. Usually the capacitors drying out don't cause an issue in the first year or two, unless they are very cheap parts.
Also i would try to update the software, but i'm not sure which one to choose. The device came with 72.40.
I wrote a post specifically about that question: Can I update my firmware, and if so to what?

Yes there is (was ... Since I opened the case I ripped it in half):

Thx a lot for all the very valuable information !
Ordered a PL1303 USB to DB9 cable now and when it arrives from China I will attempt to update to 72.20e.
Will let you know !

Another quick question:
To check the USB-RS232-RJ45 setup before updating firmware, can I simply run watch power on the PC and see if it finds the inverter via serial link ?

Thomas

Thanks coulomb, sadly the device is in another location, but with the first chance i will take a few photos of the stickers.
PS: now that you've mentioned about the heatsink, i'm sure that mine doesn't have it on top. I used a pic from the sellers website for that model, because the single photo i have is the one with the specs that i posted, but i didn't noticed that until you pointed out.
Anyway, i'll get back with more pics.

Thanks again for your time,
Marius.

Yes, that's a good sanity check (don't forget to exit WatchPower before the re-flash, not just close the window). That won't guarantee that it will work with the reflash tool, but it's a great indication.

@mariusvaida hi, what do you have there, is a clone. I doubt you will be able to flash it. I have also two of this clone, tried to flash without success. I can't send personal message, it's brand new registration on this forum.

Do you refer to my EASUN unit?

Do you have EASUN units, too?
Would be great to share details.

I believe he was referring to Marius' E-SOLARE 5KVA, as sold in Romania.
