This is a dual input CC with a 250 VDC input voltage rating, and maximum charge current of 120 amps. I bought this because my existing Midnite Classic 200 shuts down at extreme cold temperatures when the open circuit voltage goes slightly above 200 VDC. Though this CC does work at the low temperature, I'm not happy with the configuration flexibility. I think this is probably made to work with an integrated Growatt system, which I don't have.

Asking $150 plus shipping.

Is it tough to set up or does it not have good flexibility?
I don't like the user interface, but it's more frustrating than difficult. If you miss your entry you have to step through the 20 odd settings to get back to the one you were interested in. The flexibility is very limited though. My main complaint was that it has an algorithm for determining absorption time, you can't set it manually. I expect this is the way all the Growatt interfaces work. I'm sure you could find some videos on YouTube.
