I just bought a Growatt Charge Controller | SC48120-MPV and after powering the device on with or without any PV connected the device powers off. No error codes listed on the display or fault lights active. the small circuit board in the PV /BAT compartment also appears to turn off. If I power cycle the device via the power button or battery breaker feeding the device it powers back on and then shuts off again about 30 seconds later.
Is this some setting I am missing or did I get a defective device?
 
Yeah, it turns out this is a feature. I am guessing it's for power savings. Then the sun comes out and the PV has voltage the device wakes up.
