About product

The Discover AES batteries are an excellent choice for applications needing deep cycling on a daily basis as needed for off grid, self-consumption, peak load shaving, and other similar systems. They use the commonly preferred Lithium Iron Phosphate (LiFePO4) chemistry for stationary energy storage. It is thermally stable and has high cycle life compared to many other Li-ion technologies. The AES 42-48-6650, and AES 44-48-3000 batteries can be used with most 48 V inverters and charge controllers with closed loop communication or without as a lead battery replacement.  

AES batteries have a built in Battery Management System (BMS) that keeps the individual cells balanced and within the correct parameters for longest life. If operating parameters are exceeded for over 2 minutes the battery will shut down. The BMS monitors cell module voltage, battery voltage, battery current, battery temperature, and battery state of charge. It keeps a log of this data and can send out fault and warning events. There is an AEBus connection for communications between multiple batteries. Each battery has an ON/OFF switch and an internal backup fuse.

The Xanbus port on the 42-48-6650 will work directly with Schneider Xanbus network systems. It reports to the Xanbus network as a battery monitor device. There is also a comm port on all of the batteries for connection to the Discover LYNK© monitor and communication box. Xanbus Edge Cards (daughter boards) can be added to the LYNK© to enable communications to specific inverter brands. The 44-48-3000 can communicate to the LYNK© and with a Schneider Edge Card to the Schneider Xanbus network. A selection of cards are available to match popular inverter brands. Two Edge Cards can be used at one time for various inverters and charge controllers in one system. LYNK© enables closed loop communications providing adaptive, real­ time interaction between the Discover AES LiFePO4 battery and connected inverter system. Remote reporting of battery status is available through the inverter monitoring and web services.
