Hi All
We have recently upgraded a system for a client and removed 2 x Dyness 48100
If anyone is interested

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. 🙏🙏

Plan looks solid - if you can get 18 panels then go for it - panels are the cheapest upgrade and if you can max those as far as possible then go for it - it will help you even on a cloudy day.Spend an extra R600 and get a geyser smart switch installed - heating is the biggest draw on batteries so timing it for the day will go a long way.

I've got a Dyness A48100 I might look at selling, as I want to increase capacity. Not sure of the cycles but installed August 2022. I'm in Randburg. Price is negotiable. PM me if interested.

I did my humble little solar install in August 2020. At the time I had around 980kWh credit on my prepaid meter, which for about 4 years I hardly ever used. Around 2 years later (circa 2022) City Power sent their "auditors" in to check the meter. They left with no findings.
Then came 2023, where they upgraded all the prepaid meters to "Smart Meters" in the HOA. When they came to mine, they said that they could not upgrade it, because there was over 500kWh on the meter and they were limited to transfer credits of 500kWh and under. So I was overlooked on that upgrade.
I then decided to use my credits, after all, I had paid for them and they were not doing me any good sitting in the meter. So every month I used a few kWh, and I started neglecting lifestyle changes that I had made back in 2020, like not roasting a small eisbein at midnight when I got the munchies.
The "auditors" came and went a few more times, and the prepaid meter's crypto key update was also duly performed in 2024. Fast forward to December 2025. I was going away for holidays, and my prepaid meter showed less than 1 unit left. I did not bother topping up because I would not be there, and my system doesn't need the grid, but I didn't budget for the inverter pushing some back to the grid, which it usually does when a big load stops, and which the meter counts as usage. Around 28 December I noticed that the grid had disconnected, and upon returning home on 2 January 2026, I tried to purchase electricity, but no go, I was advised to call City Power. When I called them, they were extremely unhelpful, telling me that I needed to come in to see them.
I drove over to City Power's offices, which was in disarray. As luck would have it, there was a big power outage, and they had no power, nor any backup, and the ETR was unavailable, so all visitors were told to come back another day. I insisted on seeing someone, but they said that all staff had gone home due to the power outage. I stuck to my guns, and told them that I would not be leaving. They eventually extracted a surly and most unpleasant Marxist drone The Borg from his office. He listened to my story, then disappeared back down the dark corridor. After 45m of waiting in the stuffy, unlit foyer, I went hunting for him using my cellphone flashlight. I found him sitting in his dingy, unlit office, staring into his laptop. He grunted at me, and motioned me to sit down. He asked me why I was not buying electricity from them. I repeated my story again to him. He then asked for my rates and taxes number, and proceeded to do checks on my CoJ bill. Finding nothing amiss there, he told me that he would not reinstate my meter until I paid him a R15,000.00 "fine" for not using electricity. I protested, and he scowled at me. I scowled back. Another round of argument, where he changed his story: It was now no longer a "fine", but the R15,000 had to be paid because that was what a smart meter would cost. Yet another round of argument. The situation was beyond bizarre, here I was arguing with The Borg about why I should not be "fined" for not using City Power electricity, whilst sitting in an unpowered, unlit, stuffy City Power office. Eventually he conceded that he would "raise the matter with a senior manager", who was on leave at that time, and get back to me.
Seeing that it was going nowhere, I resigned myself to my fate, went back to my 2020 lifestyle of frugality, and started pricing batteries. Needless to say, The Borg never bothered to come back to me, and I didn't bother begging him to either. I placed an order with Wimpie from The Powerforumstore, and soon my batteries arrived. I decommissioned my 3x US3000 Pylontechs and donated them to my brother, and installed my new 32kWh storage.
I am very happy, because not only have I defeated Marxism and The Borg, but I can now roast a leg of lamb and a few Eisbeins at midnight again. Bon Appetit!

Just another update 5 months later and so far the system is running well only had to use the grid a couple of times when raining for a couple of days.

Ive gone back and did the number properly - my previous estimates were optimistic to say the least
System installed December 2021
Solar generation since then - 25.9MWh
Solar generation savings - R72k (using Tshwane block charges)
Grid used - 11.5MWh
Grid cost - R29k
Battery discharge - 11.7MWh
System cost me 185k all in done in 3 tranches (battery and panel upgrades) of 90, 45 and 50k. So I will have "saved" 50% of my system cost by the end of this year.

For anybody interested, I went ahead and bought 2x Dyness Powerbricks. Thus far they seem to be working great. Obviously I can't access the detailed battery information in Solar-Assistant, BUT the Dyness app is very good to see that kind of detail. If I really want that, I can just log into the Dyness app and see detail that is about on par with 1what I used to be able to see in Solar-Assistant. I've attached some screen prints below.
On top of everything, it comes with a built-in fire extinguisher system that responds within 5s.
I replaced 6x 5.5kw batteries with 2 of these and while the total power is about 4kw less than before, I get more usable power out of these since it can discharge to 95%. I am planning to get another one in future though (which is part of the reason for the upgrade... out of wall space). Thus far I'm very happy with the upgrade, but will have to see if I still feel the same way 2 years down the line.

I'm currently running 2x5Kw Sunsynks with no issues. Manufacture dates of the inverters are over 1yr apart but they are on the same firmware and provide great functionality in parallel. It is true there is a bit more complexity but its also set and forget, You change the settings on one and they cascade to the other without you needing to do anything. Redundancy is key for me hence i got the 2x5 vs 1x8 / 10

Year 4 Update - running swimmingly

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
🙏🙏🙏🙏

I lied. I moved them all over yesterday.
All the automations and schedules are working so far. Any remaining problems are my PEBCAK.
SmartLife can control the CBI devices.

Thanks.

I tried again today and had a much easier time of it.

I first deleted the device from CBI, then deactivated the Google Home automation that used the device (this may not have been necessary, the device disappeared from Google Home as I removed it from CBI).

I said that CBI do what looks like a manual add in smart home, so I did as you suggested and added it by specifying the type of device rather than by just letting SmartLife scan.
I added it under the headings
Electrical
- Switch Module
-- Breaker (other)
Interestingly it was added with the name I'd given it in CBI and with the power usage history. A little bonus.
I've checked that I can manually turn the ASC on and off from within SmartLife. I've now deleted the Google Home automation and set up scheduling in SmartLife.

Now we wait and see. If the scheduling works then I am going to move the other devices over one by one and then I can control everything in SmartLife.
One difference is in the automations. In Google I had one that started at 16:00, turned an ASC on, waited 14 hours and 30 minutes and then turned it off again. In SmartLife you can put the waits into an automation, but they cannot exceed 5 hours. This is a difference, but not really that big a deal so far and thinking of the other automations I have set up.
So thanks @nk00li , you gave me the crucial piece of the puzzle.
If all this works then I start moving the other devices over.

Year 4 Update - running swimmingly

@Tag11 @Sidewinder @I84RiS
Took a couple of days, but the owner of NovaCraft passed on the question of the RS232 port on the Esener 16kWh battery
They then sent him a photo of the ports. Standard Pace BMS, including the RS232 port.
Also noticed a plastic pouch with Bluetooth and WiFi QR code attached. That would be a bonus too.

I asked him to communicate with Esener and request that they update their concise spec sheet accordingly if indeed this is the Esener 16kWh

I have 2 geysers.
Main is a Solar thermosiphon with electrical backup - installed in 2010.
The cottage is a is a regular 100l Kwikot (installed 2021).
I have timers on both that limit electricity from 10am - 15pm - I use the geysers as a "heat battery"
