    SmallBMS NGThe SmallBMS NG is an all-in-one Battery Management System (BMS) designed for Victron Lithium NG batteries (not compatible with lithium smart batteries). It monitors and protects the batteries by managing charge and load disconnects and providing pre-alarms for low battery voltage.The SmallBMS NG is a straightforward and cost-effective alternative to the VE.Bus BMS NG for applications that don’t require integration with Victron inverter/chargers. It provides essential lithium battery protection without the added complexity of VE.Bus communication is therefore not suitable for use with VE.Bus inverter/chargers such as MultiPlus and Quattro.With built-in Bluetooth, it connects directly to all lithium NG batteries in the system for central monitoring via VictronConnect. It also receives current and state of charge data directly from the batteries, so there’s no need for a separate SmartShunt.The lithium NG batteries can be configured in series, parallel, or a combination of both, supporting 12V, 24V, and 48V systems. A maximum of 50 batteries can be used in 12V or 24V banks, and 25 batteries in 48V banks, enabling up to 192 kWh (12V), 384 kWh (24V), and 128 kWh (48V) of storage. Multiple Lynx Smart BMS units can be paralleled to expand capacity and ensure redundancy.Features: Load disconnect output: Controls the remote on/off input of a BatteryProtect, inverter, DC-DC converter, or other loads with remote on/off functionality to prevent deep discharge. Charge disconnect output: Controls the remote on/off port of chargers such as the Smart IP43 Charger, a Cyrix-Li-Charge relay, a Cyrix-Li-ct Battery Combiner, or a BatteryProtect, to prevent overvoltage. Pre-alarm output: Provides early warning for low battery voltage before disconnecting loads. Can drive a relay, LED, or buzzer. Remote on/off control: Allows external control of both load and charge disconnect outputs. LED indicators: Includes a blue LED for Bluetooth status and a red LED for warnings and errors.

    SmartSolar MPPT Charge Controller - 75V - 15AMPFeatures: Bluetooth Smart built-in The wireless solution to set-up, monitor, update and synchronise SmartSolar Charge Controllers.  VE.Direct For a wired data connection to a Color Control GX, other GX products, PC or other devices  Ultra-fast Maximum Power Point Tracking (MPPT) Especially in case of a clouded sky, when light intensity is changing continuously, an ultra-fast MPPT controller will improve energy harvest by up to 30% compared to PWM charge controllers and by up to 10% compared to slower MPPT controllers.  Load output Over-discharge of the battery can be prevented by connecting all loads to the load output. The load output will disconnect the load when the battery has been discharged to a pre-set voltage (48V model: interface with a relay). Alternatively, an intelligent battery management algorithm can be chosen: see Battery Life. The load output is short circuit proof.  Battery Life: intelligent battery management When a solar charge controller is not able to recharge the battery to its full capacity within one day, the result is often that the battery will continually be cycled between a ‘partially charged’ state and the ‘end of discharge’ state. This mode of operation (no regular full recharge) will destroy a lead-acid battery within weeks or months. The Battery Life algorithm will monitor the state of charge of the battery and, if needed, day by day slightly increase the load disconnect level (i.e. disconnect the load earlier) until the harvested solar energy is sufficient to recharge the battery to nearly the full 100%. From that point onwards, the load disconnect level will be modulated so that a nearly 100% recharge is achieved about once every week.  Programmable battery charge algorithm See the software section on our website for details  Day/night timing and light dimming option See the software section on our website for details  Internal temperature sensor Compensates absorption and float charge voltage for temperature.  Optional external battery voltage and temperature sensing via Bluetooth A Smart Battery Sense or a BMV-712 Smart Battery Monitor can be used to communicate battery voltage and temperature to one or more SmartSolar Charge Controllers Warranty InfoWARNING: This product can expose you to chemicals which are known to the State of California to cause cancer, birth defects or other reproductive harm.
