Something like this:Only the Neutral.

Is there any space on the side of the house just to put 1-2-3-4-5-6 and 7-8-9-10-11-12 onto a pure East-West setup.
Considering that it's a total of 5.5kW of panels on a 5kW inverter, you're over-panelled anyway.
Otherwise, what about just adding one panel to each East and West roof, and using the two north-facing panels with a new DC water-heating element. Geyserwise or similar?

I might have a US3000C battery for sale in the next week or so for R18k. its 6 months old. 

A closed mouth never catches any pies! 🙂

Does it talk to Goodwe?

Just a simple question, maybe I missed it.
What is the guarantee period and the guaranteed number of cycles ?
Also need to know the max depth of discharge for the number of cycles ?

Great app @Cef.

I'll add a vote to being able to select between multiple ES inverters. I have two ES inverters and one 5000SBP which the app picks up occasionally and displays (with some errors). Being able to select an inverter / IP address would be a helpful enhancement to select a specific ES inverter (and ignore the SBP).
Also, I'm not able to exit the app. I need to kill it with Task Manager. Did I miss something in the install that prevents the close 'X' from working?

Biggest insight for me was how low the voltage is on short (<10 panel) strings and how long in the early morning and late afternoon the voltage sits below the MPPT minimum of 150V.

Thanks for all that you've done with the app and engaging with the community.

Cheers,
David

@curto,
😆😆😃, I get your point .
But you insist on a design philosophy that Python programmers and yours fans can see very well, but I am from another era and my philosophy is different.
If I am going to make a program just for me, obviously I would do it in the simplest way that is the solution you propose and what I did in the first version: static address and immediate connection, expanding that simple concept in addition to knowing all the IP addresses to decide which one to connect with.
But my intention is to share what I do with anyone who thinks they like and serve them like me, even if they don't have much notion of what a static or dynamic IP is delivered by a DHCP from a router, simply because an installer didn't just install your entire solar system and left your equipment set up on your LAN and you haven't taken any computer science courses, you don't understand or care.
I do not live from programming, it is my hobby and in that line I look for 4 objectives:
1.) That the system provide me information in real time with the lowest refresh rate (polling rate) that Goodwe's hardware inverter technology allows, in this case, so that the energy sum equations have the highest possible precision and having the data available to be able to use the full power of a PC to add many more functionalities.
2.) Use a platform that allows me to save my data locally, not depend on the web cloud and is reasonably protected against read / write failures.
3.) That it is as visually attractive as possible within my own limitations of graphic design concepts, having a Micro PC and a Monitor next to the Inverter and that my whole family understand what is happening and show it to my friends and people who want to get into Solar Energy, without being so aware of the additional consumption of  10 Wh more, since for an industrial micro PC it is not much greater than a Blackberry PHI 4.
4.) That it is intuitive, easy to use and therefore does not require more than a minimum of knowledge to install the program as anyone does and that it works for anyone, such as PVMaster / EzManager.
His intervention was useful when he told me that he has 3 (three) inverters connected to his LAN and that the PVMaster makes a kind of internal list for 10 seconds. I did not know that.
To avoid what the PVMaster does wrong, we just need to improve the search algorithm.
When I have time I will continue with this topic to automate the discovery of all Goodwe inverters automatically.
Regards.

OK... so I'm maintaining a watching brief on this one. I've not even updated the software on my Goodwe 5048ES yet, and draw almost zero data from it.

This is a hurdle I have to overcome sometime in the future (after connecting up my 5th array of panels, and finishing off the drip irrigation system in my vegetable field, and the plumbing from my well to the main water tank, and, and, and...).

I'm hoping that some clever guy is going to set himself up as the Goodwe expert and I'll be able to hire him to come do all of that for me 😂

Thank you very much, that’ll get me on the right path. I used to be a hardware and software developer in a past life, but on the hardware side it was only low current stuff. Power electronics is a different animal altogether hehe. 
 
Only real issue at the moment for me is talking to my Goodwe inverter. There are ways to scrape the SEMS website, but it only gets updated every 5 minutes; I’m looking at ways to get much faster (thus More relevant) info off the inverter to drive something like this.
