I like it when people with actual knowledge share it. Much better than the cesspool in other parts of the internets.But electrical stuff, its my trade, did it before I changed careers to IT.
I don't have a permit anymore to alter electrical installations and/or issue CoC, as I haven't done that kind of work in yonks.
What I do know for a fact is:
1. Eskom lies, and lies a lot
2. My own systems work, and they work well, the batteries are dying due to age
3. I complain because this is short of treason what is being done to my country of birth
Mine has not fallen below 49.8 Hz during the last two days, except for the two periods where we had loadshedding (where it went to 0 ).Eskom (and other sources) told me that mains frequency is an indication of load, the further it slips below 50Hz is an indication of system constraint. You can buy relays that will disconnect load when the frequency slips.
Ripple (geyser control relays) the electronic ones are designed to disconnect the load if the frequency goes below 48Hz
My power comes from Koeberg, so a low mains frequency tells me that the unit that is operational, is running at ABSOLUTE MAX FULL LOAD
Yup that's what I was pointing out, the frequency in some areas can be low while it can be fine in other areas. You cannot indicate that there is an issue because yours is low. I used to think that low voltage was an indication, but sadly before load shedding kicked in mine was still sitting at 234.Mine has not fallen below 49.8 Hz during the last two days, except for the two periods where we had loadshedding.
So you might say Koebert is constrained but I'm not sure it indicates the national grid.
Guaranteed hence I will make the most of that day, and do as much work as I can. They will pull the same rabbit out as they have done in recent past when Ramatosspot has had the need to reprimand the comradesGuaranteed we'll have no blackouts on 1 November, 'Ek's dom' will pull a rabbit out of a hat!
You need 2 batteries for 24V.20amp Solar Charger (R2k)

Total R13k+ (Excluding install) and all your lights, alarm systems, and connectivity have an almost indefinite power supply during load shedding. With the automatic change over switch I don't even get off the couch. During the day you can run your laptops, TV and Freezer if needed. Keeping the lights on doesn't have to cost you an arm and a leg. I know this is not possible for everyone, but if you can, it makes life so much easier during load shedding.
This is just an example of the system I started on. I did have to replace all lights with LED's, but this was gradual and probably only added another R1k. We were already using a gas for cooking so that helped as well.
Add a larger Charge controller, and more batteries and life gets a little better, or just keep the lights on and add a parallel grid tie system (no batteries, and no feedback), and show the middle finger to Eskom.
Nope you might've been one of the lucky few, I know block 2 in Johannesburg didn't get hit, but somehow they generally do miss a few. Whereas block 11 has missed none and in fact get hit when it's not even load shedding.
