This is the first step, if someone plugs something in the kitchen and it doesn't work it will trigger something, if the person proceeds to make other plans to plug whatever at some other location you know they are deliberately sabotaging your infrastructure, that's when you take firm and decisive measures.

We have one
. In the process of updating info on it now 2Kva 1600w Mecer IVR Alternative Inverter With Adjustable Voltage Parameters
Because of the amount of come backs I have been getting on the Mecer inverters which lead me to look for an alternative and I stumbled across this gem and with voltage settings being adjustable being an absolute bonus. There are 2 variations that I have received in stock. One that comes with a...

Split your DB up. Your installer should have advised you on what to do. Mine installed some dedicated plug points in the kitchen that runs off the inverter. otherwise the whole kitchen breaker, stove and oven breaker are running off eskom and everything else runs off my inverter

@Iamn0tageek I would get a Voltronic (aka Axpert, Mecer, Kodak, RCT etc) 3kVA rack mount at about R8-9k with a PylonTech/Dyness 2.4kWh lithium at about R17k
I would not waste your time with gel or lead acid, with our duty cycles here it costs you more than lithium over the lifespan. The 2.4kWh should carry you through 4 hours and because the solution is modular you can expand it if needed. This is better value than the ecoflow system. And because both are rack mount they can go in your network cabinet or under a desk.
Quite a few places stock these, the 3kVA rack mount is a bit harder to find than the 5kVA rack mount. Last place I saw that had stock was Sustainable Energy Solutions.

Hi Iamn0tageek
Guys, so having gone through this exact same delemma as you I can confidently say out of experience now get yourself an inverter system with batteries that uses LifePo4 technology. They are far superior to anything else and will last you for years to come and will spare you a lot of headache.
As far your question. I have a pc with basicly exactly the same spec as you, I just have a GTX1060 but with 2 powered monitor speakers, 2 mechanical drives and 3 nvme drives. I bought myself a KOOLEnergy 1kw inverter with 1280wh capacity and 2000 cycles at 80% discharge. Now for those who don't know, wh is the capacity in watt you can draw over time. So in this case you can use 1280w in 1 hour or 300w over 4 hours. I load tested my setup and managed to created MAX 210w of load which translates to 5hours of play time. You should be able to see from the pictures I'm running Tomb Raider benchmark and you can see the draw on the display of the inverter.
If you are interested I can get the same inverter for you at R12 000incl VAT excl shipping. There is also larger 1.5kw and 2kw versions of the same system

I can completely agree. My brother-in-law went with this same setup basicly. He has a Deye 5kw inverter and 4.8kw battery pack. The inverter has to 2 load outputs, 1 priority of backup load and the load coming from the DB. This inverter though is capable to push load back toward the DB on the same line and has a CT clamp installed on the main power supply line. He painstakingly seperated the dB splitting them with only some on the priority load.
The great thing about this is he can with the 6 panels he has still use solar during the day or even the battery while the grid is active to save power for non essential loads with it using the CT clamp to make sure power don't splill back to the grid but can also be used to track power sold back to the grid if Eskom makes that available in future. When loadshedding kicks in only essential loads has power or in the above mentioned case the specially installed plugs

Powering the ONT/router is easy. Ellies Mini Cube or similar would do it, for best results use a dedicated mini UPS per device. For gaming buy a Nintendo Switch or game on a tablet/mobile.
If you want to power 500+ watts you'll need one of these expensive Bluetti/Jackery/Ecoflow batteries for about R25K. If the cost of a new RTX 4090 is worth it to you in batteries, get that.
Speak to them? Maybe put stickers on the oven, kettle, toaster, until it becomes habitual? How do you get people not to open the patio door or go outside because the perimeter alarm is on? People learn.

You can. But that’s just a poor oversight from your installer who should have done something from the beginning.
And split up your loads into essential and non essential. Where the non essential loads turn off during loadshedding
Can you send/post info? I am looking to get another backup to my current solution and wouldn't mind more details.
