Go Power! PHANTOM 30A Dual-Source DC to DC and MPPT Solar Controller

Solar + Alternator Charging for Overland House Batteries

For an overland rig with a starter battery and a separate house battery, the Go Power! PHANTOM brings solar and alternator charging together in one 30A controller for supported vehicle battery systems. Use solar power when your panels are producing, and alternator power while driving. Its intelligent alternator-charging function boosts charging voltage to support charging an auxiliary battery bank.

In this kind of build, the house battery runs your camp loads while the starter battery serves the vehicle. The PHANTOM has a dual-input, dual-output design and supports 12V or 24V DC systems, but the exact battery connections, bank isolation and charging priority depend on the system wiring and configuration. Before installing, check the GP-PHANTOM manual and confirm compatibility with your battery chemistry and any separate DC-to-DC charger already in the build.

Check Your Overland System Compatibility

Confirm your system voltage, battery chemistry, wiring layout and any existing DC-to-DC charging equipment against the PHANTOM manual and your battery manufacturer's requirements before purchase or installation.
