Smart meter P1 AC values + Power One inverter

Post by cj0 » Fri Nov 20, 2020 12:24 pm

Hello, I am new here. A friend made me aware of 123solar.

My situation might be non typical. For a few (Power One PVS-60 = 480VAC) inverters there is a dedicated grid connection with a dedicated (Dutch) Smart Meter for each inverter. Thus there is also a 480 to 400VAC transformer. I'd like to see the "official" AC values from the Smart Meter in 123solar.

For selected inverters I'd like to extend (or override) 123solar inverter logging with Smart Meter phase voltages and power.

Any suggestions how to approach this?

Hi,
That would need to adapt the scripts/protocols/aurora.php file.
Somewhere near line 75

Code: Select all

$P1values = exec("something to get your smart's meter grid values");
$decodedP1 = do somethings;
..
$G1V =  "grid phase 1 data from $decodedP1";
..
$G2V =  "grid phase 2 data";
..
$G3V =  "grid phase 3 data";
..
Try first to write a small php script that return grid value

Hi Jeanmarc,

Thank you for your quick and to the point reply.

Are the aurora.php customizations lost after a 123solar version upgrade?

PS1 I'd also wish to set the power value, which variable is that?
PS2 I still need to connect the RS485 network and PoE RPi, so expect it will take a few weeks before I can try.

yeah that will be lost after update.
You can see all variables details in scripts/protocols/_protocols.txt
