Hello all,
My configuration, 2 months old:
4.4kWp PV modules
Multiplus II 48V 3000VA
Smartsolar MPPT 450/100
16xLifepo4 3.2V 280 Ah (only 15 connected now as one pole needs maintenance)
Minerals BMS + Active Equalizer
No Cerbo / Venus
Using the grid only as a backup when the batteries are empty, and not feeding energy to it.
My supplier doesn't have the knowledge to configure correctly the Multiplus in order to set the right priorities for the house loads:
1 From DC storage / solar production
2 When batteries are below 44.3V (15S), switch to grid Passthrough
3 When batteries get charged again above 46V, switch back to DC.
Here is the Ve Config 3 File: conf_15s new.zip
We tried with the Virtual Switch, but seems to me that this DC input low shut-down parameter is interfering with it. Making some tests, opening the DC breaker, the Multi doesn't switch towards the grid, and only shutdowns...
Thank you very much in advance,
Gérard
