Conext™ Battery Monitor indicates hours of battery‑based runtime and determines battery bank state of charge. It shares key battery bank parameters with Conext™ Pro and XW inverter/chargers improving overall system performance of 24 V and 48 V battery banks. Detecting battery string imbalance is determined using innovative mid‑point sensing technology providing time to address the issue before performance is significantly impacted. Conext™ Battery Monitor features built‑in data logging and a local display to selectively show the voltage, current, consumed amp‑hours, remaining capacity, and remaining hours. The same information and battery bank data is reported by Conext™ Gateway and distributed to other Conext devices such as XW Pro or XW inverter chargers, MPPT Solar Charge Controllers, Automatic Generator Start module, and System Control Panel via XanbusTM network connectivity, enhancing performance of the overall system.
