Hi Guys, just a quick question pertaining to this. Is there away you can Set/Adjust the Charge Current for the Batteries on the Inverter? And then, will this override or ensure the Charge Current over the BMS? or What would be the Correct way to go about it. I dont need a 111 Amp Charge Current, and I dont mind if it takes a bit longer to charge? Any advice?

Hi Rudshep. Thank you for the response. Im also thinking in that line. I will be trying to split the trunking between AC and DC and put in a new box for the DC side of things. im scared to replace breakers and fuzes and would like to get some installer to do that for me. The problem is with the inverter, i cannot adjust or change the Charge current. If someone can explain to me how to do that i would greatly appreciate it.

Hi Bobster. It only occurred since I added the 3rd battery. But yes, I will be modifying the setup to have separate AC and DC DB's. However I dont think that would resolve my problem? But It needs to be done anyway. Thank you

Awesome! Ok cool, ill see what i can slap together. I atleast know that the Batts have its own double fuzes apart from the system. Inregards to the essential and non essential loads as far as i am aware they are separated at the main DB. But i understand that it is not feasible to give good advice without full knowledge of the system. What i will do is systematically address and adjust each thing that you guys point out and get the basics sorted. Like what you suggested regarding the separate DB's. Ill get another box for the DC, side spesific. Thanx a bunch! This will be a work in progress.

Hi Jacques. Thank you very much. It looks like you might be on to something, I only have that one DB Board close to my Inverter, and it is connected to my Mains as well as my Solar Panels. So I would need to get that Split into separate DB Boxes and split the Solar and AC Going to the Inverter into two separate DB Boxes, is that correct? I will do that, however I don't know if that would resolve the issue, do you think it might be related? If I do split them, what breakers and Fuzes would I need to place where? If you don't mind me asking. I will then start to purchase the items so long. Thank you for the response!

Good day my fellow privileged Solar Comrades in the South of Africa. I would like to humbly ask for more Knowledgeable individuals to please chime in and help if possible. #Backstory. I use to run a Goodwe 4.6 ES Inverter and two Pylontech 3000 batteries for a fair amount of time( +- 3 years). As of late the current State of Electricity of the Country have made me worried and I was able to Procure another Pylontech Battery, This time a US3000C. I had some issues with Initial installer of the system as he did not do a good job (Long Story for another day). Given stage 6 and all the other problems, me and a mate hooked up the US3000C as the Master, equalised batteries and everything worked like magic. Reconfigured my Inverter to Ecomode cause i wanted to start using my setup more efficiently etc. This then lead to the Issue I was experiencing in the following thread : (How ever, this have been resolved) After resolving the issue in the previous thread attached. I tried to go on my merry way, I however unfortunately started picking up another snag that occurs. Sometime during the day, as Im not at home to monitor I noticed that my PV production drops significantly (I have 12 X 415 W panels), even though there is Load on the system (This then draws from Eskom). Even in broad daylight, where it's at least suppose to power some of those appliances using the PV. When I came back home I noticed my one breaker on me Solar DB tripped. Flipped it back as I thought it might have been just a fluke. However this started happening on a daily basis. Now, im not well versed with Electricity and stuff so its a bit difficult for me, and Im having difficulty finding a reputable Installer I can trust to assist, so i started fault finding again. Turned the system to be in Backup mode and all seems to be well, however im not using the system optimally and would like to get this fixed. Upon troubleshooting a bit and seeing what Im able to do to resolve this. I noticed a few things (and please correct me if im wrong, i don't claim to be an expert.). After installing the 3rd battery and adjusting the Settings to pickup a 3rd batter on the SEMS App, I noticed that it adjusted the Charge and Discharge current for the Batteries. to 110 Amp. However, the Breaker that is currently tripping is a 50 AMP Breaker, the one on the Right that says (Main Switch) (Please don't ask me what it is, i don't know). Now, i might be wrong, but if the Batteries are pushing through more than that or it charges more than that Its going to trip? And here I thought I was cleaver, and wanted to adjust the Charge and Discharge Currents on PV Master, only to find out i cant (Its not allowing me). So I assume the BMS is overriding my ability to adjust/lower the Input or Output Current. So, if there is anyone that might be able to give me advice on what I need to Prevent the Breaker from tripping, that would really be awesome. Even if I need to get someone (an electrician, another installer) out to do it for me, I don't mind, but if I at least can get to the root cause I would really appreciate it. Things that Im currently considering is to go back into PV Master, and to change the settings where I choose what Batteries Im currently running, to only 2 instead of 3, and maybe, just maybe it will lower the charge current or discharge current back to what was? I don't know. Thanx a bunch for any help or advice.

Hi A3jan Im just glad its sorted man, I unfortunately cannot pin point and say with 100% confidence what the exact resolution she applied was. But I can 100% confirm it's not something I did that resolved. It. I believe that they remotely reconfigured the Inverter to "Swap" the settings from input and output. But Im electrically illiterate 🤣

Hi Cef Thank you in that regards, I appreciate it. I have been able to resolve the issue by contacting Goodwe and im so happy about that! I provided them with the information, and they indicated that I was running an older firmware version. She also explained to me that I must not run a CT check everytime I apply settings (Something I didnt know). She the also indicate to me that she will apply a Configuration post Firmware update and that it would resolve the Issue with the Reversed CT check. Im happy this was as simple as that. I also have another Issue that I would like to discuss that on a new Topic. Thanx a bunch again!

Im glad this sorted it out for you, however im sitting with exactly the same issue, and it is frustrating as hell to try and solve this. I followed the above instructions without success. I really dont know what to do. Currently getting fed up as im struggling to find a Installer that is a) Answering his phone. b) sticking around long enough to actually help. So, bit of back ground. Running the ES 4.6 Goodwe Inverter. Installed an additional Battery recently (past two weeks) Currently running 2 X US3000B's and one US3000C (The Master). Had the existing system running like this (without the 3rd battery that i bought recently) for about 3-4 years. Installed the Battery and let it run for a while as I wanted to see how things are going and now i want to start optimising the system, now i wanted to tweak the system to offload some of the Battery more etc etc. Once Applying the Basic Settings it did another CT check. and the dreaded CT Reversed error message pop up. All of a sudden it showed that its starting to Export power to the grid, even though the settings are set to 0. and you know the rest. I tried the above resolution without success. Im at the point where I want to get a Electrician to swap the CT Clamps in an attempt to get this resolved (If it even resolves it). Any advice or assistance would be appreciated.
