Detailed description

Koncipiran kot celoviti sistem za upravljanje baterij (BMS), je smallBMS NG podjetja VICTRON ENERGY namenjen baterijam Victron Lithium NG (LiFePO4) z napetostjo 12,8 V, 25,6 V in 51,2 V. Omogoča ustvarjanje baterijskih polj v seriji, vzporedno ali mešano za sistemske napetosti 12 V, 24 V ali 48 V. Ta BMS upravlja do 50 baterij za sisteme 12 V ali 24 V ter do 25 baterij za sisteme 48 V, kar omogoča največjo kapaciteto shranjevanja 192 kWh (12 V), 384 kWh (24 V) ali 128 kWh (48 V).

Povezljivost in funkcije kontrole

smallBMS NG vključuje tehnologijo Bluetooth Smart, ki omogoča konfiguracijo, spremljanje in posodobitve programske opreme na daljavo preko aplikacije VictronConnect. Funkcija »Instant Readout« omogoča prikaz ključnih podatkov, kot so stanje polnjenja (SoC), temperatura baterije, opozorila in alarmi neposredno iz seznama naprav. Ima izhod za odklop polnjenja (max 500 mA, nezaščiten pred kratkim stikom) in izhod za odklop porabe (max 1 A, nezaščiten pred kratkim stikom), ki omogočata daljinsko vklop/izklop vhodov naprav BatteryProtect, DC-DC pretvornikov, inverterjev ali kompatibilnih polnilk, kot so Smart Charger IP43 ali releji Cyrix-Li-Charge in Cyrix-Li-ct.

Varnost in upravljanje energije

Za varnost baterijskega polja je izhod za predalarm aktiviran vsaj 30 sekund pred izklopom izhoda za odklop polnjenja v primeru podnapetosti celice, kar lahko upravlja relej, LED ali zvočnik (max 500 mA, nezaščiten pred kratkim stikom). Terminal za daljinsko vklop/izklop omogoča zunanjo kontrolo izhodov za odklop. smallBMS NG ponuja nastavljiv prag izpraznitve, da prepreči prekomerno izpraznitev in ohranja rezervno energijo. V primerjavi z VE.Bus BMS NG je smallBMS NG preprostejša in bolj ekonomična alternativa brez vmesnika VE.Bus, zaradi česar ni primerna za inverterje/ polnjalnike MultiPlus in Quattro VE.Bus. Njegova ohišje iz črnega matiranega ABS-ja nudi zaščito IP20, kompaktne dimenzije (106 x 42 x 23 mm pri 0,1 kg) pa olajšujejo vgradnjo. Deluje v napetostnem območju od 8 do 70 V enosmerne napetosti in v temperaturnem območju od -20 do +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 at 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 cost-effective 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 a maximum of 50 batteries to be connected 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 in parallel with this BMS?

Yes, Victron Lithium NG batteries can be connected in series, in parallel, or in a combination of both. This allows for battery banks with system voltages of 12V, 24V, or 48V using 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 device list of the VictronConnect app 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 purpose of the load disconnect output (Charge disconnect)?

The load 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, thereby 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 features a configurable 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 performed 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 avoid damaging the battery.

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 smallBMS NG’s current draw in 'remote on' mode is 3 mA (excluding load disconnection output current and consumption).
The current draw at low cell voltage is 1.2 mA.
The current draw 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 IP rating of the smallBMS NG?

The smallBMS NG has an IP20 rating.

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

The smallBMS NG is specifically designed for Victron Lithium NG (LiFePO4) batteries of 12.8V, 25.6V, and 51.2V. It can control loads and chargers with a remote on/off input, such as BatteryProtect, DC-DC converters, certain inverters, Smart Charger IP43, 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 VE.Bus MultiPlus and Quattro inverters/chargers.
