What is a battery isolator and how does it work?
A battery isolator is an electrical device that allows multiple batteries to be charged from a single charging source, while keeping them isolated from each other. This means that if one battery is deeply discharged, it won’t drain the other batteries. The isolator works by using diodes or other electrical components to block the flow of current between the batteries, while allowing the charging source to charge each battery individually.
The isolator is typically installed between the charging source and the batteries, and is designed to handle the maximum charging current and voltage of the system. By keeping the batteries isolated, the isolator helps to prevent over-discharging, which can damage the batteries and reduce their lifespan. This makes it an essential component in many electrical systems, including RVs, boats, and off-grid solar systems.
Do I really need a battery isolator in my RV or boat?
If you have multiple batteries in your RV or boat, and you want to charge them from a single charging source, then a battery isolator is highly recommended.
