RS20 model

  • Automatically disconnects start-battery from house-battery when RV engine shuts off (avoids flattening start-battery when running appliances while parked). 

 

  • Allows start-battery to charge before connecting house-battery.  Otherwise known as a VSR (voltage sensitive relay)

 

  • Automatically connects house-battery to alternator when driving to charge house-battery

 

  • Alarms when house-battery is too low or too high (under 11.8V, over 15.0V).  Peace of mind when drawing power from or charging your expensive house-batteries

 

  • Monitors up to 3 water tanks including grey water (tank sensor cables to be purchased separately)    Suitable for metal and non-metal tanks

 

  • Simple to integrate with solar panels

 

  • Automatically reduces charge rate if house-battery is over charging (if house-battery exceeds 15.1V)
