in Grid Tie and Grid Interactive Systems #1
I'm a decent electronic tech.   My 30kw solar grid tie system is all Sunny boy.  3 are SWR2500u.  I also have 4 non working of them with various errors.  One K1 open,  one no errors but no output,  and one gnd error (will try reset).   If I can get a schematic I can test and possibly repair them.  I have one in service now that is giving a Vac-bfr error then goes to waiting… then works if panel input is low… if solar high the back to error and loops.  I would like to keep that inverter same type because of room.   Any help… please.

    There was a guy in the San Fernando Valley that repaired Sunny Boy inverters Lots of them. I believe his name was Compu Hans You might try to look him up, I imagine he could give you some good info
