SOLARMAN Smart power plant set up

[Willie Trombone]

I've just set up SOLARMAN Smart on my phone and managed to add my 'plant' and give details of production / storage / etc.

What I'm not sure of is the kWp rating of my system. Does anyone have any suggestions? I have 2x parallel strings of 6x450W 48v panels on each string. What should I set as the kWp for these things?

Also, for anyone else using the system, real-time is not really real-time as I guess I should have expected. It's a bit delayed. I tested by running heavy loads and got it to 4.7kW but the app was telling me 600W max in real-time. A minute or two later I saw the blip on the graph... I imagine it's not talking to the web 24x7 but rather pushing stats every x seconds / minutes. I assume the logger has a small buffer.

I assume it would be the total output of what your panels are rated at, as that would be peak performance. Real world will always be lower. So 12 x 450 = 5.4 kWp...

Thanks... was wondering the same... can anyone else back that up?
I know real world will definitely be lower but still, would be good to be able to calculate as near as dammit.

I have mine set to my inverter capacity and it reads accurately.

I have mine setup the same..14x455W=6350kwp..
In terms of monitoring, Solarman is quite delayed, look into monitoring it with Home Assistant it's free, and it's in real time, or you could check out Solar Assistant, but thats a paid for piece of software...

Thanks will check out home assistant.

Kwp is the sum total of all of your panels' capacity as strung, the maximum that they will should ever produce at STC, assuming perfect azimuth and pitch.

I have 12x 380W and 4x 390W, 6x380W and 2X 390W per string (and per MPPT). The four 390W panels therefore perform as 380W panels, so 16x 380W = 6,080kWp.
