    Heavy-Duty Battery Selector SwitchThe 721 Battery Selector Switch is our heavy duty selector switch. Housed in the same module as the 720, it includes the same removable plates and back cover. While BEP Marine recommends isolated battery systems as outlined with our distribution clusters, the 721 offers a simple economical way of separating two batteries. Please note selector switches will not separate electronics from harmful engine starting spikes.Specifications: DC Voltage: 48 Stud Size (Imperial): 3 x 3/8" Stud Size (Metric): 2 x 10mm Continuous Rating: 350 Intermittent Rating: 500 Cranking Rating: 1500 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.

    CYRIX-LI-CHARGE 12/24-120A Intelligent Charge Relay Cyrix LI ChargeThe 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.Please contact your dealer for any returns, repairs or support issues related to this product.

    SmartSolar MPPT Charge Controller - 75V - 10AMPFeatures: 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.
