Hi Guys, Please can I have the firmware updates experiencing similar BMS issues. [email protected] Thanks

Hi, Yes is all worked fine prior to the solar issues. No the installer had shut down the inverter and load etc... then on restart of the sysrem we were unable to get the inverter to use the lithium mode without an error 19. Thanks

Hi Guys, Please can I get some advice ... I have a Growatt SPF5000ES inverter and a plyontec Up5000 battery. I had the BMS working with no issues on the CAN port and dip switches off on the battery. My settings on the inverter was : setting 5 LI ... it then takes you to setting 36 which was 52. This worked perfectly since. I had solar issues which is now resolved. I had replaced a panel this caused my inverter to restart etc in the process and I now keep getting a warning of 19 and a blinking battery. I have no idea how to resolve this and I have been using USE setting to get the system charged in lieu of resolving this. I can't understand how it did work for months ... and just stopped. Any help will be highly appreciated. Thanks

Excellent Guys, after lockdown this going to be my plan of action. Can you recommend a charge controller to purchase? I won't be using solar and utility but either solar or utility to charge the batteries. Where i am in South Africa load shedding Is something we have to live with so on days with bad sunshine , I would manually change it to charge from utility. SBU is my preferred mode. On the unclear comment of mine ... I wasn't sure if the switching and functionality of the inverter would still be operational, if I ventured down this road. Just to summate .... PV connected to external charge controller and connected to batteries. Inverter only connected to the batteries. I will go with your recommendation on the connection. Do I understand this correctly. Thank you to all off you who helped me get much needed clarity. You guys Rock!

Thank you so much, you have really helped me gain perspective. How would I add a solar charge controller to the system. Will I have to have seperate panels to charge the batteries and separate panels on the inverter to supply the home? Will I still have all the functionality of the inverter eg. Charge first then switch over to the solar power? I think the solar charge controller is my only option.

Hi, Thank you, I think I have clone inverter so i think the firmware upgrade is a no go .... How accurate is watch power , as watch power seems to think 52v is 100% on the app on my PC. My batteries get to this but not 54v. Can you perhaps recommend someone to install and provide a solar charge controller to resolve this issue. I am in Gauteng. Thanks

Hi , Thanks ,yes this seems to be my problem. The inverter thinks the batteries are charged but they are not. I have changed 27 to 58. Still did not help. Is there some other way to fix this? Would a separate solar charge controller help? Looking for an ideas on how to resolve this. The solar panels get enough energy but because the inverter thinks the battery is charged it doesn't pull slot as it just takes what it needs for the load.

Hi, Can you please can you correct my understanding. For my setup is fully charged at 54v or 52v. I seem to get to 52v. Thanks

Thank you for the help, I have taken your advice and it's working well. I have adjusted the float voltage to 56v and it charges fully 54v. My load during the day is around 250w.

Hi Guys, I am very new to the world of Solar power, to beat the eskom failures I decided to invest in a system as opposed to a generator. I have a 5 kva Axpert inverter , with 4x 200AH goldshine batteries and 6x300w panels. I am very happy with how this works but I have a few questions that perhaps you guys can help on. 1. Would this charge batteries fully? As they only seem to get to 52v my setting is set to 55v. Does this mean that I require more panels to maximize this? 2. My switch over setting is on 47v , but when this is reached and the inverter switches to utility on resting I still have above 48v. Should I change this setting to 46v? 3. Is there some setting that can help me charge this adequately? I am using this setup on the SBU setting all my other settings are the defaults. Battery more is AGM. Any help or thoughts on this would be highly appreciated. Thanks
