    14 in stock

    BlueSolar MPPT Charge Controller - 75V - 15AMPFeatures: Ultra-fast Maximum Power Point Tracking (MPPT) Especially in case of a clouded sky, when light intensity is changing continuously, an ultra-fast MPPT controller will improve energy harvest by up to 30% compared to PWM charge controllers and by up to 10% compared to slower MPPT controllers.  Load output Over-discharge of the battery can be prevented by connecting all loads to the load output. The load output will disconnect the load when the battery has been discharged to a pre-set voltage. Alternatively, an intelligent battery management algorithm can be chosen: see Battery Life. The load output is short circuit proof. Some loads (especially inverters) can best be connected directly to the battery, and the inverter remote control connected to the load output. A special interface cable may be needed, please see the manual.  Battery Life: intelligent battery management When a solar charge controller is not able to recharge the battery to its full capacity within one day, the result is often that the battery will continually be cycled between a ‘partially charged’ state and the ‘end of discharge’ state. This mode of operation (no regular full recharge) will destroy a lead-acid battery within weeks or months. The Battery Life algorithm will monitor the state of charge of the battery and, if needed, day by day slightly increase the load disconnect level (i.e. disconnect the load earlier) until the harvested solar energy is sufficient to recharge the battery to nearly the full 100%. From that point onwards the load disconnect level will be modulated so that a nearly 100% recharge is achieved about once every week.  Programmable battery charge algorithm See the software section on our website for details  Day/night timing and light dimming option See the software section on our website for details  Programming, real-time data and history display options - Color Control GX or other GX devices: see the Venus documents on our website. - A smartphone or other Bluetooth-enabled device: VE.Direct Bluetooth Smart dongle needed Warranty InfoWARNING: This product can expose you to chemicals which are known to the State of California to cause cancer, birth defects or other reproductive harm.

    Distribution Cluster for Single Engine with Two Battery BanksThe 714-140A-DVSR uses a dual sensing DVSR (710-140A). This system ensures that you will always have a fully charged reserve battery. When the switch is in position one, battery one becomes the sensing battery for the VSR. Battery two, which is in isolation, is charged through the VSR when the engine is running to ensure that it is always fully charged. When the switch is in position two, battery two becomes the sensing battery and battery one is charged through the VSR. The fact that there is always a fully charged battery in reserve is a huge safety benefit.WARNING: This product can expose you to chemicals including di(2-ethylhexyl)phthalate (dehp) which is known to the State of California to cause cancer, birth defects or other reproductive harm.

    SmartSolar MPPT 450/100-MC4 VE.Can VE.Direct 450/100The SmartSolar MPPT RS solar charge controllers are Victron's solution for systems with large series connected PV arrays charging 48 V DC battery banks. This product is perfect for large off-grid, and grid-connected battery systems.In a 5.76kW and 11.52kW model, features include a wide 65-450 VDC operating solar voltage input, independent tracking inputs, full connectivity, isolated PV connections, a display screen, fully programmable battery charging parameters, and active cooling. The new metal case design and fully covered electrical connections improve safety and modernize the presentation in line with the latest suite of Victron products.MPPT: Ultra Fast Maximum Power Point TrackingThe SmartSolar RS solar charge controller connects to a PV array of between 65 and 450 Volt Voc and will efficiently charge your 48V battery bank with either 100A or 200A.The charge settings are fully programmable and can be set up for different battery chemistries, like lead-acid, lithium and more.Setup & monitor with VictronConnectThe SmartSolar RS charge controller can be remotely controlled and configured over Bluetooth via the VictronConnect app. This allows device set-up, management, and at-a-glance information, such as battery voltage and current, PV voltage and current, historical data and trends.Daisy Chain Additional UnitsThe SmartSolar RS charge controller is equipped with VE.Can bus ports. This allows for communication with additional SmartSolar RS & VE.Can MPPT units. The additional units are simply “daisy chained” to each other with an RJ45 cable.When connected to each other, all individual charge controllers, will synchronise their charge stages. They can also send their data, via the same cable, for monitoring to a GX device (such as the Cerbo GX).Remote Monitoring and ControlIf the GX device is connected to the internet, the Victron Remote Management Portal (VRM) provides access to the full power of your SmartSolar RS charge controllers.If your installation is connected to a GX device and the internet, Victron Remote Management Portal (VRM) provides access to the full power of your MPPT, anytime, anywhere; for free. For remote installations - even when there is no internet connection nearby - you may be able to monitor your MPPT by connecting the GlobalLink 520.SmartSolar DisplayThe SmartSolar RS charge controller is equipped with a display on the front panel. The display reads battery volts, charge current and voltages from both array’s individually including instantaneous and total figures and unit status including any possible error codes.I/O ConnectionsThe SmartSolar RS charge controller is equipped with a programmable relay and options for remote temperature and voltage sensing. The remote input can accept the Victron smallBMS and other types of BMS with allow-to-charge signals.  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.
