Canadian Solar inverter Modbus connection

Hi,

Has anyone made a connection using RS-485 to a Canadian Solar inverter using Modbus RTU or TCP?

Thanks, John

    I heard they make a 3 phase grid inverter?  A bit out of the scope of this forum.

    OK thanks Dave, I did see some folks talking about modbus for other inverters in this form, so I thought I'd ask.

    If you e-mail me, I work with a bunch of solar wrenches that do commercial also. I can ask there.

    I am just testing a Rika RK200-03 Pyranometer, looking good so far. You can use a SolarNode (running on a Raspberry Pi) to acquire the data from it over Modbus RTU, using a USB-to-RS485 adapter. We'll test it out but looks like it should help correlate array performance with a standard watts per m^2 and watt-hours per m^2 set of numbers.
