MagnaSine Smart Battery Combiner

Advanced MOSFET Dual Battery Isolator for Efficient Multi-Bank Charging

Managing power across multiple battery banks from a single charging source requires precision to avoid energy loss and premature battery wear. The MagnaSine Smart Battery Combiner provides a sophisticated, solid-state solution for dual battery systems. Utilizing advanced MOSFET switching technology, this voltage-sensing isolator directs a portion of the charging current from your primary battery to an auxiliary battery bank. Whether your charging source is an alternator, solar charge controller, or inverter charger, this combiner ensures both banks receive reliable power without the inefficiencies of older isolation methods.

Eliminate Voltage Drop with Solid-State MOSFET Switching

Standard diode-based battery isolators often suffer from significant voltage drop, which generates excess heat and prevents secondary batteries from reaching a full state of charge. Similarly, basic mechanical relays can suffer from contact wear over time. The MagnaSine Smart Battery Combiner overcomes these common limitations by employing high-efficiency MOSFET transistors. This solid-state design eliminates significant voltage drop across the unit, ensuring that your auxiliary battery receives the correct charging voltage dictated by your primary charging source.

Customisable Voltage Setpoints for System Protection

Every electrical setup has unique requirements depending on battery chemistry, cable run lengths, and load demands. Unlike fixed-voltage relays that offer no flexibility, this unit features user-adjustable dials for turn-on and turn-off thresholds. By fine-tuning the connect and disconnect voltage setpoints, you can tailor the combiner's behaviour to match your exact system parameters. This level of control actively mitigates the risk of overcharging or undercharging, protecting your valuable battery investments while keeping your starting or primary battery isolated when charging stops.

Key Features and Hardware Design
