Glad I could assist a little , and that you managed to come right . Still love my Goodwe its now installed in my holiday home . been running since 2014. Paid its self back 3.5 x all ready in energy savings alone..

410-00468-06.zip have the prevoius 06 in this lot aswell .. goodluck

Ok so my inverter model is different to yours I have the 5kw unit . I speak under correction but i am not sure the 5 kw will be the same as the 3.6.. so my firmware i have is not the same. 410-00468-07X.zip

g'day fellow installers. ANyone know where i can find Alpha ESS Batteries from in SA

Thank You CEF. I'll install next week when back , also now away from home for next few days( year end rush)

@CefGood day to you . I would very much appreciate the software so I can real time monitor. I will, as soon as i get the software , look at the readings and then maybe start looking at opening the unit up Thank You in advance .

Agree. but when one has variances .. and not the same answers the whole time when you ask the questions..... one has to wonder ..But why... now there is 15w of power on the DC output.... ( have 300% increase)...I need someone clever to reset the whole inverter.. and want to see the DATA CEF program can show...

@Bobster. I's till trying to getto grips with this.. I belive your quite of SH is quite apt however...Phaedrus is credited with saying, “Things are not always what they seem; the first appearance deceives many; the intelligence of a few perceives what has been carefully hidden” . Some more info. I have managed to reload latest firmware. The batteries are now charging at double the speed the did before. from 5 w to 10 w.. ( WHAT?) so I'm doing a couple of cycle runs. PS I wonder if the actual CT will play a role in all of this .. eg Sunsynk if the CT is not working correctly ... the the system goes wonky... still if anyone has a contact at Goodwe ( maybe abroad) that might be willing to look at the data.. please let me know. Thanks PPS @Cef Please if / when you available to respond to my request re the software.. much appreciated.

any You have a CT installed to regulated the power flow and direction

Hi Bobster. Let me start by adding more details as per your question / possible issues. The yellow inverters does not / cannot be supported online by Goodwe. This this avenue is closed. The BMS on the yellow inverters are very limited to few brands of Batteries. But not even that works properly. So I've managed to pair with Pylontech via an ezconverter Box and that worked perfect. Untill now ( 5 years) The discharge works 100% shows the correct amperage drawn on the App and testing with a Tong tester ( and verify when i log into the Pylontech battery BMS Software) so its not the EZ CONVERTER So to make sure its not( again just in case) I've now gone donkey mode... 48 v Dumb Battery mode with no BMS working on voltage mode.... ( like before i bought the EZ CONVERTER) It makes no difference in what mode(any of the 4) I have my Inverter. The results are the same regarding charging the battery SEMS long term not available for data logging as my system is setup on our farm- NO connectivity in the bush- (In the Eastern Cape ) since 2018. I am running test right now here at home in PE Batries was fully charged external. On a farm so we have many power outages even before load shedding was an issue , as we are on the end of the transmission line -so yep always an issue Yes Batteries run flat , when no eskom , and at night , self consumption/ fridge , etc. . So I had to make use of a External MPPT to charge the batteries up. Problem is I'm not permanently on the farm so it could be an issue for my fridge... Hope this to clear things up.. I'm actually wondering if the software from CEF might not shed some light on it .. or maybe there is a test one can run to see if there is not a relay ( charging) that has failed. I have managed to source 3 inverters from insurance cc ( am willing to heck parts out of them .. but have not idea what board to be the charging board. Maybe someone has some more technical knowledge than me that could help with circuit diagrams or have a good contact at Goodwe that might be willing to part with this info. as I said Goodwe is not at all willing to help, as its out of warrantee. Its easy enough just to buy another inverter, but for the life of me, this small little issue must be rectifiable. It performs/ed brilliant and hate to just bench the unit. Current SOC is 90% ( Unit is now at my home in PE) where I have internet so I can try and resolve this. I temporarily installed an axpert inverter just to keep the lights on in-case Eskom fails again "Can you post us a graph from SEMS showing when you think it should be charging from PV but isn't?" Please look at attachment I put it on my network at home , currently discharging Historical Data Export-20241120200604.xls

Good day Power Forum members. My inverter for no apparent reason just stopped charging the batteries. Its out of warrantee and unfortunately Goodwe is not having it to assist in repairing the unit. Every else works 100% as it should. Feed to grid from solar OK Discharge batteries when not enough solar or loss of grid . OK only issue no battery charging not from grid and not from solar. Has anyone issues like this before and if so how to i get my inverter to charge batteries again. Its the Gen 2 Goodwe ( Pre 2018 no ARM) Yellow Inverter I have even downgraded the firmware .... to vs 2 and back to vs 07x ( latest) Nothing.

is this for the correctional services tender?

I know this has been covered but can't seem to find the post. The INIFINI Inverter Range (Green Machines). Who has Software/ Hardware that one can monitor them? I know one can just set the batteries ( Pylon) to Voltages but setting up with a Pi is better in the long run. Thanks in advance

Thanks All for your input .. I've seen too many inverters POP due to miscalculations. and more so because of amps. but if you say this is the done thing.. Then so be it .. Thanks again.

Hi All. Apologies if this has been asked before. I Tried searching for content but could not find it. Inv Spec: 4500w PV 120V Min DC 450V Max DC 18A Max Current. The last is the concern I have many installations but never have I pushed limits so close. would like your input, please. The subject inverter currently has 9 x 335w panels in a single string ( VOC 416 DC) The client requested 12 Panels ( VOC 555 single string too high so split string 277vDC) But the amps will now go up 17.7 A(Imp) Is this safe / recommended? Your Thoughts?

Can any one assist .. i have never had this error before.BMS is communicating correctly. I have tried to get hold of supplier and support .. no responce . Thank You J.

Good Day all. I need some quick input please. I generally research myself but I'm just checking my facts. MUST inverters do they have the capability to coms with Lithium batteries Inverter Type: MUST High Frequency On/Off Hybrid Solar Inverter PH1800 Plus Series (2-5.5KW) Battery Type : CFE 5100 S Online Monitoring capabilities ? Thanks in advance

Thank You for info. Note the systems we are talking about are the individual with cash flow as a problem, not a bank balance problem. Think more the like of the commercial sector. So there electricity expenditure is like 10k-100k plus so they willing to put this money to good use. eg for next 5 years pay this but then out right own a system. I will make contact . Best Jay

Hi fellow Solar Installers. So more and more people want solar , but they want to go the financing route. Any of you used any institutions for this and what is your PERSONAL experience. Some numbers/ names will be great. Yes I did tell them go to the bank. But they don't know who to call at the bank. so I'm trying to get a list of all banks as well. Maybe make this a sticky note.

Thanks Riaan My thought process on the same track here. Many end users now challenging us as supply and installers as to why our pricing is not on par with the "new" kids on the block. Even the used or second life batteries .. if you cant determine the actual SOH, how would you know. There is the old school way .. by doing a physically load test cycle but that takes time.. and most clients not going to "pay" for a pre install service Nor would the supplier allow you to test prior to sale .. Next big scam is on our hands here. I just thought maybe someone has a solution. But now you say the counter can be reset. Oh no.

I did try and search to see if this has been a topic of discussion , so if there is and I did not see .. I apologize ..pls send me link if not then please read on. So I've been in the industry for a few years now and I've seen "installers" come and go and new ones pop up and all but here is a new little thing that has started rearing its head. There are people selling "used" Lithium batteries as new .. .. Neatly packaged and all. So .. How do we really now the Cycle life of a lithium pack. are there software / hardware available to do this. here are some variables: 1. Battery with Compatible BMS plugged into an Inverter that can "read" the count of cycles including SOH 2. Battery that does not have BMS or not compatible with inverter to give this info. So my question is. is there such a device/software that one could use to determine the age/status and the SOH of the battery May even pull a log of cycle data. Thanks J

Just some feedback. i ended up installing a UPS .. the only thing i could do , Thanks again for your advice.

Hold a sec. Must it be LAN? can i use Wifi?

@BeylieI tried the Part 1.. no go.. ill try part 2 tomo..let you know. Shot for assistance.

I have now tried everything bar changing the inverter. I might install a online UPS for the one appliance.
