User Manual
Stage 4- Maintenance stage is a regular timed recharge (or return
to bulk stage). The Enerdrive ePOWER Battery Charger switches the
charger from oat to boost after 7 days of constant operation to ensure
the battery banks remain active.
Smart Charging Feature
The ePOWER Battery Charger will regulate its output based on the loads
connected to your battery banks. This function is important to maintain
the life of your battery banks as some battery chargers mistake loads for
discharge and continue to keep the batteries in the bulk or absorption
stage for extended periods of time, which will damage the battery bank.
The ePOWER Battery Charger has two methods of load based regulation
to ensure your battery charger transitions to oat when it should do so.
ePOWER charger algorithm
Note: Actual voltages dependent on chosen algorithm.
In the event o AC mains loss the charger will react according to time without mains power.
Loss of AC power for less than 4min - Charge resumes at existing stage.
Loss of AC power for more than 4min - Charge resumes at bulk stage.
