    SmartSolar MPPT Charge Controller - 100V - 50AMPFeatures: Bluetooth Smart built-in The wireless solution to set-up, monitor, update and synchronise SmartSolar Charge Controllers.  VE.Direct For a wired data connection to a Color Control GX, other GX products, PC or other devices  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 (48V model: interface with a relay). Alternatively, an intelligent battery management algorithm can be chosen: see Battery Life. The load output is short circuit proof.  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  Internal temperature sensor Compensates absorption and float charge voltage for temperature.  Optional external battery voltage and temperature sensing via Bluetooth A Smart Battery Sense or a BMV-712 Smart Battery Monitor can be used to communicate battery voltage and temperature to one or more SmartSolar Charge Controllers 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.

    Pro Installer 400A Dual Bank Control Switch - MC10Another addition to our multi award winning Pro Installer EZ Mount range, the innovative Dual Bank Control switch is like 3 switches in one, House, Start, and Emergency Parallel. Offering easy intuitive control for the boater, the Dual Bank Control switch features a unique isolated-On position which allows use of house loads and VHF radio if the engine needs to be electrically isolated, or allows the engine to be isolated during servicing while still providing power to house loads (for lighting, stereo, fridge etc). For boats or vehicles with single Engine and House battery bank, Dual Bank Control allows the use of optimized battery banks for their respective loads; an appropriately sized deep cycle bank for House loads, and thin plate starting batteries for the Engine. Further, sensitive electronics are isolated from starter motor induced voltage spikes because House and Engine loads are separated during normal operation, unlike Selector battery switches. As easy as 1, 2, 3, these revolutionary EZ Mount battery switches allow you to wire from the front for the easiest surface mounting. With their shared interconnection height, EZ-Mount battery switches "cluster" directly with the Pro Installer Busbar Range, resulting in the fastest, most compact installations.

    1 in stock

    Remote Operated Battery Switch w/Optical Sensor 500A 12/24VThe MD range of battery switches allow you to install the battery switch very close to the battery, to remotely manage the increased electrical loads found on today's boats. This reduces cable lengths and sizes, providing significant savings in expense and weight of copper battery cable. They are ideal for remote isolation of bow and stern thrusters. The 720-MDO has been enhanced to offer easy standard installation, or advanced options capable of switching different voltage circuits from the main supply (for example: a 48 volt bow thruster with a 24 volt house supply). The optical sensor uses the same easy connection for standard installation and gives you the ability to control different voltage circuits such as 36 or 48 volts. It can be used to switch positive or negative lines and the main contacts can be isolated from the control circuit allowing operation via another battery source. This optical sensor also has low stand-by current draw (<5mA). Remote operation Battery switch can be mounted alongside battery, reducing cable lengths and cable sizes. (Large cost and weight saving in copper cables) Reduced installation labor due to shorter battery cable runs Manual override option to meet CE/ABYC requirements LED status identification for remote control switch Same capacities/specifications and mounting options as standard BEP battery switches Uses interchangeable labeling system (Item # 713 or 715) Specifications:LxWxH: 4" x 4" x 4.33"Rating (A DC) Cont: 500Rating (A DC) Inter: 700Rating (A DC) Crank: 2500Voltage (V DC): 9.5-32Function: On/OffStud Size: 2x (1/2"/12mm)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.
