Hi, i am a newbie and struggling with a new installation.
9kw solar panels with 5kw sunny boy and 4kw sunny boy both on FIT
Quattro 10kw with colour CGX/wifi module (not ordered a mk3 usb yet)
1240ah Lead acid batteries
Want to set it up so i only use grid power when batteries get down to say 40% and or solar subsides at night
Cant seem to work it out have tried using the remote vec configure but all i can do is charge batteries and put excess down the grid but it goes back to mains draw when solar dips
It will power all when i switch off the mains but not switch to just batteries when the solar subsides at night.
Is there anyone who can help me set this up and understand it as i am sure it can do it but i am not clever enough to work it out.
Any one able to help?
