  1. I suppose we are paying to be part of the dev cycle, which I expected to happen as they were quite new when I bought. I think they might have bit off more than they could manage, the AM-2 with wall mount installs so simply and its a nice package, and I suspect a lot of batteries went out fast. however I have been extremely disappointed in the Riot, is can be and should have been so much better. But lack of communication, slow ticket responses ( frankly the ticket system is broken) and unpolished releases. RIOT is not looking good based on the feedback above. I still can't see my SunSync data even though integration was done and I opened a ticket.. For me the best part about the RIOT was the ability to make sure the battery is behaving and healthy, now that's been removed too. I use the solarman app more than my RIOT and that is telling.
  2. I bought the system in Jan 2021 Bat1 replaced with bat3 May 2021 Bat2 replaced with Bat4 September 2021 Bat4 replaced with Bat5 December 2021 System currently running on 3&5, I did not note the cycles so can't help there
  3. I have been away from the forum for a while, but it seems my experiences are not unique. I originally bought 2 x AM-2 batteries, and I am now on battery 3 and 5 (4 was also faulty) To my understanding each time it was a bad cell. Hubble have replaced them each time so far, only frustration is the drive to drop off and collect is a pain to schedule. I also have a RIOT and was similarly surprised they removed the SOH details and had a same view as @abeetude why remove it, although It is still available in the details(click on the i). but not in dark mode though????
  4. hi @TrevSo I went into my inverter and it seems to correlate with what you say. To confirm my LiBMS page is set to can bus, so as I understand this means it ignores the values in the box It does get to 100, but often settles to 99%, here is a graph from yesterday just before the system stops charging It them falls back to 99%, but the current remains ±0.02 From the day before it appears the inverter only charges again if the battery dips below 98% as shown here
  5. @Trev is there a reason you not running them off the BMS via can bus? I have the exact same setup and can bus works. Master battery has standard Rj45(LAN cable to Sunsynk) and a second one to the slave battery( correct dip switches setup)
  6. Two members have previously contacted me about possible battery non/under performance and on both occasions the data set appears to support that my batch of Hubble Am-2 are delivering the required power. On the most recent one I gathered the following information over a period we had a Eskom power failure and sun had set. While it is a limited time-frame and averages could throw out the measurements, It does appear to correlate. My Setup is 8Kw Sunsynk connected to a RIOT via CAN and the RIOT is connected to the master of 2 x AM-2 batteries by serial connection. Period 17:34 - 20:11 Solarman App: in inverter data. 17h34 values of 91% SoC, Total Charge 680.80 Total Discharge 624.20 20h11 values of 72% SoC, Total Charge 680.80 Total Discharge 626.50 Delta (626.50 - 624.20) 2.3 kWh Assumed Power used @19% delta SoC (91%-72%) ≈ (5.5KW *2)*19% =2.090 KW ROIT data: I can extract the status of my combined batteries for the same period from the RIOT , the I and V Data is exported to excel and then manually calculate an instantaneous power per reading and sum to see total expected. The RIOT reports V and I readings every 5 seconds. If I take I x V (instant power) /60 min /60 Sec x 5 seconds it should give me the power produced in KVA for each 5 sec slot, sum up the 1800 odd entries and should be total power used. Total sum gives me 2.213 KVA Solar man App graphs ROIT graph While none of these 3 readings match (Expected 2.09 KW vs Solarman 2.3 KW vs RIOT 2.213 kVA) and the whole power factor question in kAH/kW . It is more likely due to the mismatch of data points between the sources and the SoC was closer to 20% than 19. At worst it appears my batteries are working better than advertised.
  7. I used Power-forum store, happy with the service. Steve has very competitive price, its worth a quote.
  8. Had Load shedding twice, last night and this morning. Both times I had to go to inverter to confirm that eskom was actually off, It took over with no noticeable dip/delay.
  9. I'm sitting at an estimated 60% reduction currently, but we have had pretty crap sun for the last week. My initial thoughts is that I might have over capitalised as am not able to use the excess power at this point after 12h00 (could have got a few less panels, or get more batteries) System is setup is like this, but I have now changed it to priority load and grid charge (for bad days) at 16h00, will prob change the two blue values to 30%, there doesn't appear to be a benefit of the stepped approach. (I didn't want the batteries to try deliver over our peak use (stove and geyser 17h30-19h30)
  10. Dam, Web site looks pretty nifty and I had considered them..Very glad I found the forum before I installed. Sorry for your issues.
  11. Its prob still early days, but appears like I need to add an additional battery to make optimal use of my system. On a good sunshine day I am hitting 100% SOC before noon and then the inverter is clipping my production as I cant export. For now I will try managed our habits and maximise the usage, but we will need another battery both from a production and usage case. SOC set to discharge to 30% in stages for evening use and its all used up so far every day. ( I have a ±600W constant load overnight) 27th had a lot of cloud cover
  12. Took delivery of the RIOT last week, The packaging looks pretty nice. Contents of the Box 1x RIOT device 1 x Standard LAN cable (Red) 1 x RJ11 standard cable (Black) 1 x Custom RJ45 to RJ11 (Black with blue RJ45 boot) I was a little disappointed there is zero instructions in the box. So I has no idea where to even start. The RIOT itself is housed in a 3d printed box, nice colour red filament used , the custom cable (RJ45-RJ11) only uses 3 wires. I found some details on the website and decided to try get it setup. (https://www.hubblelithium.co.za/riot.html) https://www.hubblelithium.co.za/uploads/1/3/5/0/135079623/riot_cl_v1r2_provision_draft.pdf Power is via a self clamping Molex type connector (there is 3 ports you only use the outside ones) there is space for a supplied 2A fuse on the side as well. (no power cables are provided) I gave it power directly from the batteries and connected the black RJ11 to my master battery , the provided cable is extremely short and made mounting options rather limited. The setup of the device did not go according to the online instruction, and after about 1h30 I eventually got it right, only to find out I can't monitor anything until the RIOT is linked to my profile. (This is done by submitting a ticket to [email protected]). For now I have the Riot connected and running, with the RS11 cable connected but I cant actually see any info. Hubble also sent me a RS232 to USB cable which was initially supposed to be for the firmware update I need to get the BMS working correctly. It seems there was some comms gaps and Hubble prefers to come to site to do it themselves. This is still much better than sending them back to the factory for the update, but felt odd given the cable was supplied and the supplier gave me indication I would/could do it myself. I must commend Hubble that they are willing to give this type of after sales service, but there is a few things that need improvement in the product side of the RIOT especially in my view, even if it is only better instructions of what to/not do. I was probably a little impatient and could have just waited for Wednesday when Hubble will be on site.
  13. I buy quite a lot form banggood for my RC related items, You have to use the direct shipping option else SAPO will loose your parcel. I have not lost 1 item that is shipped using direct shipping, Use this option then you don't have to worry about customs issues either
  14. Would be interested in the answer as well mine has not arrived but in my conversation with Steve, he said it would use the two ports one to battery one to inverter. I would assume that the rj45 is configurable for RS485 based on this info from info sheet ( would be interesting if this is in factory or in software), but if not configured works in CAN bus mode. The RJ11 is how I will talk to the hubble AM 2 as well for the enhanced info, I assume this based on my need to update the firmware the hubbles and it uses the RJ-11 as a Rx/TX line and you talk via RS232 port. @HubbleLithium can maybe confirm?
  15. My understanding is that you will plug the Riot into the can of the sunsynk and a second cable to the can of the pylontech, no need for a splitter.
  16. Look, I will agree based on how I intend to use, it is over-speced, just ask @leshen about my instance on 6mm for my PV strings. The point I am making is that given that the inverter and battery can under normal operating conditions handle close to 200A it should be a 200A fuse with suitable cable. Putting a smaller fuse in is liable to blow it regularly ( the BMS of 1 batt is enough to blow a 125A fuse according to the LiBMS)
  17. Not sure we on the same page or talking past each other but a 8.8Kw inverter with battery at 50VDC gives a max current draw of 176A, inverter specification for charge and discharge is 190A (thus 200A fuse seems pretty reasonable ), from the Batteries perspective each can supply 100A, so if something went wrong and we start sending more than 1C the fuse would blow too. I also think @ThatGuy comment was more in reference to the fact that I'm only planning on using around 0.5C instead of the rated 1C (or 100A per battery)
  18. Doesn't look like SunSynk has got much of a footprint in Europe, but it is very popular here (South Africa) now. I see that the owner Keith is listed as a UK distributor, maybe worth an email to him?
  19. I had the exact same thoughts, its not fun getting down there however I don't foresee that I will do it often enough once its running. Their response is in the commercial section of the forum. I do still think the top would make more sense, as I foresee most people will install similarly with batteries at the bottom
  20. Quite simple, I want to aim for the 12000 (50%DoD 0.5C) cycle lifetime not the 3000( 100%DoD 1C), Leshan's argument is however valid as I don't void any warranty (of the battery) if I were to use the full capability (1C) and it can deliver the required current without forcing a inverter error or going into battery protection mode. I also have ordered the RIOT for remote monitoring previously, got confirmation that Hubble is sending me the required cable to the upgrade the battery firmware with my RIOT shipment.
  21. It will depend on when you get/got the battery, it might already be implemented. For me , It seems you need a windows laptop with RS232 port and a specific cable that plugs into the Hubble RS232 port (it not a standard serial port looks like a old telephone port). Once mine gets done I will update here.
  22. CoC is done, It appears the Hubble's need a firmware update for the BMS to show correctly in the LiBMS page. I need advice on what to set the system mode on, I have read that the Lithium's don't like a constant 100% top up charge, but I also would prefer not to cycle my batteries more than once a day. What DoD is everyone using, at what C rating? I have 11kWh of battery, but I have set the power to 6000 to limit current (this is my understanding) This is my current settings SoC graph, you can see the top up 100% bounce around 12h00- 15h00, and the discharge and charge after 15h00- 18h00 What I would like to achieve, Make sure they are full before night (95%), discharge at a limited rate up to max 30%, then start to charge again until full.
  23. Left to be done: Need to confirm if the BMS is working correctly, and the hubble's are talking to each other (discharge limit should be 200A with 2 batteries) Need to figure out best times/percentages for battery use. Get CoC done. Produced 34kWh today. Production/usage for the day
  24. Installation was completed on Saturday 12 JA Panels Inverter , Batteries, PV combiner/fuses, AC DB , DC Fuse and breaker and ENB Main Screen Peak solar Overview BMS
  25. Cant really say that I paid for these about 4 weeks ago, so I knew they were coming before "the Thread" Since there is a quite a lot of interest I will also be sharing the experiences with the batteries once its running. The batteries were pretty well packed, came with a "quick guide" a QC date, and a set of 25mm^2 cables First three pages of quick guide
