Hi
I am new with forums, etc.
I need some help regarding firmware for 5kva Axpert in parallel.

Please guide me where to go for help.

If possible could you give me some advice what firmware to use.

First Just a explanation of my setup.
I have
2 x 5kwa mecer inverters in parallel
24 x 250W solar panels (12 on each inverter.)
12 x 220Ah Silver Calcium batteries
The parallel system is working but when I connect the generator the firmware seems to me do not understand whats going on.
I upgrade yesterday the firmware U1 to 72.70b and U2 to 4.10 on both inverters.
Today it seems the fans running a bit high.
I did not test the generator today.
Do I use the correct firmware update?

firmware for 5kva Axpert
There are at least three models that fit this description: the PF0.8 (which I assume you have), the PF1.0, and the Axpert II 5kVA with 450 V MPPT. There will soon if not already be Kings, at least 2 Value Line models, and no doubt more. So please be more specific than "5 kVA Axpert".
The parallel system is working but when I connect the generator the firmware seems to me do not understand whats going on.
Axpert / PIPs are very fussy about generator frequency, voltage, and probably wave quality. You may have to use the APL instead of UPS voltage range (setting 03). Also, if the generator is your only source of AC input, you'll want to be using Uti output source priority (Setting 01), so that the generator is used as soon as it is detected. Check for the little "tennis ball" (sine wave in a circle) icon near the middle left of the LC screen. If that icon doesn't appear within a second of the generator starting, or it flashes, then it doesn't like the generator and won't use it.

I upgrade yesterday the firmware U1 to 72.70b and U2 to 4.10 on both inverters.
Today it seems the fans running a bit high.
If you started with older firmware, then the fan behaviour could well have changed. If you update to 73.00e, you will observe even more fan activity.
Do I use the correct firmware update?
If it's working at all, then you likely have used the correct series of updates (the 72.XX with XX ≥ 40 or 73.00). But there is no need to stop at 72.00b; it is obsoleted by 72.70c. There is also no reason not to progress to 73.00e.

Did you not find the post Can I update my firmware, and if so, to what?

If you did, please tell me how I can improve the instructions so that you would be lead to the most recent version in that series, which is 73.00e. 72.70b is over 2 years old.

That MK series is new one if we speak MPP Solar PIP series.
Yes, sorry, when you said "trio" I short circuited to the triple-MPPT models. Sigh.
MPP Solar says that MK is this year new product (and that why I think if those is maybe ones of the first units =) ).
It seems to have taken a few months for MPP Solar to decide to carry the Axpert King (as a PIP-5048MK). So while yours may well be one of the first labelled as PIP-5048MK, I believe that the Axpert Kings have been available (under other labels) for perhaps six months.
what can use (16V @ 12V) to equalization.
The most common battery that needs this really high equalisation voltage seems to be the Trojan (flooded lead acid). These are well respected batteries, if you want lead acid and don't mind the maintenance, so it's good that they are finally supported.

Hi guys,
I've read most of this thread, it's very informative. My new house is about to be build, i'm living in Europe (France) and i'm going Off Grid, and the PIP 5048 seems to be a nice solution for me.
I'm planning on heating my water for showers but also to heat my house with PV. I've discussed a lot with electrodacus but his DMPPT is not for me.. too many drawback.

Plan is :
- 7kW of PVs
- One PIP 5048
- One PCM60X
- 5kWh of LiFePo4 (then 10kWh if needed)
- A system to heat my water

The question is more about the water heating done with a PIP 5048, the way i imagine it is to "dump" (do not know if it's the proper word) the excess energy to the heater. For that i imagined a priority list :
1 - DC Loads : < 200W (a dedicated 48V DC circuit in house, phone charger, water pumps for aquariums, lights, Arduino ?, Various Electronics)
2 - Inverter 220V Loads : < 5kW (appliances, tools.. )
3 - Battery Charging : 0.25C : 1500W
4 - Heating Water : all remaining power (One tank for shower and one to heat the house)

Did someone build this kind of thing and how did you connect the resistive element of the heater ...on the charger side (DC) or on the inverter side (AC) and how do you control the amount of power to use 100% available PV power without takin too much ... clamps on pv electric lines ? A dedicated pv to sense the irradiation and deduce the available power ?

Thanks .. ;D

I don't think that this will end up being practical. 48 VDC is difficult to switch and fuse, and most appliances (such as a phone charger) will come with a 220 VAC plug anyway. Why not use the already existing sockets for these? Yes, it's a little more inefficient to convert from 220 VAC than 48 VDC, but I think you'll find the difference is negligible.

A lot of us wonder about ways to "soak up" wasted solar production, myself included. I'm still keeping an eye out, but I suspect there isn't much that can be done. However, with 7 kW of solar panels, you would have more incentive than most to find a use for the excess energy. The trouble with water and home heating is that you need more of it during the time of year that you have least solar production: in winter.

In summer, using excess energy to freeze water might be a good use of the energy, particularly if you can operate a chilled water circuit in the house in place of an aircon.
250 kg of frozen water would be a pretty neat way to store 'cold'.

For heating water there are 48v elements available to replace the ones in hot water tanks
a dual element tank would be ideal one for the grid (top one) the other dc solar (bottom one)

Here is a view of the wireless meter now operating on my system and its 40 meters
through various walls Note I fitted the high power radio modules nrf24L01 with rf amp and low noise amp
No mater how I take a picture with my tablet it always comes out upside down on the forum!
Also I had not set the correct Ah capacity in the meter so the SOC is not correct in the picture

Perhaps it was an Apple tablet; this seems to be a common problem. Apple and the rest of the world don't seem to be able to agree on one technical detail about the JPEG file format.

I took the liberty of rotating it 180° in Windows Paint, and resizing it to 50%. About 2 minutes work (in Paint).

Good day,
I've got an Axpert MKS II 5kva 48Volt with 80A MPPT (4kw), which seems to match the PIP-5048MS.
I've got 12 320W panels attached in 4 x 3 strings with a SolarMD 7.4kwh LiFePO4 battery bank with its own BMS.
The inverter has firmware version 74.30 loaded on it.

I've noticed the presence of the floating voltage charge bug: Round about 8:00 in the morning the inverter reports about 1KW
input from the solar panels. If I open the circuit breakers of the PV lines, wait for the inverter to register the removal
of PV and closes them again the inverter reports about 2kw input from the solar panels.

The maximum charge current is set to 60A.

Is there a work around for this problem, since it looks like there isn't factory firmware available for this unit to be patched?
Will the v74 firmware (for the 64V battery option model) 'brick' the inverter?

Regards,
Frikkie

Good day,
Welcome. I had to move your post, since you stated that it's an MKS II which is a high voltage MPPT model. [ Edit: but it can't be an MKS II after all, so it's moved back here where it started. ]
I've got an Axpert MKS II 5kva 48Volt with 80A MPPT (4kw), which seems to match the PIP-5048MS.
No, an Axpert MKS II matches the PIP-5048MG. [ Edit: however, it seems that you have the equivalent of a PIP-5048MS. ]
I've got 12 320W panels attached in 4 x 3 strings with a SolarMD 7.4kwh LiFePO4 battery bank with its own BMS.
The inverter has firmware version 74.30 loaded on it.
? Well, that seems to be a 145 V MPPT firmware, and if you are connecting it with 3S panels, you're apparently trying to keep the PV voltage under 145 V.

Can you post a photo of the larger sticker with the bar-code and specifications on the side of your machine, please? It could be that our information about model names is wrong, and it would be good to get that corrected.

It would be more convincing if you are able to confirm that the battery voltage with about 1 kW of charge was keeping to around your float voltage, and that after the "PV reset" at 2 kW charge, it soon exceeded that voltage.
The maximum charge current is set to 60A.
Presuming that the firmware is similar to others, that would mean that your current threshold is about (60 A / 5) - 1 = 11 A on the battery side, or a bit under 600 W. f you notice your charge current not returning after a < 600 W cloud, then you have the premature float bug.
Is there a work around for this problem, since it looks like there isn't factory firmware available for this unit to be patched?
No, sorry.
Will the v74 firmware (for the 64V battery option model) 'brick' the inverter?
? You say you already have 74.30 firmware.
But most likely, using any available patched firmware, if you force it in there, it won't work as expected, and will most likely cause even more problems. You then won't be able to "roll back" to 74.30.

Sorry to have to tell you that. However, you may be able to help others with the photo of your sticker, as mentioned above.

Welcome @suorama @apam and @Robbe01. Thanks for your input. I've started a new topic for the PIP-5048MK (Axpert King 5K) and moved your posts there, so they don't get lost in this huge topic. I'm sure we'll be hearing a lot more about the PIP-MK in future.

Thanks Coulomb,
Why a dedicated DC circuit... mmm perhaps i'm wrong but i feel that shutting the inverter off during the night is better, my aquarium pumps and heaters need to run 24h24, that's roughly 60W pump and 300W heater (heater will only be used to keep water over 18°C during the night, security cause it should never happend, an other one working on AC will get the temperature to 23°C the day).
The thing is that batteries are expensives and inverter at low load got pretty bad efficiency, like on a 5kW inverter if i draw 60W then it will end use something like 100W.
Image

Dc to DC converters are dirt cheap, adding a 48V to 5V converter to charge my phone seems efficient and cheap.

But point taken on the difficulty to switch and fuse, still this 48V circuit will be a "low cunsumption" circuit, not more then 15 amps, it would mainly be for ghost night consumptions.

I run a 24 port 10/100 switch , my VOIP ATA , wifi access point , security light and a micro-controller tcpip remote control off 48v via dc/dc converters the total drain is less than 2 amps Note the access point has POE so it is powered by its own converter.
Switching and fusing 48v is not difficult some of the mains circuit breakers are rated for 48v DC use , switching by relay works fine and using a spark quench circuit around the contacts saves them from wearing

Presumably, that should read PIP-5048MS (64V).

The correct version for you is the LFP flavour of patched firmware version 72.20e, i.e. the file to download is dsp_LF1_72.20e pf1 64V.zip .

All patched firmwares with the exception of version 75.31a are available in both LFP and non-LFP (LC) flavours. I've tried to make that clearer in the topic index (first post) now. You just pick the file with LF1 in the name if you want the LFP version, and the one with LC1 in the name otherwise.

Hi,

I have successfully updated an Axpert MKS 5KVA Pf1 variant with some input from Coulomb.

The inverter is branded Voltex, a South African Electrical distributor.

Model Name: VOLTEX MKS 5KVA
Colour: Silver and Black
Rated Power: 5000VA/5000W
It seems to have the 64V option installed as I could set the voltage to 64V
It has the 145VDC MPPT SCC.
It was running FW 72.20 and I updated it to 72.20e.

Thanks for pointing that out. I have just uploaded a new version of the AussieView manual to correct that oversight, with the following:

SAv [04] nor    Power saving mode  Normal (AC on, DC-DC on, 50 W no load)
         SdS                       Saving disabled (AC on, DC-DC 33% when low load, 46 W no load)
         SEn    (when PAr = SnG)   Saving enabled (AC off when low load, 2 W no load)

"nor" is present in the unpatched (i.e. manufacturer's) 73.00 firmware, but is not mentioned in the manufacturer's manual. The above information is based on painstaking investigation by Coulomb. Neither Coulomb nor I can see any point in having the "nor" option, except that maybe turning on a very heavy load might make the AC voltage sag less, and hence lights flicker less. We haven't tested this.


it has very important point , when running in off-grid , if during winter time you have low solar power , the internal power consumption is higher than charging rate , in my case seems that 50W is too low for stopping the inverter to avoid discharging the batteries , it destroyed my batteries by discharing them , this setting should be set to a minimum 100W to overcome the internal consumption of the inverter , i need help doing that , i`ve search all over the net , i`ve tried all 3 options of parameter 4 , and now , i`ve written an email to support@mppsolar.com , i hove someone will reply.

I don't have a battery yet and 27.3v from my psu is no good to power the beast so i used my 20y old nicd from my car.
Updated to 72.20e thank you guys for all the wonderful work you did.
