In your camper van or motorhome, you have both the engine battery and a house battery bank. You'll want the ability to keep both the engine battery and house batteries well-charged, and also to be able to use the stored energy from each.
The CTEK SmartPass 120 Battery Isolator/Energy Manager is a smart automatic dual battery isolator switch and energy management unit which controls and optimizes energy produced by alternators, solar panels, wind power or conventional AC/DC chargers. It distributes power to battery banks or consumers depending on energy needs, such as the house battery bank, refrigerators, etc.
Used together with a CTEK D250SA DUAL Battery Charger, SMARTPASS provides optimal charging via CTEK’s unique multi-stage charging cycle, which also protects your batteries. SMARTPASS 120 also has an integrated “Battery Watch” feature which protects batteries from harmful total discharge and ensures that critical equipment such as radio, emergency lights and navigation systems get the proper priority to provide maximum functionality. SMARTPASS 120 has a temperature sensor which protects batteries against high temperatures.
