    Orion-TR Smart 12/24-15A (360W) Isolated DC-DC Charger or Power SupplyThe Orion-Tr Smart isolated DC-DC charger serves as a DC-DC battery charger or a power supply (also designed for use as a constant voltage source), offering a wide input and output voltage range. This is especially significant in the case of vehicles with a Euro 5 or Euro 6 smart alternator, which often supplies too low charging voltage even when the engine is running or when extended cable lengths, as is often the case in boats and RVs, lead to voltage drops. In such scenarios, precise and controlled charging is imperative to fully charge the service battery while protecting the starter/input battery from discharge.Bluetooth Smart Enabled Any Bluetooth-enabled smartphone, tablet, or other device can be used to monitor, change settings, and update the charger when new software features become available Instant Readout: The VictronConnect App can display key data, including warnings and alarms, on the device list page without the need to connect to the product Fully programmable Battery charge algorithm (configurable) or fixed output.  Smart Alternator Compatibility: engine running detection mechanism Adaptive 3-Stage Charge Algorithm: Bulk – Absorption – Float For lead-acid batteries, it is important that during shallow discharges the absorption time is kept short to prevent overcharging of the battery. After a deep discharge, the absorption time is automatically increased to make sure that the battery is completely recharged For lithium batteries, the absorption time is fixed; the default is 2 hours Alternatively, a fixed output voltage can be chosen Suitable for Use in Vehicles with a Smart Alternator (Euro 5 and Euro 6 Engines)The built-in engine shutdown detection will stop the converter when the engine is not running. This prevents unwanted discharge of the starter battery (see manual for details).Remote On/OffA remote on/off switch or relay contact can be connected to a two-pole connector. Alternatively, the H terminal (right) of the two-pole connector can be switched to battery plus, or the L terminal (left) of the two-pole connector can be switched to battery minus (or the chassis of a vehicle, for example).All Models Are Short Circuit Proof and Can Be Paralleled to Increase Output CurrentAn unlimited number of units can be connected in parallel.High Temperature ProtectedThe output current will reduce at high ambient temperatures.IP43 ProtectionWhen installed with the screw terminals oriented downward.Screw TerminalsNo special tools are needed for installation.

    BatteryProtect BP-65 - 65AMP - 6-35 VDCFeatures: The 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.  12/24V auto ranging The BatteryProtect automatically detects system voltage  Programming made easy The BatteryProtect can be set to engage / disengage at several different voltages. The seven segment display will indicate which setting has been chosen.  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 16V respectively 32V. 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 alarm has been activated. 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.

    SmartSolar MPPT 150/35 - 150V - 35AA solar charger gathers energy from your solar panels, and stores it in your batteries. Using the latest, fastest technology, SmartSolar maximises 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 sulphated 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 and ControlRemotely control and monitor the extensive features of your SmartSolar MPPT charger with built-in bluetooth by pairing it with your smartphone or other device via VictronConnect. If your installation is connected to the internet Victron Remote Management Portal (VRM) provides access to the full power of your MPPT, anytime, anywhere; both services are free to use. For remote installations - even when there is no internet connection or phone signal nearby - you may be able to monitor your MPPT by bluetooth-pairing with a LoRaWAN (long-range wide area network) device, available optionally.VictronConnectVictronConnect lets you get live status information and configure any Victron products which either have Bluetooth built-in, or are connected to a VE.Direct Bluetooth Smart Dongle.Please contact your dealer for any returns, repairs or support issues related to this product.
