The Xantrex Battery Combiners are used to combine the chassis battery pack with the house battery pack when certain conditions are met.
The chassis battery pack is typically a lead-acid battery for the vehicle engine and the house battery pack is a lithium-ion battery that supplies power to the coach interior.
The combiner allows both the primary vehicle alternator and the auxiliary alternator in a Xantrex Power System to charge the house battery simultaneously.
This results in faster charge times for the house battery.
