WannabeSolarSparky

Just an update just received. He has recovered in such a way that he is out of ICU and in the high care ward. He looks better and can eat without help. Still awaiting results of the latest blood tests. Great to see he is on the recovery path. 🙏

Just a update. He went through a Pulmonary Thromboendarterectomy. He got some of his colour back but still in ICU. He is now off from ECMO but still on high flow oxygen.
We will keep him in our thoughts. 🙏🙏

Will share as soon as his wife gives me an update. They are stil waiting for news at the hospital.

Any BMS will protect the cells that is the primary function. Should you use voltage control or communication to the inverter the BMS cell protection is always active. So the cells would never see 3.7v the BMS will go into Ovp and shut the battery down. If voltage control is preferred just ensure the inverter is set with Oem battery specifications. @Antonio de Sa i agree with your battery voltage settings 3.5v is in die upper knee of the lfp curve not much capacity beyond that voltage so no need to stress the cell by charging to 3.65v. Good recipe for longevity.

@Scorp007 @frivan
To me it makes no sense charging the batteries to full cell voltage all the time.
Why stress the battery for just a couple of AH.
My battery is rated 56 V so individual cell should be charged to 3.5 V.
That is exactly what I do.
And the cells get to equalizing value.
See dashboards.

You can only see the aggregate current voltage and soc supplied by the master bms to the inverter.
This is what I would have done in your situation. Take the system down ac off pv off inverter off all 4 batteries off Disconnect the battery pos and negative from the master to the slaves. Leave master battery Can connected to inverter and remove the daisy chain link between the batteries. Power up with 1 battery charge to 100% Soc. Then connect the next battery until you have all 4 batteries charged individually to 100% Soc. Take the system down again and reconnect all 4 batteries. Power up and go to Li page on inverter and check if loaded parameters match battery specs. Check if aggregate Soc is 100%.

@frivan Will you follow your advice/suggestion above should it be your or your clients installation i don't think so. Rather give sound technical advice on this forum than " maak n plan" suggestions that puts equipment and property in jeopardy after all it is a bit of precision science.

Interesting discussion about the "Rules"

I have always maintained that if you are not planning to sell back to eskom/munic, there is no need to register. what happens in your property is your business, no one else' s.

Best is to look at the code editor.
Scroll down to the entities section:
Mine looks like this:

Just an update. @TaliaB has been discharged. He will take a well deserved break and relax with family on a farm for a few weeks. We wish him a superb few weeks. 🙏🙏🙏

There, I fixed it for you!😄
Glad you are feeling better.

Morning guys and ladies on the forum. I am feeling much better this morning due to the fact that I am in the medical ward instead of Icu or high care. I just want to take a moment to thank each and everyone for the well wishes and especially @Scorp007 my friend that passed the message on. It is very scary when it happens, can't breath and your heart start racing and you are overcome with anxiety, it goes through your mind is it a heart attack but I thought when it happened it felt like a blood clot same symptom as in Mauritius until I became unconscious. Later semi conscious with all these pipes and monitors. The physician and pulmanologist want to change my blood thinning regime from Xarelto to Warfarin.
Again thanks to all for your support.
God bless

Update from @TaliaB is great news. The blood clot got dissolved a lot quicker than in Mauritius by administering via a drip. He is currently in the high care ward and if all goes well tonight he will be moved to a general ward tomorrow. 🙏🙏🙏

Stick with reputable known good suppliers.

https://www.diygeek.co.za My 2x Narada batteries and and 1st growatt spf5000es and Sunsynk 5k inverter came from DIYGEEK running more than 5 years now with zero issues
https://segensolar.co.za Need an installer account to buy, some bargains but mostly a bit pricey
https://www.solarwaysuppliers.co.za I buy my panels and mounting systems from them, best prices online open to public
https://acdc.co.za Expensive, but can go there in emergency if desperate for something.
https://www.liteglo.co.za Electrical supplies online - nationwide delivery quick and their prices are really good, they based in JHB and I am in Cpt often get supplies from them cheaper than suppliers in cape town even after adding their courier fees.

That kind of sucks. So if you change anything on the solar installation you have to register again?
I got my solar in Feb last year. I have saved about 20k in my bill to date. I have paid off my GEL battery bank (11k for the 10 batteries) and my inverter (3.3k I paid for it). I am already way on my way to paying off the panels and accessories used. It was a self install so the labor I saved on.
This year, being off-grid without the fixed charges, I will save about 40k rand. My entire system with the solar geyser conversion was 78k. So by April next year I would have paid off my entire system.
A 12kW inverter now (Axpert clone) is about 9 to 10k) from Ecco. I will wait for my inverter to die and get one of those. Mine has run for a year now (also a clone from MUST) and has been perfect. Even if it packs up in 3 years, it has paid for itself multiple times over. So I wont be buying the more expensive brands as I dont think a 12kW Sunsynk for example which costs 30 to 40k will last 3 to 4 times longer.
So if one is willing, they can get a good deal on a 8kW plus inverter without breaking the bank.

Sadly a Sinogy victim here.
Reporting is very hard on google where they are active. On facebook at least people indicate Sinogy is a scam but on google they seemed ok, same as instagram. Am not on facebook, only checked after the guy went silent. However guys, please file a police case each time otherwise the guy keeps getting on. I see some comments on this forum that Sinogy installed for them but I suspect those guys are accomplices. They have also suddenly started selling EV chargers, same page and all.

Morning members and friends. It is with sadness that I have to inform you that @TaliaB had another big blood clot in his right lung. He is in the Netcare Christian Barnard Memorial hospital ICU. Let's us be with him in prayers and thoughts
As and when news is received I will share it here
🙏🙏🙏🙏

Surprisingly even with all the rain in December production was pretty good. Additional 6 panels were installed 19 September, 3rd battery was done 9 October. New loads from 3 November is pool pump (8hrs a day) and heat pump (5hrs a day).

I hope and trust that you will all have a great prosperous and sunny 2026 😀

After quite a few years running solar, my system is finally getting to the point where everything is running optimally.
Eskom only got R115 from me in December and in my books that is almost a big win :)

This year I have planned and budgeted to add another 10 solar panels to get ready for winter and to add my 4th JK powered battery to the system.
Winter 2025 showed me that I am way short of charging power and ended up where I had to give Eskom R400+ for 2 months (June/July) to top up my batteries.
I have north facing roof space to add the 8 new panels, so this should hopefully be enough to keep the batteries topped up nicely through June/July.
The added bonus of the new additions will be when Eskom start implementing fixed fees, I should then be able to disconnect and go fully off-grid.
