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)
Items included:
-RS20 wall-mount unit
-30amp ring terminals (for cable AWG10 - 12)
-Mounting screws
-Manual
