Hi Oztules Thanks very much for pointing me in the right direction for getting the ferrite cores, they should be here soon.
Lets see if I have got things right please,
Isolate the mains from my grid tie inverter,
With the choke fitted power up the 8000 w Lf.
This will wake up my sonny boy 3600w inverter grid tie
Any excess power from the PV will go through the 8000w LF inverter
and charge the batteries
, but do don't over charge them,
(1) Have I got hold of the right end of the stick
(2) Would 4 turns be better than 3.5 ? on the choke ?
(3) What mods have you in your head for reading Dc power
from inside the 8000 w LF
Your help is invaluable to us all, many many thanks Oztules, Steve.
