Conecting inverters Without data to Pvoutput


#1

I have two klne Solartec 3000 inverters one on the house and one on the shed.
And they work very well and have for the last 4 years.
But they have no internal rs232/485 or wifi, the coms software so not in there version of the software.

So I’m wondering if anyone has added a meter our shunt, or logger to get them measurements, and data they can measure to monitor, there output.

At the moment I record the total kWh of the display of both inverters each morning, when i walk out to get the paper.

Hope somebody has an idea or two.

Thanks for all the interesting reading.

Perhaps you could start by googling “measuring power from PV inverters with cts” and see what is available.
I got this page with this:

Checkout this thread - Consumption, who's using what?

The same consumption monitors should be able to be clamped on to the inverters’ wires and provide solar generation for you.
