  • Sale -15% Victron Battery Balancer [BBA000100100] Victron Battery Balancer [BBA000100100]

    Victron Battery Balancer [BBA000100100]

    Battery BalancerThe Battery Balancer equalizes the state of charge of two series connected 12V batteries, or of several parallel strings of series connected batteries. When the charge voltage of a 24V battery system increases to more than 27V, the Battery Balancer will turn on and compare the voltage over the two series connected batteries. The Battery Balancer will draw a current of up to 1A from the battery (or parallel connected batteries) with the highest voltage. The resulting charge current differential will ensure that all batteries will converge to the same state of charge.If needed, several balancers can be paralleled. A 48V battery bank can be balanced with three Battery Balancers.WARNING: This product can expose you to chemicals which are known to the State of California to cause cancer, birth defects or other reproductive harm.

  • Sale -15% Victron Smart BatteryProtect - 220AMP - 6-35 VDC - Bluetooth Capable [BPR122022000] Victron Smart BatteryProtect - 220AMP - 6-35 VDC - Bluetooth Capable [BPR122022000]

    Victron Smart BatteryProtect - 220AMP - 6-35 VDC - Bluetooth Capable [BPR122022000]

    Smart BatteryProtect - 220AMP - 6-35 VDC - Bluetooth CapableFeatures: Protects the battery against excessive discharge and can be used as a system on/off switch The Smart BatteryProtect disconnects the battery from non-essential loads before it is completely discharged (which would damage the battery) or before it has insufficient power left to crank the engine. The on/off input can be used as a system on/off switch.  12/24V auto ranging The Smart BatteryProtect automatically detects system voltage one time only.  Bluetooth: programming made easy When using Bluetooth to program the Smart BatteryProtect any required engage/disengage levels can be set. Alternatively, one of nine predefined engage/disengage levels can be set with the programming pin (see manual). If required, Bluetooth can be disabled.  A special setting for Li-ion batteries In this mode the BatteryProtect can be controlled by the VE.Bus BMS. Note: the BatteryProtect can also be used as a charge interrupter in between a battery charger and a Li-ion battery. See connection diagram in the manual. Ultra-low current consumption This is important in case of Li-ion batteries, especially after low voltage shutdown. Please see our Li-ion battery datasheet and the VE.Bus BMS manual for more information.  Over voltage protection To prevent damage to sensitive loads due to over voltage, the load is disconnected whenever the DC voltage exceeds 16.3V respectively 32.6V.  Ignition proof No relays but MOSFET switches, and therefore no sparks.  Delayed alarm output The alarm output is activated if the battery voltage drops below the preset disconnect level during more than 12 seconds. Starting the engine will therefore not activate the alarm. The alarm output is a short circuit proof open collector output to the negative (minus) rail, max. current 50 mA. The alarm output is typically used to activate a buzzer, LED or relay.  Delayed load disconnect and delayed reconnect The load will be disconnected 90 seconds after the battery voltage drops below the preset level. If the battery voltage increases again to the connect threshold within this time period (after the engine has been started for example), the load will not be disconnected. The load will be reconnected 30 seconds after the battery voltage has increased to more than the preset reconnect voltage.

    Victron Combiner 12/24V-230A Cyrix-CT Intelligent Combiner Microprocessor Controlled [CYR010230010]

    Combiner 12/24V-230A Cyrix-CT Intelligent Combiner Microprocessor ControlledThe Cyrix Battery Combiner is a microprocessor controlled heavy duty relay that automatically connects batteries in parallel when one of them has reached a pre-set voltage (indicating that the battery is being charged), and disconnects when the voltage decreases below float level (indicating that one or more batteries are being discharged). Cyrix Battery Combiners are an excellent replacement for diode isolators. The main feature is that there is virtually no voltage loss so that the output voltage of alternators or battery chargers does not need to be increased.

  • Sale -15% Victron Smart Solar MPPT 150/85-TR VE.Can [SCC115085411] Victron Smart Solar MPPT 150/85-TR VE.Can [SCC115085411]

    Victron Smart Solar MPPT 150/85-TR VE.Can [SCC115085411]

    Smart Solar MPPT 150/85-TR VE.CanA solar charger gathers energy from your solar panels, and stores it in your batteries. Using the latest, fastest technology, SmartSolar maximizes this energy harvest, driving it intelligently to achieve full charge in the shortest possible time. SmartSolar maintains battery health, extending its life.The SmartSolar charge controller will even recharge a severely depleted battery. It can operate with a battery voltage as low as 0 Volts, provided the cells are not permanently sulfated or otherwise damaged.MPPT: Ultra Fast Maximum Power Point TrackingBy constantly monitoring the voltage and current output of your solar (PV) panels, MPPT technology ensures that every drop of available power is rinsed out of your panels, and harvested for storage. The advantage of this is most noticeable when the sky is partially clouded, and light intensity is constantly changing.Remote Monitoring & ControlRemotely control and monitor the extensive features of your SmartSolar MPPT charger with built-in Bluetooth by pairing it with your smartphone or another device via VictronConnect. If your installation is connected to the internet with a GX device, the Victron Remote Management Portal (VRM) provides access to the full power of your MPPT, anytime, anywhere; both VictronConnect and VRM are free to use. For remote installations - even when there is no internet connection nearby - you may be able to monitor your MPPT by connecting the  GlobalLink 520.Load OutputThe intelligent Load output function prevents damage caused by running batteries 'flat'. You can configure the voltage at which SmartSolar disconnects a load - thereby preventing excessive drain on your batteries. And here's the clever bit: SmartSolar will attempt a 100% recharge every day. If it can't - during periods of poor weather - it raises the disconnect voltage, daily, until it achieves success. We call this feature BatteryLife because it maintains health, and extends the life of your battery.Please contact your dealer for any returns, repairs or support issues related to this product.
