Charging lithium batteries

Lithium batteries have improved storage capacity relative to size and weight.

REDARC have designed a charging profile within The Manager30 to complement these in-built systems.

Green power priority

The Manager30 is designed to charge an auxiliary battery from multiple sources simultaneously. If 12 volt solar power is available, solar power will be used before topping up the output charging current from another source mains (if available) or DC vehicle power when on the move.

MPPT solar regulator

The built-in Maximum Power Point Tracking (MPPT) solar regulator allows The Manager30 to deliver the maximum amount of power from portable solar panels, even during low light conditions.
