Renogy's fulfillment center will remain open to ensure that you are equipped with the reliable energy solution. Please note that due to an increase in order volume, there may be a slight delay. Thank you!



Although mainly used in RVs, the Renogy 200A Battery Isolator can be used in most motorized vehicles, allowing the alternator to charge two different battery banks at the same time. It isolates the starting battery from the house battery when using loads, and connects them when the alternator is running. Beyond RVs, the dual battery isolator is also ideal for two battery applications such as marine vehicles as it makes it easy to manage and switch the charge between your batteries.
