Redarc SBI24D Smart Start Dual Sensing Dual Battery Isolator 24V 100A
The Redarc Smart Start SBI24D is a dual sensing 100 A battery isolator for 24 V dual battery systems. It separates the starting and auxiliary batteries and connects them automatically whenever either one is being charged.
Thanks to dual sensing, when the auxiliary battery is charged by a solar panel or mains charger and reaches 26.4 V, energy also flows to the starting battery. Ideal for 24 V trucks, motorhomes and boats. Designed and manufactured in Australia.
Key features
Bi-directional sensingConnects when either battery reaches 26.4 V, putting solar and mains charging to work for the starting battery too.
Start battery protectionDisconnects at 25.4 V so the engine will always start.
Silver alloy contactsLonger life and suitable for marine use.
Compact overmoulded housingEasy to install and built for the vehicle environment.
Low power draw and diagnosticsStandby below 5 mA, fault indication and full surge protection.
