Very good @rowesley ! It would be good if once correctly tested you could share your circuits.
Regards !

I present my solution, in the circuit that you can see in the image, to be able to connect 2 Strings to a single MPPT input of any power inverter, in my case East string and West string with automatic switching at a time close to solar noon to the PV2 input of my inverter.
I have a Goodwe ES5048 inverter, for those who don't know, this almost 5Kw inverter has only 2 photovoltaic inputs (2 mppt) for 2 strings.
The idea arose a little over 2 (two) years ago when I wanted to expand the area of solar panels to increase my solar production but I found myself with the problem of not having more space in my house to install more panels to the North.
I was not interested in buying another inverter to have 2 more mppt, not only for a matter of physical space to install them, but because the Goodwe is not parallelizable with other equal ones and the fact of having to modify the electrical circuits of my house downstream of the inverters was a resounding "no" for me
I have very good roofs at home to the West and East, so I began to investigate if there was any commercial solution for this purpose and I did not find anything.
I designed this Circuit that I present to you now, but that I have been working at home since March 2021, exactly tested for 2 (two) years, working perfectly with the DC RELAY Values that appear in the photographs of the Real Board installed in my home. It has been tested in all temperatures and conditions.
Before March 2021 I tried other 40 amp relays but they got too hot and I was afraid they would burn out. That's why I bought these that are 150 Amps and with the suggested aluminum heatsinks, even in the middle of summer with temperatures of 40 degrees, the heat dissipated is not high.
It's a very simple circuit that anyone with an idea of elementary electronics/electricity can do.
I could comment much more about it, but I prefer that you ask the questions that may arise.
The relays and their heat sinks can be purchased on aliexpress. From 600 Volts DC they have up to 400 Amps.
The timer can be purchased at any electrical/electronics store for a DIN board. It only matters that you have a Normal Open contact and a Normal Closed contact.
The other thing that is needed is a low voltage DC source to open or close the relays, it can be from an old cell phone since it supports more than 5 Vdc.
Really for me it was a solution that I am very happy with. None of the relays have burned out in two years of use. with an investment of a few dollars, minimal compared to the benefit it brings.
The scheme is self-descriptive, so as not to lengthen this Post.
 
 

Hi .
In the download area of the forum, a new version is coming. I will publish it shortly.

I present this program that I share with you in its VERSION 2.0. It is only for Goodwe Series "ES", that is, for GW3648D-ES and GW5048D-ES.

It has been developed solely for academic and hobby purposes, without any commercial objective.
With reference to Version 1.0 of the download area of the forum, beyond the correction of errors, small aesthetic changes, elimination of erroneous information from Goodwe itself (e_day and e_total), the self-discovery of the Power Inverter within the LAN network and adding battery self-defining parameters, I found it interesting to focus on one of Goodwe's weak points, which is the error log.

Like most users who have experienced them and beyond the degree of technical knowledge, I would have liked Goodwe some more information when a "trip" occurs due to different circumstances during the use of batteries, normal operation or provoked with reference to The Working Load and Maximum Powers allowed, either in essential or non-essential loads or in both.

The operating parameters in the event of an error, the SEMS PORTAL shows them with 1 (minute) between data, a true eternity, this is of little use and the resulting query is frustrating, generally.

Trip events ARE NOT REGISTERED by GOODWE, at least not in all circumstances from what I have seen.
Goodwe records some events that are of some use, but there are not many. These can be consulted in the PV Master application as you already know and with a descriptive text. In this system that I make available to the PowerPhorum community, the option * Error / event log * shows the GOODWE events registered in PV Master, whose code I have been able to associate with a description in red letters on a white background and with the In order for this to have a greater sense and utility, I have added to this register the fundamental parameters of Operation at the time of the Device Error, such as Temperature, Apparent Power (workload), Effective, Voltages, Loads, Batteries, etc.
The rest of the Events appear with the name "System", of these there is a group in black letters and a red background that are the Reset and Trip events, because when Goodwe is reset it does not leave any record. To partially solve this, the parameters that I show in these cases are the live values taken "1 (one) sample before the event", that is, if the update of the live data you want to set it to, for example, 1000 milliseconds and The this system finds that Goodwe rebooted at 10:25:30, for example, in the Event Log you will see the live data logged up to 10:25:29.
To be more accurate than what the Goodwe readings give, if you have higher precision instruments than the device sensors, for example with external AC meters like the Eastron SDM series,Carlo Gavazzi, etc., or for batteries using a multimeter or with a Victron BMB600 or BMV702 connected between the batteries and the Inverter, in the OPTION "PARAMETERS" the AC Voltage values can be corrected and, on the other hand, Current or DC Voltages in the state of charge or discharge of the batteries in +/- to the hundredth of a volt or ampere. In this case, in the "LIVE DATA" section of the left panel, the parameter with the [c] indication will appear. If you accept the direct Goodwe values without any correction, just leave the values at "0", I have also added the Goodwe "Self-Consumption" Value for better precision in energy calculations. My device draws between 60 and 66 watts, which is more than the manufacturer reports. You can adjust other values for greater precision that are self-explanatory.
They will also have an idea of the actual maximum daily PV voltages and amps under load conditions (V imp and A imp) of each string, which can guide us to make modifications to our strings by pushing a little further towards the Goodwe limit in a more safe.
The maximum daily values of some parameters appear on the main screen of the scheme. I emphasize that to update a maximum value, internally I consider it only if 2 (two) consecutive samples are higher than the previous one, this in order to avoid peaks due to AC harmonics and / or other electrical disturbances with very instantaneous peaks.

Your comments and suggestions welcome!

Thanks Cef, installed without a problem it looks great and the weather widget works fine. I need more time work with the utility for the momen the focus is to see how best to extract the data (the dark background and figures makes it difficult to read), the 3D bars and legend seems the clearest for hourly data.
Thanks again, its of great asssitance.

@BGb
Well, the truth is, I haven't received much more motivation from forum users to continue uploading subsequent versions, and I'm struggling to prepare a new one so it looks good in the forum's download area. I'm sending you a Google Drive link where you can download a fully functional version, although not the one I'm developing. It may have a bug that I'd appreciate if you could report to me. In the "Events" tab, you'll find a bug in a feature I'm implementing, but that doesn't work well yet, related to unexpected photovoltaic power outages. The idea is for the system to alert you with an audible alarm. I had an arc flash in my installation due to a dubious MC4 connector I'd had since 2017. A fire started in the connector while the arc flashed until the power to the entire string was cut off. The idea behind this feature I'm working on is to at least warn you and give you the opportunity to react in time if a fire breaks out on your roof. This guarantee of at least one loud audible warning can only be achieved through a real-time SCADA system.
Follow the installation instructions in the .txt file once you unzip the ZIP file.

I swapped out a lightning damaged Goowe for a working, used one a few weeks ago. I had to get support to change the "owner"/ installer of the used one so the new owner could access it.
1 phone call and it was done! I was rather surprised.
They're reliable inverters, mine is 5 this year, no issues,never skipped a beat. I'm hoping another 5 yrs to go.

Goodwe records some events that are of some use, but there are not many. These can be consulted in the PV Master application as you already know and with a descriptive text. In this system that I make available to the PowerPhorum community, the option * Error / event log * shows the GOODWE events registered in PV Master, whose code I have been able to associate with a description in red letters on a white background and with the In order for this to have a greater sense and utility, I have added to this register the fundamental parameters of Operation at the time of the Device Error, such as Temperature, Apparent Power (workload), Effective, Voltages, Loads, Batteries, etc.
The rest of the Events appear with the name "System", of these there is a group in black letters and a red background that are the Reset and Trip events, because when Goodwe is reset it does not leave any record. To partially solve this, the parameters that I show in these cases are the live values taken "1 (one) sample before the event", that is, if the update of the live data you want to set it to, for example, 1000 milliseconds and The this system finds that Goodwe rebooted at 10:25:30, for example, in the Event Log you will see the live data logged up to 10:25:29.
To be more accurate than what the Goodwe readings give, if you have higher precision instruments than the device sensors, for example with external AC meters like the Eastron SDM series,Carlo Gavazzi, etc., or for batteries using a multimeter or with a Victron BMB600 or BMV702 connected between the batteries and the Inverter, in the OPTION "PARAMETERS" the AC Voltage values can be corrected and, on the other hand, Current or DC Voltages in the state of charge or discharge of the batteries in +/- to the hundredth of a volt or ampere. In this case, in the "LIVE DATA" section of the left panel, the parameter with the [c] indication will appear. If you accept the direct Goodwe values without any correction, just leave the values at "0", I have also added the Goodwe "Self-Consumption" Value for better precision in energy calculations. My device draws between 60 and 66 watts, which is more than the manufacturer reports. You can adjust other values for greater precision that are self-explanatory.
They will also have an idea of the actual maximum daily PV voltages and amps under load conditions (V imp and A imp) of each string, which can guide us to make modifications to our strings by pushing a little further towards the Goodwe limit in a more safe.
The maximum daily values of some parameters appear on the main screen of the scheme. I emphasize that to update a maximum value, internally I consider it only if 2 (two) consecutive samples are higher than the previous one, this in order to avoid peaks due to AC harmonics and / or other electrical disturbances with very instantaneous peaks.

Your comments and suggestions welcome!

For anybody else wondering about the different IMP ratings, here's the "official" reply from Goodwe:
So, unlike Sunsynk where a firmware upgrade seemingly bumped up the Max input current, this Goodwe came out with an "upgraded hardware" version down the line...

I present this program that I share with you in its VERSION 2.0. It is only for Goodwe Series "ES", that is, for GW3648D-ES and GW5048D-ES.

It has been developed solely for academic and hobby purposes, without any commercial objective.
With reference to Version 1.0 of the download area of the forum, beyond the correction of errors, small aesthetic changes, elimination of erroneous information from Goodwe itself (e_day and e_total), the self-discovery of the Power Inverter within the LAN network and adding battery self-defining parameters, I found it interesting to focus on one of Goodwe's weak points, which is the error log.

Like most users who have experienced them and beyond the degree of technical knowledge, I would have liked Goodwe some more information when a "trip" occurs due to different circumstances during the use of batteries, normal operation or provoked with reference to The Working Load and Maximum Powers allowed, either in essential or non-essential loads or in both.

The operating parameters in the event of an error, the SEMS PORTAL shows them with 1 (minute) between data, a true eternity, this is of little use and the resulting query is frustrating, generally.

None of the above schemes. The correct one (in a simplified way) is this:
 

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.

I show an screen copy and a short screen video of software in development, the video is in .flv format. The tests so far have been satisfactory.

Not sure what you mean by upgrade - I did install latest firmware in all batteries, UP5000 as master, and off it went....
At the peak I was running (in this order):
UP5000 master
US3000C
US3000C
US3000
US2000Plus
(Temp install for only a week, hence the "incorrect" single inverter power cable...two of the batteries have since gone to my parents;-)

@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 !

You see Abrax, I don't know why you don't have your BackUp loads connected, it's the most important thing and the "Reason for Life" of a photovoltaic installation.
In the Error Log, this is a perfectly Normal Alarm because downstream of the home installation there could be a short circuit or a ground discharge that would trigger the protections of the Essential Loads Board and here it shows you the time it occurs. If it appears at the beginning of its execution, it warns you of a situation that is not normal and desirable
In reference to the Program Error that appears in the window that you show, it is correct, it appears in the event that you want to see the Hourly or Daily graphs and it is a BUG that appears for your particular installation since a situation was never contemplated in the program in which there is never consumption for Essential Loads. The program detects other data, but when the historical values of the essential loads (Back Up) are = 0, a failure situation occurs. Thanks for reporting it. I will correct this in the next review.
