Oggi è la prima vera giornata di sole, ho notato che l'inverter si è riavviato più volte. matte la schermata di errore

prima che fosse scritto DC current high

I opened a ticket to goodwe, today they fixed me, they set the inverter remotely, I haven't had any problems since today. thank you all for the support. I have to say they were quick to respond .

@abrax With all due respect, I think some concepts are mixed.
The screen you show in the post does not indicate any Goodwe error. The code "0" appears in PV Master (I show it in my software taken from the Inverter log) when an error condition disappears, that is, when what was an Alarm condition for the inverter firmware is no longer present.
For example, the Alarm: Nº: 512 (Utility lost) when there is a power outage of the grid generates a condition that persists until the electrical service returns to your home, where the code "0" appears.
You understand ??
In the Error Log I identify different types of Goodwe's own Alarms, status changes of internal variables of a logical type, and situations that, due to changes in the operating parameters, I estimate may be of interest to Advanced Users, as well as certain actions of the user.
The Goodwe alarms/events that you can check in PV master in this software appear in yellow letters with a red background.
If you have what you think is a problem on your Goodwe, it would be nice if you would make a separate post of this thread, so that many Goodwe users who do not use this software can give you feedback and/or benefit from solving the problem you are having or do you think you have
It would be important that when you create the Post you make screen copies of the error that the PV Master shows you in the android application in its own error log.
In this forum you will find many people willing to help you but in general they will answer you if you are clear in the presentation of the problem.
Regards !

guys, i'm waiting for someone to help me, but no one is answering me. I don't see the data as I already told us in the post above

 

Good day to all,

I want to thank CEF for the excellent software he has created, with many hours of work.

I have used the software on my new windows 10 laptop and it works great.

I have an old laptop with windows 10 32bit  processor I want to use always on for remote monitoring.

The problem is I cant install because VFPA RUNTIMES 2019.07.18 gives me an error( not supported by processor).

Is this software only compatible with 64 bit processors?

 

Paulo from Azores 

it works great on 32 bit as well as on 64 bit

Is there a way to monitor charge and discharge cycles?

As far as I know, at this time Goodwe does not request this information to the BMS for compatible batteries. Ideally, it would be possible to have a separate app for each battery model.
If monitoring 24 hours with the software of this thread, it would be interesting to consider a simple counter, in an future review, for example in case a charge cycle is considered if the SOC dropped below 70% on immediate discharge previous. The other inconvenience that could be solved in an approximate way, is that based on the State of Health of the Battery (SOH), each user could calculate the cycles already accumulated according to their brand and model, which would be taken as the initial value of the counter register. Thanks,  It's a good idea, it would be  very simple to implement.

hi, new to this side, i have just got installed 5048D-ES and i have no way to monitor the system, i cannot reigister the inverter on sems it say's the plant is already in use elsewhere, i think the electrician did it but didnt give me the details for it, anyway, this thing Cef has made looks very good,  question is does it take up much space on my computer and slow it down? ore is it just an easy running thing, im not good with computers ore anything but will try this, thank's

is it just me ore, it stop downloading at 68.mb and say network error, tryed many times always the same

Hey @Cef Great to see you are still evolving this software for everyone who is using it. Just wanted to give you an updated on my project with the 3 x SBP 5000 inverters - which although not directly related (being AC coupled inveters only) relates in respect of using the same AA55 protocol that you are using for communicating with the inverters

I use Node Red for my communication and control of the inverters and have been doing so for the last 2 years or so with no issues.

I am not sure if your plan is to provide control as well as monitoring of the ES series but if so i am happy to provide you with all the info i have in terms of writing to the inverters (By IP Address in the case of multiple inverters) and being able to control what mode the units are in and the the different time settings.

I have found this to be very reliable unless we have storm and we then often have failures of the GoodWe WIFI modules.

I currently write in realtime to the inverters and tell them how much power to charge and discharge at any point in time (we are a 3 phase house and GoodWe do not support multiple inverters in a 3 phase scenario so have to manually control each inverter on the 3 phases)

Let me know if you require any information in relation to this - it was all hard won by packet capturing everything that PVMaster was sending to the Inverters when changing modes and times of operations and then charge and discharge limits.

I will be shortly biting the bullet and moving all of my control over to the modbus port (again through Node Red) but happy to share in the meantime if you want the information

Tank you very much for your ofreciment. The project continues with progress, although in recent times a little slower since I have been with a lot of work
Sorry for the delay in responding, which is for the same reason.
I would be very interested in your progress in writing commands with the aa55 protocol, although remember that the ES Series is not MOD BUS. It's just aa55 over UDP.
If you could share the information you have with reference to:
1) Command aa55 to configure Economic Mode and mode of passing the values of days and hours of charge, discharge and their nominal %
2) Command aa55 to perform a soft reset of the inverter, after programming the Economic Mode and/or changing to any other operating mode, so that the configured values are effective.
3) Command aa55 Allow/Disallow export to grid and set max value.

I would be interested in this, because in version 4.20 that I will soon publish I implemented a Weather Widget extracting data of interest from Solar Systems specifically, such as the time of solar Noon and the % cloudiness and it would be interesting to make automated processes in such a way that the inverter changes its mode of work according to weather conditions.

 

If you want, you can send me your interesting research privately.

Best regards !

 

 

Hi @Cef thanks for your hard work on this especially for the small community of GoodWe users, my GoodWe started randomly tripping about a month ago, I though it was my Gel Led Acids, so i finally took the plunge and purchased 2 x 5KWH SVOLT batteries (which are working great) but still random trips. Hoping your software can help me out

Great job. It looks good.

Buen trabajo. Se ve bien.

I just installed it and it asks me for a name and a key. Where do I get it?

Hi All,

Setup:

• Inverter GoodWe GW5048D-ES, Firmware: 232315, Software Ver: 410-04025-23, Arm Version: 410-02034-15
• 18 x 365W Canadian Solar Panels (6.5KW of capacity)
• 2 x SVOLT 5.09KW Batteries (Inverter communication set to Pylontech US3000C*3) closest config to my setup, SVOLT uses PYLON protocol for comm's over CAN protocol. The SVOLTs are a replacement for my GEL LED Acid system that was installed in 2020, along with the inverter.

Issue:

1. I installed an AQUAHEAT 3.5 (https://www.aquaheat.com/_files/ugd/01bcb4_77d00c7b0a67474d883f899c6403464d.pdf) power draw of this is only around 0.87KW and hence is connected to my backup circuit of the inverter.
2. In June my inverter started randomly tripping during the night when there is load shedding and I am on battery backup, the tripping stops when I turn off the heatpump.
3. Given I had been running gel-led acids up to this point, I decided to upgrade my batteries to lithium (finally) - the SVOLT batteries were the most economical and work with the GoodWe (as specified in their technical guides) - this is technically true. Still, GoodWe's battery configuration for 3rd party batteries leaves MUCH to be desired and they don't respond to support emails or pick up the phone anymore (is GoodWe as a brand just dead now?)
4. Anyway, for some reason we just did not have loadshedding during the night for about 2 weeks and in the day I dont have any issues as long as there is 1W of solar coming in the inverter does not trip, ever.
5. Recently, we started having loadshedding from 18:00-20:00 and 20:00-10:00 and since then the GoodWe just trips constantly if the heatpump is trying to heat up the geyser.
6. The total load on the inverter is 2000W (with the heatpump), batteries have 190A @ 48V 10KW of discharge capacity (way more than the inverter can handle) and still is trips.
7. My initial thought was maybe some config or error being thrown by the batteries, so I hooked up a BMS monitoring app with my laptop and monitored the batteries during these trips and nothing, no error is thrown, no communication loss nothing, even removing comms and putting the batteries in self-define results in the same.
8. SO, maybe its the GoodWe, i used @Cef tool and started monitoring the inverter and what I see does not really make sense, I get an error 15, Load on trip was 1230W or 1365 Va, Batteery is at 49.60 V or 92% SOC (22Amps draw). Error Goes 15 (Trip) -> 10 (Restarting) -> 9 (Check) -> 12 (Normal Off Grid)

Any thoughts on what could be the issue? Is it just GoodWE?

Edited August 27, 20232 yr by RavRabbit

Are you sure the electrical connections to the heat pump is not the problem? It sounds like it draws more power than the inverter can handle (20 amp + 10 amps for 10 sec). 

There will be a spike when the motor starts, but should not be anywhere near the inverters threshold.

Can you run your inverter at 20 amps without grid power? If you can then I don't think the inverters is the problem.  Cefs utility has an alarm that warns you when an excessive current is being drawn, does that happen when the heat pump starts up? 

Good luck finding the fault.

Hi @RavRabbit

1) Error 15, as you will have seen in its description, is recorded when what happened to you happens to you, this is "a trip". Goodwe's software (PV Master) does not record them.
This is the information it records (event log):
Error_Info="Warning!: Loss of BackUp loads"
Error_desc="Device trip, otherwise check the connections downstream of the B.Up output"
This error can also appear in the event that the Backup Output of the inverter does not detect any load (for example due to a short circuit downstream of your current inverter).
The values you see, which don't seem to make sense, are due to the failure audit event saving the electrical parameters an instant before "tripping". Unfortunately, since Goodwe's motherboard circuit boards do not have any type of battery, the inverter loses all communication instantly when a trip occurs.

2) With reference to the failure of your Goodwe, it may be possible that you have one of the 2 charge/discharge circuits burned. Each circuit handles a maximum of just under 50 amps. Verifying this is simple. With a good solar production and being connected to the Grid, you will be able to see when your batteries are charging, how much is the maximum daily charging amperage. If this value is greater than 50 amps, you probably don't have this problem. If the battery charge does not exceed 50 amps, it is almost certain that you have one of the circuits burned. You can see the maximum daily value of charge amperage in this sector of the main screen of my system (orange background and white letters).

Edited August 27, 20232 yr by Cef

thanks @BGb - the heatpump has been checked and it generally functions normally when the sun is shining and there is no grid power.

the heat pump's startup peak current is at most 2000W and my general house load is 1000W max (mostly lights, fridge etc) so at most 3000W.

The inverter handles my coffee machine, microwave etc perfectly fine when the load reaches close to 4000W so it should be fine

Thanks @Cef - my battery charge seems to reach 3.6KW ~ 70Amps so it think both circuits should be working normally. the inverter is able to handle much larger loads without issue - i think the heatpump is posing a specific inductive load that the inverter just does not like.

the interesting part is that if I am generating more than 50W of solar the trip does not occur, tested it a few times this morning between 6 and 7 AM 😕

Very good job, I would like to try with my goodwe es5048

Good morning.
I had an axpert max 7.2 inverter mounted in an isolated country house with 8 Jimko 465 panels, originally it had a 48NPFC100 battery, working correctly with ICC software, but without much autonomy. At this time I had the opportunity to acquire 16 Narada 12HTB150 agm batteries working ok. I installed the 48NPFC100 battery on a goodwe 5048ES. configured in selfdefine with DOD at 20%, giving me a lot of problems, it disconnects, the battery runs out. There is some possibility that the CEF software can help me with the correct configuration and operation of the installed battery.
I would appreciate your comments

The first thing I'd do there is get a spec sheet for the battery, or see if you can get all the settings from that expert. Then go through each setting on the Goodwe and check it against the spec/previous working figure.

Better still would be to get comms in place between the BMS and the inverter. But I can't help you with. Maybe there is a specific Narada setting on the Goodwe, or information from Narada on how to make a cable that will work with the Goodwe.

There isn't. 

But the Goodwe doesn't know about my battery. The battery is a FreedomWon. Fortunately it knows all about the Goodwe, so once you have a proper comms cable made up, and the inverter in "default lithium" mode, the BMS tells the inverter what settings it wants.

Gracias bobster.
La 48NPFC100 no es compatible con goodwe 5048ES, tiene comunicacion por RS485, y el soft ICC no es compatible con GW5048ES. he puesto los voltages de carga segun 48NPFC100, 53.5V, DOD solo 20%, pero el equipo continua descargando la bateria.

Thanks Bobster.
The 48NPFC100 is not compatible with goodwe 5048ES, it has RS485 communication, and the ICC software is not compatible with GW5048ES. I have set the charging voltages according to 48NPFC100, 53.5V, DOD only 20%, but the equipment continues to discharge the battery.

I apologise. There's an error in my replies. I'm saying "Narada" when I should have said "48NPFC100". But you seem to have already done what I'd thought of.

I intially had a different brand of battery. This battery could not communicate with the Goodwe, so self define was used, and that worked, sort of. The battery was never entirely happy. But this may have been more to do with that particular battery than with the Goodwe.
