For the time being I have a generator with a «bad» sinoid curve. Until recently I only used the generator to charge my 12V batterybank. From the batterybank I had an inverter to make 230V for my offgrid cabin. I have now thrown out the separate battery charger and inverter in favor of a Multiplus 12/1600/70-16.
My question is, when I run the generator I want it to only charge the batteries and not let the «bad» power into my 230V system. Is it possible, and how do I do it?
