## Summary description

The Solvian Smart Battery Isolator is a 12V 140A device designed to manage dual battery systems in vehicles and marine applications. It automatically connects the auxiliary battery to the main power source when the engine is running and disconnects it when the engine is off, preventing the starter battery from discharging. This reliable component ensures efficient power distribution and protects your electrical system during operation.

## Long description

The Solvian Smart Battery Isolator 12V 140A is a robust voltage-sensitive relay engineered to manage dual battery systems in vehicles, campers, and marine vessels. By monitoring the voltage of the primary battery, it ensures that the auxiliary battery is charged only when the engine is running, while automatically disconnecting it once the engine is switched off. This intelligent power management prevents the starter battery from being drained by secondary electrical loads, ensuring your vehicle remains ready to start at all times.
Advantages
This battery isolator offers a seamless automated solution for maintaining power in complex electrical setups. Its primary benefit lies in its ability to protect the starter battery from deep discharge, which significantly extends the lifespan of your power system. The unit is designed to handle high current loads, making it suitable for demanding applications. Its weather-resistant construction ensures reliable performance in various environments, while the simple installation process allows for quick integration into existing vehicle electrical systems without requiring complex manual switches.
Suitable for
Off-road vehicles and 4x4 setups
Camper vans and motorhomes
Marine vessels and boats
Work trucks with auxiliary equipment
This device may not be suitable for systems requiring manual override control or for vehicles with complex smart alternator systems that operate outside standard voltage parameters. It is also not intended for high-voltage industrial applications or systems exceeding the 140A current rating.
Key specifications
Voltage: 12V
Maximum current: 140A
Operation: Automatic voltage-sensitive switching
Application: Dual battery systems
Installation involves connecting the main starter battery and the auxiliary battery to the designated terminals on the isolator, along with a secure ground connection. Once installed, the device operates autonomously, requiring no user intervention. It detects the charging voltage from the alternator and engages the connection to the auxiliary battery automatically, then disengages when the voltage drops below the threshold after the engine is turned off.
What to consider before purchase
Verify that your alternator output is compatible with a 12V system
Ensure your total electrical load does not exceed the 140A limit
Check available space for mounting the unit near the battery bank
For optimal performance and safety, ensure all cable connections are tight and properly insulated. It is recommended to use appropriately sized wiring based on the 140A current capacity to prevent overheating and voltage drop.
