I know I should know this….but if I am parked with shore power, the solar will keep the lithium’s at 90-100% at all times. Is there a way to limit it to 80% SOC? Can you set it to a certain voltage level (i.e. 13.2v or so) to achieve this? I have a Victron SmartShunt, but I am not sure it will talk to the SmartSolar (at least for SOC).

For now, I am managing this manually, by shutting off the solar charging until the batteries get low enough to charge….but then I have to catch it before it gets to 80%. I have the magnum charging off.

Thoughts?
