  1. Hi everyone, I had 3 x Pylontech US3000B's installed 3 years ago with my solar and recently added another one. However, they only had the US3000C version now. I now have 4 batteries, 3 older ones (B version I think! - bought in 2019) and one newer C version one. Few questions: - the C model Pylontech seem to charge fully before the other one's. Is that right? ie - would it not overcharge if the other 3 are not fully charged yet and they keep charging? - all 4 of them are connected to each other with the short black BMS cables that came with the batteries and the top one (the C model) is connected with a network cable (in the A/CAN slot) to the Sunsynk inverter. From this, the Sunsynk inverter can 'see' the batteries as they show up in the LiBms display on the inverter. The comms cable used to be plugged into the bottom battery (the b model) - all still connected to each other - but the Sunsynk does then not see any batteries/does not pick it up). Is it ok to leave it in the top battery - does it matter? Views?
  2. Thank you everyone - these suggestions are all great. Being new to this, it's great to also learn about other interfaces, software and other monitoring options available. I spoke to my installer and he was very happy to swop it out for a Sunsynk logger to which he managed to also help me with access to changing the settings remotely. Looks like I am sorted for now and will also look at the other monitoring software and options mentioned!
  3. @Nexuss - Sunsynk support came back saying they are not able to grant me access - it's only available to installers. I did then try and ask them to help me but they did not seem to want to. Could it be the Solarman logger that's making them say that? Or, does anyone perhaps have a contact name/email address of someone at Sunsynk that could possibly assist me (or please PM me the info)?
  4. Ah, ok - thanks. Will wait to hear from them and update on here as well.
  5. @Derek Ramos Any difference you are seeing after the upgrade?
  6. Ok, thank you - let me try that and see. In your second last sentence you refer to a new logger that can do remote control. I want to make sure I understood you - do you mean that on newer hardware version loggers this is available by default and that I perhaps have an older hardware version? I am trying to understand whether this is a hardware related matter in that my logger may be an older version where I need to ask Sunsynk to enable for me?
  7. Hi everyone, I recently had a Sunsynk 8.8Kw installed (few days ago). This is a second hand unit to which I also received a SolarMan wifi data logger. I understand the unit to be about 8 months old and assume that the logger got sold initially with the unit. I downloaded the SolarMan Smart App and the Installer helped me set up my profile. I am able to remotely view the state of my system which is great. I was hoping to be able to remotely change settings, eg when loadshedding is announced etc to change that batteries are charged at a specific time and then de-activate that remotely as well when needed. However, I don't seem to be able to do this remotely. I did see on other threads that some people with a SolarMan wifi data logger do now have the option (seemingly after an update earlier in the year) to update their Sunsynk remotely. I only seem to be able to view. Would anyone know whether this is 1) as a result of me perhaps having an older SolarMan logger preventing this functionality 2) or could it be my profile and how it's set up (ie, should the installer change me to a different kind of user or need to make me eg administrator) or 3) could it be software related (Sunsynk inverter or the SolarMan wifi logger software?) - or perhaps something else? I would appreciate guidance and recommendations on how to troubleshoot and solve?
  8. Great thanks so much @ebrsa - does the model of Raspberry PI matter or which one is recommended for this?
  9. @pilotfish thanks so much for the comprehensive feedback and graphs - it looks interesting and you are correct in that one should manage this system better - which is what I am hoping on doing. Hopefully little to no damage has been done to the batteries. I would most probably need to get someone to come and help me set this up - thanks again for the feedback!
  10. Thanks Peter for the detailed feedback, I apprciate it. I will have a look at your recommendations and read up on it more, thanks. I may need to have my system independantly evaluated as none of the heavy lifting items you mentioned here is connected to my system. My geyers, aircon, washing machine, tumble dryer, pool pump, microwave etc - is all connected to Eskom. I have 5w led downlighters, 3 tv’s and 4 fridges that runs off the system and it doea not make it through the night - which is the main reason I want to access the system info to assess it myself. Thanks again.
  11. Thanks so much for the feedback - I will have it looked at once I have done my assessment. I appreciate it.
  12. @plonksterThank you for highlighting that - much appreciated - what does that mean though and should I do something about it?
  13. Hi everyone, Newbie here - would appreciate some help and advice. I do not know a lot when it comes to Solar and need help accessing the energy produced and consumed by my solar system to optimise it's usage. I am attaching pictures of my setup - not sure what other information may be needed? Here's what I have: I think I have 3 x Axpert inverters (from the pictures other people posted) - can someone confirm? I have 18 x 200ah batteries - if I remember correctly I am running a 48V system I have 24 solar panels (need to check and find out their specs) Here's what I would like help with please: I would like to access my system through a computer or smartphone. With what I have, is that possible? If yes, what do I need? I have a spare Mac Mini I can hook up to the system. Or, I see people are buying what looks like Raspberry PI's and connect them - I can also do that if that's the best way to do it I only have wifi in the area and would need to figure out a way to connect everything to the wifi as there's no LAN cable (though I can try and make a plan) I have a desktop Mac at home and am not sure if that could work to access the system remotely? Is that even possible? I am trying to monitor my energy consumption during the night initially to see how I can further optimise as I don't seem to get through the night as I find the system fully charged every morning through Eskom during the day - when the batteries are full and so I can investigate to perhaps move stuff (ie pool pump at a specific time) to be moved over to Solar during the day if the batteries get full early enough etc have a general view of the generation of electricity and it's demand The demand from the house from around 5pm - 10pm seems to be high as the system do not make it through the night without recharging through Eskom at some point and that concerns me at the moment as I am investigating either increasing the system or finding a way to optimise consumption from the house. Is there anyone who can help me create a set up so that I can monitor my system closer? Thanks Willie
