Another option that is worth a look is Openhabian - it is also well supported. 
I whent full automation about three years ago and sofar Openhab has treated me well. 
This is what my layout looks like :

Massive thank you to @LoodPyp for helping me out with some of his old working kit! Successfully installed and working keeping some light on at my elderly parents' home!!

Hi. I have 2 mercer 200ah 12v Lithium batteries for sales. Both were swopped out by Mustek two weeks ago so they are brand new. The warranty is still valid until June 2023.
I am looking for 13k for both - https://www.takealot.com/mecer-lifepo4-12-8v-200ah-lithium-battery-sol-b-l-m200/PLID91577930
 

Mmm I want this

Hi 
 
We are happy to give away a bundle pack which will include:
1x Sonoff Loadshedder or (if you don’t have a Invertor we can swap for L3 PRO)
1x Sonoff POWR320 Elite with display (will give you the ability to turn off the geyser)
1x Sonoff RGB Bulb which you can scene control to change colours with the Loadshedder which lets you know there load shedding
1x Sonoff 2CH Light Switch T0US2C (Introduction to smart lighting and scene control)  
1x Sonoff Basic (for any other device you would like to use it on)
 
Thank you for all you knowledge sharing on this forum and we will do these give- ways as often as we can.

Hi Jason
 
I completley agree, give me 30 minutes and I will come up with a few products. I will try and do something nice a easy.

Hi Guys so here is another GIVE AWAY!
 
We are busy with a test and review of the GREENRICH U-P5000 1.5C 4.96 kWh Lithium Battery 
 
Yes we will be giving one away to one lucky Power Forum Member in a Lucky Draw 
 
I will post details on how to qualify for this GIVE AWAY soon watch this space!

So some educational information about these batteries 
 
As you all know Greenrich batteries have been in the market for some time now and so far we have had mostly positive feedback from installer and end users alike.
 
What makes the battery desirable is the 1.5C Rating this means the battery can discharge at 1.5 times its capacity rating.
 
Why would that be so great?
 
Here is why if you have a 8KW inverter discharge the battery at 8kWh then this 4.96 kWh battery will be able to absorb a charge rate between 0.5C & 0.75C and a discharge rate at 1.5C without tripping the benefits of that is that when you start of on your solar journey you don't have to break the bank with just one 4.96 kWh Greenrich Battery because your 8KW inverter will struggle to reach the discharge rates of the battery. 
 
The 4.96 kWh is also inter compatible with the 3.686 kWh Greenrich Lithium if you require to expand to additional capacity.
 
This Lithium battery is the only Lithium battery in the market that offers true 1.5C discharge ratings. With 1.5C discharge rates, the Greenrich lithium battery has a much higher power output compared to other 0.5C or 1C lithium batteries. 
 
The cell technology in the battery is LFP cylindrical high density cells which can do up to 2C however for longevity the BMS limits the discharge  to 1.5C and charger rates to 0.5C continuous and boost charge rate for 5 minutes to 0.75C

DATA SHEET

This is what one could have expected today. The peak was lower than the last few weeks. This is from a 1620W array running full tilt. I guess the weather was about the same in Mpumalanga than in Gauteng.

 

Using 10 panels in series at a temp of 5 degrees which is a given in Secunda the Voc could go up to 504.96V and blow the MPPT. 9 is a saver bet.

Welcome! The members will be happy to assist you. Thanks all.

Hi I An3s from MP Secunda new to this and the more I read and do reaching the more overwhelming it is getting.
I started collecting parts for building a system  
2x 420w canadiansolar panels 
2x200ah batterys 
Kodak og 3.25 vmiii 
Had the inverter installed last week
The idea was to install to install 2 pannels that I already bought but the inverter mppt startup voltage is 150v and my 2 panels wil only give me 96v, I was planning on adding panels monthly after everything was up and running, question is wil the syst work or should I get 1 more panel first.
Was planning on getting pv combiner box end of the month and have it installed withe the 2 panels and then just add panels 
Sorry if everything sounds confusing thats just part of my ADHD
 

Just pretend not to see all the holes in the wall the domestic worker had nails and all sorts of things on the walls years ago,but this is how far my system is at the moment
