Hi. I'm having an issue with Quattro and Multiplus inverters continuing to send a small amount of current to the batteries even though the batteries are at 100% and the charge current is supposed to be 0. This only happens when connected to a genset, the systems work properly when connected to the grid. I have tried the assistant that is supposed to turn off the charger when charge current is 0 but this has no effect. Any help would be much appreciated.
