Differentiators
Engineered with a dedicated synchronization bus that aligns charge distribution automatically between expansion units and the host AC500 controller. This native communication protocol enables precise state-of-charge tracking without external monitoring hardware, while maintaining independent low-voltage load operation when deployed as a standalone unit.
