Sargent EC400 Quick Start Manual

Smart Charging

The EC400\450 and 500 ranges of PSU's incorporate a
smart charge feature, which monitors both
Leisure and Vehicle batteries and automatically adjusts
and directs the charger power (and solar power if a solar
panel is installed) to maintain the leisure and vehicle
batteries at an optimal level.
The Smart Charge feature will default to the Leisure
Battery and will monitor the Vehicle Battery, if the
Vehicle Battery drops below 12.4V the charger will divert
the charge to the Vehicle Battery for a 4 Hour period
before returning to the Leisure Battery for 4 Hours. At
this point the system will default back to the Leisure
Battery and monitor the Vehicle Battery.

Solar Smart Charging

Where a Solar Panel is fitted the charge from the Solar
Regulator will be diverted to the opposite battery to that
being charged by the mains charger when the mains
power is turned on.
Any installations incorporating a Solar Panel will also follow a similar Smart Charge routine when the mains
charger is disconnected.
EC4xx Systems will default to the Vehicle Battery whilst EC500 systems default to the Leisure Battery, Both
will then monitor the alternative battery until it drops below 12.4V at which point it will switch the current flow
to maintain a healthy charge on this battery.
