RV Isolator Solenoid: A Game-Changer for Your Vehicle's Electrical System

When it comes to maintaining your vehicle's electrical system, there are several options available to ensure that your batteries receive the proper charge and maintain their overall health. One such option is the RV isolator solenoid, a device designed to isolate your starting battery from your deep cycle battery bank while allowing both batteries to be charged by your alternator.

One of the key benefits of using an RV isolator solenoid is that it prevents the deep cycle battery bank from discharging into the starting battery, which can occur when the vehicle is turned off. This is particularly important if your battery bank is only partially discharged, as it can prevent your starting battery from being drained to a level where it may not be able to start the engine.

Another benefit of using an RV isolator solenoid is that it allows your alternator to charge both batteries separately and at different rates. This means that your deep cycle battery bank can receive a slower, more consistent charge, while your starting battery receives a faster, higher-voltage charge when needed.

In contrast, some users may choose to connect their sense line directly to the battery, which can cause the alternator to increase its output voltage and compensate for any voltage drop. While this may seem like a good idea at first glance, it can actually have negative consequences on the quality of your batteries' recharge and overall life expectancy.

Overall, an RV isolator solenoid is a simple yet effective solution for maintaining your vehicle's electrical system and ensuring that both your starting battery and deep cycle battery bank receive the proper charge. With its ability to isolate the two batteries while allowing them to be charged separately, it's no wonder why many RVers have chosen this option as their go-to solution.
