I like the fonrich unit but I still have a problem with it tripping . The tigo ts4-A0 optimizers cause bursts of noise about every 3 seconds that cause the fonrich to trip unless the fonrich is set to 127 , which is the most desensitized. Tigo did some updates and I thought it would work but...
I think I know the answer to this but could the dc bus of the inverters be tied together without batteries to allow current sharing / parallel operation ?
No I actually re did my wiring , to get the ac and dc away from each other . I actually think it’s a problem in the deye itself . I ordered a 3rd party stand alone arc fault system but have not had a chance to install yet
