can you share this file for us on 71.86 to upgrade?

Hi @Youda I am using this cable (see attached) I am not sure of the specific type of profile it uses. but I connected it to the ICC pi together with the crimped cable I ordered and BOOM it worked just like that Perhaps a quick google of the name TRENDNET TU-S9 as clearly written on it will reveal more on it Regards

Ok see the attached image. I remember purchasing this cable from aliexpress https://www.aliexpress.com/item/32888242837.html I instructed the seller to crimp the cable as per the attached file. he was kind enough to do so you can also get this usb to rs232 serial converter and you are good to go https://www.aliexpress.com/item/405959038.html?spm=a2g0s.imconversation.0.0.160a3e5fY7h4I8

You can make yours. I did same. the schematic diagram have been posted on this forum will look for it and place here if I have the chance

Hi @Cor Unfortunately I have since moved away from using the wifi box and settled with ICC software. I remember I had similar issues and had a marathon email sessions with MPP Taiwan. part of the pdf on how to configure the wifibox setting they sent to me is attached for your use. PS: Make sure you input correctly in the wifibox homepage setting your home internet SSID and password word for word Wifi box & card quick setting(EN).pdf

Hi @Cor you need to open up the WiFi box with a screw driver and change the jumper from “1-2” position to “2-3” position to manually reset the box to default as stated in the manual

just as @Coulomb said the rs-232 cable that came with the axpert inverter connects to the serial usb cable you will purchase (see pics below) I finally got to update both the Main firmware and screen firmware this morning. There was a little bit of scare though when I was updating the screen firmware. The inverter screen went blank completely and I panicked. I finally re-pluged the cable after I had removed it and shut down the batteries, started the flash all over again, when it completed 100%, the inverter screen came back on

Hi @Coulomb According to the axpert king manual, flashing of new firmware can also be done through a flash drive connected to the USB port. Just want to know if this is applicable in this scenario using these softwares before I upgrade my inverter Thanks

Hi can you upload the screen firmware 2.00 for download? i know @Coulomb only posted the main firmware 71.86 thanks

@ChristoSnake are the 24x330w Canadian solar panels connected to just one infinisolar 5Kva inverter in your setup? That thing has like a maximum PV size of about 4000w according to the spec sheets.

Well, if the 375W in 3S2P arrangement will not exceed the max 145voc recommended by the inverter and limits itself to the 330W ,then I don't mind this. just want to be sure there wouldn't be any other issue Yea I know shipping/export/import do suck sometimes and come with its headaches. my shipper misplaced my Pylontech cables from china and he wasn't really happy having to pay for the full purchase and shipping

my Pylontech batteries are currently communicating with the axpert king inverter and it uses a charge and float voltage of 53.2V which cannot be altered unless one disables the PLY 05 setting and go for the USER option. I hope this is not an issue going by your recommended 52.5V? for the Jump, I have noticed that my batteries usually ideals at 89% SOC for some hours before it gradually moves to 100% within 5 minutes or less

Hi @Jaco de Jongh Thanks for the reply. Unfortunately I am in Lagos Nigeria not SA Looking for a quick solution I can come up with locally that will not involve importation Thanks

Hi Guys I really need your advice right now @plonkster Currently have 6 numbers 330W Canadian solar Panels in 3S2P hooked up to an Axpert King (used to be a Morningstar Tristar MPPT 60A which I have retired) Looking forward to double it to meet up to the 4000W and 145V limit of the inverter. unfortunately, my local suppliers don't have the 330W in stock anymore. They only have 305W, 375W and 385W available.I am looking at adding 375W in 3S2P to the equation as a last resort. Is this advisable? 330W data is voc=45.6,vmp=37.2,isc=9.45,imp=8.88 while for 375W voc=47.6,vmp=39.8,isc=9.93,imp=9.43 What possible scenario / option do I have to take to not exceed the 145V max of the inverter and at the same time add up more panels. thanks

I remember reading up on this report and was shocked with the results of the Pylontech batteries Happy I went this route

Thanks for this Youda Will give the ebay link a go I'm not from SA and I don't think they ship international

Hi Youda my Shipping agent misplaced my Pylontech cables connecting the batteries to the inverter when I ordered for 3 numbers US3000 batteries. I have informed the factory for a replacement but it’s taken time Please where can I order for these cables online ? Thanks

Hi Coulomb I will be installing 3 numbers US3000 sometime next week. going by your analogy (3x 35) = 105A rounded down to 100A. Just wondering if charging the batteries with 100A is not on the high side?

This is the problem I am having...... I had already connected the wifi box with the cable supplied to the inverter and I used a spare DSTV adapter as power but I wasn't seeing any SSID as "wificard" among the listed wifi's on my windows 10 laptop. I have contacted MPP Taiwan and they said I should get a 12V 1A adapter as power. Hopefully I should get one today and keep you posted Thanks once again

Hi Coulomb Thanks for he help so far. you have been wonderful Just a final question, please. according to the manual which I have screen grabbed and attached below, how do I go about creating and connecting to an access point named "wificard.net"? Do I need a separate router for this? I know you were mentioning something like that in your previous post but I just couldn't wrap my head around it Not usually the brightest one in the room when it comes to techy things 😁 Thanks

Hi Coulomb Yes its the PIP-5048MK model AKA Axpert King I was sent the wifi box and this wifi card (which I have been starring at and wondering what am i suppose to do with it) see pictures I can connect the wifi box directly to the inverter with the supplied cable but there is no wifi acces point to connect to when I check for wifi on my system as described in the manuals The way I see it now seems the wifi card is meant to be powered on (unfortunately no cables supplied with it) and a LAN from my router connected to the port LAN on the wifi card Contacting MPP Taiwan already but their response time is abysmal

Hi I recently bought and MPP PIP 5058MK inverter and also the wifibox and a small wifi card See Pictures) unfortunately, the wifi card did not come with any cable for power and the manual that came with it did not mention anything about it How do I get this thing powered on? what cables do I need? Thanks

on a second thought, having a BMV 712 battery monitor connected to the Pylontech batteries should be able to also give an accurate SOC? I already have the BVM, will be going this route.

This is interesting. Will be following this topic judiciously. Expecting my Pylontech batteries October ending. I have always liked the simplistic nature of the Venus CCGX interface on a pi. It just gives you a quick glance to all the important datas thanks for this
