and Easy Fit fitted back in the solar sub panel ( a bigger one here) on the Line wire going back the the main consumer panel
Closer look at the solar sub panel and Wattson
Wattson Transmitter is temporarily plugged in and placed here
My consumer unit: See the Wattson Usage sensor is located on the Main Line wire, providing power to the whole apartment; Because the solar sub panel is wired after this, I need to use Easy Fit Y-cable
After going back on the roff the link all the Uni-Solar PVLs together as one string, DC voltage of this big string was then around 360V and the sun was not even shining because of the big white clouds
Now, after closing the SMA Sunny Boy cover panel and wiring it to earth, after switching on the DC and AC breakers, the inverter 3 LEDs blinked for one second, and then nothing ... No display, no LEDs, nothing was on ... :-( and after trying everything my contractor quickly determined that there was probably a problem with this unit ... No Luck
As my contractor advised, on sunday, in the morning sun, I measured again the DC voltage and it was showing 390V; I then tried to start the inverter gain, but still nothing ...
I also read the Sunny Boy 3000 documentation trying to find an explanation in the minimum DC voltage required and in the troubleshooting section
Later on, Mark Elliott from Energeno, Wattson maker, retweeted this pic of Wattson sensors install, with a little comment
