Hi,
I have been using the Multuplus II for about 1/2 year with lead acid batteries and it has been working fine.
Now i have switched to a 24V 912Ah Lifepo4 pack and have issues with the inverter only using grid power.
the batteries are at 100%, but the inverter ignores it and only uses grid. the only way i can use the batteries is by removing the grid connection. then it has no issues using batteries.
i have reset the setting via my notebook and all, but it still does not want to use the batteries.
there must be something i am missing, as before, it would deplete the batteries, change over to grid and then back to batteries once we have enough sun.
Am also using Venus OS and it shows me only the error for inverter, nothing else any more.
it usually shows me the victron smart shunt and victron MPPT 150/100 as well.
would be great if someone has any pointers.
Thanks
Martin
