I don't think that you need to settle for this. I also have a 2015 Axpert and recently (successfully) upgraded the firmware to Coulomb's one (LFP flavor). Am now running the Axpert with Pylons and PV without any problems - together with ICC

It needs a serial port to connect to PC. Cable came with inverter but to find a pc that still has a serial port that has not been converted to a media port is not easy.

I bought a USB to serial converter from Communica (something like this), which worked perfectly together with the original serial cable and ran the firmware update from my laptop

@Johan Smit You mentioned that you want the inverter to bypass on heavy loads.

Might want to enable setting 23

? You just use a USB to serial adapter. Unless I'm missing something here.

Hi there. 

I stumbled over this thread while trying to get a Pylon US2000 to talk to a axpert 5k, same as Johan Smit. I'm using it mainly as a UPS for running PC and router during outage. 

i used the link for the 73.00e firmware update and the folder had dsp_LF1_73.00e.hex file in it, but running the update software only lets me use the dsp.hex file. i think i almost bricked the inverter trying to use the LF1 file. i dont see a LFP option in the battery profile, is there some sort of magic sauce needed to get it to work?

thanks in advance

That's how the reflash tool is written, it looks for the fixed name dsp.hex. We provide the zip file with the same contents in dsp.hex as in dsp_LF1_73.00e.hex. You might notice that the two files have the same size.

You select Battery Type (setting 05) as USR, then provide suitable values in settings 02, 26, 27, 29, 12, and 13. I'm away from keyboard at the moment, but there are several posts with the magic numbers for PylonTechs.

@Coulomb Thank you Sir. just hooked up the US2000 with 73.00e firmware. there was a bit of a wobble at the end of the update.( was rather slow at 8 blocks/s) when i tried to switch off, and on, it didn't want to and it became unresponsive. So i tried to update firmware again, which it did, meaning the MCU was still kicking ( there was some swearing involved for motivation).

after some digging on the forum i decided to try these settings for my setup, similar to Mr Johan Smit

out	1	utl
tot	2	10A
InP	3	UPS
SAu	4	SdS
bAt	5	uSr
oLr	6	Lrd
otr	7	trE
out	9	50hz
utL	11	10A
b2u	12	46V
u2b	13	51V
ChG	16	utl
bEP	18	bon
LCd	19	HEP
Llt	20	Lon
ALM	22	Aon
oLb	23	bYE
rEC	25	FEn
AbS	26	51.8V
FLo	27	50.4V
PAr	28	SnG
Cut	29	47.5V
SoL	30	onE
bAL	31	Sbd
AbS	32	Aut
nEC	38	dlS

 

I do not have solar on my system (for shame, i have 6m^2 of roof space facing north and rest of the house is faving east west at a horrid A frame angle.) so thats why I went with the guess on the settings above.

I will be getting a copy of ICC and try get the pylon cable to interface with ICC (if there is ever stock again).

thanks again.

 It sounds like your comms board is marginal. Lots of retrying, and too many retries near the end, so it failed. Good on you for persisting.

Please pardon the formatting below, your table of settings has weird invisible characters in it.

Quote   tot 2 10A       utL 11 10A Those could go up to 20 A, to charge the battery twice as fast, yet under the 25 A maximum.
Quote   b2u  12 46V u2b  13 51V   Those are very low. But if you want to run the battery as long as possible in a load shedding situation, and won't be in battery mode unless load shedding, I guess that's OK unless or until you add solar panels.

Good day Johan. You don't perhaps have the name of the company in Jhb who can do the update on the RCT 5KVA, for use of lithium battery.

Thank you.

Cobus

Hi just a quick question please is the RCT 8kw hybrid inverter compatible with Pylontech 5.1kwh lithium-ion batteries.
