Solar generation in rain/cloudy conditions

I see this uses the Deye Cloud API, is it limited to 5 minute intervals for updates like the web based portal?

If I go onto Deye Cloud on the PC and go into the logger, it says 1min not sure if yours is the same?

I checked now and see it is set to 1 minute, I am used to the SunSynk Cloud API being 5 minutes, that and the fact that they had a lot of down time led me to use Solar Assistant.

I think the older Deye's with the Solarman dongle are all 5min
 
WTF . Were my panels that dirty or was there that much gunk in the air
last week I was battling to get peaks of 9kw
Today almost 12 , almost my theoretical max

Lots of cloud-edge effect happening today but yes, AQI right now is actually outstanding by highveld standards at least for this time of year. Also the cool temps help. Ignore the spikes and look at the trend. In my case I'm seeing around 87% avg. efficiency at the moment which is great. AQI in JHB right now: 26 (basically unheard of).

Also definitely would have helped to have that free panel wash.
 
Did manage to generate 18kWh so far, not sure it's going to be much more today as the sun disappearing.

About what I'm going to need to get pool back in order after this leaf deluge. 😒

So far done 8kWh. 3 of which went to the GELs I see. The fishpond and pool were left to run (I wouldn't have left them on but it's their place now lol). The 5kW inverter's LFP is nowhere near full but it's not the important inverter so I guess it doesn't matter.

what app is this and what inverter / system do you have?

Deye 21kw 3 phase LV , 2 x 16kw Hinaess , About 12kw of panels
Automation is via Home assistant . The card II put above is one another local SA guy designed

https://slipx06.github.io/sunsynk-power-flow-card/index.html
I use that + mixture of standard HA energy dashboard
Use the deye addon that gets stats from the cloud every minute

And a crap ton of automations that atm can save me 10 to 15kwh per day on shitting generation days

Considering how relatively cheap solar panels are, guys should try max out their strings where ever possible.

Got 56 kw/h today.

That is the plan in the future. Seeing the figures for most here with 10 to 12kWp arrays I will aim for 17 to 18. Long into the future plans though as I kinda like the country where I am now and have no interest in coming back to SA anytime soon if ever. Maybe can do it if renting to people other than family that need more power, but I would rather leave the house empty and pay security extra than rent to people in SA with the laws there.
 
With Sunsynk 8kva inverter , what is the theoretical PV max one can install across the two MPPTS?

On one MPPT, I have 8x 545w (first install) - all installed together
Second MPPT, 8x 600w, in 2 , 2, 4 config. One of the 2 panels seriously fscks up generation , as in winter, tree is still blocking them until 11am.

All on North facing and I have space for putting 8 more without being affected by trees. And the entire South facing roof, which could hold 20 panels itself not that I wanna put anything there.

Hoping with the extra PV, to put a heat pump for the pool

I know voltage is important, but also recall reading inverter can deal with super clipping
 
This is the most I’ve seen since getting the logger installed. Not much load left to run though so won’t go much higher.

I'm seeing 10400W to 12800W depending on the specific model.

For my 12kw 3 phase sunsynk it's 15600W so seems about right?
