Seems like this could be a good case for OUTA to look at 🙂

Seems like COCT is going full-on Aussie nanny state mode...🤣

If the battery BMS is a proper one it should stop accepting charge if there is a risk of overcharging.

4 Bedroom home I would say budget in the R100k - R120k region at least. Have u got more info to share such as geyser type, stove type etc ?

Not a Deye expert at all. But you can achieve this automation with Solar Assistant.

TBH - my experience with Ecco is that it is a cheap and nasty brand mostly found at the various China Malls and Pakistani/Indian cellphone accessory shops here in JHB. I personally wouldn't recommend it to anyone I like 🙂 - I sincerely doubt whether the 5 year warranty is going to be worth the paper its wrtitten on. What is the value of a warranty if there is no one in the country to actually act on a warranty claim. Leroy Merlin might list it on their website but I have found that they also have a market place program like Takealot where third parties can sell their goods online through their website. Leroy Merlin/Takealot only acts as a channel to sell through.

Saw this coming ages ago...the people that actually pay for their electricity, a lot of them will have the financial means or have access to credit to go solar thereby massively reducing the only consumer revenue line that ESKOM has. Business has also gone this route in a big way so I wonder if you add that into the equasion how the figure of installed solar will look?

I don't know of a domestic inverter that supports SNMP. SolarAssistant supports MQTT which allows you to pull telemtry from the inverter and display it in something like Home Assistant if the graphs you receive in SolarAssistant isnt enough for you. www.solar-asstant.io

Item: Sungod 48v LiFiPO4 4.8kwh Wall Mount Battery Age: 6 months Price: R18 000 onco. Payment Method Accepted: EFT/CASH Warranty: No Warranty Holder: No Packaging: No Condition: As New - probably less than 50 cycles Location: Roodepoort Reason: My mate bought the wrong battery for his system Shipping: No Collection: Yes Link: https://www.proximatesolar.co.za/product/4-8kwh-sun-god-wall-mount-48v-lithium-battery/ Selling on behalf of a mate of mine - he bought two Sungod batteries - however he bought the 48v and the 51.2v not knowing that they had to be the same voltage when connected to his inverter. He paid R23000 for the battery in February 2023 and is just looking to get some cash back to buy another 51.2v.

So I am very uninformed when it comes to plumbing LOL 🙂 in the auto scenario - how does the water consumption end only use the mains supply when it is there - how does the water not flow from the tank automatically? Sorry if the question is unclear - not sure how to explain what I am asking 🙂 Is it a function of the pumpthat detects it needs to pump when the mains supply is down? I understand the second scenario 🙂

Thanks for the replies all 🙂

Hi all I am in the process of installing a JoJo tank for water backup in the case of municpal outages. Just wanted to check though - under normal circumstances where there is muicipal supply, does a person run the house water from the tank all the time - ie. as you use water the tank refills itself via the float valve. Or is it a situation where you switch the water supply to the tank when the municipal feed is not there? Ie use it for backup ONLY? I see JoJo reckons you should wash the car or fill the pool everytwo weeks or so with the water in the tank in order to refill with clean water again. I assume this is for where it is used as backup only, as in my first scenario above you would be refilling it continiously. I am installing an under counter water purification system in the kitchen. I also havea fridge connected to water supply with a filter. So enough to sort out the odd glass of water. We never drink out of the taps in the bathrooms. Specs: 5000L tank with a 0.75w pump.

You need to set up a port forward to the static internal IP on your router.

Specs look similar on the surface - one is rack mount the other wall mounted - Same manufacturer so good chance they will work - but cannot give a definitive yes.

This morning:

So sorry all - there are in fact only 8 panels installed...my bad - so I think the Voc should be fine. @Talia - SPD's are installed

HI all My mate has 10 x 550 Jinko Bificial Panels hooked up in series to a Kodak OG-10. Inverter specs are: Panels are: We got this strange solar behaviour this morning in bright sunshine - there may be a bot of shading in the morning from some trees as well as a small chimney - could this be the issue? Any other ideas as to what could be the cause perhaps? There was load on th einverter from the house and the batteries were charging.

Hi all I have an electric hob installed in my kitchen at the moment. Unfortunately when they fitted it years ago the granote cut-out was made "nommer pas" so now that I want to go gas I cannot find a hob that will fit - they are all about 10mm larger. Can the existing piece of granite be cut/grinded slightly large to fit the new hob? If so how is this done? Cheers Douw

Thank you for the comprehensive answer Justin. What you describe is pretty much how I set up the inverter for him and what he is experiencing. But ja as you say in the long run it will give problems...

Original post link in opening post explains the issues with his "supplier". Anyway it's not as simple as it sounds it seems to remove the cell. I guess schoolfees for him unfortunately.

I am starting to lean very much in the direction of suggesting we just do this for him. I doubt he is going to have any warranty any based on the fact that the guy who supplied is a schyster anyway. Is it then simply a case of disconnecting cell 16 and removing it? The BMS's look identical if the display is anything to go by

Can confirm that Dyness BX51100 works with the Mecer Axpert units over RS-485

No to clarify: Both are LiFePo4 chemistry 1 x 51.2v (16 cell) 1 x 48v (15 cell) Its just that the 48 volt has the same BMS but shows cell 16 as 0.0v - so it only has 15 cells.

I have also done similar automations. WELL DONE for making a video to help others...I am too lazy
