Hi David – if you want to try mine version of a energy diverter. I use the fotek SSR that you show ( only in 80 amp) and built home made SSR based on BTA41A… and i being using mine now for 3 years with out issue… but my grid is 60hz but I just made one that universal for any hz - self detecting and configures … you just have to adjust the FRAC and see what the best pulse is for you as I have no experience with 50hz… – how do I determine that is set up a properly is use a ~ -50watt source that shows negative ( imitating uploading to the grid) and then on the element side put small induction motor of some form ie hair dryer or small vent fan-- and then let it pulse it way up it should start turning the the motor at about 10 rpm near it lowest setting and should be fairly smooth all the way up to the to full speed …
this is my cutting edge version so i have not tested it much and nothing with 50hz. but my older version based on standard pwm signal have worked for over 3 year with out issue
65535 step pwm
diveter-auto-hz-detection-65535.zip (5.1 KB)
255 step pwm
Diverter-auto hz-standard.zip (4.9 KB)
these current ones use
servo hardware pwm 16 bit from the Arduino library
you can set it to only use one SSR just set ios to 1 and the grid is CT3 the 16 pwm code is cleaner as I currently was interest in how well that one works ( the 255 - 8 bit version ) works fine it just needs some lines reorder and some safety functions – disabling the PWM if the ac adapter fails…
I also be curious if it works with 50 hz systems
