Edge’s Intelligent battery isolators are microprocessor controlled high current relays used in dual battery systems. They are designed to be used as a solenoid priority system to protect the main battery from excessive discharge while allowing the auxiliary battery to supply non-essential loads.  

The dual sensing Intelligent isolators have the added feature of allowing charge both ways where the auxiliary battery may also be charged by an external source, such as solar panels or an external AC battery charger. They will also allow the main battery to be charged by the external source once the auxiliary battery reaches 13.2 volts to help top up the main battery. 



• SRL200 handles 200 Amps continuous at 12V and 300 Amps Surge.
• Eliminates multiple battery drain as it stops battery bank from getting power from each one and extends battery life. Prevents the equipment from discharging the main battery when it is operated while the engine is off. 
• Microprocessor-controlled Intelligent relay does not create a voltage drop to the second battery like conventional isolator.
• Once the main battery reaches 13.2V, the Intelligent relay connects two batteries. Once the system drops below 12.7V, it disconnects two batteries. 
• The dual sensing feature allows charging both ways if auxiliary battery is charged by external power source.  
• A waterproof manual override switch allows you to connect two batteries with the push of a button for 60 seconds. 
• Excellent waterproof performance, high quality in any weather conditions. Two 4AWG copper ring terminals and heat shrink tubing are included for easy installation.
