Hi, does anyone got ICM working with RS485 at all? I would love to know because if the problem it's simply that my usb adapter doesn't work and I need another one, and in case you do have it working please tell me which usb to rs485 adapter you have, thanks

Hi, I've just bought a Deye 8K hybrid inverter and I'm pretty happy with it and it feels like a massive update from the Axpert 5.5K hybrid (bought 2, both broke, first one in less than 2 years and second one in less that 1 year) and since I was using ICC for those axpert I bought ICM since it's basically the same thing I used but compatible with Sunsynk/deye The problem is that I bought a RS485 to usb thingy (https://www.amazon.com/-/es/JT0069/dp/B07B93HX2H) and I broke 2 different rj 45 cables to conect them to the rs485 to usb but ICM (it does recognize that something is plugged in the usb this adapter is plugged in) just won't read any data from the inverter through this adapter, idk if it's the adapter itself, the pinout being wrong or what ICM doesn't tell me an error or nothing, ICM does read data through the RS232 port but I would like to keep the RS 232 port for the solarman wifi and because this rs 232 I have is normally used to read the pylotech us3000C and B batteries through the pylontech console port I have seen this premade cable but it's like 73€ to send it to my country which is quite a lot https://solar-assistant.io/shop/products/sunsynk_rs485 The pinout I followed was from the inverter's manual, so pin 6, 7 and 8 I also tried 1, 2 and 3 with no luck:

Hi, you need to update the batteries' bms firmware with a windows computer, specially the us2000 that are older, I know because I have ICC and also had that issue and updating them fixed it, this is the program and upgrades that pylontech provided me, I recomend you ask them since they will provide the lastest version and you should get a upgrade file specific for the us2000 since my batteries are us3000: Cheers

The first one of the links literally links to the VariCore batteries I bought, he's saying they are the best price, I'm glad they agree and that they say they are high quality On the page it says that the terminals are weak and the thread breaks easily which is true, I almost broke one of the terminals by tightening it too much, luckily I didn't break the whole thread and managed to screw it decently so do be careful about that, they must use some kind of weak soft metal on the terminals so don't tight it up too much, a bit is enough They actually reduced the price almost 10% from when I bought them

By searching "280a lifepo4" or "280ah lifepo4" something like that on AliExpress search So far my portable battery pack has been working perfectly but I really don't use it all the time, maybe 1 to 4 times a month I don't see why not order batteries from there, of course there's always the risk of shipping but mine came very well packed every cell was separated from each other and echa one had a 5cm wall of protective soft shipping material around them and AliExpress has buyer protection too, you can even get a partial refund if the thing you ordered came with a visual part broken while still working perfectly apart from the visual aspect of it for example Cheers

Pylontech did tell me that they don't recommend updating if there aren't any issues with the battery, they didn't gave a reason why though

Yup, mine also does this, at 89%SOC stuck temporally until it jumps to 100% after the update aswell

I've seen my Us3000C do that exact same thing, not sure if the update fixed the issue for me, it might have actually Cheers

Yes, for some reason pylontech themselves say to use the US3000A update for US3000B batteries, they probably have the same BMS or something, the difference between an A battery and a B battery it's probably very minor, I don't think I have ever even seen an A battery They specifically told me about this update Cheers

You need a RS232 to USB converter, the converters nomally have a male conector, so the cables you need to do will need a Female DB9 conector (that's how the conector is called, RS232 is the protocol), heres one: https://www.amazon.com/HL-340-Serial-Adapter-Support-Windows7/dp/B08QJNJP6P/ref=sr_1_55?dchild=1&keywords=rs232+to+usb&qid=1622562550&sr=8-55 you only need 1 USB to RS232 converter (you can just change it when using the Bs or the Cs) but pylontech US3000B uses a diferent console port conector from US3000C so you actually need to make 2 different cables for each version US3000B uses RJ11 on the console port, which is the same used by telephone lines (you might have one lying arround) US3000C uses RJ45 on the console port, which is the same as the LAN cables used for cabled internet on PCs for example (you might also have one lying arround) So you will need to get that RS232 to USB converter, 2 DB9 female conectors, 1 RJ11 cable with all 4 cables (some don't come with all 4 cables), and 1 RJ45 cable (with all cables as well) I would get a multimeter on continuity test to test which cable is which mix the cables as showed above and tape up every cable with electrical tape I'm pretty sure you can buy the US3000B cable somewhere but they are very overpriced I haven't seen the US3000C cable premade though Yes the updates up there will work as long as you use the US3000B update for the US3000B and the US3000C update for the US3000C Cheers

On aliexpress for 435.84€ or R 7324,76 https://es.aliexpress.com/item/1005001563505796.html?spm=a2g0s.9042311.0.0.274263c0sbFRZM, the bms for 123.92€ or R 2082,61 (250a 4S1P one) https://es.aliexpress.com/item/1005001349754494.html?spm=a2g0s.9042311.0.0.274263c0sbFRZM it also has a active battery balancer bms (15,38€ or R 258,48) which means instead of wasting the excess power of the cells higher voltage cells on resistances it instead charges the lower voltage cells with it so there's less power loss: https://es.aliexpress.com/item/4001171649360.html?spm=a2g0s.9042311.0.0.274263c0sbFRZM and the 12V 2500w 5000w peak inverter for 167,60€ or R 2816,7 but this was bought back in 2019 and this is a slightly updated version with a screen it seems, and also a bit more expensive https://es.aliexpress.com/item/33003269741.html?spm=a2g0s.9042311.0.0.274263c0gQ0tjK The inverter was bought next with a 12v 120ah lithium battery (1.44kw/h) for 275,40€ or R 4628,39 (back in 2019) that could output up to 950w I think, the thing is that this battery wasn't powerful enough for what I needed (I needed to power up a up to 1800w air compressor) Similar to this one but smaller 120ah version: To make that compressor work I basically had to put in paralel this lithium 950w battery and a big tractor start up battery, this worked until the lead battery got discarged and then it would put more pressure into the lithium battery, voltage dropped to like 9V or a bit less when trying to power up the compressor, the buses on the lithium battery heated up so much that the plastic arround them melted (kind of acted as a fuse) and stopped the metal arround them from being well connected, and also some inner cables that were soldered to the bms from the heat caused melted and got deattached from the bms and I had to solder them until I put some tape holding the cable in that position so in case the tin would melt again at least it would solder itself again It was a mess, the lead battery died (because it's not made to be discharged), the lithium battery still works perfectly apart from the molten plastic shape arround the buses, the best thing about it was that it was very lightweight this new lifepo4 280AH/280A it's amazing, it can deliver up to 3360w and half of that at half charge, more than twice the capacity and it has 4000 cycles Cheers

I wanna point out that I made for myself a portable 280AH 4S1P Lifepo4 12V battery pack (about 3.5kw/h) with a 12V 2500W inverter (everything is about 25kg but everything is inside a tool box with wheels which makes it easy to transport) and though it doesn't have a mppt I could install it, these premade battery and inverter packs are definetly more expensive than making your own Inverter, Batteries, big toolbox with wheels, bms, 35mm2 cable and terminals, lifepo4 charger all cost about 800€ or R 13444,82 Batteries go into the lower compartment and the inverter on top

To calculate how much does every device you wanna use waste I would suggest buying a plug in power meter like this one: I have one of these and it's pretty amazing, you can calculate how much any device you plug in exactly waste on watts at the moment and also the KW/H it wastes until you reset it Basically I would suggest to measure how much every device waste on watts individually (With the laptop put it under stress to know the max watts it can draw) and then plug everything you wanna use on it at once to see how much watts that wastes And most importantly then you should use all those devices as you would for 1 day (or the time you normally work with them/use them) while everything plugged that way you will get an accurate bare minimun of KW/H of the battery you need to last for 1 day All the devices you mentioned probably waste less than 200w combined, maybe even less that 100w but that depends on how powerful the laptop is (Intel/amd/Applem1? number of cores? nm of the cpu? does it have a dedicated gpu?) even with all that objects combined 60-30w could be possible when not doing much with the laptop, it could be even LESS if you put the laptop on energy saving mode Not sure how much a mobile router could waste but if you compare it with phones that uses 4G all the time, it can't be that much, 5-2.5w, 10w max The smaller the light the more battery you get so that's up to you The charging of the ipad and phones depends on how many watts their chargers have (it should be visible in the chargers), they will practically max out at that until they are charged completely, when they are charged completely they should waste differently depending on wherever you are using them lightly or heavy applications or not using them with the screen off And for the fan a small 12v fan should be arround 1-5w, 10w max, it depends on the size and rpms, I've tested normal big AC fans and those only waste 20-40w depending on the speed setting I think it probably will, as long as you put solar panels and you keep watt usage low it your set up wastes 50w continuously then the 555wh battery would last 10 hours more or less At 100w though that would mean only 5 hours, though this is without solar panels, the panels should help immensely, with up to 120W of solar, realistically it won't be making 120w all the time though Hope this helped you, cheers.

I've contacted Pylontech and they have given me the latests versions for both US3000C and US3000B (they say these are actually US3000A or something like that, the update file has US3000A on it) Latest version for US3000C is 2.1 Latest version for US3000B is 2.8 I've updated the US3000C first, but I still couldn't see the amount of cycles the US3000B have on ICC, It hasn't gone into alarm for no reason for now After updating all the US3000B (1.3 and 1.4 firmwares) I can now see the cycles on ICC, so that's fixed Also they gave me latest battery view version 3.0.24 Cheers

Hi, does somebody have a link to the latest update for both the US3000B and US3000C and the latest version of Battery view? (I have some old version that can't read US3000C) I have 2 US3000B from mid 2019, another one bought some months later and a recent US3000C, I have never updated them so they probably don't have the lastest firmware, I do have the necesary console cables I've definitely seen the US3000C getting stuck in protection a few times though it's rare it sure is annoying so if an update will fix it I will do it Also I can't currently see the cycles of the US3000B Batteries, only the US3000C cicles, I think I've heard somewhere that updating the batteries will fix it Not sure if the US3000B need to be updated aswell or only the US3000C to fix all this

Thank you so much for this information, I have 3 US3000B bateries and bought another one, but instead of them sending me a B they sent me a C!!! I had a RJ11 to DB-9 Serial to usb going into a rapsberry pi for ICC Solar, and it wasn't a pleasant surprise to see that they changed the console port from rj11 to a rj45, even if the RJ11 fits It doesn't work on the C Then I had the idea of making the C battery a Slave (and just conect the RJ11 on the B Master) but that doesn't work because apparently the C has to be the master if you have any Bs Anyways I did the cable and it works perfectly with icc, here's a more visual thingy if you wanna make it and wherever your db-9 port is male or female:
