Product Description

Product Overview & Features

Professional DC-DC charger designed to charge the main battery through the alternator and starter battery, or utilize Solar panels (on specific models). This charger is specifically engineered for motorhomes, campers, ships, and marine applications.

B2B Charge (Battery to Battery)

Ensures efficient charging of the main battery using the vehicle's alternator and starter battery system.

High-power charging: While the vehicle is running, the alternator quickly charges the main battery at full capacity.
Voltage Regulation: Automatically adjusts voltage (boosting or stepping down) to follow standard charging curves.
Dual Battery Support: Can be used to charge one battery from another in non-vehicle setups.

MPPT Solar Charge

Advanced MPP Technology: Increases solar panel charging efficiency by 10-30% by tracking the maximum power point.
Precision Charging: Manages current flow through boosting or stepping down to maintain the standard charge curve.
Starter Battery Maintenance: Provides a small trickle charge to the starter battery during long periods of inactivity, ensuring the vehicle is always ready to start.
