The AB2000L from Zendure (MPN: AB2000L) is a LiFePO4 auxiliary battery with a rated capacity of 1,920 Wh for compatible Zendure SolarFlow systems. It increases storage capacity by 40 Ah at 48 V and can be combined with additional batteries depending on the system components used. An automatic self-heating function, battery management system protection mechanisms, and an integrated aerosol fire suppression system ensure safe operation within the specified operating conditions.

Capacity and Protection Features

• 1,920 Wh rated capacity at 48 V and 40 Ah
• LiFePO4 cell chemistry with a specified cycle life of 6,000 charge cycles
• Automatic self-heating function within a temperature range of −20 to 0 °C
• BMS protection against overvoltage, overcurrent, short circuit, and overheating
• Integrated aerosol fire suppression system

Connectivity and System Compatibility

Each AB2000L adds 1.92 kWh of rated capacity to a compatible storage system. Up to six AB2000L units can be used with the SolarFlow 800, providing a total of 11.52 kWh. The add-on battery is compatible with the Hub 1200, Hub 2000, Ace 1500, Hyper 2000, the SolarFlow 800 series, SolarFlow 1600 AC+, as well as SolarFlow 2400 Pro and AC+. It can also be connected to batteries from the AB1000 and AB2000 series via the battery connectors. Vertically stacked batteries are connected directly via their terminals. A separately available battery cable is required for connection to the SolarFlow 800, Hub 1200, or Hub 2000. The storage system must be completely powered off before connecting or disconnecting components. Batteries must not be connected or disconnected during a charging or discharging process. The AB2000L does not have its own LED display. Operating status, battery status, and firmware updates are managed via the compatible system component or the Zendure app. Additionally, the battery offers the following protection features:

• Overcurrent
• Short circuit
• Overvoltage
• Overheating protection

Temperature Range and Installation

The battery can be charged at temperatures between 0 and 55 °C and discharged at temperatures between −20 and 60 °C. At low temperatures, an automatic self-heating function is available between −20 and 0 °C. This does not constitute approval for charging outside the specified charging temperature range. The battery is intended to be installed on a level, secure, and frost-free surface in a shaded location. Direct sunlight, heat sources, liquids, and extreme weather conditions must be avoided. A minimum distance of 50 mm must be maintained from surrounding objects.
