Solar generation in rain/cloudy conditions

[wingnut771]

Crazy good AQI today in JHB - 22! Not sure if you guys are noticing a very good harvest for today so far but I've been getting about 93% efficiency.

How much? Dbn is 38:

I had done 19kWh by midday with my 5.5kWp. That's good for me - anything 15 and up by midday is a good day, although usually the cloud build up comes later in the day.

No chance of boobs with me in summer ..
By 11am I have lopsided tits
Even today with quite a bit of cloud I was full by 1pm
Distinct difference from Winter

 

[Next Thing]

No real difference in my use from winter to summer
March/April/May was still getting setup properly with geyserwise and proper monitoring
Now mostly offgrid with only really having to use grid in Winter if a few days of cloud.
Started measuring water usage this month .
Gas saving using hybrid on the gas geyser since July kg = ~L/2

Payback on everything is solidly looking like 3.1 years now without factoring in increases
Monthly Savings between 8k and 10kpm

My tits are all sad


Or hooker style ( She still got her 100% sallary ) lol

Only 85% efficiency charging LFP

Ranges between 88% - 95% on the sunsynk depending on the month so dunno, maybe 5A isn't efficient?

What would you say are acceptable temps?

This feels a bit high.

Its charging on 30A.

Maybe the sunsync has better efficiency

The inverter will tell you if it's unhappy. Otherwise, it's okay.

First full day with solar and it's cloudy... for the next few days.

I removed the standard fans from my Sunsynk and replaced it with 3 12x12 240v Hongbo fans connected to a seperate temperature sensitive relay switch which switches the fans on and off at set temperature ranges. The switch picks up the temperature from the DC circuit which always run hotter compared to the AC circuit.

The picture shows the result

I also have 4 x 95mm PC fans in a 3d printed housing on the extraction side, sucking constantly.

Are your fans a direct replacement? What inverter do you have. I have the 8kw Sunsynk.

Same inverter as you.

I removed the standard fans and replaced them with the Hongbo fans. I did at a point in time test a set up similar to yours (standard fans connected and these sucking on the outlet side), but found the improvement to only be marginal.

This time of year its not a problem, your battery is probably full already?
