PLEASE make contact with Growatt themselves so they are aware of the issues and also start getting an idea of numbers. Use the Support option on the ShineWifi app, or email them. PM me if you need email address, but I think it is important that they become aware of everyone having issues. Quote Link to comment Share on other sites More sharing options...

Already in touch with them but waiting for them to confirm firmware mentioned here in this thread, so far they have sent me the details of how to get the BMS link. Just need to see if the firmware update is required. Agree with this if we can sign partition with a list of our names I can senD to the Growatt team responsible for Africa Tsa 1 Quote Link to comment Share on other sites More sharing options...
Treschen Posted July 27, 2020 Share Posted July 27, 2020 Okay so BMS cable is in and as described, however now inverter won't charge at full capacity from solar. Battery is at 49.8v but inverter says its 98% charged, the Li symbol does show on the inverter. Also its stops supplying the load from solar and switches to battery setting is SBU Quote Link to comment Share on other sites More sharing options...

Tsa Posted July 28, 2020 Share Posted July 28, 2020 OK cool. That is the latest major versions. There have been BMS specific firmware sent out depending on what batteries you run, etc. This was to fix specific comms issues. BUT saying that I am still to hear of someone running Dyness batteries in Li mode(05) profile L01 and not occasionally getting warning 04 & 20 and the inverter restting/house power tripping.

Treschen Posted July 28, 2020 Share Posted July 28, 2020 1 minute ago, Tsa said: OK 100. What issues are you having? So far the only issue observed is that after battery is fully charged the growatt stops PV from powering the loads (SBU) it then uses battery to power the load even though solar is available. Checked also that charge source is solar. Also when charging from pV it's not charging at full amps, solar option 2 says 8a but it's not configurable. However load kicks in then solar powers the load up to 3.5kw but not the same for charging. Quote Link to comment Share on other sites More sharing options...

Mahone will tell you the same story about the auto discharge safety feature. 3 minutes ago, Treschen said: Also when charging from pV it's not charging at full amps, solar option 2 says 8a but it's not configurable. Option 2 and 11 are overridden when you put it in Li mode and this is now controller by the BMS. That value will constantly change depending on the battery SOC. If you battery gets drained and there is PV available you will see it kick in and the charge value will increase again. 4 minutes ago, Treschen said: However load kicks in then solar powers the load up to 3.5kw but not the same for charging.

Correct but what I don't understand is why it jumps to battery to supply loads after its 100 percent and PV doesn't take over . The solar line also disappears.

Treschen Posted July 28, 2020 Share Posted July 28, 2020 So it's charging at 800 watts let's see what happens today if it reverts to battery after 100 SoC Quote Link to comment Share on other sites More sharing options...

Those that know better might not agree and have the correct answer. But please do ask Mahone this question again and why it is controlled by the inverter and not the BMS. 14 minutes ago, Treschen said: So it's charging at 800 watts let's see what happens today if it reverts to battery after 100 SoC I expect, based on what I have seen my side, that 800W to increase as PV becomes available and your setting 02 to increase along with that. And yes for it to revert to battery once it reaches 100% SOC, but lets see. Quote Link to comment Share on other sites More sharing options...

If your battery is at 100% SOC, then yes. Wondering what it will do when you set 01 to SOL? Still trying to figure what exactly the difference is between SOL and SBU? On the user guide I have it says exactly the same thing... Quote Link to comment Share on other sites More sharing options...

No problem bud,I sent him all the details including video's of all settings and front panel display. My own growatt the older model behaves differently solar is always on. I did notice that this behave only happened on 5000TL only after enabling BMS to the battery and putting the growatt in Li mode Quote Link to comment Share on other sites More sharing options...

This is also in Li mode where I have seen 1) My datalogger stop collecting data points for a random period of time and 2) Had the power trips. In USE/US2 mode none of this has happened.

epnaude Posted August 5, 2020 Share Posted August 5, 2020 just to add to the last few posts. What you see is normal, I have the exact same setup. 5kw with US3000. SOL will provide power using the solar and supplement with the battery during the day, when the sun sets it will switch to utilities a few minutes later. SBU will provide power using the solar and supplement with the battery during the day, however when the sun sets it will continue using the battery until it reaches the switchover SOC setting and then only use utility. I have mine set on SOL and the charge setting on solar only. works great for me. Yes the 100/95% switching between battery and solar during the day is irritating but I still believe this to be the act of the battery BMS rather than a safety feature on the inverter. Nonetheless, I doubt that switching between the 100/95% during the day will have a major issue on the battery life Quote Link to comment Share on other sites More sharing options...
