Hi Mantas . If you want to have any chance of paralleling the new machine with the old ones, you must not buy a 64 V machine. That means you must not buy a PIP-5048MS. You need an Axpert MKS 5K that does not have the 64 V option, or a rebadged equivalent such as the Mecer SOL-I-AX-5P (not the SOL-I-...

@Mantas I just realised you have another (and better) option, that doesn't require you to reflash the new clone. You can reflash the old inverter(s) with the same firmware that is in the clone, which I assume is LC1_72.70c.

Hi Mantas . Welcome to the forum. Thanks for giving all the needed detail up front, to enable us to help you. The replacement you have been supplied with, is not a rebranded Voltronic Power Axpert MKS 5K but a pirate copy or "clone". See Coulombs post: Do I Own a Clone? (Oh, moan!) . And I'm guessin...

Thanks for this weber. Do you mean with the remark above other LFP's not being Pylontech, like 16s ones? Yes. The LFP flavour of patched firmware would be for LFPs other than Pylontech, whether 15S or 16S. It would also be for Pylontech if the inverter was made in 2018 and so could not communicate ...

So despite the considerable gap from 71.40 to 71.71, it looks like it should work. I presume your model, being a PIP, has the 64 V option? (In other words, can setting 26 go past 58.4 V?) Yes, and I don't know of 5048 MG versions which don't do 64V, as they are quite recent, do you? When a model ha...

Page 23 of the manual , implies that it is possible to update the firmware by plugging a USB flash drive containing the upgrade, in the correct format, into the USB port on the removable display, and pressing the correct sequence of buttons. If someone knows how to do that, please post a description...

Hi Weber thanks for the software Will this version be ok for Pylontech batteries LiFeP04 which usually come in 15S? Hi dekin. Thanks for the question. Yes, that will be fine, provided the inverter (PIP-5048MK or Axpert King 5K) is dated 2019 (or later) and you have set it up to communicate with the...

Beta Version of Patched Firmware 71.80d for PIP-5048MK/Axpert King 5K This patched firmware is our first one based on factory firmware version 71.80 for the PIP-5048MK and Axpert King 5K. Many thanks to affer for bravely testing this version, as neither Coulomb nor I have this model. This patched f...

Another consideration for you re MS vs MK vs GK is that they all come with the premature-float bugs . We have patched MS and MK (soon to be released) but not the GK, to fix those bugs. In that case my best option will be the MK and then use your to be released patch! Just to be absolutely clear: I ...

Is it possible to change the AC voltage from the default of 230v to 240v. Some posts on here seem to suggest it is by using POPV2400 command Yes, that's correct. but when I tried this it did nothing? Did you at least get a "(NAKss" in response? If not, how are you communicating with the inverter? W...

Once you have updated the firmware in your PIP, is it possible to revert back to the original (does the update create a backup of your existing firmware first) or is this a one way trip? No. Unfortunately, the update does not create a backup of your existing firmware. The existing firmware is copy-...

You say you wouldn't recommend the GK. In the same way you wouldn't recommend the MG? That's correct. I've got my MG wired with a spd on the panel side and a RCCB type B on the AC side and that seems fine. What do you think? I think many people would be very grateful, if you (or your electrician if...

I am about to create a system for a friend with some pylontech batteries and was looking at the MK and GK forums. Considering what I read here, would you all advise me to get a MS with a patched firmware instead of a MK? Besides that: trying to max out the # panels, would the MK or MS take 6p4s pan...

I think the biggest hassle would be that the firmware will treat the battery as "weak" (with several implications, including a low battery warning and switching to bypass mode if possible) when the battery voltage drops to below 42.0 V (2.0 V above the low DC cutoff voltage, setting 29). It won't b...

I work for a company in the field of Li-Ion battery technology. We have tons of Li-Ion-Batteries (NMC and NCA, so 3,7V per cell). we have VW E-Golf Batteries, VW Passat GTE, VW E-Up, BMW i3 and all other manufacturer batteries. A very typical batterie nominal voltage is 44,4V. Upper limit 50,2V, Lo...

So does the LC flavour [of the patched firmware] give a more realistic battery % indicator for Lithium Ion batteries on the front display? Marginally, in that the wild guess is a load compensated wild guess. The guessed SOC in percent is still basically the number of tenths of a volt above the DC l...

Yes, that's good news. It has been three years since Mazda's Dinosaur Declaration.

I have moved all posts about PIP repairs and hardware modifications, to the topic that was called
"PIP Inverter Error "error 09" bus soft start failed", which has now been renamed PIP inverter repairs and hardware modifications.

Hmm. I just learned 3 good reasons why the next larger multiplier should not begin with X. 1. When you pronounce it, it will sound like it should be spelled with a Z, and so it can be confused with Z for zetta. 2. When you write a symbol X, some people will assume it is the symbol for "exa". 3. A sy...

I'm a complete nerd so I love this post. Especially Claude Litre :D You learn something new every day! Here's one for us nerds, that I just learned today. You know those prefixes for really humongous quantities, like tera, peta, exa, zetta, yotta, that are increasingly seen attached to "joules" or ...

Question to all have apparently the resistor R250 defective can give me one of the value of the resistor R250 in ohms. (Board is 48V)

R250 is 30 kilohms.

Q1 should I replace capacitors and MOS-fets or ditch my plan to make a 16S pack and make a 15S4P or even 14S6P even though that will make it more difficult to use the existing hardware. I recommend you use 14S if at all possible. Replacing the capacitors and MOSFETs is a terrible job, and even the ...

The regen braking is good, but it's almost worth adding a switch which doesn't activate the brake lights. 5 or 6 kW isn't much braking power. It certainly feels like an auto in that will 'run on' once you are up to speed. So it will take some care and slight change in driving style. Is there any po...
