Can someone explain to me pls?

Think we need to move offices to Cape Town... this can't continue man. And they are only ****ing ober the middle class more. Over 40% in rates and taxes per litre of fuel. 40% of our salaries going to tax and then on every thing we buy 15%. So of my salary I probably only get the benefit of around 40% if not less... ffs

Running a genny is stupid. You will pay forever.
All that money you are spending now could be going to solar - then they will be paying you.

You need both.
My sister and brother in law have been running out of power in ekurhuleni despite having quite a large ESS solar system. A cloudy week plus stage 6 loadshedding means not enough time to recharge their batteries properly... A generator would have saved them a few dark evenings and cold showers. That being said he was a bit silly not to convert to gas hot water as well.

No that's down to not managing properly again. I don't have a generator at the moment and I went through the stage 6 without batteries running low, also had days of no sun.
Watch the weather, watch the schedules and plan accordingily. Though having no power for a few days might cause me some headaches.

That's nonsense.

I've said this for ages. This CEO makes illogical decisions that just don't make sense.

Residential electricity use is around 22% of ALL consumption but De Ruyter loadshedding is more at night, on weekends, and in holidays

Total pump storage is only 6%. Therefor it only uses 6% or less to recharge all of them
View attachment 1452217

Planned maintenance means exactly that...it is planned...not executed.

Planned maintenance is simply a way to create the shortfall to execute loadshedding. And that is why the same units break over and over

Its a combination of things

  • Pumped storage is one
  • During that time all solar goes offline so will increase load
  • Some businesses are running after hours to catch up what they missed during the daylight loadshedding hours
  • The cost of burning diesel all day means that they need to take a break at night.
  • Residential usage peaks

Its basically the time where everything overlaps and catches up with its self.

Probably living their best life and running all the things.

Ye - combo is what makes it work. Stage 6 is the exception though.

I mean sure, I've seen people moan their batteries don't last and it's getting worse but it's like guys, manage them better. You know you're going into a 4 hour stint, ensure you've got the resources to handle it.

There are valid scenarios where you need both. TBF he did say running out of power, and not normal stage 6. A 4 day outage combined with a week of rain would leave most solar users a bit hot under the collar. A gennie will at least let you charge your batteries...

Yeah I did say that, a few days would cause me headaches, but the normal stage 6 was easily manageable.

I have heard some horror stories with regards to Solar systems, even though I think you are 100% correct in the long run.

Even though you don't have a constant expense on the Solar like with a generator, these batteries cost a fortune and needs replacing from time to time. I think a hybrid type of solution would probably suit me best. But just haven't had the time to look into it yet.
 
Mike Hoxbig said:
Look here Mr Trying To Sound Smart On The Interwebs, increased maintenance is the reason given for load shedding and why his hands are tied. If it weren't for so much maintenance then the units would be run too hard and eventually break right? This is what we've been told.
Click to expand...

No maintenance for 20 years is the reason for the load shedding. That has led to increased maintenance to play catchup for the lost 20 years. However, it will take over 20 years to catch it up due to a complete shut down being impossible as well as ageing of plant and obsolescence. Thus it will never be fixed. If you could do the logistic engineering calculations, you would realise this. The general public can't do those, therefore they can never realise the complexity.

Surely it shouldn't be too hard to paint the full picture and let people decide for themselves, instead of painting the picture you'd like them to see.

Do you believe that people that are incapable of repairing a car or egg beater are capable of engineering maintenance insight?

Mike Hoxbig said:
Who knows, it might shed some light into the quality of maintenance being done. Heck make the maintenance schedule and details public. The more information about what's going on, the better. It's not like they have to worry about losing a competitive edge.

Do you believe the general public is capable of understanding and working out the reasons for the periodicity in planned maintenance?

Mike Hoxbig said:
PS I have an honours in applied maths. Which field of mathematics or engineering are you qualified in? Since me and the general public are clueless in these fields, and you are not...

Which means you would be able to work out the periodicity of planned maintenance had you studied logistics engineering. My post grad qualification.

The batteries should last up to 10 years and if they are lithium they only lose a certain % of their usability, so after 10 years it would be 80% usable still.
Also those horror stories are more then likely people who didn't plan, or have been using it as if it's an endless source, or didn't check what they actually need.
During the day generally don't run on batteries, it's the sun, at night run on batteries, till sun comes up. Sure cloudy days I may need to pull from Eskom + geyser and stove still pull from eskom as well.

And which undergrad qualification led to this postgrad qualification?

Actually nvm, I don't have time for a back and forth with you. You win, your ePenis is bigger. I succumb to the superiority of the logistics engineer...

From a cost POV I'm not going to bother with batteries. I have lamps and a gas stove. I'll get as much solar as I can afford and have power during the day, excess power can feed back to the grid and earn credits. If wind becomes a viable option then Ill invest in that as well (for now it looks like its not)
Every cent put into Batteries is money that could go into panels

Except if you're in South Africa, the batteries are there so you have power all the time. Doesn't help if you've got panels for the day but at night you sit in the dark.
Also if you have batteries you could then rather pump excess into the grid once those are installed.

That's what I do, so I agree that it depends on how a system was planned. But I still have and maintain my genny for black starts. Having panels filled with sunshine doesn't help to start the inverter's MPPT controllers, it still needs a few watts of power.

Don't bank on earning credits for feedin. IF your meter runs backwards - this will end as soon as the municipality decides to roll out new meters. The feed-in tariffs are shyte. You want batteries, I promise.
 
Yeah I need to find a solar solution, have the inverter and a 200ah lithium battery which has been working fine (even when down for 18 hours). But Im renting to no panels on the roof , and being at the coast, there is all the cloudy days and none of the damn houses are build north facing. So I can't go with a large number of panels, have to be mobile . Only need it to help feed the battery when Eskom is down for a long time.
