Good afternoon all,
Welcome.
Set up the master no issues, as soon as I turned on the slave it alarmed and the fault light came on.
So both are independently set to PAL mode (setting 28)?
Is there any fault codes you can access?
When the fault light is on, and the "ERROR" indicator is on to the right of the middle two digits, the two digits in the middle are the fault code. Fpr example, in the attached, it is indicating error/fault code 71, which you look up in the Parallel Installation Guide because it's an error specific to paralleling machines.

Can you quote that number please? Or are you saying that the LCD doesn't come on?

[ Edit: Error 71 means "Firmware version inconsistent". You have to have the same or "compatible" firmware revisions in the master and all slaves. If the version numbers are identical in the first four digits (e.g. 72.70 on one and 72.70A on the other), then they are definitely compatible. It seems that otherwise if the are in this set, they also should be parallel-compatible: { 52.30, 72.40, 72.60 [ edit: and 73.00 ] }. What are your main (U1) firmware versions? ]
Hi Coulomb, when i went to look for the error codes 71 did come up but only after i pushed the up arrow a couple of times. While doing this the error light went off and i was able to set up the slave unit, all good now i will check the firmware versions, about a year between when i bought them.

[ Edit reverted by Coulomb: should have edited the original, not this quote of my original, as I have now. ]

What happens if you disconnect the master from the battery and start up only the slave? Does it still have a fault?
Hi Weber,
I tried that and it didnt work, but for whatever reason it is working now.

Hello, im alessandro from italy, i ve a problem with my pip4048.. It fail to switch to grid, i hear te "TAC" but it remains on battery and it keeps trying to swich 10-20-50 times until it works.. If not works after a x number of times it give up and leave the battery discharging!
Last week i found my poor battery at 33v!!! And today my 200ah battery pack was discharging at 80A because pip 4048 failed to bypas to grid!!!!
I dont know what to do, how can i fix this issue?
Thank you!

Hi, Alessandro. I assume by "TAC" you mean the clicking sound of a relay turning on or off.
but it remains on battery and it keeps trying to switch 10-20-50 times until it works.. If not works after a x number of times it give up and leave the battery discharging!
When it fails, does it give a warning at all? A warning will show up on the LCD (display) as a warning icon beside the central group of two digits, an exclamation mark ("!") inside a triangle. The digits and warning icon will be flashing.

Also, are you seeing the "AC present" icon? It looks a bit like a tennis ball; a dark sine wave inside a light circle.

Does the AC present icon go away briefly after a failed attempt to switch to line mode?

Is it possible that you have poor mains somehow? Perhaps the voltage is very high or low?

Could there be excessive resistance in the AC cables?

Are you perhaps using a generator as the AC source? These inverters are very fussy about the quality of the AC input, since they have to synchronise with them.
Last week i found my poor battery at 33v!!! And today my 200ah battery pack was discharging at 80A because pip 4048 failed to bypass to grid!!!!
That's not good for lead acid, and the 33 volts is bad for any kind of battery. My guess is that as soon as the inverter changes from battery to line mode, the AC source under load is measured to be bad in some way (perhaps low or high voltage or frequency, or perhaps noisy zero crossings) and the machine immediately switches back to battery mode to keep the loads powered. But the inverter should be disconnecting way before the battery reaches 33 volts. Check setting 29 (low DC cut-off voltage).

It may somehow be a battery issue. Is the battery old? How much does its voltage sag under say a 2400 W load?

- no warnings, no triangles, nothing..
- AC is present and it is always between 200-245v in worst cases, most of the time is about 235-240v, 200v only with 3kw+ loads only in some rare cases.
- i dont now, i think not.... cables are for 6kw and not too long
- no generator

i have 8 100ah AGM batteries 1 year olds, i set cut-off to 42,5v and machine seems to fail the switch, not switching to grid and then switching back to batteries..... i hear the rele but on the lcd nothing happen, also batteries discharge current doesnt go to 0. so is not switching at all!
maybe im wrong, but AC input is good and no warnings shows up.
It may somehow be a battery issue. Is the battery old? How much does its voltage sag under say a 2400 W load?
i dont knows what you mean for "voltage sag", also google translator doesnt know :(
maybe you mean how much the voltage drop when you put the battery under load?

edit: ok you mean that.... i tried and from 48.3v with 400w load, batteries drops to 45.9v if i apply a load of 2,3kw

edit2: now it works properly... tested 2-3 times and it switch at the first try. since when the issue happen i have heavy loads connected, maybe is right what you say.... with 3kw+ AC input drops immediatly to 200v or even less and the machine switch back to batteries. i have to set appliance voltage range instead of UPS.
remains the problem that it ignored the cut-off voltage and discharged the batteries to 33v, that is the worst problem.

I have a pip4048 inverter . since yesterday I have a problem with the photovoltaic charge. the inverter, even if disconnected from the panels, always signals 53v and 1A of charge. I disconnected the cables but always remains in solar charge even at night. reverse has the firmware 72.60 and 4.10 date 2016. the problem can be software? Is the charger broken? thank you

Good afternoon all,

First off I have learnt a great deal from this forum, thanks. At xmas I bought a second 4048ms, been running one for a year no issues. Connected the second one up today. Paralleled the batteries and the output, no pv's connected. Set up the master no issues, as soon as I turned on the slave it alarmed and the fault light came on. Is there any fault codes you can access?
Triple checked all the parallel connections and they are correct to drawing.
Any ideas. I have emailed my solar.
Thanks
Update, after sitting down and having a beer, i decided to go check for a fault code and it worked fine this time! Only thing i did different was switch off the breakers on my ac outlet side.
The instructions for the 24v parallel kit:
Line 1 in bold type DO NOT TURN ON AC
Line 10 on the instruction sheet reads:
Make sure the master reads HS and all the other units in parallel read SL. If all are not as describe repeat the steps from 1 through 9
Line 11 reads:
If all above is correct turn on AC

It doesn't actually mention AC in or AC out so I'm assuming they mean all the AC circuit breakers.
As you now have the system up and running once the AC was turned off it seems this may have been the cause of the error code. Maybe it was still in the process of matching the voltage, frequency and wave pattern between master and slave.

If you mean is it possible that the firmware (software running in semiconductor, i.e. hardware, memory) could have gotten itself corrupted somehow, yes certainly. It's a pretty complex piece of software, with 8 tasks running pseudo-simultaneously on one processor, and there are many areas which have to be protected by turning off interrupts or other safeguards, and it's entirely possible that they overlooked one or a few such places.

So yes: it's worth restarting the firmware by disconnecting the battery (and AC input if it's a very old model), waiting a few seconds, and starting again.
Is the charger broken? thank you
My initial reaction was that It's possible that if the above doesn't fix the problem, that the Solar Charge Controller (SCC) may have failed, and that perhaps you could have it replaced without replacing the entire machine. However, upon reflection, this can't be the case, since the SCC is only ever powered by the PV inputs. (I'm assuming an MPPT model here; the PWM models may be different). So to see a non-zero PV voltage reading at night or with the PV input disconnected rules out the SCC as the sole problem (again, assuming that it's an MPPT model, such as the PIP-4048 MS, not the PWM based PIP-4048 HS).

A few recent problems mentioned on this thread have "come good" after a period of time. Is yours one such?

Good Afternoon all,
I have been watching and reading this thread almost from the start and am truly impressed by everyone's efforts to reverse engineer the schematics and firmware of these units.

I am tempted to purchase one of the PIP units for an off-grid property but would first like to perform testing at home with on-grid mains power available. Just to get past some of the quirky issues people seem to be having.

For the off-grid property we are currently using APC SmartUPS 3000VA units with 14kWh of VRLA batteries and external MPPT chargers so we would have these to fall back on. The APC units have ~100w no load draw on the DC bus. We are planning to move to LiFePo4 batteries sometime this year.

So now the questions:
My understanding is that these are certified as approved for on-grid and grid-feed connection, is this correct?

What is the real world difference between the PIP-4048MS PF0.8 and the PIP-5048MS PF1.0 other than just the writing on the package and brochure.
Are they truly 20% more efficient?
Do they really deliver 5000w?
And, most importantly, do they work with the patched firmware that was written for the PIP-4048MS?

Other than being a single self contained unit with higher output, would they really offer any advantage over the UPS for off-grid use?

I notice in the Black Monolith images I could not see an earth-neutral bond in the AC box, do these have a floating neutral or was the bond in the main electrical distribution board?

The off-grid site uses a genuine Chinesium 6.5kva AVR type genset, one of these clones, so the output frequency will vary slightly depending on load, people seem to be struggling with this, what are the chances of making the PIP's tolerant of 50-ish Hz instead of exactly 50Hz?

And finally a little off topic but, where does one find purchase and pricing information on the LyteFyba BMS? I have not seen any mention of them on Lithium Battery Systems' site.

That's enough questions for now, thanks.

Jordan.

Hello,
Im a new on this forum, and French.
I thanks for this, because in France, there is no lot of news.
I have update my firmware 52.28 to 72.70c, it's OK.
But - I would like to do : 220V-230V-240V, because since 2014, only 230V.
- I would like equalization my battery crown CR220HD

Sorry for my bad english.

Interesting; perhaps they set it to 220 V at the distributor, or the factory.


The V220 etc commands have been shown not to work.
I was confusing a setting for "inverter voltage" with one for "output voltage".
The V commands appear to be a legacy from earlier versions or earlier products;
the setting changed by them isn't used elsewhere.
I've since found the correct command, and Weber is kindly beta testing it for me.
See this post for the correct command.


As far as I know, the output voltage setting procedure is not documented at all. My research indicates that you have to send it a "V220" command to change the output voltage to 220 V. Similarly, V230 and V240 for 230 and 240 V respectively.

So you need a computer with a serial port (these days that means a computer or phone with a USB port and a USB to RS232 adapter), and a communications program capable of sending 8-bit characters. The 8-bit characters are required for the CRC characters that are needed at the end of each command.

See the end of this post for setting up Tera Term. Note: to enable 8-bit character transmission, you need to find and edit the initialisation file, as per the instructions in the linked post.

Alternatively, this post for calculating the CRCs and pasting the command with CRCs as hexadecimal into the clipboard for you. Use with RealTerm.

Using Scott's Windows app, merely type V 2 2 0 enter into the app, and paste it into RealTerm followed by enter.

Not using Scott's app but having set up Tera Term, enter the following:
V 2 2 0 right alt+, right alt+shift+C enter

You should see an "ACK" response (no quotes), and not a "NAK". The "ACK" or "NAK" will be followed by 2 weird characters, being the checksum characters.

Edit: I am not in a position to test the above, so I have have slipped up.

Edit 2: I you were running WatchPower, you'll have to exit it (not just close the window). If unsure, see the how to update firmware post for exactly how.
And I would like equalize my battery crown cr220hd.
Check the user manual (first item in this thread's index on page 1) page 30 for details. Note: you can't get beyond 58.4 V for the "bulk charging voltage" (absorb voltage) setting (setting 26). You will need to find the equalise voltage for your particular battery, and it may be more than that limit. If so, the best you can do is to use the maximum allowed, and either extend the equalise time a little, or equalise a little more frequently, to compensate.

Edit 3: Unfortunately, I didn't have time to test this, and Weber points out in the post after next that this doesn't work.

Great post Coulomb, about the undocumented V220, V230 and V240 commands. A model of clarity. Except for one problem. They don't work. :) At least, not on my inverter.

BTW, the PIP never shows ACK or NAK followed by 2 weird characters. It always shows:
(ACK9
or
(NAKss

And I note that your TeraTerm key sequence should have a shift with the right alt and C, i.e.
V 2 2 0 right alt+, right alt+shift+C enter

But it still doesn't work. I get an "(ACK9" alright. But the voltage remains at 230 V. I've tried doing it after turning off the switch at the bottom of the inverter, as you have to do when changing parallel mode. I've also tried it in both parallel mode and single inverter mode. Same every time. It ACKs it, but nothing changes. Same goes for "V240". So maybe there was a good reason it wasn't documented.

Welcome, Jordan. Thanks for the kind words. I note that by far the bulk of that work has been done by Coulomb.

Very wise.
So now the questions:
My understanding is that these are certified as approved for on-grid and grid-feed connection, is this correct?
No. Not at all. Not sure how you got that idea. They are not even capable of feeding power into the grid. They are not on the CEC approved list at all, although the equivalent rebadged Giant Power IPS-4000WM is. But non grid-feed inverters do not need to be on the CEC approved list to be legal. Just don't expect to get any STCs for PV systems using them.

My understanding is that they are perfectly legal to use in Australia, provided all the relevant installation standards are adhered to, including AS/NZS 3000 Wiring Rules, AS 4086 Batteries and AS/NZS 5033 PV arrays. To comply with the latter, any connected PV array must have an open circuit voltage not exceeding 120 V DC at the lowest operating temperature. This is for safety reasons, because these inverters do not have insulation monitoring or earth leakage detection on their PV array inputs.
What is the real world difference between the PIP-4048MS PF0.8 and the PIP-5048MS PF1.0 other than just the writing on the package and brochure.
Are they truly 20% more efficient?
Do they really deliver 5000w?
I have never tested one, but I fully expect they will really deliver 5000 W. They are heavier. They do not claim to be 20% more efficient. I expect they are about the same efficiency at the same power level. You need to read up on the difference between VA and W in AC circuits.
And, most importantly, do they work with the patched firmware that was written for the PIP-4048MS?
No. I thought we had made that clear in several posts recently.
Other than being a single self contained unit with higher output, would they really offer any advantage over the UPS for off-grid use?
Other than that, no.
I notice in the Black Monolith images I could not see an earth-neutral bond in the AC box, do these have a floating neutral or was the bond in the main electrical distribution board?
The MEN link was in the main switchboard, as usual.

At this time, we have no idea how this might be done, and are not investigating it. But do be sure to set parameter [03] to APL, not UPS.
And finally a little off topic but, where does one find purchase and pricing information on the LyteFyba BMS? I have not seen any mention of them on Lithium Battery Systems' site.
Coulomb and I might be brilliant engineers :geek: :ugeek: but we are lousy salesmen. :D It turns out LBS were interested in using them in their own products, but not in selling them separately. They have left such sales to us, and have now handed production back to us. We are very grateful to them for getting the ball rolling.

Re: PIP-4048MS inverter

Post by weber » Thu, 08 Feb 2018, 13:56

Here's a brief explanation of the practical meaning of the difference between inverter ratings of 4 kW/5 kVA and 5 kW/5 kVA.

1. AC appliances that have some kind of heating element, and those that do not contain motors, typically draw the same amount of VA as W. These are called resistive loads.

2. AC appliances with motors, and old style fluorescent tube ballasts, can draw up to 50% more VA than W. These are called inductive loads.

If your heaviest loads are all of the first kind, you will care most about the W limit of the inverter, and so the 5 kW/5 kVA inverter will be of benefit.

If your heaviest loads are mostly of the second kind, you will care most about the VA limit, in which case it doesn't matter which inverter you choose, and your decision might be based on other factors, such as the patchability of the firmware.

Thanks Weber,
That has cleared up a few holes and fuzzy spots in my understanding.

I remembered reading that the Giant Power units were approved and mis-understood the full meaning of this.

We purchased our solar panels 2nd hand so we're not expecting STC's anyway.
No. I thought we had made that clear in several posts recently.
Sorry about that, I caught mention of it but lost track of all the different models and which are or aren't fully supported by the patched firmware, hence the question to clarify.

Thanks for the summary of kVA vs kW that sums it up nicely.

Once I get my design finalised I'll shoot you an email for a quote.

Thanks again.

Thanks for reply.
But the watchpower know to change 220V-230V-240V, I have a friend have 5kva more recent and He can select Vout on watchpower.
If I change the firmware SCC, no change ?
For equalization, crown CR220HD is 2.7V per cellulle, that 64.8V. So 58.4V is poor.

Interesting. I don't use WatchPower myself. I actually did find a Watchpower manual (the manual doesn't seem to have a version number, so it might be old), and it doesn't seem to mention any setting for output voltage (there is a field that displays output voltage, but I don't believe that any of those displayed variables can be edited).

It just adds to the mystery.

So, are you saying that your WatchPower doesn't offer you the ability to change output voltage?

Is the facility for changing output voltage missing from your screens?

Were you able to change the output voltage using WatchPower before the firmware update?

Did your machine come set up for 220 V output as delivered?

I can't see how the SCC firmware version would change the ability to set the output voltage.

Yikes! That is quite a high equalising voltage. I suggest that these batteries are not suitable for these inverter/chargers. Even if you had a separate charger to perform occasional equalisation charges, you'd have to disconnect the inverter when doing this. It would be quite a nuisance, I would imagine.

@lion6912, You do not need to equalise this battery at 2.7 V per cell. I believe that is a misreading of the manual. I found an English version of the manual here:
http://www.crownaku.com/Resim/Upload/td ... 0hdeng.pdf
I believe it is only saying, as a safety condition, you must stop charging if any cell reaches 2.7 V.

The type of charge profile described in the manual is a very strange one. It is described as being for electric vehicle use. The inverters discussed in this thread are not capable of doing that kind of charge profile. In fact very few chargers of any kind would be able to do it.

You need to obtain a description of a conventional 3-stage charge profile (Bulk, Absorb, Float *) for those cells. Failing that, a conventional charge profile for any flooded lead acid cell of similar capacity should do the job. The charge profile given in the manual in this post would probably be suitable:

I never can change output 230V on mine.

I have a pdf to watchpower if you want.
You can change outpower and equalization.

Thanks Weber.
I have buy my new battery cronw there is 2 weeks.
And I charge at 58V and floating at 54V. It's allright ?
Anf how do equalization ?
