Detailed description

Dissenyat com un sistema de gestió de bateries (BMS) tot en un, el smallBMS NG de VICTRON ENERGY està dedicat a les bateries Victron Lithium NG (LiFePO4) de 12,8 V, 25,6 V i 51,2 V. Permet la creació de parcs de bateries en sèrie, paral·lel o mixt per a tensions de sistema de 12 V, 24 V o 48 V. Aquest BMS gestiona fins a 50 bateries per a sistemes de 12 V o 24 V, i fins a 25 bateries per als sistemes de 48 V, amb una capacitat màxima de 192 kWh (12 V), 384 kWh (24 V) o 128 kWh (48 V).

Connectivitat i Funcions de Control

El smallBMS NG integra la tecnologia Bluetooth Smart, que permet la configuració, la supervisió i les actualitzacions de firmware sense fil mitjançant l’aplicació VictronConnect. La funció « Instant Readout » permet visualitzar les dades clau com l'estat de càrrega (SoC), la temperatura de la bateria, els avisos i les alarmes directament des de la llista d’aparells. Disposa d’una sortida de desconnexió de càrrega (màx. 500 mA, sense protecció contra curtcircuits) i d’una sortida de desconnexió de consum (màx. 1 A, sense protecció contra curtcircuits) per controlar les entrades d’engegada/aturada a distància de BatteryProtect, convertidors DC-DC, onduladors o carregadors compatibles com el Smart Charger IP43 o els relés Cyrix-Li-Charge i Cyrix-Li-ct.

Seguretat i Gestió Energètica

Per a la seguretat del parc de bateries, una sortida de pre-alarma s’activa com a mínim 30 segons abans de la desconnexió de la sortida de càrrega en cas de baixa tensió de cel·la, i pot controlar un relé, un LED o un brunzidor (màx. 500 mA, sense protecció contra curtcircuits). El terminal d’engegada/aturada a distància permet un control extern de les sortides de desconnexió. El smallBMS NG ofereix un llindar de descàrrega configurable per evitar descàrregues excessives i mantenir una reserva d’energia. En comparació amb el VE.Bus BMS NG, el smallBMS NG es presenta com una alternativa més senzilla i econòmica, sense interfície VE.Bus, cosa que el fa inadequat per a onduladors/carregadors MultiPlus i Quattro VE.Bus. El seu xassís d’ABS negre mat ofereix una protecció IP20, i les seves dimensions compactes (106 x 42 x 23 mm per a 0,1 kg) en faciliten la integració. Funciona en un rang de tensió de 8 a 70 Vcc i una temperatura de -20 a +50 °C.

Frequently Asked Questions

Need help? Contact us

What is Victron Energy's smallBMS NG?

The smallBMS NG is an all-in-one battery management system (BMS) designed for Victron Lithium NG (LiFePO4) batteries in 12.8V, 25.6V and 51.2V. It enables the creation of battery banks for system voltages of 12V, 24V or 48V, while ensuring their protection and management.

Which batteries is the smallBMS NG compatible with?

The smallBMS NG is exclusively compatible with Victron Lithium NG batteries. These are Lithium Iron Phosphate (LiFePO4) batteries available in 12.8V, 25.6V and 51.2V.

What is the difference between the smallBMS NG and the VE.Bus BMS NG?

The smallBMS NG is a simple and economical alternative to the VE.Bus BMS NG. The main difference is that the smallBMS NG does not have a VE.Bus interface, making it unsuitable for use with MultiPlus and Quattro inverters/chargers equipped with a VE.Bus interface.

How many Lithium NG batteries can be connected with the smallBMS NG?

The smallBMS NG allows connecting a maximum of 50 batteries for 12V or 24V bank configurations. For 48V systems, up to 25 batteries can be used.

What is the maximum storage capacity supported by the smallBMS NG?

The smallBMS NG supports a maximum storage capacity of:

192 kWh with 12V batteries. 384 kWh with 24V batteries. 128 kWh with 48V batteries.

Can the batteries be connected in series or parallel with this BMS?

Yes, Victron Lithium NG batteries can be connected in series, in parallel, or a combination of both. This allows battery banks to be configured for 12V, 24V or 48V system voltages with the smallBMS NG.

How can I configure and monitor the smallBMS NG?

The smallBMS NG integrates Bluetooth Smart technology, enabling wireless configuration, monitoring, and firmware updates. This is done via the VictronConnect app, available for Apple and Android smartphones and tablets.

What is the "Instant Readout" function in VictronConnect?

The 'Instant Readout' function displays key battery and BMS data such as state of charge (SoC), battery temperature, warnings, and alarms. This information appears directly in the VictronConnect device list without requiring a connection to the product.

What is the Load Disconnect output used for?

The Load Disconnect output controls the remote on/off input of a BatteryProtect, inverters, DC-DC converters or other loads with a remote on/off function. It disconnects these loads in case of imminent cell undervoltage.

What is the consumption disconnect output (Charge disconnect) used for?

The consumption disconnect output controls the remote on/off port of chargers, such as the Smart Charger IP43, a Cyrix-Li-Charge relay, a Cyrix-Li-ct battery combiner, or a BatteryProtect. It interrupts charging in case of imminent cell overvoltage or temperature issues.

What is the function of the pre-alarm output?

The pre-alarm output triggers a visible or audible warning when battery voltage is low. It activates at least 30 seconds before the load-disconnect output is disabled due to cell undervoltage. It can drive a relay, LED, or buzzer.

How does the remote on/off terminal of the smallBMS NG work?

The remote on/off terminal enables external control of load disconnect and consumption outputs. When disabled, both outputs become floating, thus turning off connected loads and chargers. It consists of two terminals (Remote L and Remote H) and can be actuated by a switch, relay contact, or by pulling the terminals to ground or battery positive.

How does the smallBMS NG protect against excessive discharge?

The smallBMS NG has an adjustable discharge threshold (discharge floor) that sets the minimum SoC. This prevents excessive discharge and ensures sufficient energy remains for self-discharge after a low SoC shutdown. A low SoC warning is triggered, activating the pre-alarm output, before a low SoC alarm cuts loads via the ATD output.

What are the important safety precautions when installing Lithium batteries with the smallBMS NG?

It is crucial to follow national safety regulations. Installation must be carried out by qualified installers. Do not discharge a new lithium battery before it has been fully charged, and charge it only within the specified limits. The battery must be installed in a ventilated area and must not be mounted upside down or in a living space. It is also important to ensure there is no residual current draw when the system is not in use to prevent battery damage.

What is the operating voltage range of the smallBMS NG?

The operating voltage range of the smallBMS NG is 8 to 70 Vdc.

What is the current consumption of the smallBMS NG?

The current consumption of the smallBMS NG in 'remote on' mode is 3 mA (excluding load disconnection output current and consumption). The current consumption in case of low cell voltage is 1.2 mA. The current consumption in 'remote off' mode is 1.2 mA.

What are the dimensions and weight of the smallBMS NG?

The smallBMS NG has the following dimensions (height x width x depth): 106 x 42 x 23 mm. Its weight is 0.1 kg.

What is the operating temperature range of the smallBMS NG?

The smallBMS NG can operate within a temperature range of -20 to +50 °C (0 to 120 °F).

What is the protection rating (IP) of the smallBMS NG?

The smallBMS NG has an IP20 protection rating.

Is the smallBMS NG compatible with all Victron Energy inverters/chargers?

The smallBMS NG is specifically designed for Victron Lithium NG (LiFePO4) batteries at 12.8V, 25.6V, and 51.2V. It can control loads and chargers with a remote on/off input, such as BatteryProtect units, DC-DC converters, certain inverters, Smart Charger IP43 models, as well as Cyrix-Li-Charge and Cyrix-Li-ct relays.

However, the smallBMS NG does not have a VE.Bus interface. It is therefore not suitable for use with Victron Energy’s VE.Bus MultiPlus and Quattro inverters/chargers.
