  1. Thanks. Just want to add something helpful. This forum was the only place I could find anything helpful. There seems to be a severe shortage of information on the web with regards to Growatt inverters. Perhaps it has the updates. But it was replaced within a week, so I assume they were both from the same batch of inverters shipped.
  2. Hello Power People, I'm posting this here to hopefully save anyone in a similar situation a lot of headache and possibly an inverter. I recently installed a Growatt SPF5000TL inverter and a Pylontech US3000C battery. From what I could research on this forum, firmware updates were required to get the BMS communications established. So, I got the firmware and commenced the updates. It broke my inverter! It would not turn on after the 2nd update. Luckily it was still under a warranty and the supplier swapped out the unit. I was really not comfortable with doing a firmware update on the new inverter, so I found some more information with regards to the cable and managed to get the BMS communicating WITHOUT DOING ANY FIRMWARE UPDATES. So, if you would like to get the inverter and battery communication, follow these steps. 1. If you are unable to make your own CAT6 network cable, go to your local computer shop and ask them to make one up for you. 2. The cable only requires 3 wired contactors. Refer to picture below: 3. Invert the the wires on either end of the cable connections. It doesn't matter what the colours are, as long as they are inverted in order and pin location. 4. Turn the battery off. and set your Baud rate to 9600. Dipswitches 1 0 0 0 (1-ON 2-OFF 3-OFF 4-OFF) 5. Connect the end with contactors 6, 7 & 8 wired to the battery RJ45 port. Then connect the end with contactors 1, 2 & 3 wired into the BMS port of the inverter. 6. Turn the battery on and inverter back on. 7. Go to setting 5 and select Li with protocol 04. Make sure it is set, then press escape and it should start communicating after a few seconds. 8. If it doesn't work immediately, turn the battery off on the red SW switch and then the main switch then turn the inverter off. Wait 30s and turn back on starting at the battery. 9. To verify that it is communicating, got to setting 12, 13 & 21. These will now be displayed as percentages and no longer voltage. You will also see a Li display next to the battery on permanently. I really hope this is able to help someone out there. If you have any questions, please don't hesitate to ask. Neil

  4. Hello Luminous. How did those Jinko's work out for you? I am undecided on the Canadian vs Jinko. They are similarly priced. However I have been told that the Canadian panels are able to operate in low light and overcast situations. Have you noticed any difference?
  5. Good Day, Can someone please help me with selecting and wiring of solar panels. I am in the process of installing a solar system into my house. And have got the following installed and running: 1x Growatt SPF5000Tl Inverter 1x Pylontech US3000C Battery Lights and a select few plugs wired to the inverter (Done correctly by an electrician) Pardon my ignorance, but I would like some assistance with regards to the solar panels. I have been told that 4x high wattage (400W-460W) panels will be more than sufficient to charge the battery during the day. There is no load on the system during the day when we are at work. From what I understand, the MPPT charger of the inverter can handle the following: MPPT Voltage Range: 60Vdc-115Vdc (Max 145Vdc) Default Charging Current: 60A (Max 140A) The battery suggests the following: Charge Voltage: 52.5V-53.5V Charge Current: 37A Do I give priority to Voltage or Amperage when wiring up the panels? Lets assume the panels are 40V/10A, do I wire them: In series to get a 160V/10A, Parallel to get 40V/40A, Series + Parallel to get 80V/20A (I am assuming this is the best option) I have over specified the invert to be a 5Kva, with the intention of adding another battery an more panels at a later stage, much later I would appreciate any assistance with regards to the matter. Neil.
  6. Hello Johan-Henry, Thanks very much. I actually ended up taking it back to the supplier under warranty. They are going to fix it or replace it. there was an issue with one of the buttons that had collapsed.
  7. Hello All, I am having the exact same problem with my SPS5000TL. The fist update worked. When I did the 2nd one, the same SEND: START keeps going and going. Nothing gets sent to the inverter. Even after an entire day of resetting the router by disconnecting the battery, reconnecting than starting the inverter. The screen wont even come on now. The lights on the communication board work though. Does anyone know if there is a hard reset or restore to factory setting procedure? @Johan-Henry can you please send me that FW procedure document? The on I have make no mention of the restarting with buttons procedure.
  8. Good day Power People I recently purchased a Growatt SPF5000TL and a Pylontech US3000C battery. And I am having issues getting them to communicate. There was a post from another member who managed to get the same set up communicating. But it required firmware updates. Does anyone have the firmware updates? If so, please could you send them to me. I would greatly appreciate it! [email protected]
  9. Hello @SiliconKid Thank you for sharing your experience and information here. I have scoured the web as well and your post is the only piece of relevant information I can find on this issue. I recently installed a Growatt SPF5000TL inverter and a US3000C battery. After following your instructions, I still get the errors. I have not done any firmware updates though. Please can you send me the updates if you don't mind? Where did you download the ShineBus app from. The one I downloaded does not allow me to enter the COM port number. I would greatly appreciate your assistance! [email protected] - 074 652 1855
