  1. Hello guys, does anybody have the Deye + Volta warranty document for me please?
  2. Hi guys I have found the answer to this question and thought I'd answer it on the forum for incase somebody else has the same problem The solution is to switch off your phone's mobile data, then and only then will it actually read the 7.2 Max's Wi-fi module. I am almost sure this is because then Android has no other option but to force all communication through the Wi-Fi hotspot, which in this case is the Inverter's Wi-Fi
  3. I am trying to set up the wifi on a 7.2 Max with no success, I manage to connect to the wifi hotspot the MAX creates quite easily, but the watchpower app just gets stuck on the screen which says: Connecting to the WiFi module. It does not actually connect to the wifi module so that I can enter the network settings to actually get the wifi module connected on the router. Am I missing something? Yes I am connected to exactly the same WiFi network as the serial number for the wireless device in question
  4. Hello Solar Assistant This is amazing! Thank you so much for this piece of advice. I have a raspberry pi with me, currently it is called an ICC controller and I have managed to get the unit communicating with both batt and inverter but it does not address any of the problems mentioned. It would appear that your solution would mean inserting a brand new 16GB SD Card and forgetting the ICC software and running your Solar Assistent software instead, which is specifically designed for the King and the Max (our two problem products). You have no idea how much this solution will help us out, if it does work as you say. The idea is to set everything up beforehand for the clients so that they literally just plug the setup in and everything works like it should, hence if it means we have to set up these units beforehand and sell them pre"flashed" with your product on, that would be perfect. Please do contact me at [email protected] and I will more than gladly be willing to try this as a solution. If this does solve our problem, we will be willing to pay licence fees on each and every unit we sell, provided that the fee is reasonable (South African renewables market is cutthroat unfortunately).
  5. Hi Gnome Thank you for this tip, This is exactly what I have been thinking of, but the problem is that my knowledge of actually editing firmware and tweaking values / creating a patch is little to zero, so even if I managed to find the exact cause of our particular issue, I would not know how to translate that into an actual firmware update and unfortunately the nature of our "customer solution" specifically requires an "automated approach", which means that the systems we sell are supposed to be "plug and play" without any issues, hence, the comms between battery and inverter must be flawless. I have actually received a full protocol breakdown from our battery manufacturer, which according to them should be translated to firmware by the inverter manufacturer, but I am unable to find somebody at Voltronix to actually write the firmware for us, if I only knew how to write the firmware myself, I am almost certain the problem would be solved. We have recently acquired a new model, the Mecer 7.2kW Max and would like to launch this product as another kit option with our batteries and to date, I have not even been able to get them to communicate with each-other, let alone, issue free. Any advice or knowledge that could send me in the right direction so I can learn how to write my own firmware will be immensely appreciated.
  6. Hi Coulomb This sounds real good, but the problem is that with 71.94 once you select LiB you are unable to modify any battery settings, so how would one be able to tell the inverter what the low and high cutoffs should be?
  7. Hi Gnome All of the faults presenting themselves are inverter related and not battery related, our battery firmware is also custom patched specifically for Voltronix
  8. Hi Coulomb, we have two units running the ICC, it makes no difference to the problem whatsoever, it basically gives remote monitoring as an extra feature. The king and the PIP5048M is the same machine, if you have access to one, you basically have a king, we reflashed our kings with your patched firmware and the BMS is actually working, it's just that we wish we were able to adjust the high and low paramaters so the inverter would actually stop inverting at say 43V and would stop charging @ 52V, is there no way you could do a patch for us?
  9. We have recently purchased 30x Mecer King's for resale in kits with our own brand of Lithium battery and have flashed all of them with Main CPU 71.94 and Remote Panel 2.49. Some of the units seem to work fine, but here are the major issues we face on the majority of machines: 1. When using the setting LIB, you cannot set ANYTHING remotely related to battery settings, which wouldn't be necessary if the King managed the battery settings correctly, however, the King allows the battery do discharge to 43.2V which is 0.00% SoC on the particular battery we also resell, There is no way to determine/set/program your own high and low cutoffs and when using User Defined vs. Comms Cable, the battery SoC display on the inverter is ALWAYS ALWAYS incorrect. So guess what happens when the Lithium hits 0.00%... The entire system shuts down and the battery goes into sleep mode. Now you have two options, wait 9 hours for the battery to trickle charge and then magically come to life without any warning, or bridge the Lithium with 4x Gels or another lithium, just to wake the King up so it can start charging the flat lithium, EXTREMELY inconvenient 2. When charging using PV power, the inverter charges the battery to 95% SoC, stops charging and will never ever charge the battery again until such a time as you physically reset the inverter, after resetting, it works perfectly until the fault is repeated, this is EXTREMELY inconvenient to clients and should be an automatic process. 3. Our Lithium Batt is completely full (100% SoC) @ 53.4V, however the King would like to push into the 54V range, as soon as the battery hits 53.4V (only achievable through AC Charging) Warning 69 starts flashing indicating the King is being forced to stop when it wants to continue charging, now for us tech freaks this may be nice info te see (obviously if you know what the messages mean), but Clients keep on phoning complaining about an error, which isn't even an error. One should be given the opportunity to switch this function on or off 4. Besides for the normal method of comms, how can we see accurate SOC on the King, but have the power to set the parameters manually? I have been monitoring this forum daily in the hope of a King firmware version 71.95 or something in the hope some of these issues mentioned can be solved? If I only knew how to write the firmware or to who to speak in order to get these issues addressed, I would be willing to give a lot of time and energy to address these issues. ANY assistance will be greatly appreciated.
