B2B charging applications
- Allows charging a main service battery via the alternator using the starter battery as an input source.
- Can be used to transfer charge between batteries when units are off-board or outside a vehicle.
- When the vehicle is running, the alternator can supply full-power charging to the main battery through this charger.
- Charge control follows standard charging curves by boosting or stepping down to the specified voltage and current.
MPPT solar charge
- Built-in MPPT capability improves solar panel charging efficiency by approximately 10–30% under typical conditions.
- Regulates output by boosting or bucking to deliver the specified current and follow standard charge profiles for the main battery.
- Supports long-term vehicle standby by providing a small trickle charge to the starter battery to ensure reliable starting power.
