Re: PIP-5048GE, PIP-5048GK and PIP-5048MG inverters (with unsafe SCC)
is their any firmware to change the voltages pip-5048mg uses grid power for ?
for some reason when grid is connected it always uses grid if power is under 1000w and over 3000w
also all through out the night is switches between grid and battery
anyway to stop it always using the grid under low loads ? also idea's why it never wants to charge over 4amps ?
we have 4.5kw worth of panels attached 8s3p 190w panels
unit runs fine without battery / grid connected (accept when a cloud passes over and you have to turn it off then back on again .. )

Re: PIP-5048GE, PIP-5048GK and PIP-5048MG inverters (with unsafe SCC)
What battery do you have? How old is it?
Do you have loads with a heavy in-rush current?
Your battery voltage dips below 50 V, sometimes below 48 V, suggesting either high peak loads or a battery with high internal resistance.

Re: PIP-5048GE, PIP-5048GK and PIP-5048MG inverters (with unsafe SCC)
Hi
In my lab i receive many inverters (Axpert vmiii 3kw having maximum VOC 500volt) with fault 09 (bus soft start fail) i saw the problem was in MPPT side of inverter, the components which were faulty are as follow
1). 3845 8pin dip ic
2). BG30 dip mosfet
3). 8120 dip diode
4). 41-0705521-01G. transformer
5). 01b 1k resistor
Now i dont know what is the purpose of the components can any body explain the circuit diagram of axpert vmiii model? Why these components blown away again and again.

Re: PIP-5048GE, PIP-5048GK and PIP-5048MG inverters (with unsafe SCC)
The 3845 is almost certainly the power supply for the drivers. There are several 3845 ICs in power supplies in the various models.Roman khan wrote: ↑Thu, 03 Sep 2020, 19:22 what is the purpose of the components can any body explain the circuit diagram of axpert vmiii model?
The MOSFET and transformer could be power supply or Solar Charge Controller (boost converter). The transformer could be isolation for a gate driver.
The diode and resistor could be anything.
The power supply is likely driven from the PV input, which has a wide range of voltage operation (120 to 400 or 500 VDC). Also, bad things can happen when the PV has leakage to ground; there is no insulation monitoring with these higher voltage solar charge controllers. Maybe the power supply and/or MOSFET drivers are the first casualties if there is a flashover to earth or significant leakage during rain. I'm sure that most users ignore the warning about the insulation class for panels to connect to these models.
Finally, I believe that the digital PWM signals come from off-board, via a cable. It's possible that switching spikes from elsewhere or even the boost controller itself get induced into the cable. [ Edit: or is this the corner of the main board? ]

Re: PIP-5048GE, PIP-5048GK and PIP-5048MG inverters (with unsafe SCC)
Is that the 1 kΩ resistor that connects to the 3845 pin 3? If so, it's a current limiting resistor (not doing its job by the looks) connecting the source resistor to the current sense input of the IC. Does the source resistor (I assume it's the large through-hole resistor near the 3845) take a belting? Maybe the MOSFET (which I now believe is part of the power supply) fails first, putting a large sharp current through the source resistor, the inductance of that resistor allows a spike of voltage to feed into the IC via that tiny resistor. The spike kills the resistor and the chip. That kills the power supply, preventing further damage.Roman khan wrote: ↑Thu, 03 Sep 2020, 19:22 ... the components which were faulty are as follow

Re: PIP-5048GE, PIP-5048GK and PIP-5048MG inverters (with unsafe SCC)
I mentioned the PV leakage issue here. It's even possible that this is how the problem manifests itself in a PIP-GK / Axpert VM III; the post refers to PIP-MG / Axpert MKS II models.

In this post, the user shows 41.14, and in this post, the user also shows 41.14. These may not be the latest ever, but that's all I'm aware of. The latter shows a removable display version of 02.40, which is recent but not the latest known (which as of now is 02.49).
Edit: I've never seen a 41.xx firmware update file.

Thank you coulomb.
The most recent I have is 41.07 and bluetooth 0.21
At least that one fixes the fan never shutting off issue. Contact me if you need it or want to play around with it.
Does anybody on here have a more recent version?

I am still hoping for an updated firmware to address the float bug for lithium, interestingly the current firmware now supports WECO in addition to the plyontech lithium batteries and I just wonder why MPP cannot just allow for a generic lithium charging profile.coulomb wrote: ↑Sat, 05 Sep 2020, 08:44In this post, the user shows 41.14, and in this post, the user also shows 41.14.

Re: PIP-5048GE, PIP-5048GK and PIP-5048MG inverters (with unsafe SCC)
Hi Ojeysky and Coulomb,
Does any one knows where is the firmware update for 5048GK ?
I been using ir for 18months and is a pain when fans goes high speed. It never goes back to normal without shutting down.
My seller says he don't have any update and stop repling me.
my current fw is:
MainCPU: 20.58
Remote Panel CPU: 2.00
BLE CPU 0.21
Thanks in advance, I really appreciate your help

Re: PIP-5048GE, PIP-5048GK and PIP-5048MG inverters (with unsafe SCC)
The 41.07 mentioned is a GK firmware. However, with the major version number so different, I'd be reluctant to update to that version.
Main Axpert VM III 5K-48 (PIP-5048GK) firmware version 20.59 is here. [ Edit: it says 1.0.0.0, but that's the default that people often forget to change. I'm certain it's 20.59. ] It was uploaded in July 2018, but should work with your hardware. There is a small chance that the fan speed issue is fixed in that version.my current fw is:

Re: PIP-5048GE, PIP-5048GK and PIP-5048MG inverters (with unsafe SCC)
My little solar grid conist of the following components:
6x 300W solar modules
1x Inverter Isolar (easunpower) SML II 3,2Kw aka PIP 3024GE.
2x Lead acid CA/CA 12V 180Ah batteries
Due to the calcium dotted lead in the batteries i have to charge them with a higher voltage as pb/pb batteries. I think around 16V (2x16V=32V on the inverter)
I can't charge them full.
I set the bulk charge voltage in the menu to max at 31,5V float to 27,2 and also tried above 30V
the inverter charges till it reaches 30V and there it remains with constant 4A charging current and does not go further up.
When i try to equalize with 31.5V it also just reaches the 30V.
Charging current is set to 60A and 30 from util.
My batteries are just 4 weeks old but dont give me enought energy.
150w drain from 6pm .... at 00am i have to recharge by util because voltage has dropped to 23,5 ...charging by util drains 30A til it reaches 28,6V and then drops to 4A by mantaining 28,6V till the morning.
Does somebody knows how to release that brake in charging voltage?

Re: PIP-5048GE, PIP-5048GK and PIP-5048MG inverters (with unsafe SCC)
What would be an optimal inverter temp reading, I have two inverters in a single enclosure the temp that one of the inverters is reporting to ICC was 63C with the cabinet door closed (ambient is like 22C), I open the door it drops to 53C within 30 mins or so, inside the cabinet was hot when I opened it, there are two fans in the cabinet but they don't seem to be helping a whole lot, about 55A solar going into the inverters, less than 1KW of house load.
The reason I ask is I just had a power outage in the house while on battery power, just a few seconds and so I'm wondering if an inverter rebooted because of heat.
Thanks!

Under 50°C. Though with fans blowing down as they come from the factory, you have to say under 60°C. See this post.
You certainly could do with improving cooling in your inverters. Fan rectification is the easiest quick fix; see the index of the PIP-5048MS etc topic. But I would also attempt to improve air circulation in your enclosure.

Re: PIP-5048GE, PIP-5048GK and PIP-5048MG inverters (with unsafe SCC)
Does anyone have a tool to read the logs that the inverter produces?
My installer came over Saturday and grabbed the logs and is sending them to MPP, he mentioned you need a tool to read them.
Since my power outage on Wednesday, there were a couple of other random outages (while on bypass), Friday morning and Saturday morning, they're 1 second outages enough to power cycle everything and disconnect the NBN (my FttC NBN needs me to pamper it before it will reconnect which is really annoying) oh and the Saturday disconnection was the last straw for my Unifi WAP, after nearly 5 years it gave up the ghost.
On Thursday night I noticed the batteries were draining way too fast, I went out to check them and some of the batteries had tripped (I assume during the initial Wednesday event), I tried to turn them on and I had a 1 second outage, long story short, two batteries were at 46v and six were at 53v. It was dark and I was over it, I isolated the batteries from the inverter and left them like that, so the inverters were in bypass mode.
When the installer was here Saturday he managed to take the power out trying to introduce the batteries, there are no apparent issues with the inverters. We did get the batteries balanced and everything is OK right now, weather is crap so the system should switch to grid in a few hours.
What is with these inverters, surely I should never get a 1 second outage, paralleled?
Anyway probably going to get a Latronics ACTS40 to bring some of the "boring old" grid reliability back.

Re: PIP-5048GE, PIP-5048GK and PIP-5048MG inverters (with unsafe SCC)
Probably unrelated, but I have seen a 1 second outage on my old pip 4048HS unit, not sure how many times it did it before I saw it happen.
The inverter was only running a big fish tank with all accessories, so should not be using more than 150w.
Turns out the little pump had worn out inside and shorted out till eventually it burned through the wiring inside the pump.
Anyway the inverter has been running perfectly since.
Others may have different circumstances.
Everyone has different configurations and maybe completely different problems.

Thanks Revlac, the system runs the whole house, it's been stable since it was installed 4 months ago.
I hope it's not a problem like you had, who knows how I would figure out the culprit.

Re: PIP-5048GE, PIP-5048GK and PIP-5048MG inverters (with unsafe SCC)
I'm not aware of any real "logs"; when "fault recording" is enabled, the inverter stores a snapshot of values that led to the last fault in EEPROM (only one fault's data is stored). This data can be accessed with the undocumented QFS and QFAULT commands, which I document here (accessible from the index of the PIP-5048MS topic). I'm not aware of any tool that can spit this data out, but it would be easy enough to write.
There is also a "snatch graph" stored in RAM, where some internal data can be snatched (snapshotted) in real time, but I think you have to trigger it with a special command, so it's no good for historic information.
