The COM3 and COM4 ports (LYNK ports) enable multiple Discover batteries to communicate and interact in a closed-loop network. The LYNK ports also enable the HELIOS ESS batteries to work together in a closed-loop communication system with other networked devices, such as inverter-chargers. A closed-loop system enables safety and optimizes system performance.
