I would be happy with some help. First time installing an AC coupled system with Victron + Fronius. Have difficulties finding the good ESS Assistant settings.
Fronius PV Inv Primo 4
Multi II 48/5000
simpliPhi ion lithium batteries (client's reqrt)
NO export to grid allowed
wish to find the best setting via ESS for solar / battery priority as follows :
- Solar to supply loads via Fronius
- Excess to recharge the batteries
when no sun or not enough :
1- use from battery via MII
2. If not enough, let Grid IN but without recharging batteries.
Have set mini grid on fronius with freq shift
1 to 1 rule respected
FRONIUS on AC out (loads)
Very familiar with VS / OFF grid / DC coupled settings in VeConfig . Not too familiar with Ess.
Have read most Victron docs . looked at Fronius/Victron webinars.....
Probably missing something.
For now Grid is charging batteries and suoplyung loads ....
Thanks for any tip or link ....
