    Dual Operation VSS Switch HD Optic - 12/24V - 500AThis Voltage Sensitive Switch (VSS) automatically senses connected battery bank voltage and provides optimal, efficient charging of the second bank.  The VSS allows for independent battery banks to be combined or isolated based on the presence of a charging source (such as an engine alternator or battery charger), while also offering remotely activated, high current, emergency parallel connection. Designed and constructed for longevity in the marine environment with tinned copper conductors, stainless steel nuts, and high temperature, fibre reinforced plastics.  The units are ignition protected, provide On/Off switching operation, and may be recessed or surface mounted. The remote emergency parallel function can be operated through a momentary button on the dash which will parallel the batteries for 10 minutes.  Once this 10 minutes has passed, if the voltage is high enough, the voltage sensitive switch will stay engaged.  If not, it will disengage.Features: Dual battery sensing Manual override option Dual 12/24 volt operation (both banks must be same voltage) Low power consumption (<6mA) Lowered cut in voltage (13.3/26.6V) suits low output alternators and high temperature environments Technical Specifications: Volts - 12/24V Rating - 500A Dimensions (L x W x H) - 4" x 4" x 4.3" In the Box: Parallel Switch  Instruction manual *Sold as an Individual 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 150/60-TRThe Victron SmartSolar MPPT 150/60 Solar Charge Controller is Bluetooth accessible via either built-in Bluetooth or the Victron Energy Bluetooth dongle. The VictronConnect app is available for free on both iOS and Android. This app allows you to view plenty of parameters: battery voltage, solar history, load output, flexible battery charge algorithms, plus day/night timing and light dimming options. These solar charge controllers will gather energy from your solar panels fast and efficiently. Ultra-fast Maximum Power Point Tracking (MPPT) Especially in the 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 is 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. 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.Please contact your dealer for any returns, repairs or support issues related to this product.

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%.
