Where are you based? I recommend getting a professional 3rd party to check the entire system thoroughly. Wouldn't trust the installers know how given the south facing panels.

South facing panels is a waste in South Africa, won't get much production.

Another company to stay away from, despite them originally being legit : livestainable.co.za See Post in thread 'Experiences with livestainable.co.za' https://mybroadband.co.za/forum/threads/experiences-with-livestainable-co-za.1214305/post-34457298

This is a common issue, well known to Sunsynk /Deye, just that wifi board can be removed and taken in to Sunsynk over the counter and swapped for a replacement no problem. You could do it yourself actually. The entire inverter doesn't have to be removed. Rather do it within warranty and they'll replace free of charge

Bump still available

Will message you. Full monitoring details in home assistant available. Thanks

Installed August 2023 Timer setting was to discharge to around 40% daily. Which didn't happen daily probably as per the cycles being around 310. At 20% would be very few times when the municipal power was down for a while, with the inverter switching off the loads at 15% or 20%. The Sunsynk 16kwh inverter they were linked to has been sold already and the site was deleted, so the historical data is not available. Further diagnostics it could be extracted from the battery if need be.

For anyone wanting to run things locally on home assistant without the cloud, smartpad have quite a few options and their service is exceptional. https://store.smartpad.co.za/index.php/product/esphome-smart-controller-energy-monitoring/

There's no 16kw 3 phase. You should look at the 15kw or 20kw 3 phase

Have a look at the Deye SE-F16, 16kwh and around the same price

Try Disable mobile data so phone stays on the logger WiFi. If that's already done : Try these pages instead: http://10.10.10.1/config.html http://10.10.10.1/goform/config If no luck, hard reset by holding down RESET button for 10–15s while connected to inverter, and try again. Lastly, try another Sunsynk logger in your inverter and see if the issue persists, these loggers do fail at times, RMA it

Have bought multiple units from these guys https://store.smartpad.co.za/index.php/product/cbi-tasmota-astute-smart-controller/

Doesn't seem like an online double conversion ups

If you willing to pay probably more than double, you can look into APC or Eaton brands , who will sell additional battery expander units as well (Rackmount Extended Battery). Alternatively your 'make a plan' with your own batteries will probably work as well, but have no experience on that.

On the 1kva (few years old model) there's no SA plug. I think it's got 4 or 6x IEC

'Winner Pro' ups, branded RCT, Mecer etc, are manufactured by Voltronics. That's not a bad thing, it's good to know the manufacturers are on that level https://voltronicpower.com/en-US/Product/Detail/Winner-Pro-1KVA-10KVA

I have a 1kva equivalent and going strong years later. They are all very similar, voltronics rebrands from the looks of it. Note the dimensions of the 3kva, it's quite deep, won't fit in a wall mounted network rack.

Software, if you talking about the app and Web application, yes that's Sunsynk developed. No way Deye learnt any firmware features from Sunsynk. Lol. I've had the Deye support team even load a Sunsynk firmware for me onto a Deye inverter to test doing a firmware update with a Sunsynk dongle (where the deye dongle wasn't working). Go figure.

The firmware running the inverter is almost the same between Deye and Sunsynk, just GUI is different. They are engineered by Deye. Deye makes the Sunsynk firmware and can do updates etc from their side as well, for Sunsynk units too. Yes the app and website differ. The GUI is slightly different. But the Deye engineers are handling all that. Sunsynk is just a middle man to put it bluntly. There may be variations between firmware versions that can cause a difference as well, as mentioned above.

While Solis doing a swap out for a new unit is commendable where applicable, for the client with no insurance, Deye makes much more sense. I've seen lightning surges knock out the comms boards etc on Deye units, even the main board, screen etc, they repair them all under warranty without hassle, minimal questions asked. And the units work perfectly years later, with the 10 year warranty still in place (if using Deye batteries). So whilst there may be a tiny percentage of repairs that need to be sent back again, I don't think that should be the basis for not purchasing Deye. The majority of the repairs (huge quantities) are done well. They don't do board level repairs, the Parts are replaced and inverters tested thoroughly. And I've also heard of furious Solis clients when Solis tell them there's nothing they can do for them. They won't replace nor repair. The client is stuck. So for someone with insurance, Solis is a solid choice. Otherwise not. Also, yes the SPDs are obviously required and we are talking about installs where despite the SPDs, there was still damage.
