The Sterling Power PSR102 Pro Split R is a 2-output battery isolator for 24V systems with alternators up to 100A. It suits boats, RVs and trucks where one alternator has to charge an engine battery plus one or more house or thruster banks.
Traditional split-charge diodes lose around a volt, which leaves house batteries undercharged, and compensating for that loss can overcharge the starter battery. The Pro Split R uses micro-processor controlled switching with almost no voltage drop, and it can briefly isolate a full engine battery so the alternator's regulator sees only the empty house bank and charges it harder. Sterling states it is not suitable for modern European vehicles or any vehicle with an advanced ECU; use a battery to battery charger there.
Features
- Micro-processor controlled zero-volt-drop splitting
- Sends the most current to the bank that needs it
- Temporarily isolates a full engine battery so the house bank charges faster
- Blocks back-feed between banks under heavy load
- Disconnects the alternator if its own regulator fails, so batteries are not boiled
- Isolates any bank being back-fed a high voltage from a faulty charger
- LED display shows which channels are active
- Fail-safe: engine battery and alternator stay connected if the unit fails, and the engine battery is charged first
