Solar generation in rain/cloudy conditions

You sound like my polar opposite. Am lazy as **** and the reason for carnivore was so I didn't have to think about what to cook and frying a steak takes 5 mins. :ROFL:
Yup same, I did try the whole gym thing in my early 20s, did manage to get up and past being able to bench my weight. But then the buddy I went with moved overseas and the constant nagging to go to gym stopped.
So I stopped and got fat instead
 
Another day like yesterday and I would have needed to start being very conservative with the power.

GELs are at 50%, the other inverter is at 40%. But I see the clouds are thinner this morning so just need it to be like this for 2/3 hours and I’ll be good to go.

Yup and apparently people seem to think you can run a countries power grid on solar... But just three days in JHB indicate this is probably not viable. Plus it's not exactly like JHB gets really windy enough for turbines either.
The clouds this morning are thinner than yesterday and seem to be a bit thinner than Wednesdays so lets see.

Yeah, you can’t. Unless you do that whole oversizing thing and build all over all the provinces. But now if your countries needs is 40GW, you would need at least 120GW or more built all over the country with transmission being able to handle wheeling all that power from one sunny area to another.

But anyway this will trigger more debates🤣. Hopefully the clouds stay thinner and even give us a bit of sun today.

But solar saved Eskom... Which would mean that the three days in JHB should have Eskom wheeling, cause Gauteng is the largest consumer of power.
But yeah hoping it remains thin today :-).
 
What current is each phase typically rated for in 3 phase residential, 60A?
I have no idea about the amps; when i put my order in the company came back expressing concerns about the power being > 16kW, but during my investigation i found a tech spec from Ethekwini, durban.gov.za, of systems up to 100kW for SSEG and residential, so i'm way below that. Not sure what Eskom uses, but i'm no longer Eskom's problem.

Same, went to gym 5 days a week about 20 years ago with a few buddies for 3 months straight, got quite buff, then we took a break for the body to recover.

This is why god invented gennies.

Dont worry, you've done your weeks cooking, now you have 5 days to charge batteries.

Today is good for solar. Not the best but I will easily fully charge. Need only 10kWh or so to get both battery banks full, which I suspect will happen by 1.
 
How long does it take the gels to absorb?
Considering how much they were drained, I need 6/7kWh to charge them up. My guess is around 4 hours. I am slowing it down a bit as there is a constant 1.2kW of load on the 3.6kW inverter at the moment, charging the other inverter and running the pool. PV would be around 3kW right now.

The last 20% takes a while as the current slowly tapers down on the GELS. That's why I estimate around 1, latest 2, the current should be below 10A and entering float.

This is what I'm asking as I know lead acid take forever to absorb so you are saying 4 hours to do the last 20%? So this 4 hour absorb time is a daily thing then if you use 20%?
 
The prediction seems dire though but hopefully it's wrong.

I don't need to those clouds in my life again.

It's actually been full sun my side, seems when they say it'll be cloudy it's sunny and vice versa

Oh, sorry, I meant to say Bulk plus absorption. Bulk would take about 1.5 hour, 2 max. Absorption would be some 2 hours. It's normally quick to get to 28.8V, but it spends some time there. Typically, I would see the current drop to below 10A around 10. Absorption in those days then would be some 1 hours max.

I have slowed this process down considerably, especially now that we are in winter, as at 8, 600W is being dumped into the other inverter constantly for hours. The GELs really only start charging properly around 9 am. But even then, I see it floating around 11:30/12. So absorption is long but not that long.

Sun is out but it's a bit hazy and AQI is tanking again I think with the dust being kicked up by the wind. Top of the boob a bit flat for my liking.
