victron energy 2497273 Smart BatteryProtect 12-24V

Installation

1. The Smart BatteryProtect (SBP) must be installed in a well-ventilated area and preferably close (max 50 cm) to the battery (but, due to possible corrosive gasses not above the battery!). Voltage drop over a long or undersized cable between the battery plus and the SBP may result in a short circuit alarm when starting-up the load, or unexpected shutdown.
2. A properly sized fuse must be inserted according to local regulations in the cable between the battery and the SBP.
3. The SBP is designed to allow current to flow from IN (battery) to OUT (load) terminals only. Reverse currents from OUT to IN terminals are strictly forbidden, and will damage the device. If you wish to use the SBP as a disconnection for a charge source, you must orient the unit in the system so that the current is flowing in the intended direction, IN to OUT.
4. The short circuit protection of the SBP will be activated if you try to directly connect loads with capacitors on their input (eg inverters). For that use case, please use the SBP to control the remote on/off switch on the inverter, instead of disconnecting the higher power DC line.
5. Use a 1,5mm² wire (included) for the minus connection, which should be connected directly to the battery minus (or the chassis of a vehicle). No other equipment should be connected to this wire.
6. The SBP automatically detects the system voltage one time only after connection of plus and minus to the battery. The selected voltage (12 or 24V) is stored, and further automatic detection is disabled. See in the programming table for how to reset it when re-using the SBP in a different installation or use Bluetooth.
7. Do not connect the load output until the SBP has been fully programmed.
8. A remote on-off switch can be connected between Remote H and Remote L (see figure 1). Alternatively, terminal H can be switched to battery plus, or terminal L can be switched to battery minus.
9. A buzzer, LED or relay can be connected between the alarm output and the battery plus (see figure 1). Maximum load on the alarm output: 50 mA (short circuit proof).

Load disconnect events and alarm output options
Buzzer or LED mode (buzzer or LED connected to the alarm output):

• In case of under voltage, a continuous alarm will start after 12 seconds. The SBP will disconnect the load after 90 seconds and the alarm will stop. Reconnect delay: 30 seconds.
• In case of over voltage, the load will be disconnected immediately and an intermittent alarm will remain on until the overvoltage problem has been corrected. There is no reconnect delay.

Relay mode (relay connected to the alarm output):

• In case of under voltage, the relay will engage after 12 seconds. The SBP will disconnect the load after 90 seconds and the relay will disengage.
• In case of over voltage, the load will be disconnected immediately and the alarm output will remain inactive. Overvoltage trip levels: 16V respectively 32V

Li-ion mode:

• Connect the load disconnect output of the VE.Bus BMS to Remote H terminal. The load is disconnected immediately when the load-disconnect output of the VE.Bus BMS switches from ‘high’ to ‘free floating’ (due to battery cell under voltage, over voltage or over temperature). The under voltage thresholds and alarm output of the SBP are inactive in this mode.

Operation

There are 6 possible error modes, indicated by the 7 segment display and on a Bluetooth enabled device:

• Short circuit detected
• Overload or over-temperature / P2 over-temperature warning
• Under-voltage / P3 under-voltage warning
• Overvoltage
• Settings Failure
• Reference Voltage Failure
• BMS Lockout

After 5 minutes the error is no longer displayed to reduce current consumption. The decimal point of the 7 segment display is used for status indication:

• On solid: the SBP attempts to activate the output
• Flash every 5s: output is active
• Flashing every 2s in Li-ion mode: output ‘connecting’

Remote control and short circuit

• The SBP will connect the load 1 second after closing the remote contact.
• The SBP will disconnect the load immediately when the remote contact is opened.
• When in Li-ion mode the SBP will observe a dead period of 30 seconds after the remote input of the SBP has become free-floating. See the note under figure 4 for a detailed description.
• In case of a short circuit, the SBP will attempt to connect the load every 5 seconds. After two attempts the display will show  (short circuit detected).

Programming
When switched off (remote open), the SBP can be programmed by connecting the PROG pin to the ground. Alternatively, it can be programmed with a Bluetooth- enabled smartphone or tablet regardless of the remote status.
The 7-segment display will first step through the shutdown and restart voltages. Disconnect the PROG pin when the desired voltage is displayed.
The display will confirm the chosen voltage and default mode twice.
Reconnect the PROG pin to the ground if another mode is required. Disconnect when the required mode is displayed.
The display will confirm the chosen voltage and mode twice.
Bluetooth can be disabled/re-enabled with the VictronConnect app or by connecting the PROG pin to the ground and selecting (enable) or (disable).See table below

Figure 4: System with Li-ion battery (applicable with VE.Bus BMS or mini BMS)
Note: When in Li-ion mode, the SBP will disengage when the H input becomes free-floating and will remain disengaged for 30 seconds even if it receives a re-engage signal within that time period. After 30 seconds it will respond immediately to a re-engage signal. Therefore, there will normally be no waiting time if the SBP is used as a system on-off switch (wire the System on/off switch in the positive supply of the BMS for this purpose). Similarly, if a system shut down occurred due to low cell voltage, the SBP will remain disengaged for 30 seconds even if it receives a re-engage signal within that time period (which will happen when no other loads are connected to the battery). After 3 attempts to re-engage, the SBP will remain disengaged until the battery voltage has increased to more than 13V (resp. 26V) for at least 30 seconds (which is a sign that the battery is being recharged). The under- voltage thresholds and alarm output of the SBP are inactive in this mode.

Figure 5: Second Smart BatteryProtect in between a battery charger or MPPT solar charge controller and a Li-ion battery (applicable with VE.Bus BMS or mini BMS)
The second SBP replaces a Cyrix-Li-charge relay (advantages: lower power consumption, alarm relay). (not applicable if the charger has remote on-off contacts and can be controlled with an interface cable between the BMS and the charger) Choose a program for this application.
Caution: uncontrolled reverse current will flow through a Smart BatteryProtect if Vout > Vin. Therefore, never use a Smart BatteryProtect for the battery to battery charging.
