The Silverleaf is not a controller. It is more an interactive reporter that can communicate back to other controllers and management systems to turn things on and off. I know the lithium ion battery energy management system comes fro Elite Power Systems. They have a computer chip connected each Individual battery cell. Thefitrv.com posted a video discussing the batteries. I've learned first hand the battery bank will not accept charging if the batteries drop below freezing. It is also controlled to shut down power arbitrarily at 20% without a hard charge reset. The user can increase that for a soft reset with Autogen. I haven't got close to my arbitrary setting of of 25% but others have. Charging input can come simultaneously from shore, solar and alternator. At about 90% the charge rate starts to progressively slow down to float at 99%.
