Re: PIP-4048MS and PIP-5048MS inverters

I agree with Coulomb. 145 V is an absolute maximum limit for array open-circuit voltage. You need to know the coldest dawn panel temperature you can expect at midwinter in your location and use it to adjust the panel's datasheet Voc (which is at 25 °C) using the datasheet temperature coefficient of ...

@Lee I suggest anyone hoping for solutions to the various problems with Axpert Kings should also keep and eye on the South African Power Forum, in topics such as this.

Re: PIP-5048MK inverter

Welcome Lee . I'm sorry it has taken me so long to reply. Unfortunately, Coulomb and I cannot make any changes to the firmware beyond those offered above, as we do not have an MK/King for testing. This also makes it difficult to answer any questions about the inverter's behaviour and how this might ...

Re: PIP-4048MS and PIP-5048MS inverters

I'd state the conclusion a bit differently from Coulomb. I'd say the 64 V models are an abomination. They claim to work with nominally 48 V lead-acid batteries, and they claim to be pure sine wave. And yet they can't even produce a pure sine wave at 48 V, if they have any kind of load on them.

Re: PIP-4048MS and PIP-5048MS inverters

I have a new question however. The new guy is on firmware U1 74.31 Do I still flash PB1_72.70b to both the 5KW and 4KW in order to parallel them? The new inverter also shows U2 04.12. Can I leave that as is? My PV array only connect to this inverter. For some reason I get no PV readings on the othe...

Re: PIP-4048MS and PIP-5048MS inverters

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-...

Re: PIP-4048MS and PIP-5048MS inverters

@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.

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 ...

Re: PIP-5048GE, PIP-5048GK and PIP-5048MG inverters (with unsafe SCC)

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...

Re: PIP-5048MK inverter

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 ...

No. Unfortunately, the update does not create a backup of your existing firmware. The existing firmware is copy-...

Re: PIP-4048MS and PIP-5048MS inverters

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...
