I have a MultiPlus 12/1600/70.
On the seperate control panel toggling left charges the battery and provides 240v to the 3-pin sockets when connected to shore power. Toggling right Inverts when not on shore power. The middle position is off.
Whenever I am on shore power and do not want to charge the battery I leave the Multiplus off (middle position). The problem I have is that when I want to invert (toggling right) whilst on shore power the unit provides 240v as expected but it also charges the battery (the 'Inverter on' lights up for a few seconds on the right side and then turn off, the left lights on the control panel light up showing 'Mains on' and the current state of charge and the battery begins to charge).
If I can harvest some good solar power during the day I do not want to use the shore power to top up my battery when I need 240v.
I could disconnect shore power to resolve this but is there a setting in Venus or on the Multiplus that would prevent this happening?
