NMBM wants to install a “Tjommie” in my house…

Pretty common from what I’ve seen on estates with solar and BESS systems.

I can see the benefits for munis doing it also.

I wouldn’t fret over it personally. We are already getting messages about the grid being constrained our side.

This would help.

In other words, you will have cold water all day every day because it’s more "advanced".
Not really. I have watched these things work live. There are times where everything is loading the network, they switch off the geysers and non essentials until the load evens out and then bring it online again.

People must pick. Trips due to overload or you have power but your geyser is off for a little while.

Espwcoally useful when the neighbourhood is full of solar installs. The network was not designed to handle hundred of inverters charging batteries and heating geysers etc.

Let alone EV chargers on top of that. This is where I disagree with most guys on here. You can’t have your solar etc done and then expect the grid to charge your batteries on demand while also feeding your geysers etc.

Solar really effs up the grid. I didn’t believe it until I actually sat and watched historical data for an estate. The peaks just rise very quickly and suddenly when it’s cloudy and stuff.

In the specific place I was they had already installed these geyser controllers to combat that problem.

Okay Eskom defender. Why would you heat geysers and charge batteries at the same time? Those people deserve to be cut off for not connecting geyser to inverter.

I thought you said the network is designed to handle all the houses loads. Each house has 60A. That is 13.8kW. That is more than charging a battery and geyser.
