    SmartSolar MPPT VE CAN 250V-100A with VE.CAN PortThe MPPT VE.Can SmartSolar charger uses the latest and fastest technology to convert energy from a solar array into energy that optimally charges battery banks?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 TrackingThe MPPT VE.Can SmartSolar charger connect to a PV array of 150 or 250 Volt Voc and will automatically detect and charge your 12, 24, or 48V battery bank with current ranging from 70 to 100A depending on the model.The charge settings are fully programmable and can even be set up for different battery chemistries, like lead-acid, lithium, and others.Control Your Charger RemotelyThe MPPT VE.Can SmartSolar charger 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, and historical data.Daisy Chain Additional UnitsThe VE.Can SmartSolar charger isequipped with CAN bus ports. This allows for communication with additional VE.Can SmartSolar chargers. The additional units are simply "daisy-chained" to each other with a single RJ45 cable between the individual units.When connected to each other, all individual VE.Can SmartSolar chargers, synchronize their charge stages. They can also send their data, via a single cable, to a GX monitoring device.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 solar charger(s). 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 Control DisplayThe VE.Can SmartSolar charger is also equipped with a VE.Direct port like our other MPPT solar chargers. This port can be for single-unit monitoring or for streetlight control. The remote on/off connector can be externally controlled by a third-party device like a lithium battery. An optional plug-in LCD display/control provides live data, set-up, and management, straight from the face of the device.  Please contact your dealer for any returns, repairs or support issues related to this product.

    Mastervolt Charge Mate Pro 90 [83309002]

    2 in stock

    Charge Mate Pro 90Current limited electronic charge relay with high efficiency and reverse current protectionA secondary battery onboard requires a dedicated charging solution. The Charge Mate Pro makes it possible to distribute the charger or alternator current effectively between two battery banks such as a starter and a service battery. The Charge Mate Pro connects both batteries during charging and keeps them isolated when discharging. This significantly reduces the risk of a flat starter battery for example.The Charge Mate Pro offers an additional advantage over mechanical charge relays, by limiting the charge current to the second battery. The primary battery, like a starter battery, is therefore charged with priority. The return current is automatically blocked even when the secondary battery has a higher voltage. An emergency start function is possible by connecting an optional bypass switch to the ChargeMaster Pro.A marine application example is the connection of a bow thruster battery to a service battery. The Charge Mate Pro ensures that the service battery is always charged with priority. The blocking of the return current from the bow thruster battery guarantees that the bow battery remains charged while the current limiting also prevents power dips of the onboard electrical network.The Charge Mate Pro series consists of a 40 Amp and a 90 Amp version, both suitable for charger or alternator applications. The Charge Mate Pro 90 ensures a higher charge current for example when charging Lithium-Ion batteries. It is also perfectly suitable for large automotive alternators up to 180 A and can be used in parallel operation with a 225 Amp alternator to fulfill even higher continuous power demands of your equipment on board.Charge Mate Pro: for controlled charging from a single source.Applications:Leisure and professional marine and mobile applications. An effective solution for high power demand onboard and/or the need for prioritized or current limited charging.Features: Charges two battery banks from a single source. Electronic charge coupling with very low voltage drop. Makes effective dual charging possible. Suitable for all battery types, including Lithium-Ion. Charge current secondary battery limited to 40 or 90 A. High system reliability by prioritizing charging of the main battery. Unidirectional which blocks return current under all circumstances. Prevents power dips in the onboard electrical network. Suitable for all kinds of chargers and alternators. Monitoring with LED status indication. IP65 electronics in a corrosion-resistant casing with aluminum heat sinks. Fast and easy installation.
